In the eyes of ordinary people, straw is useless. A few years ago, farmers even burned it to dispose of it. Not only does it waste resources but it also pollutes the air. In the eyes of businessmen, it is a treasure. After harmless fermentation treatment, straw can be processed into high-value organic fertilizer. The same raw materials can also be made include animal manure, edible mushroom residue, household waste, distiller's grains, and so on. The processing of straw into organic fertilizer requires a semi wet material crusher.

The semi wet material crusher has a reasonable structure, convenient installation, and high efficiency, making it the preferred crushing equipment for crushing high humidity, multi fiber raw materials. This machine is a new type of high-efficiency single rotor reversible crusher, which utilizes high-speed rotating blades to crush fibers with good particle size and strong adaptability to material moisture content. It can be used for pulverizing fermented decomposed garbage or other materials with high moisture content, and has high efficiency and energy efficiency, meeting the feed particle size requirements of general fertilizer granulation equipment. The semi wet material grinder is mostly used in the production and processing of organic fertilizer. The applicable materials include plant straw, weeds, fermented livestock manure, domestic garbage, food residue, biogas residue, etc. The semi wet material crusher helps to shorten the process flow, reduce equipment investment, and save operating costs in organic fertilizer and compost production. It is an ideal equipment for fertilizer production and processing enterprises.

The working principle of a semi wet material crusher:

1. The equipment adopts a two-stage rotor for upper and lower crushing. When the material passes through the upper rotor, it is crushed into small particles, which are then transported to the lower rotor for crushing to a qualified state and discharged from the discharge port.

2. The equipment adopts a mesh free design, and various materials can be crushed. There will be no blockage during the crushing process, and there is no problem of fine powder not being discharged in a timely manner or being repeatedly crushed.

3. The equipment adopts a high alloy wear-resistant hammer head, and the hammer piece is made by forging, which is very sturdy and wear-resistant, increasing the service life of the hammer piece.

4. The equipment adopts bidirectional gap adjustment technology, and after the hammer is worn, it does not need to be repaired. Moving the position of the hammer can continue to use, and adjusting the gap between the hammer head and the lining plate can control the material particle size.

5. The equipment adopts high-tech technology, which can be easily operated by just one person. It is not only safe and reliable, but also easy to maintain.

6. The equipment is equipped with a centralized lubrication system for oil injection. Under normal operation, lubricating oil can be injected without the need for shutdown.
