What is raymond mill fineness

If you want to know about raymond mill fineness, limestone mill fineness, mineral mill fineness, stone crusher fineness, this article can help you.

Fineness refers to the degree of coarseness or particle size of the material after grinding, for example, the fineness of cement refers to the degree of coarseness and fineness of cement particles. Particle size refers to the size of the sieve holes of the particles passing through the sieve mesh, expressed in mesh is the number of sieve holes of the sieve mesh in the length of 1 inch (25.5㎜).

Raymond mill is used for mineral ore grinding machine, grinding fineness is generally adjustable between 80-425 mesh, part of the material fineness can reach 600 mesh. Raymond mill can grind fineness and the size of the hardness of the ore material also has a relationship. The same fineness, the higher the hardness of the mineral, the lower the powder production. Due to technological development and process improvement, today's Raymond mill can be divided into high-pressure roller mill and European version of the mill, as well as the new R-type Raymond mill. High-pressure roller mill can reach 425 mesh, Europe version of the mill can reach 400 mesh.

What materials can be ground by Raymond mill? Common material hardness from low to high is divided into 10 levels, 1 to 6 levels are listed below:

Level 1: there are talc, montmorillonite, graphite.

Level 2: gypsum, clay, bentonite, weathered stone, etc..

Those of grade 2.5: chlorite, cement clinker

Grade 3: calcite, limestone, marble, dolomite, maficite, copper ore

Grade 3.5: malachite, shell, barite, bauxite, kaolin, china clay, bauxite, zeolite

Grade 4: Fluorite, Magnesite

4.5 grade: bluestone, manganese ore

Grade 5: apatite, phosphate rock

Grade 6: potassium feldspar, feldspar, sodium feldspar, orthoclase, perlite
