Cement vertical mill common faults and treatment options

Cement vertical roller mill during use due to poor working conditions, often vertical grinding mill rolls, disc liner wear, vertical roller mill operation grinding roller bearing wear and gear chamber leakage and other common problems. Vertical grinding mill roll body and liner wear during use, once with the gap between the body and will cause wear liner intensified, combined with hot air and cement particles on the mating surfaces of constant erosion, resulting in the generation of a trench, resulting impact collision occurred between the body and the liner, the liner making serious cracks or fracture, damage to the machine, especially damage to the gear unit, resulting in a vicious incident. Once this kind of problem occurs, general repair methods are difficult to solve, replace costly; vertical grinding mill roller assembly requirements more stringent bearing companies generally use dry ice cooled bearing on the way the assembly. Once a gap occurs between the bearing and the bearing chamber, it will affect the normal operation of the bearing, resulting in bearing fever, severe burning phenomenon will cause bearing; vertical roller mill reducer leakage not only affect the appearance of the machine, and waste oil, to maintenance of equipment maintenance caused great trouble.        These problems are generally difficult process for welding repair resolve bad soldering iron and easy to parts caused by welding more serious secondary damage, the replacement cost of a long high time. Western countries currently use more polymer composites scene solve this kind of problem, which is widely used there is beauty Wah series. The compressive strength of the material unique, good plastic deformation and superior machining performance, when repairing these problems reflect the fast, convenient, durable features, enterprises save a lot of valuable downtime downtime, and allows businesses to learn repair and maintenance of a new technology, in the face of similar problems again, companies can independently solve the first time. http://www.crusherproduct.net/product/lum-ultrafine-vertical-roller-mill.html

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands
