LM vertical roller mill

Product Details

01/Product Features

LM vertical roller mill is an efficient and energy-saving product that combines 30 years of mature vertical grinding technology, successful foreign experience, and our company's technological innovation and upgrading, achieving the localization of high-level vertical mills. It adheres to advanced milling technology and multifunctionality, adopts reasonable and reliable structural design, and cooperates with advanced process flow. The uniqueness of this product lies in its industry segmentation, tailored for exclusive markets: vertical coal mills specifically designed for coal powder preparation in the power, steel, and coal injection boiler industries, vertical ore mills specifically designed for non-metallic mineral grinding, and vertical slag mills specifically designed for slag and fly ash production. Such meticulous work makes customers' choices more targeted and rational. Big guys have great wisdom, and it is imperative to replace foreign brands!

02/Advantages and Highlights

Easy to operate and reliable in operation

Equipped with an automatic control system, it can achieve remote control and is easy to operate.
Excellent quality of finished products

Adopting the principle of material layer grinding, the material has a short residence time in the mill, less repeated grinding, low iron content, and high whiteness and cleanliness of the finished product; The grinding curve of the specially designed roller sleeve and lining plate can grind to the required fineness (0.045-0.02mm) in one go.
High environmental standards, more automated

The equipment runs stably and has minimal vibration, resulting in low noise. The system is fully sealed and operates under negative pressure, with no dust leakage and a clean environment. The emission standards far exceed international standards. And equipped with an expert automatic control system, it can achieve free switching between remote control and local control, with easy operation and labor-saving.
Low comprehensive investment cost

Integrating crushing, drying, grinding, and conveying, the process flow is simple, the system equipment is few, the structural layout is compact, the footprint is small, only 50% of the ball mill, it can be arranged outdoors, the construction cost is low, and it directly reduces the investment cost of the enterprise.
