A semi wet material crusher is a specialized equipment used in organic fertilizer production lines to crush organic materials containing a certain amount of moisture, especially suitable for processing livestock and poultry manure such as pig manure, cow manure, chicken manure, and partially wet biomass raw materials. Its uniqueness lies in its ability to effectively crush organic materials without completely drying them, which is crucial for maintaining their biological activity and nutritional value. Below is a detailed introduction to the working principle of the semi wet material crusher:
working principle
The semi wet material crusher usually adopts the design concept of hammer or blade, and its core technology lies in the high-speed rotating striking element (hammer or blade) cooperating with the lining plate or screen fixed inside the machine to complete the material crushing operation together.
Feeding and Pre dispersion: Organic materials enter the crusher chamber through the feeding port, and are quickly pushed towards the surrounding stator or lining plate by the high-speed rotating rotor.
Impact and Shear: The hammerhead or blade on the rotor impacts the material at extremely high speeds, generating strong impact force that breaks the material. At the same time, the narrow gap between the edge of the hammer and the stator will generate shear effects, further refining the material particles.
Screening and discharge: The crushed material will continue to be pushed by the hammer head and pass through the screen set at the bottom or side of the machine. The size of the sieve determines the particle size of the final crushed product. Only particles that meet the size requirements can be discharged through the sieve, while larger particles will be sent back to the crushing zone until the set crushing effect is achieved.
Characteristics and advantages
Strong adaptability: capable of handling materials with a moisture content of up to 50%, without clogging or reducing crushing efficiency due to material moisture.
Efficient and energy-saving: The unique structural design results in a higher energy utilization rate during the crushing process, saving energy consumption compared to the traditional method of drying and then crushing.
Easy maintenance: Due to the use of wear-resistant materials for the hammer head and screen, the wear rate is low, the replacement cycle is long, and the daily maintenance and operation costs are reduced.
Widely applicable: Not only can it be used in organic fertilizer production, but it can also handle wet material crushing needs in various fields such as biomass fuel and feed processing.
In short, the semi wet material crusher plays an indispensable role in organic fertilizer production lines with its unique design concept and efficient performance, greatly improving the efficiency and quality of organic material processing and promoting the development of organic agriculture.
