Granulators GM-150 and GM-180 are intended to be the parts of small feed-stuff factories. Vee-belt drive is used in their construction. The advantages of vee-belt drive are simple construction and longevity. The flywheel of granulator has big weight and diameter. Because of that inertia smooths the work of granulator. The consequence of this fact is a decrease of burden on the motor and bearings. Moreover, there are no high-wear details, there is no requirement for usage of expensive lubricating compositions.
Why many other producers of granulators don't use the flywheel and state that reducer is better? Because they can't manufacture the flywheel, they don't have foundry engineering and other equipment. Meanwhile the usage of reducer leads to frequent expensive breakages and rapid changings of reducers.

Highly-productive granulators GM-250, GM-280 and 4-roller granulator GM-280М are intended to be the parts of big farms and feed-stuff factories. Massive cast-iron flywheel with V-belt drive plays a role of a compensator of fluctuating loads and makes additional inertial power. It makes process of granulator's motor work easier. An angle countershaft is replaced by vee-belt drive which leads to absence of unreliable details. This construction is much better than any reducer because of its' reliability. Reducer resists radial load but it's not successful at resisting axle load. That's the principle of reducer's system.
Granulators can be used in manufacturing of grass meal or brewer pellet.

Hay cutter is used for grinding of hay or wood sawdust.
Grass meal producing line consists of hay cutter and cyclone collector.

Roller grain crusher is intended to be used for crushing whole grains and big granules. Flattening machine can be used for flattening of grain.

Batcher provides a granulator with uninterrupted supply of raw materials. Optimal pace of supply can be set. Complex of granulator and batcher-mixer or a couple of batchers creates a permanent production of mixed fodder.
