Vertical Roller Grinding Mill

Product Specification

LM Series Vertical Roller Grinding Mill

Introduction:

LM Series Vertical Roller Mill has combined the advanced Loesche technology introduced in German, MPS technique with innovative upgrading of our R&D team. For its low cost in operating, high quality of finished product, easy operation and easy maintenance, energy saving and environmental protection, LM series vertical mill is widely used in metallurgy, electric power, cement ash, flue gas desulphurization and waste utilization, and it also has predominance in the fields of non-metallic minerals, coal and slag.

Advantage:

• Low cost for investment: Integrating grinding, drying, grading and delivering. Simple structure, compact layout and open layout can significantly reduce the costs
• Advanced transmission system brings high bearing capacity: New structure of gear reducer makes the machine a greater carrying capacity
• Hydraulic device makes maintenance more convenient: the most advanced hydraulic control system changes pressure automatically according to the materials, keeping it in the best condition, which reduces energy consumption and prolong the lifespan of roller sleeve and liner
• Reliable thin oil lubrication: the most advanced independent lubrication station, automatic protection system makes it safe and reliable in operation
• Applicable and multiple classifiers: Frequency control of separator is according to the different kind of materials and fineness. Particle size is in uniformity and easier for adjustment
• Electronic control system is of high automation: equipped with advanced electronic control system enable PLC, DCS and centralized control and meet multiple needs
• Energy saving and sustainable: less noise when working; after dust emission of the finished products, the dust density is much lower than the government standard on environmental protection

Vertical Roller Mill Working Principle:

Full set of vertical mill consists of: main unit, bucket elevator, adjustable hopper, sealed constant feeder, air heating furnace, dust remover, blower and silencer.

The motor drives the grinding table to rotate by reducer, and the hot air goes into the inner part of machine at the same time. The materials fall down to the center of grinding table from feed opening. Driven by the centrifugal force, materials move evenly to the edge of the grinding table, and they are grinded by the rollers when going through the rollers’ track. Bulk materials are crushed, while fine materials form material bed after being squeezed and experience intergranular crushing. Grinded materials move on to edge of the grinding table until being taken away by strong airflow at the wind ring, in which larger materials fall to the grinding table by gravity and reground. The others enter the separator being graded. Under the influence of separator blades, materials that do not meet fineness requirements return to the grinding table to be grinded, while the standard ones go into dust collector through the pipes and are discharged as finished products from the discharge device. Irons and other impurities, which cannot be lifted by the wind for weight, move together with materials to the edge of grinding table and fall to the lower cavity, and then they are scraped i1 Setnto the slag discharge opening by stripper plate which is fixed at the bottom of the grinding plate and discharged out of the machine.
