D&Q Mining is a high-tech company integrating R&D, production and sales. It provides mature products and solutions such as crushers, sand making, milling equipment, mobile crushing stations, etc., for aggregate, mining and waste recycling.

Our ball mills include monitoring systems to continuously measure the material and air temperatures as well as the pressure at the mill exit. The venting of the mill is adjusted by a damper in the inlet to the mill fan. And the material fill level is continuously monitored by means of sensors. For ball mills operating in closed circuit, the
