Working part for a 150 mm granulator (GKM/OGP/Rotex)

Working unit for 150 mm granulator (GKM/OGP/Rotex) is the key pressing assembly for creating or upgrading a medium-productivity feed pellet granulator. Manufactured by Ukrainian plant TechnoMashStroy, this working unit allows you to assemble your own granulator if you have a motor, pulleys, and frame, or replace a worn unit in existing equipment.

Purpose and Compatibility

This working unit is designed for GKM-150, OGP-150, and Rotex-150 granulator models. It is an ideal solution for those who want to save money by having the necessary components (electric motor, pulleys, frame) and wish to purchase only the main pressing module.

The equipment is suitable for use in medium-sized farms, poultry facilities, rabbitries, and fish farms for producing pelleted feed for cattle, pigs, sheep, goats, rabbits, poultry, and fish.

Design Features

The working unit includes the granulator head with a raw material hopper and a tray for finished product output. The double-sided 150 mm diameter die provides a long service life — after one side wears out, it can be flipped to continue operation.

The rollers are made of high-quality hardened 40Kh steel, ensuring resistance to abrasive wear when working with various types of raw materials. Roller mounting is carried out using special tension bolts, simplifying adjustment and replacement.

The extended hopper facilitates raw material loading and improves operational convenience. For an additional fee, a loading conveyor can be installed to automate material feeding.

Advantages

• Cost savings — ability to assemble a granulator yourself from available components
• Versatility — suitable for GKM-150, OGP-150, and Rotex-150 models
• Double-sided die — extended service life
• High material quality — hardened 40Kh steel
• Simple construction — easy maintenance and replacement of worn parts
• Ukrainian manufacturing — affordable spare parts and service
• Optimal productivity — ideal for medium-sized farms
• Conveyor installation option — automated material feeding

Raw Materials for Granulation

The GKM-150/OGP-150/Rotex-150 working unit works efficiently with grain mixtures, bran, oilcake, meal, grass meal, compound feed for various types of animals and poultry, as well as sawdust, straw, and hay for producing fuel pellets. The optimal moisture content for granulation is 10-15%.

Depending on the selected die (2, 3, 4, 5, 6, or 8 mm), you can produce pellets of different diameters, adapted to the needs of specific animals: small pellets for poultry and rabbits, medium ones for pigs and sheep, larger ones for cattle.

Package Contents

The working unit comes with a hopper, finished product tray, double-sided die (hole diameter optional), two rollers, and a cutting knife. For an additional fee, you can purchase a pulley set for transmitting rotational torque from the motor or a loading conveyor.

This is a reliable and affordable solution for those who want to organize their own production of pelleted feed for medium-sized farms or small businesses producing compound feed and fuel pellets.
