HGM ultrafine mill

HGM series grinding mill also called HGM ultrafine mill, HGM ultrafine grinding mill, and HGM micro powder grinding mill. It consists of multiple grinding rollers(21/24/28/32 pieces) and multi-layer grinding rings(3/4 layers).

HGM series grinding mill can process a variety of stones with Mohs hardness below 6, such as limestone, dolomite, barite, gypsum, etc. Of course, it also includes bluestone, white stone, black stone, red stone, and yellow stone.

Due to its multi-layer grinding structure design, the mill can process ultra-fine powder efficiently. The maximum fineness can reach 3000 mesh.

You can produce stone powder ranging from 150 mesh to 3000 mesh by adjusting the speed of the classifier.

HGM series grinding mill has 5 models: HGM80, HGM90, HGM100, HGM125, and HGM1680.

Different models can process different outputs, and the larger the model, the greater the output.

Just send us the material you want to process, the output size, and the hourly output and we will send you an instant quote.

What is Mohs hardness and How hard is Mohs hardness 6?

Mohs hardness is graded by measuring the depth of a scratch, with 10 being the highest hardness: diamond, and 1 being the lowest hardness: talc.

Mohs hardness 6 is equivalent to orthoclase.
