As the name suggests, AZS420A22 series hammer mill is the diesel driven crushing machine. It mainly consists of three parts on the whole: feed hopper, grinding cell, winding system. After the raw materials were put into crushing chamber, the high-speed operated hammer sheets will impact the raw materials over and over again, then the raw materials will be crushed into pre-set size step-by-step. Materials grinded by the crusher are widely used for wood pellets, wood briquette, wood composite board production.

Key Features of AZS420A22 Wood Hammer Mill

1. With a workhorse of 22HP, a diesel engine can accept a large production work on a daily basis.
2. Both coarse and fine grinding can be realized through adjusting the gap between hammers and screen
3. The rotor of hammer mill operates at 3,500 RPM to produce high hammer tip speed, thus the finished powder can be uniform with the least size.
4. The core part ---the hammers are made of high quality carbon alloy steel, which is durable and wear-resistant.
5. Available screen discharge area can be up to1904 square centimeter which allows for high throughput at a lower horse power.
6. Equipped with air blower, the crushed material can be directly collected and transported to next machine for further processing.
7. You can change screening sieve according to different material grinding requirements.
8. We can customize the following sieve with screening hole diameter of 1.8mm-10mm.

Diesel Wood Hammer Mill Application

crushed materials

It’s commonly used for crushing material at home and farm or in small scale wood processing factories. The raw materials the machine can process are: wood barks, wood cuttings, crop stalks, rice husk, cotton stalks, coconut shells, sunflower husks, wheat straw, rice straw, palm kernel shells, haulm, peanut straw, sweet potato straw and so on. The final products of the hammer mill, fine and uniform, have a wide application for biomass fuel pellets, animal bedding and other wood product production.

Operation Procedures

1. Before start, operator should read this manual carefully to learn about hammer mill structure, performance and operation method.
2. Then, adjust and maintain hammer mill machine on following manual regulations. At the same time check the tightness of fastening parts and make sure each part is lubricated sufficiently.
3. After securing the safety of hammer mill machine and operator, idle the hammer machine for 2-3 minutes on hearing no abnormal sounds. Then feed the raw material.
4. Feed the material in slow and steady way. Overload feeding is forbidden. During material blocking at the entrance keep hands away from the feeding port.
5. Fit the sieve mesh with the machine lower body tight to avoid material leakage to affect the crushing quality.
6. Stop and then inspect the machine if there is any abnormal noise during operation. It is forbidden to inspect hammer machine on running.
7. Keep frequent inspection on hammer blades worn degree and cotter pin condition, and replace the worn parts in time on cutting off the power source. Opening the upper body during running is forbidden.
8. After each shift, idle the machine for 5-10 minutes to suck the material clean and stop the machine. Add lubricating grease to main shaft bearings.

  • What's Application of Pellet Mill?

    Our pellet machine can make animal feed pellets, bedding pellets and home heating pellets. What¡¯s more, you need only one machine to make all these pellets. Widely used in animal husbandry, brewing, sugar, paper factory and other industries of organic waste granulation. The flat die pellet machine is preferred (biological) ideal equipment for organic fertilizer production enterprise.
