As we all know, both the micro powder grinding mill and superfine powder vertical roller mill are the common ultra fine stone powder making machines, however, do you know what’s the difference between them?
Micro Powder Grinding Mill
The micro powder grinding mill can be used in more than 150 kinds of stone materials grinding, and the finish powder fineness could be adjusted between 300 mesh to 2500 mesh. And compare with the superfine powder vertical roller mill, the price of micro powder grinding mill will more cheaper. However, when we use the micro powder grinding mill to process the stone materials, we need set up a sound insulation room, because there is a loud noise when the micro powder grinding mill working, sure it’s just for hard to grind materials.
Superfine Powder Vertical Roller Mill
Compare with micro powder grinding mill, in the same degree of fineness and production, the energy consumption of superfine powder vertical roller mill is less, it’s about 20%-30% of the micro powder grinding mill. And the superfine powder vertical roller mill also has a stronger drying ability
As for the powder fineness made by the superfine powder vertical roller mill is divided into three grades. 600-1250 mesh, 1250-3000 mesh, 3000-10000 mesh, and this requires a corresponding adjustment of the equipment. But it’s more expensive than the micro powder grinding mill, in other words, the money buy one superfine powder vertical roller mill can buy 4 or 5 sets micro powder grinding mill. And the superfine powder vertical roller mill not just has a high fineness powder grinding ability, it also has a large output, the annual output of ultra fine vertical roller mill can up to 50000 tons and even more.
