working principle of Straight Centrifugal Grinder

While working, motor drives the hanger of grinding roller to rotate through V pulley and centre bearing. Roller which is hung by bearing and pendulum shaft will roll along the inner circle of roll ring while the hanger is rotating. Dust removal blower will generate negative pressure at the inlet and outlet of the grinder to prevent dust and radiating the heat in the machine.

benefits of Straight Centrifugal Grinder

Straight centrifugal grinder is kind of latest grinder designed and manufactured by experts from Shanghai Shibang Machinery Co., Ltd on the basis of long-term production and application. It is possessed of leading technology and starts a new era of industrial grinder of low energy consumption. ZTM straight centrifugal grinder is designed and manufactured to solve the problem of high-energy consumption of industrial grinders.
In order to achieve the goal, we have organized accomplished experts of our company who have succeeded in designing and manufacturing grinder of low energy consumption after years’ painstaking. Centrifugal grinder is a kind of effective grinder that be applied in a wide range.

application of Straight Centrifugal Grinder:

This kind of vertical mill is used to grind the barite, limestone, kaolin, ceramics, and slag, etc, below scale 9.5 of Mohs hardness and 280 odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgical industrial, chemical engineering and building material for high fine powder generation and processing. The product size is adjustable in the range of 0-2.8mm.
