\n

2. Five Key Facts<\/h2>\n
\n
\n

Fact 1<\/strong><\/p>\n

Rated output torque reaches 30,000 N\u00b7m, making the EP-Feed Mixer Planetary Gearbox one of the highest-capacity planetary mixer gearboxes in its class for heavy-duty feed mixing equipment.<\/p>\n<\/div>\n

\n

Fact 2<\/strong><\/p>\n

The gears are precision ground to ISO 1328-1:1995 Grade 5\u20136, with a surface roughness Ra \u2264 0.8 \u00b5m, ensuring smooth, low-noise operation even under continuous heavy loads.<\/p>\n<\/div>\n

\n

Fact 3<\/strong><\/p>\n

The vertical mounting configuration is specifically optimized for the auger-drive shaft arrangement found in TMR vertical feed mixer wagons widely used on dairy and beef cattle operations across Colombia.<\/p>\n<\/div>\n

\n

Fact 4<\/strong><\/p>\n

Supports single-input and double-input spline shaft configurations, plus optional hollow-shaft, shrink-disc, external-spline, or solid keyed output shafts \u2014 providing wide compatibility with most mixer OEM designs.<\/p>\n<\/div>\n

\n

Fact 5<\/strong><\/p>\n

The housing carries an IP65 protection rating, fully resistant to dust ingress and water jets \u2014 a critical requirement on farms in Colombia’s varied climates, from the humid Magdalena Valley to the high-altitude Sabana de Bogot\u00e1.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

3. How the EP-EG Planetary Gearbox Works<\/h2>\n

The EP-EG Feed Mixer Planetary Gearbox operates on the principle of epicyclic planetary gear transmission. Power enters through the input shaft and is transferred to the sun gear at the center of the gear stage. The sun gear simultaneously engages multiple planet gears arranged symmetrically around it, which in turn mesh with the fixed ring gear (also called the internal gear or annular gear). Because the ring gear is held stationary within the housing, the planet gears orbit around the sun gear, and their carrier \u2014 which is connected to the output shaft \u2014 rotates at a reduced speed with correspondingly amplified torque.<\/p>\n

This power-splitting architecture is the defining advantage of a planetary drive gearbox: instead of a single gear pair carrying the entire load, the torque is divided equally across all planet gears (typically three or more per stage). The result is a remarkably compact unit capable of transmitting very high torque relative to its physical size. In the EP-EG Feed Mixer Planetary Gearbox’s 2-stage or 3-stage configuration, the output of the first planet carrier becomes the input to the next gear stage, achieving the overall gear ratio of 13.4:1 through to 24.18:1 while maintaining a coaxial (in-line) input-output axis \u2014 which is precisely the geometry required for vertical auger shafts in TMR feed mixers.<\/p>\n

The carrier bearings and ring gear are pre-loaded to eliminate backlash under reversing loads, a common situation in feed mixer operation when the auger encounters densely packed silage or hay.<\/p>\n<\/div>\n

<\/p>\n

\n

4. Advantages of our EG Series Feed Mixer Planetary Gearbox<\/h2>\n
\n
\n

1. Exceptional Torque Density<\/h3>\n

With a peak output of 30,000 N\u00b7m distributed across three planet gears per stage, the EP-EG Feed Mixer Planetary Gearbox delivers torque-to-weight ratios that outperform traditional parallel-shaft reducers by a significant margin. This means you can install a lighter, more compact gearbox without sacrificing the raw power needed to handle heavy, fibrous TMR mixes containing silage, hay, and wet grains \u2014 materials that impose sudden peak loads on the drive train during start-up and mixing reversals.<\/p>\n<\/div>\n

\n

2. Hardened Alloy Steel Gears for Extended Service Life<\/h3>\n

Every gear in the EP-EG Series Feed Mixer Planetary Gearbox is machined from 20CrMnTi alloy steel, carburized using a controlled atmosphere multi-furnace process, and then quenched to achieve a surface hardness of 58\u201362 HRC with a case depth of 0.6\u20131.5 mm. The core hardness is retained at 33\u201348 HRC, providing the toughness to absorb shock loads without brittle fracture. After heat treatment, gears are precision ground to ISO Grade 5\u20136, resulting in quiet, smooth transmission across the full torque range throughout the gearbox’s operational lifetime.<\/p>\n<\/div>\n

\n

3. Modular, Multi-Configuration Design<\/h3>\n

The EP-Feed Mixer Planetary Gearbox is engineered on a modular platform that accommodates a wide variety of input and output shaft arrangements without requiring a complete redesign. Input options include a keyed solid input shaft, single spline, or double spline. Output can be delivered through a solid keyed shaft, a hollow shaft with shrink-disc connection, an external spline shaft, or an internal spline bore \u2014 ensuring that this planetary mixer gearbox can be retrofitted to most vertical feed mixer wagons currently operating in Colombia and across Andean markets without costly custom engineering.<\/p>\n<\/div>\n

\n

4. High Efficiency Across the Full Operating Range<\/h3>\n

Each gear stage of the EP-Feed Mixer Planetary Gearbox achieves a mechanical transmission efficiency of 97\u201398%, resulting in an overall system efficiency of \u226596% in a 2-stage configuration. Less energy is wasted as heat, reducing operating costs on farms where diesel or electric power represents a significant running expense. This efficiency advantage directly translates to lower fuel consumption for PTO-driven feed mixer wagons \u2014 an important economic consideration for cattle farmers in regions such as Medell\u00edn, Cali, and the Coffee-Growing Axis of Colombia where energy and fuel costs are closely monitored.<\/p>\n<\/div>\n

\n

5. Robust Sealing and Environmental Protection<\/h3>\n

Operating on agricultural sites means constant exposure to dust, moisture, feed residues, and occasional pressure washing. The EP-EG Feed Mixer Planetary Gearbox incorporates radial shaft seals, O-ring face seals on all inspection covers, and a cast-iron housing treated with high-adhesion corrosion-resistant primer and enamel topcoat. The IP65 ingress protection rating guarantees reliable operation in the open-air environments of Colombian feedlots, milking barns, and mobile TMR wagon applications, where weatherproofing directly impacts maintenance intervals and total cost of ownership.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\n

5. Materials & Construction<\/h2>\n
\n
\n

Housing<\/strong><\/p>\n

HT250 gray cast iron, with a minimum tensile strength of 250 MPa. Cast iron provides excellent vibration damping and dimensional stability, and its inherent rigidity prevents housing distortion under heavy gear separating forces. The exterior receives an epoxy-based corrosion-resistant primer followed by a polyurethane enamel topcoat.<\/p>\n<\/div>\n

\n

Gears (Sun, Planet, Ring)<\/strong><\/p>\n

20CrMnTi chromium-manganese-titanium alloy steel. After rough and semi-finish machining, gears undergo controlled atmosphere carburization at 920\u2013940\u00b0C for 6\u201312 hours, followed by oil quenching and low-temperature tempering at 180\u2013200\u00b0C. Final surface hardness: 58\u201362 HRC. All flanks are precision-ground using CNC profile grinding machines.<\/p>\n<\/div>\n

\n

Shafts & Planet Carrier<\/strong><\/p>\n

42CrMo4 chromium-molybdenum alloy steel (equivalent to AISI 4140), heat-treated to 28\u201332 HRC for a balance of tensile strength and machinability. The planet carrier is typically produced as a one-piece ductile iron casting or a welded steel fabrication, depending on frame size, ensuring it can withstand the full bending moment from the auger load.<\/p>\n<\/div>\n

\n

Bearings<\/strong><\/p>\n

Tapered roller bearings and cylindrical roller bearings from grade-matched suppliers are used at all shaft positions. Bearing selection follows ISO\/TR 1281-1 fatigue life calculation methodology, targeting an L10h life in excess of 20,000 operating hours under nominal rated torque \u2014 equivalent to approximately 10 years of normal farm use.<\/p>\n<\/div>\n

\n

Seals<\/strong><\/p>\n

FKM (fluoroelastomer) radial shaft seals are used at all rotating shaft exits. FKM outperforms standard NBR (nitrile) rubber at elevated temperatures and resists degradation from synthetic gear oils, a critical advantage in hot climates such as Colombia’s tropical lowland farming regions, where summer ambient temperatures regularly exceed 35\u00b0C.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\"Gearbox<\/p>\n

\n

6. Application Scenarios<\/h2>\n
\n
\n

Vertical TMR Feed Mixer Wagons<\/h3>\n

Total Mixed Ration (TMR) wagons use vertical auger screws to chop, blend, and discharge a precise mixture of forage, silage, concentrates, and supplements. The EP-EG drives the auger at the low output speeds (typically 30\u201380 RPM) required for thorough mixing while handling the high starting torques caused by compacted feed loads. It is compatible with both tractor PTO-driven and electric-motor-driven TMR mixer wagons used widely in the Antioquia and Cundinamarca departments of Colombia.<\/p>\n<\/div>\n

\n

Stationary Feed Mixing Plants<\/h3>\n

Large dairy and beef cattle operations in Colombia often operate stationary mixing towers or batch feed mixing stations where a single high-torque gearbox drives a permanently installed vertical auger. The EP-EG Feed Mixer Planetary Gearbox’s flange-mount configuration and hollow-shaft output option allow direct integration with the auger tube, eliminating intermediate couplings and reducing the total drive-train length \u2014 a valuable benefit in space-constrained machine-room installations.<\/p>\n<\/div>\n

\n

Horizontal Ribbon & Paddle Mixers<\/h3>\n

Although the EP-EG Feed Mixer Planetary Gearbox is optimized for vertical drive configurations, its modular design supports horizontal base-mounted variants for use in ribbon blenders and paddle-type mixing units commonly found in premix feed manufacturing, aquaculture feed preparation, and pet food processing \u2014 industries growing rapidly across Latin America, including Colombia’s expanding aquaculture sector in the Llanos Orientales region.<\/p>\n<\/div>\n

\n

Poultry & Pig Farm Feed Systems<\/h3>\n

Beyond cattle, the EP-EG Series Feed Mixer Planetary Gearbox is widely selected for mechanized feed preparation lines on poultry and swine farms, where accurate, consistent feed blending directly impacts animal growth rates and feed conversion ratios. The gearbox handles the high cyclic loads of hammer-mill-to-mixer transfer conveyors and auger-based batch dosing systems, providing the reliability that modern intensive livestock operations demand in Colombia’s poultry-producing regions around Santander and Valle del Cauca.<\/p>\n<\/div>\n

\n

Replacement & Retrofit for Existing Feed Mixers<\/h3>\n

Many farms and feed equipment distributors in Medell\u00edn, Bogot\u00e1, and Cali are sourcing a reliable replacement planetary gearbox for feed mixer wagons where the original factory gearbox has worn out. The EP-EG Feed Mixer Planetary Gearbox’s multi-option output shaft program and adjustable mounting flange dimensions make it straightforward to adapt to existing mixer frames and auger shaft connections \u2014 reducing machine downtime and avoiding the cost of an entirely new mixer purchase.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\"Gearbox<\/p>\n

\n

7. Regulatory & Legal Framework<\/h2>\n

Procurement and operation of agricultural machinery gearboxes are governed by a combination of domestic regulations and international technical standards. Understanding these frameworks is essential for equipment importers, farm machinery distributors, and OEM manufacturers operating in Colombia and neighboring countries.<\/p>\n

Colombia<\/h3>\n

In Colombia, agricultural machinery and mechanical power transmission equipment are governed by the Instituto Colombiano Agropecuario (ICA)<\/strong> with respect to fitness for agricultural use, and by the Superintendencia de Industria y Comercio (SIC)<\/strong> for product quality and safety conformity. Imported gearboxes must comply with ICONTEC (Instituto Colombiano de Normas T\u00e9cnicas y Certificaci\u00f3n) standards where applicable, particularly the NTC series aligned with ISO quality and safety norms. The national import tariff schedule (Arancel de Aduanas) classifies planetary gearboxes under Chapter 84 of the Harmonized System (HS code 8483.40), subject to the applicable import duty rate and VAT as administered by the DIAN (Direcci\u00f3n de Impuestos y Aduanas Nacionales).<\/p>\n

European Union (CE Marking)<\/h3>\n

The EU Machinery Directive 2006\/42\/EC requires that gearboxes incorporated into agricultural machinery placed on the EU market carry CE marking, demonstrating conformity with essential health and safety requirements. The EP-EG Feed Mixer Planetary Gearbox is designed and documented to support OEM machine builders in obtaining CE certification for their final assembled equipment, including provision of a Declaration of Incorporation as required by Annex II B of the Directive.<\/p>\n

United States \u2014 AGMA & OSHA<\/h3>\n

In North American markets, planetary drive gearboxes used in agricultural machinery must meet design standards issued by the American Gear Manufacturers Association (AGMA), particularly AGMA 2001-D04 and AGMA 6014-A06 for gear durability. OSHA 29 CFR 1910.219 mandates adequate guarding of all rotating power transmission components on machinery accessible to farm workers.<\/p>\n

Brazil \u2014 ABNT & INMETRO<\/h3>\n

Brazil’s Associa\u00e7\u00e3o Brasileira de Normas T\u00e9cnicas (ABNT) publishes technical standards mirroring ISO norms for mechanical drives. The Instituto Nacional de Metrologia (INMETRO) may require conformity assessment for certain agricultural machinery components; importers should confirm current requirements with a certified Brazilian customs agent before shipment.<\/p>\n

General Environmental & Lubricant Disposal<\/h3>\n

Spent gear oil from gearbox maintenance must be collected and disposed of in compliance with local environmental regulations. In Colombia, Decreto 4741 of 2005 classifies used industrial oils as hazardous waste and mandates their management through licensed waste handlers. Farms and distributors in Antioquia, Cundinamarca, and other departments should engage with ICA-registered environmental managers for proper oil collection and recycling.<\/p>\n<\/div>\n

Frequently Asked Questions<\/h2>\n
\nQ1. Which planetary gearbox for feed mixer is best suited for a vertical auger TMR wagon in Colombia with a 6-ton daily feed capacity?<\/summary>\n

For a 6-ton daily TMR vertical auger wagon in Colombian conditions, an EP-Feed Mixer Planetary Gearbox unit rated at 10,000\u201315,000 N\u00b7m output torque with a gear ratio around 1:13.4 is typically appropriate. The exact selection depends on the auger diameter, mixer drum volume, feed type (silage, hay, grain mix ratios), and whether the drive is PTO or electric motor. We recommend submitting your mixer specifications through our technical inquiry form so our engineers can confirm the correct frame size and shaft configuration.<\/p>\n<\/details>\n

\nQ2. How do I get a quote for a feed mixer planetary gearbox for cattle farming in the Antioquia region of Colombia?<\/summary>\n

To receive a prompt and accurate quotation, please provide the required output torque or motor\/PTO power rating, the gear ratio you need, your preferred output shaft type (hollow or solid), and the brand and model of your existing mixer if you are sourcing a replacement. Quotations for standard EP-Feed Mixer Planetary Gearbox units are typically returned within 24 hours on business days. For custom ratios or mounting modifications, allow 48\u201372 hours for engineering review.<\/p>\n<\/details>\n

\nQ3. Can the EP-EG planetary gearbox for feed mixer handle both PTO and electric motor input, and how do I specify the right input option?<\/summary>\n

Yes \u2014 the EP-Feed Mixer Planetary Gearbox Series is compatible with both PTO (power take-off) and electric motor inputs. For PTO drive, specify the input shaft as a splined stub shaft (1-3\/8 in. 6-spline or 1-3\/4 in. 20-spline are the most common for agricultural PTO applications), and pair it with an appropriate wide-angle PTO shaft assembly. For electric motor drive, specify an IEC motor adapter flange on the input housing and provide the motor frame size (such as IEC 160, 180, or 200) along with the shaft diameter; we will supply a coupled motor-gearbox unit ready for installation. Custom PTO-adapter flanges for non-standard motor frames are available on request.<\/p>\n<\/details>\n

\nQ4. How does a used planetary gearbox for feed mixer compare to a new EP-Feed Mixer Planetary Gearbox unit in terms of total cost of ownership?<\/summary>\n

While a used planetary gearbox for a feed mixer may carry a lower initial price, the risk profile is considerably higher: wear on gear flanks and bearing raceways is invisible without complete disassembly and measurement, seals will have degraded, and no warranty protection is available. On a working farm where a gearbox failure during peak feeding season creates immediate animal welfare and operational consequences, the cost of downtime typically exceeds the price premium of a new unit within a single failure event. We recommend new units for production-critical applications and provide a 12-month warranty on all EP-Feed Mixer Planetary Gearbox.<\/p>\n<\/details>\n

\nQ5. What gear oil should I use in an EP-EG vertical feed mixer planetary gearbox operating in Colombia’s tropical climate?<\/summary>\n

We specify ISO VG 220 mineral gear oil (such as Shell Omala S2 G 220, Mobil Gear 600 XP 220, or Castrol Alpha SP 220) as the standard fill for the EP-EG Series. In Colombian tropical lowland locations where ambient temperatures regularly exceed 35\u00b0C, a synthetic ISO VG 220 or 320 gear oil (such as Shell Omala S4 GX 220) is recommended for extended drain intervals and improved thermal stability. Oil level should be checked every 500 operating hours and a complete oil change performed every 2,000 hours or annually, whichever comes first. Always dispose of spent oil through a licensed waste-oil handler in compliance with Colombian Decreto 4741.<\/p>\n<\/details>\n

\nQ6. What maintenance schedule should I follow for a high-torque feed mixer gearbox in a Colombian feedlot with 8+ hours of daily operation?<\/summary>\n

For an EP-EG Feed Mixer Planetary Gearbox running 8\u201312 hours per day in a Colombian feedlot environment, we recommend the following schedule: Daily \u2014 check for oil leaks and listen for unusual noise during the first 15 minutes of operation. Every 500 hours \u2014 inspect and record oil level; check all fasteners for tightness; inspect input and output shaft seals for any sign of weeping. Every 2,000 hours (or annually) \u2014 complete oil drain, flush, and refill with fresh ISO VG 220 gear oil; inspect all mounting bolts; check shaft alignment. Every 5,000 hours (or at 5 years) \u2014 full inspection of planetary carrier bearings and planet pin wear; replace as necessary. Following this schedule maximizes the gearbox’s service life and prevents the catastrophic failures that result from running with degraded lubricant or worn seals.<\/p>\n<\/details>\n

\nQ7. What are the main differences between a TMR mixer planetary gearbox and a standard industrial gear reducer?<\/summary>\n

A TMR mixer planetary gearbox is purpose-designed for vertical auger drive applications with several distinctions from a generic industrial gearbox: it uses a coaxial (vertical) input-output arrangement to suit the auger shaft geometry; it is dimensioned for high peak-torque overloads (2\u20132.5\u00d7 rated) caused by sudden load spikes in packed silage; the housing is sealed to IP65 for outdoor agricultural use; and the output shaft options (spline, hollow) are matched to common mixer OEM interfaces. A general industrial gear reducer may not provide these application-specific features, which is why specifying a dedicated agricultural feed mixer gearbox results in better service life and lower maintenance costs on the farm.<\/p>\n<\/details>\n<\/div>\n
