Second hand universal crusher, ultra-fine airflow mill, multifunctional grinding machine

No complex hydraulic or pneumatic systems, smooth operation, relatively low noise (<85 decibels); The gear and screen are made of high hardness stainless steel or wear-resistant alloy, which has slow wear and low maintenance costs. Hygiene grade design, easy to clean: all stainless steel structure, polished inner wall without powder accumulation, front cover can be quickly opened, screen mesh and gear plate can be quickly disassembled for easy cleaning and material replacement, in compliance with pharmaceutical and food GMP standards. Comes with air cooling, optional water cooling: high-speed rotation will generate airflow, taking away some heat; Optional water-cooled jacket or water-cooled bearing seat can be used to reduce the temperature inside the machine, suitable for slightly heat sensitive materials (such as materials with slightly high sugar and oil content)

The material enters the center of the crushing chamber from the feeding hopper and is instantly thrown towards the surrounding wall by the centrifugal force generated by the high-speed rotating movable toothed disc. Between the moving and stationary gears, the material is crushed by high-speed impact, shearing, grinding of steel teeth, as well as intense collisions between particles. The crushed material reaches the annular space on the outer wall of the turntable, and fine particles pass through the sieve holes of the annular screen and are discharged from the bottom outlet under the action of gravity or negative pressure airflow; Coarse particles remain in the sieve and continue to be hit and ground by the toothed disc until the fineness meets the standard and passes through the sieve. This closed-loop cycle of "crushing screening coarse material reflux and further crushing" continues until all materials reach the set fineness.

Widely applicable and versatile: it can handle various dry and brittle materials with low to medium hardness (Mohs hardness ≤ 9), low viscosity, and non heat sensitive properties, such as Chinese herbs (roots, stems, leaves), grains, spices, white sugar, salt, chemical raw materials (pigments, resins, additives), plastics, rubber, minerals (1-5mm), etc. Adjustable particle size and flexible control: Simply replace the sieve with different aperture sizes to flexibly adjust the discharge fineness within the range of 10-120 mesh (approximately 0.125mm~2mm), meeting the requirements of different processes for coarse and medium powders. Simple structure, sturdy and durable: no complex hydraulic or pneumatic systems, smooth operation, relatively low noise (<85 decibels); The gear and screen are made of high hardness stainless steel or wear-resistant alloy, which has slow wear and low maintenance costs.
