Energy saving and emission reduction, help lithium development--LM vertical grinding mill

Energy saving, the need for "lithium" - lithium is closely related to our daily life, laptops, cell phones, Bluetooth headsets and other digital products, new energy trams have a lithium figure.

In recent years, driven by the new energy industry, the demand for lithium ore market continues to grow. Coupled with the relevant national policies, enterprises are optimistic about the development prospects, have planned to build new projects, investment enthusiasm continues to rise.

Help "lithium" development, there are "standing" evidence - lithium ore as a basic raw material for the new energy industry, powder deep processing is essential. Liming Heavy Industry has been working in the grinding industry for more than 30 years, and its star product - LM vertical mill is popular in the market with stable performance, low energy consumption and large output.

LM series vertical mill, also known as roller mill or vertical mill, is a large and energy-efficient grinding product developed by Liming Heavy Industry with the advantageous technology of international famous companies and our more than 30 years of R&D and manufacturing experience, integrating crushing, drying, grinding, powder selection and conveying. The main technical and economic indicators have reached the advanced level.

Structure principle, LM vertical mill is mainly composed of powder selector, grinding roller device, grinding disk device, pressurizing device, reducer, motor, shell, thin oil lubrication station, hydraulic station and other parts.

The working principle is that the motor drives the reducer to drive the rotation of the grinding disc, and the materials to be ground are fed into the center of the rotating grinding disc by the wind-lock feeding equipment. Under the action of centrifugal force, the material moves to the periphery of the grinding disc and enters the grinding roller path. Under the action of the pressure of the grinding rollers, the material is crushed by extrusion, grinding and shearing.

At the same time, hot air is ejected from the wind ring around the grinding disc at high speed and evenly, and the material after grinding is blown up by the high speed airflow at the wind ring, which on the one hand blows the coarse material back to the grinding disc for regrinding, and on the other hand dries the suspended material, and the fine powder is brought into the separator by the hot air for classification.

The qualified fine powder comes out of the mill with the airflow and is collected by the dust collection equipment as the product, while the unqualified coarse powder falls back to the grinding plate under the action of the separator blade and is reground together with the newly fed material. In this way, the whole process of grinding is completed.

Technical advantages

Less comprehensive investment and small footprint: five functions are integrated in one, covering about 50% of the area of the ball mill system, which can be arranged in the open air, greatly reducing the investment cost; the system design is simple and reasonable, saving the total investment of equipment capital.

All-round optimization, lower operating cost: from the details, to achieve lower energy consumption, stronger drying capacity, lower wear and tear of core parts and more convenient maintenance, saving customers' equipment operating costs.

High grinding efficiency and good quality of finished products: The short residence time of materials in the vertical mill reduces repeated grinding and facilitates stable product quality; at the same time, the grinding rollers and grinding discs are not in direct contact, so the iron content in the products is low, which effectively ensures the whiteness and purity of the materials.

High efficiency and environmental protection, reliable operation: The vertical mill is sealed and works under negative pressure, no dust spillage, clean environment, emission standard can reach ≤10mg/m³; at the same time, it is equipped with limit device, avoiding destructive impact and violent vibration, the equipment runs stably with low vibration and low noise.

Simple operation and high intelligence: Equipped with automatic control system, it can realize free switching between remote control and local control, easy operation and labor saving; equipped with automatic lubrication system, it can realize 24-hour non-stop production.
