Fine CrusherThe system consists of three main components: the main machine, auxiliary machine, and electric control box. It features air classification, no sieve, no screen, and uniform particle size, with a continuous production process. The multifunctional ultra-fine pulverizer has reached international advanced levels and is widely used for material grinding in industries such as pharmaceuticals, chemicals, and food.Fine CrusherThe material is fed into the crushing chamber between the machine body and the guide ring via the spiral feeder at the feed inlet. Inside the crushing chamber, it is impacted by the high-speed rotating blades, causing the fine grinding machine to throw the material against the toothed ring fixed on the machine body. This results in impact, shearing, as well as mutual collision, friction, and shearing between the material, blades, and toothed ring, achieving alternating crushing. The crushed material, under the pulling force of negative pressure airflow, allows small powder particles to overcome their own weight and pass over the guide ring with the airflow, entering the classification chamber. The classification impeller is composed of blades. The high-speed rotating blades generate a centrifugal force opposite to the negative pressure. The powder particles settling into the blade channels are simultaneously subjected to the centripetal force of the negative pressure airflow, their own weight, and the centrifugal force generated by the impeller. Particles larger than the critical diameter (classification particle size) are thrown back into the crushing chamber for further crushing due to their greater mass, while particles smaller than the critical diameter pass through the powder discharge pipe into the cyclone collector and are discharged via the discharge valve. The higher the rotational speed of the classification impeller, the finer the classified powder particles. Adjusting the rotation of the classification impeller is the decisive factor in controlling the particle size.
