LUM Series Ultrafine Vertical Roller Mill

LUM Series Ultrafine Vertical Roller Mill Overview

The new LUM Series Ultrafine Vertical Roller Mill is a new type of equipment designed by our company on the basis of digesting and sucking on several advanced technologies. It is milled to the corresponding fine by rolling the material on the rotating grinding disc with a rotating roller. degree. The main technology is reflected in the full contact between the grinding roller, the grinding disc and the material, and the classification accuracy of the grading system. It is suitable for the grinding of ultrafine powder materials such as metallurgy, electric power, chemical industry, refractory materials, especially non-metal such as heavy calcium carbonate and stone paper.

LUM Series Ultrafine Vertical Roller Mill structure features

The active grinding roller system with hydraulic lifting and hydraulic loading; the feeding machine, the grinding roller and the analysis machine adopt frequency conversion speed regulation; the main motor has a coupling device.

LUM Series Ultrafine Vertical Roller Mill application range

The new LUM Series Ultrafine Vertical Roller Mill can be used to produce grinding and crushing materials including: calcite, limestone, pyrophyllite, barite, fluorite, glazing, slag inclusion, wollastonite, kaolin, vermiculite, mica, Feldspar, brucite, spores, potassium salt slag, garnet, quartz, ilmenite, magnesia, magnesium hydroxide, dolomite and other industries.

LUM Series Ultrafine Vertical Roller Mill working principle

The new LUM Series Ultrafine Vertical Roller Mill system consists of screw feeder, main machine, fan, analysis machine, cyclone powder collecting machine, bag collecting machine, piping system and variable frequency electronically controlled high-configuration PLC control system. Among them, the main machine is composed of upper and lower body, grinding roller, grinding disc, hydraulic loading and lifting system, air distribution duct, main motor and reducer. During work, the material to be pulverized is uniformly and continuously fed into the main machine by the screw feeder above the main machine side. Under the centrifugal force of the rapidly rotating grinding disc, the material is thrown to the inner side wall of the grinding disc and brought into the grinding roller and the grinding disc. Engagement area. The grinding roller is loaded by the hydraulic system, and at the same time, due to the difference between the grinding roller and the grinding disc, the material is pulverized by receiving strong shearing and pressing in the kneading zone. The high-pressure and large-flow airflow generated by the fan is mixed with the pulverized powder through the closed-circuit circulation air supply system to form a high-concentration airflow, and is sorted into an analyzer at the upper part of the main machine, and the fine particles are not returned to the grinding disc for re-grinding. The qualified fine powder enters the cyclone dust collector through the analyzer through the airflow. In the powder collecting machine, the fine powder is separated from the air and discharged from the discharge port to be the finished product. During the gas flow cycle, a small amount of excess gas, along with lighter impurities in the finished product, is collected by the branch collector in the system for low-end product processing. Thereby forming a fairly scientific and advanced process.

LUM Series Ultrafine Vertical Roller Mill features

  1. 1, low operating costs. High milling efficiency, low power consumption, and 40-50% reduction in power consumption compared to other grinding equipment such as ball mill Raymond. The wear is small, the special material of the roller sleeve and the lining plate has long service life, which reduces the metal pollution of the product and reduces the running cost. It can be equipped with an external circulation device to further reduce power consumption and improve product accuracy.
  2. 2, low construction costs. Vertical mills and ball mill systems can reduce floor space by approximately 50% and construction costs by approximately 70%. Due to the combination of crushing, drying, grinding and grading, the system is simple, so the construction cost is low.
  3. 3, easy to operate. Equipped with automatic control device for remote control, easy to operate. Equipped with a direct contact device between the roller sleeve and the roller lining, no destructive and severe vibration.
  4. 4, easy maintenance. By adjusting the cylinder to turn the arm, the sleeve and the liner can be replaced in a short time.
  5. 5, less public hazards. Low vibration and low noise. The system is operating under negative pressure and there is no dust spill.
  6. 6, product quality is stable. The material has a short residence time in the mill and is easy to detect and control the product size and chemical composition. The machine is equipped with a high-precision analyzer to classify 325 mesh to 6000 mesh products with high classification accuracy, precise cutting grain and stable product quality.
