What is the crushing process of a half-wet material crusher?

The half-wet material crusher is primarily designed to process materials with high moisture content—specifically those prone to agglomeration and clogging—such as fermented organic fertilizers, livestock and poultry manure, biogas residues, medicinal herb residues, and kitchen waste. Its crushing process is continuous, smooth, and highly resistant to clogging. Materials are fed uniformly into the machine through the inlet, where they first encounter an upper-level loosening mechanism. This mechanism preliminarily breaks apart and loosens any caked or clumped materials, preventing large masses from entering the main crushing chamber directly and causing blockages, thereby preparing the material for subsequent fine crushing. After this pre-loosening stage, the material enters the main crushing chamber. Driven by a high-speed rotating rotor, hammers or blade sets exert powerful impact, shearing, and tearing forces on the material, breaking down large chunks into smaller particles. Simultaneously, the material collides with, is compressed against, and is abraded by the chamber's liner plates and stationary blades, further breaking down fibrous matter and viscous clumps to complete the coarse crushing operation. Under the combined influence of centrifugal force and gravity, the coarsely crushed material moves downward into a secondary crushing zone. Here, it is subjected to a second round of high-speed impact, shearing, and grinding by a denser and more closely arranged array of hammers or blades, further refining the particles until they reach the required fineness. Material that meets the specified fineness criteria is driven by centrifugal force through a sieve screen—or regulated by the clearance between blade discs—and is smoothly discharged through the outlet. Any larger particles that fail to meet the fineness requirements remain within the crushing chamber to undergo further processing until they satisfy the discharge standards. Throughout its operation, the machine leverages a rational structural design and optimized rotor speed to achieve a self-cleaning, anti-clogging effect. This ensures the continuous and stable crushing of even high-moisture materials, producing a uniform particle size that meets the specific requirements for subsequent downstream processes such as granulation, batching, and packaging.
