HGM Ultrafine Grinding Mill

Product description in detail

The basic structure consists of the main unit, fan, powder separator, cyclone dust collector, dust collector, pipe device, and motor. The main unit consists of a frame, an air inlet volute, a shovel, a grinding roller, a grinding ring, and a cover. Ancillary equipment also includes jaw crusher, bucket elevator, electromagnetic vibration feeder (small size, can be sealed, can be fed continuously and evenly), silo, power distribution cabinet (control the entire line), etc.

Introduction of working process

This machine can be used to process all kinds of non-flammable and non-explosive mineral materials with Mosh Hardness below 9.3 and humidity below 7%. It is the perfect choice for materials such as quartz, feldspar, calcite, limestone, talc, marble, granite, dolomite, coal, iron ore, and so on. What’s more, the fineness of finished products can be adjusted between 0.18mm and 0.01mm (80 mesh-1250 mesh), and some materials can reach more than 2000 mesh.

After the large block of stone is fully crushed by the crusher, it is evenly fed into the storage bin from the bottom to the top by the bucket elevator, and then sent to the main machine by the vibrating feeder orderly. The material entering the grinding chamber is scooped up by the blade, pressed and crushed between the grinding roller and the ring, and blown into the grinding chamber under the action of the fan, blowing the powder into the analyzer for sorting. The powder that does not meet the fineness requirement is re-dropped into the grinding chamber for processing. The qualified fine powder enters the finished cyclone collector with the airflow, and is separated from the air and discharged from the discharge port to be finished products. The air returns to the fan from the upper return air duct to form a circulating air path, which can flow under negative pressure.
