HGM ultrafine powder mill​

The grinding mill production line usually includes a hammer crusher, bucket elevator, storage bin, vibrating feeder, micro-powder mill host, frequency conversion classifier, double cyclone powder collector, pulse dust removal system, high-pressure fan, and air compressor , electrical control system and other components. The large pieces of material are crushed by the hammer crusher into a feed particle size suitable for the operation of the ultra-fine mill (about 1cm), and then the speed of the mill analyzer is adjusted to achieve a fineness suitable for production requirements, and are manually packaged into bags. , you can also configure an automatic micro-powder baler and choose different types of grinders as needed.

  • Product Features : When the finished product fineness and motor power are the same. The output of SCM ultrafine mill is 40% higher than that of air flow mill and stirring mill, and more than double that of ball mill. Its system energy consumption is only one-third of that of airflow mills.
  • Input Size : <20mm
    Capacity : 0.5-12 TPH
    Material : limestone, sedimentary rock, metamorphic rock

Product Details

Working principle of ultrafine grinding mill:
When working, the main motor drives the main shaft and the turntable to rotate through the reducer, and the roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the grinding ring raceway. The large materials are broken into small particles by the hammer crusher, and then sent to the storage bin by the elevator. Then, the materials are evenly sent to the bulk plate on the upper part of the turntable through the vibrating feeder and inclined feeding pipe. The materials will be scattered toward the edge of circle under the action of centrifugal force and fall into the ring, where they will be impacted, rolled and grinded by the rollers. After being processed by the three-layer ring, the material will become powder. The high-pressure blower will suck the outside air It is sucked into the machine and the crushed materials are brought into the powder separator. The rotating impeller in the powder concentrator makes the coarse materials return to the grinding machine for regrinding. The fine powder that meets the requirements will enter the cyclone powder collector with the air flow and be discharged from the discharge valve at the bottom as the finished product. The air flow with a small amount of fine dust will pass through After the pulse dust collector, it is discharged through a fan and a muffler.

High Output and Low Energy Consumption

Under the same finished product fineness and electromotor power, the capacity of SCM ultrafine pulverizer is 40% higher than that of a jet mill or astirred mill and doubles the capacity of a ball mill while its system energy consumption is only one-third of jet mill.

High Fineness

Product fineness can be arbitrary adjusted within a range from 325 to 2500 meshes and its disposable fineness can reach D97≤5um.

 

 

Heavy rotor design and tight test method

The application of the pulsed jet filter and silencer has reduced the dust pollution and the noise at the construction site is very low in accordance with state standards.

 

 

Safe and Reliable

Grinding rollers and rings are forged by special materials and their service life is 2 to 5 times longer than the wearout parts of the impulse-type breaker and the turbine type pulverizer. Generally it can use over one year and even up to 2-5 years for processing calcium carbonate and calcite.
