Shanghai resumed work and production on June 1st. The shipment was arranged on the first day. HGM80 21 roller grinding mill will be sent to Pakistan.
The 21 roller mill will be used in the production of calcium carbonate. This Pakistani customer's raw materials are limestone, calcite, and dolomite.
The discharging fineness is 600 mesh to 800 mesh. The output is 3 tons per hour.


What is 21 roller mill?

21 roller mill also called HGM80 ultrafine grinding mill. In Pakistan, 21 roller mill is better known.

HGM ultra-fine grinding mill is a kind of ultra-fine pulverizing equipment developed and produced by Shanghai CLIRIK for processing non-metallic ores.
In fact, there are 7 models of HGM series ultra-fine grinding mill: HGM80, HGM80A, HGM90L, HGM100L-Ⅱ, HGM100P,  HGM125L, HGM1680L.

Application scope of 21 roller mill

HGM Ultrafine Grinding Mill mainly apply to the non-inflammable, non-explosive and brittle materials with Moh's hardness under 6, such as limestone, marble, calcite, chalk, limestone, dolomite, gypsum, kaolin, talc, mica, feldspar totally more than 100 kinds of materials.

The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm.

Working principle of 21 roller mill

  • 1. Large pieces of material are crushed to the required size by the jaw crusher.
  • 2. Crushed material is sent to the storage hopper by elevator.
  • 3. Vibrating feeder send material to the main grinding chamber evenly and continuously for grinding.
  • 4. The ground powder is taken away by the airflow of the fan and classified by the analyzer.
  • 5. The finished product that meets the fineness is collected by the airflow through the pipe, then into the large selection air collecting pipe.
  • 6. The material is discharged through the powder outlet pipe to become the finished powder.
