The high-efficiency pin-type grinding structure is suitable for continuous and cyclic production of nano-scale grinding with a large flow rate. Production efficiency can be increased by 30~50% after being integrated into the production line. It is widely used in nano new materials, magnetic materials, electronic ceramics, ceramic inks, lithium iron phosphate, alumina, and other industries. The newly upgraded, more accurate and stable operating system is adopted, where the flow rate can be set on the PLC, and a new safety production protection function is added.
