LM Vertical Grinding Mill
More stable and reliable production and more excellent capacity
The LM Vertical Grinding Mill, launched by ZENITH, integrates five functions of crushing, grinding, powder selection, drying and material conveying. It is characterized by centralized technological process, small occupational area, low investment, high efficiency, energy conservation and environment protection. It is the ideal equipment in the grinding industry.
Material: Limestone, calcite, dolomite, petroleum coal, gypsum, barite, marble, talc, coal powder, etc.
LM Vertical Grinding Mill achieves lower energy consumption, stronger drying capacity, as well as lower abrasion and easier checks of core parts, saving operating costs greatly.
Materials linger in the grinding mill for a short time, which can reduce repeated grinding and is easy to detect and control the grain size and chemical component of the product.
The system is sealed in an integral manner and works under negative pressure, so that there is no dust spilling and the environment can keep clean.
Its occupational area is about 50% of that of the ball-milling system. The LM grinding mill can also be arranged outdoors, which greatly reduces the investment cost.
Working Principle of LM Vertical Grinding Mill
After raw materials fall onto the center of grinding plate, large materials are broken directly. For coarse materials which cannot be brought away would fall onto the grinding plate for another grinding. When passing the upper separator, materials in the airflow will be divided into two parts by the blades of rotor, that is, coarse particles and fine powders. Coarse particles would be sent back to have another grinding while qualified fine powders enter the powder collector with airflow as finished products. For sundries like iron block in materials, they would drop to the lower cavity of grinding mill and next be sent into the discharging port and finally be discharged out of the grinding mill.
