What is the grinding mill for 400 mesh-2500 mesh ultra-fine fly ash?

The general coarse ash and fly ash processing equipment processes the coarse ash and fly ash to a diameter of 32μm. Grinding mill equipment with fineness below 400 mesh. It can increase the value of coarse ash and fly ash ten times. What are the specific coarse ash and fly ash grinding mill equipment?

(1) GKH series ultrafine mill

GKH series ultra-fine ring roller mill has been pursued by the majority of customers because of its energy saving, consumption reduction, economy and practicality. GKH series ultra-fine ring roller mill adopts the grinding roller installed on the rotary table in the main engine cavity to rotate around the central axis, and there is a large movable gap between the grinding roller and the grinding roller pin. Under the action of centrifugal force, the grinding roller swings horizontally outward, so that the grinding roller presses the grinding ring, and the grinding roller rotates around the grinding roller pin at the same time. The material passes through the gap between the grinding roller and the grinding ring to achieve crushing and grinding due to the rolling of the grinding roller. The grinding roller is divided into 4 layers , and the material passes through the first layer of grinding roller and the grinding ring for one-time crushing. Then it passes through the second, third and fourth layers for secondary, third and fourth crushing. Therefore, the material is fully ground and the particle size of the finished product is 5-45 μ m。

Whether the primary ash or secondary ash is produced by ring roller mill, the powder produced is very uniform and almost has no quality problems. It is the best choice for coarse ash and fly ash processing equipment.

（2）GKLMX series superfine vertical grinding mill

GKLMX series super-fine vertical grinding mill, as the product of coarse ash and fly ash processing equipment, draws lessons from the technology of Germany, Japan and Taiwan. Based on GKLM Vertical roller mill, it has been reasonably developed according to local conditions. Now it is the preferred product of large-scale coarse ash and fly ash processing equipment in China. GKLMX series superfine vertical grinding mill have the advantages of strong material adaptability, continuous production, stable operation, high efficiency, simple process flow, small floor area, easy adjustment of product fineness, low noise and less dust.
