Cement row mill rotary airlock valve

1. Introduction：

The bimetallic  overlay wear resistant  plate for rotary feed sluice  for vertical mill is a special rotary Gas-Lock Valve is designed on the basis of quantitative rotary airlock vane feeder valve, that adapt to the Large block material of gas block process system for high temperature.The rotary airlock vane feeder valve is applied to the preparation system for pulverized coal and raw material grinding of 2500~5000t/d production line.

This rotary airlock vane feeder valve is no more than used for rotary feeding, but also has the fuction of block high temperature gas. The structure of rotary airlock vane feeder valve body is compact, and the maintenance is convenient. The inter space between the stator and the rotor is adjustable, and its primary parts are made with low carbon alloy steel which is characterized with heat-resistant. The pressed gas insufflate into the center of the rotor discontinuously, it can clean up the clay material effectually which is adhered on the core of clique and improve the clique work conditions greatly, which can largely increase the work condition of the rotary airlock vane feeder valve, and the ability of impact-resistance. The motor of the rotary airlock vane feeder valve is the direct-connection typed motor, which can deploy soft starter control and stable motility.
