Working principles and applications

SBM LM series vertical grinding mill is widely applied in metallurgy, construction, chemical and mining industries, being the preferred equipment in grinding industry. It can be used in grinding non-flammable and non-explosive materials with Mohs’ hardness below 9.3, such as grinding quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc.

The design attributes of vertical grinding mill

The vertical grinding mill researched and created by technical gurus of SBM Machinery is dependant on years of analysis on industrial mill, which draws about the fineness grade innovative technology of Germany and Japan, as outlined by the ideas of fluid mechanics, they devoted themselves to establishing the efficient micro powder grinding mill, and fix domestic complications of your large cost of jet mill, resolve ultra-fine powder classification complications. Production and energy consumption are up to the nationwide standard, it ranks the innovative degree and will get a lot of users’ praise.

Vertical grinding mill is mainly composed by the host, blowers, ultra-fine analysis machine, finished cyclone powder collector, bag filter and connecting duct and so on. Based on customers' demand, the site can also be selectively equipped with the hoist, storage silos, control cabinet to the powder machine, crusher and other auxiliary equipment.

It has many advantages as follows:

  • 1. Wide scope, it can grind a variety of materials with less than 6 grade hardness;
  • 2. Under the action of spring, product fineness is greatly improved;
  • 3. Compared with jet mill, the system has low vitality consumption;
  • 4. Less investment, substantial efficiency, quick recovery;
  • 5. Fewer production links, materials with less than 25mm are directly processed by the machine;
  • 6. Pollution-free, dust-removing effect fully meets the state standards;
  • 7.Roller device has good sealing effect.
