Non-metallic ore production line is a non-metallic ore processing production line mainly for processing gypsum, calcite, quartzite and bauxite. The fineness of finished products varies from 325 mesh to 1250 mesh, which puts forward extremely high requirements for the granularity adjustment ability of finished products.

Because it involves the deep processing of various non-metallic minerals, including ultra-fine grinding, fine powder classification, fine purification and surface modification, the engineers of Dawn Heavy Industry chose the TGM130 overpressure trapezoidal mill with a rated power of 157.5KW as the core equipment of the whole production line. This equipment performs well in both classification and purification adopts a high-density and high-precision impeller device. Compared with traditional equipment, the powder separation efficiency can be increased by more than 50 % under the same power. Two installed in parallel, stable operation, simple operation, no failure problems, customer feedback is good.

The TGM series trapezoidal mill is widely used in the field of building gypsum calcination grinding powder. It is widely welcomed because of its simple and compact structure, small footprint and strong production capacity.
