Note:

1.The bulk specific weight is calculated by 1.6t/m³. When the width of the feeding port is above 600mm, it is a large-scale machine while when the width ranges from 300 to 600mm, it is a medium-sized machine.

Performance

 

Less Comprehensive Investment

Vertical Grinding Mill integrates crushing, drying, grinding, separating and transport. The structure is simple while the layout is compact. 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.

 

Comprehensive Optimization, Lower Operating Costs

From aspects of grinding efficiency, powder drying, abrasion of vulnerable parts and maintenance & replacement of spare parts, SBM’s LM Vertical Grinding Mill achieves lower energy consumption, stronger drying capacity, as well as lower abrasion and easier checks of core parts, saving the operating costs greatly.

 

Short Grinding Time & Low Iron Content

The 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. In addition, the grinding roller and millstone do not contact directly. The iron content in the product is very low, and the iron generated due to mechanical wear is easy to be removed, thus effectively guaranteeing the whiteness and purity of the material.

 

Greener & More Automated

The operation of LM grinding mill is stable and has small vibration, so that the noise is small. 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 with the emission standard far better than the international standard. LM grinding mill is also equipped with expert-level automatic control system, which can realize free switch between remote control and local control. The operations are simple and labor-saving.

 

Digitalized Processing, Higher Precision

There are tens of lines of numerical controlling machine tools. Operations such as steel plates’ cutting, bending, planing, milling and paint spraying are all controlled numerically. The machining precision is high, especially for the core parts.

 

Sufficient Supply Of Spare Parts, Worry-Free Operation

SBM, whose businesses cover production and sales, takes responsibility for every machine produced by ourselves. We can offer customers technical services about products and original spare parts to ensure the worry-free operation.

Working Principle

The grinding plate rotates under the action of main motor of  Vertical Grinding Mill and the reducer. Meanwhile, hot wind enters the vertical mill. After raw materials fall onto the center of grinding plate, they move to the edge of grinding plate under the action of centrifugal force. While passing through the grinding area between roller and grinding plate, bulky materials are broken directly by the pressure of roller while fine materials form a layer where materials crush each other. Broken materials after grinding continue moving to the edge of grinding plate until they are brought away by the airflow at the air ring. 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 air flow 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 the qualified fine powders enter the powder collector with airflow as finished products. For sundries like iron block in materials, when they move to the fringe of grinding plate, because of their heavier weight, they would drop to the lower cavity of grinding mill and next be sent into the discharging port by scarper installed at the bottom of grinding plate and finally be discharged out of the grinding mill.
