Description CHOPPER-800 Hammer Mill for PTO

The CHOPPER-800 hammer mill for PTO is an efficient and versatile machine designed for grinding wood chips, grains, and other bulk materials. The tractor power take-off (PTO) drive allows the machine to operate without access to the electrical grid, making it an excellent solution for farms, wood processing facilities, and field applications.

The CHOPPER-800 is mounted on the tractor’s three-point hitch and driven by a reliable belt transmission. This solution ensures stable operation and reduces the load on individual machine components.

Operating principle

The CHOPPER-800 offers two methods of material feeding. Raw material can be loaded directly through the hopper, which is particularly suitable for grain processing, or automatically drawn in using the pneumatic system.

With pneumatic intake, the material is drawn through a flexible hose with a diameter of 127 mm and transported to the grinding chamber by a powerful airflow. This enables efficient feeding of wood chips and lightweight materials without the need for additional conveyors.

Grinding takes place in the working chamber by means of a high-speed rotor equipped with hammers. The material is repeatedly struck and then passes through a replaceable screen, which determines the required final particle size.

After grinding, the material is transported together with the airflow to the cyclone, where the finished product is separated from the air. This solution reduces dust at the workplace and makes collection of the processed material easier.

Key advantages

• Tractor PTO drive – operation without access to electrical power;

• Capacity of up to 800 kg/h for wood chips;

• High grain processing capacity – up to 2,500 kg/h for wheat and corn;

• Two material feeding methods – hopper feed or pneumatic intake;

• Hammer grinding system – effective and uniform size reduction;

• Replaceable screens – final particle size can be adapted to the application;

• Pneumatic system with cyclone – efficient material transport and reduced dust;

• Robust construction – designed for use on farms and in production facilities;

• Mobility – the machine can be used at different work locations.

Applications

The CHOPPER-800 is designed for grinding wood chips, wheat, corn, and other bulk and plant-based materials.

The processed material can be used, among other applications, for the production of pellets, briquettes, animal feed, and other products requiring proper raw-material preparation.

The machine is suitable for farms, biomass processing facilities, sawmills, and wood-processing companies.

Capacity

• Wood chips: up to 800 kg/h (pneumatic intake, 6 mm screen)

• Wheat: up to 2,500 kg/h (pneumatic intake, 3 mm screen)

• Corn: up to 2,500 kg/h (pneumatic intake, 6 mm screen)

• Corn: up to 6,000 kg/h (hopper feed, 6 mm screen)

Actual capacity depends, among other factors, on the moisture content and properties of the raw material, the screen used, and the tractor power.
