The npk production line mainly includes feeder, disc mixer, chain crusher, drum granulator, drum dryer, drum cooler, drum screener, finished product warehouse, automatic packaging machine, belt conveyor machine, dust settling chamber, heat exchanger.
Chain crusher is an important equipment for npk fertilizer production line. It is suitable for agglomerate crushing in the production of organic fertilizer and compound fertilizer. It is also widely used in chemical industry, building materials, mining and other industries. High-strength wear-resistant carbide chain plates with synchronous speed are used in the crushing process. The design of the inlet and outlet is reasonable, the crushed materials are uniform, not easy to stick to the wall, and easy to clean. high. Chain crushers are divided into vertical and horizontal chain crushers according to the installation form. Vertical chain crusher is single rotor, horizontal chain crusher is double rotor with steel chain. One end of the chain is connected to the rotor, and the other end of the chain is equipped with a ring head made of wear-resistant steel.
Matters needing attention in the use of organic fertilizer crusher:
1. Before using the shredder, it is necessary to check whether the shape of the machine is damaged due to transportation, and whether the random data is complete. Before turning on the power, please ensure that there is iron foreign matter in the cavity to prevent the knife from turning, and manually turn the flywheel several times.
2. If there is wear, please cut the knife in time. When installing the tool, the rotary knife must be tightened. The fixed knife only needs to be fixed a little, adjust the 4-head knife adjusting screw to ensure that the rotary knife and the fixed knife maintain a gap of 0, 2-0, 3, then tighten the fixed knife screw and lock the adjusting screw to complete the tool installation.
3. In the npk fertilizer manufacturing process, the mill runs for about 500 hours, please check the left and right main bearings, clean if necessary, add appropriate amount of grease or replace all grease, organic fertilizer grinding machine equipment to the allowable moisture content of biological fermentation organic fertilizer materials 25-55 %, the crushing particle size meets the requirements of 50 mesh granulation.
