• Soft materials: calcite, marble, limestone, kaoline, gesso, barite, coal ash and slag, etc.
• Hard materials: carborundum, brown corundum, superfine cement, zirconium sand, and fire-proof materials, etc.
• High purity materials: quartz, feldspar, α-alumina, glass fine bead, etc.
• Metal powders: zinc powder, aluminum powder, iron powder, and molybdenum powder, etc.

• Low energy consumption: our LHM superfine ball mill production line adopted high advanced energy-saving technology and classification technique; as a result, our production line can save over 40% energy for producing same quantity materials.
• Several times of classification could be obtained:
  Finished product fineness after first time classification: 300-2500mesh; if our ball mill production line is equipped with a second classification system, the finished product fineness after second time classification would be 6,250mesh (d97≤2um).
• Adopted highly advanced self-diffluent classification system:
  
  (1) The classifiers in LHM ball mill production line have a precise classification, so the produced materials have uniform fineness;
  (2) High classification capacity: 100t/h;
  (3) Low energy consumption: For classifying the same quantity of raw materials, a classifier in LHM ball mill production line can save about 40% energy comparing with traditional ball mills.
  (4) High classification efficiency (50% higher than classifiers in traditional grinding mills)
• Scientific grinding medium enable us to produce large quantity superfine particles.
• Different lining boards and grinding mediums are available for milling different materials, so as to guarantee the purity and whiteness of finished products.
• Scientific machine structure enables a lower investment cost;
• Low failure rate and stale operation: because our ball mills and classifiers in the production lines are VFC controlled and have high automation;
• Negative pressure production condition gives a good production environment;
• High annual production capacity: 5-500 thousand tons.

Note: We have prepared two sets of ball mill production lines in our factory to do any industrial testing!

• Material feeding: After the materials are roughly crushed, they will be fed into the ball mills.
• Impact grinding: when the milling chamber is rotating at high speed, grinding medium and grind-need materials, which are also rotating, will impact with each other; thus to achieve impact grinding for materials;
• Classification: after the materials are crushed, they will be discharged into self-diffluent classifiers. And then the relatively coarse and fine powders will be separated. Qualified powders will be collected; and unqualified powders will be re-crushed.

Note: Cleaned gas will be discharged by induced draft fans.
