LM Series Vertical Roller Mill in Cement Industry
Introduction:
LM Series Vertical Cement Mill is mainly used to process cement clinker, sets cement grinding, drying and classifying into one. Its biggest advantage is low power consumption: 24 ~ 27kwh/t. The cement vertical mill from Henan Zhenyuan, compared with its traditional ball mill, can save electricity 30% per ton. Meanwhile, it’s an all-in-one machine, needs less auxiliary equipment, occupies a small footprint, has less dust pollution. It is the new generation of environmental friendly cement grinding equipment in line with national energy saving policy.
Cement Vertical Mill VS Ball Mill, which one is better?
| LM Cement Vertical Mill | VS | Ball Mill |
| Solid structure, small area, strong complete sets, from bulk material to finished powder is one working system. | Structure | Horizontal structure, complete set is not strong, the mutual connection is loose, the single station covers an large area, from the bulk material to finished powder can not be one working system. |
| Grinding and selection can be achieved by one set of equipment, and realized the integration of grinding and selection. | Cost | Grinding and selection should be achieved by two sets of machines and two steps of processes, the invest cost will be increased. |
| The important parts are made of high quality steel, the wear
resistant parts are made of high performance wear resistant material, the whole machine has high wear resistance and running reliability. The wearing parts are long and efficient. | Spare Parts | The lining plate and steel ball are high consumption, the replacement frequency is high,cost is high, and the delay time of production, resulting in unnecessary loss of production. |
| The fineness of the finished powder is uniform, the passing rate can reach 90% or more. | Final Products Size | The fineness of finished powder is uneven, the passing rate is relatively lower. |
| Energy saving and environmental protection, low noise. | Environment | The noise is relatively higher. |
Cement Vertical Mill VS MTW European Grinding Mill, which one is better?
| LM Cement Vertical Mill | VS | MTW European Grinding |
| Simple Structure, and less maintenance | Structure | The rollers are fixed with high pressure, more maintenance cost. |
| Large capacity, can meet large scale demands. | Capacity | Smaller capacity, and can meet the personal investment demands. |
| Because of high efficient reducer, so the shutdown time is less. | Shutdown time of main unit | Longer shutdown time, and some vibrating when stop the machine. |
| Because hydraulic device for roller, so it is easy to maintain and replace the spare parts. | Maintenance | It will spend more time to maintain and replace the spare parts. |
| The lubricating system is oil, good sealing, less fault. | Lubrication System | Grease lubricating system, and can not control the temperature well, so more faults. |
Vertical Cement 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.
