Different then our basic pneumatic roller mill, the incoming product level is measured by a sensor or a loadcell. The feed roll speed varies according to incoming flow rate and homogeneous flow is achieved. In the meantime, the gap between the rolls is reduced by pneumatic pistons and the product is grinded by passing between the rolls. The bushings of the roller mills are spheroid casting and the rolls have conical arms. Both belt driven and gear driven machines are available. As an option, they are also produced with a touch screen control panel.
