Quick Lime Vertical Mill
Quick lime vertical mill is my company in the extensive use of advanced technology at home and abroad based on, combined with years of experience in the production of a variety of mill, design and development of a set crushing, drying, grinding, grading conveying in one of the milling industry is the ideal equipment. He covers an area of about 50% of the ball mill system, and can be arranged in the open air, so it can reduce the investment cost.
Quick lime vertical mill main powder selecting machine, grinding roller device, the grinding disc device, pressure device, a speed reducer, a motor, a casing, etc., part of the composition. Separator is an efficient and energy saving device. Grinding roller is used to crush the material of the material. The disc is fixed on the output shaft of the reducer, grinding roller material. The pressure device is provided with a component that provides the grinding roller with enough pressure to crush the material.
Work in the vertical roller mill grinding roller and the grinding disc is not in direct contact, so the noise is small. Adopt the whole sealing system, the system is operated under negative pressure, no dust, environmental cleaning. Due to the work roller is not and direct contact with the disk, and the grinding roller and the lining board is made of high quality materials. Therefore, the use of long service life, less wear and tear. Equipped with thin oil lubricating station, roller bearing with thin oil lubrication to ensure bearing working under the low temperature and the oil clean conditions, prolongs the service life, makes the equipment run continuously and reliably.
Vertical Roller Mill widely application
Quick lime vertical mill is our company in the vertical roller mill technology maturity, vertical grinding product advantages become increasingly prominent situation, absorption of the European advanced technology, combined with our many years of advanced milling machine design and manufacturing philosophy and market demand, R & D team through continuous technology innovate upgrade. Vertical milling machine is widely used in cement, electric power, metallurgy, chemical industry, mineral industry material mill.
Quick lime vertical mill unique advantages
- Low operating costs
Wear less: because of the work roll grinding is not and direct contact with the disk, and the grinding roller and the lining board is made of high quality materials. Therefore, the use of long service life, less wear and tear.
Low milling energy consumption: the roller on the disc to direct rolling ground material grinding, low energy consumption, and milling system compared to save energy consumption by 30% ~ 40%.
- High efficiency grinding
Output: different types of products to meet customer demand for different materials production needs, relative to the traditional mill, the output is greater, more efficient.
Hydraulic pressurizing device: by hydraulic pressure can increase the size of the grinding force, which can increase the yield, improve grinding efficiency.
- Extensive grinding materials
With hot air conveying material, it can control the air temperature and the final moisture content of the product to meet the requirement of the product. Can be dried into the ground water up to 15% of the material, wide range of applications.
- High quality
High purity of finished products: roller sets and liner board is not direct contact, and other limiting device, the product contains very little iron, and the mechanical wear iron is easy to remove, for grinding white or transparent material, the product's whiteness and purity is high.
High accuracy: according to the different requirements of different products, the selection of the powder machine were used in the cage type selection of powder machine (dynamic and static) and the selection of the conical rotor (high efficiency and dynamic selection machine) two, improve the accuracy.
- Easier operation
Intelligent control: LM vertical mill system is equipped with PLC/DCS automatic control system, can realize remote control, operation is more simple.
Maintenance more convenient: through the maintenance of oil cylinder, flip the arm to replace the roller sets, lining board, more convenient, reduce downtime losses.
Quick lime vertical mill working principle
Main motor through the speed reducer drives the grinding disc to rotate, while the hot air into the air from entering the mill body, the material through a feed fall in the center of the disc, under the action of centrifugal force, material from the disc center to edge uniformly moving, through the upper millstone grinding roller area by grinding roller of roller compacted, the bulk material is crushed, fine material by extrusion forming bed material interparticle breakage.
Crushed materials continue to move to the edge of the grinding disc, until the wind ring strong airflow taken and flow with material, larger particles under its own gravity again fall to the disc to smash, the rest of the material, with the air into the high dynamic separator, powder classification, in the role of efficient dynamic blade separator, does not meet the requirements of the fineness of the material back to the millstones for grinding, and in line with the requirements of the fineness of the material with the gas flowing through the pipes into the pulse dust collector to collect, by discharging device discharge is refined powder.
Host within the mixed material of iron and other hard grinding debris with the material is moved to the edge of the grinding disc, due to its own weight and can not be blown up by the wind, fell mill cavity is mounted on the disc at the bottom of the scraping plate scraped into the slag outlet after discharge the external host.
