Introduce Three Optimization Operation of Vertical Mill

The main purpose of the optimization operation of Vertical Roller Mill is to realize high quality and stable production. There are many factors influencing its optimization operation including the production flow of powder grinding, the types and specifications of the vertical mill, the physical property of the materials fed into the grinding mill and the feeding amount and the uniformity, the fineness of the final products, the ore separation efficiency and the cyclic load and grinding pressure, and all the factors interact with each other. This paper will focus on the three optimization operation of vertical mill. (1) Adjust the material feeding a. Adjust the water content of the materials fed into the mill. When the average water content of the materials exceeds the drying load of the Vertical roller mill operation, the materials will stick onto the roller bed and form a bugger layer, which will reduce the powder grinding efficiency, for this reason, the water content of the materials fed into the grinding mill should be strictly controlled within 12%. b. According to the load of the grinding mill, adjust the material feeding amount. To bring the efficiency of the grinding mill into full play and make it reach high productivity, it is necessary to maintain stable and proper material feeding amount. The workers can timely adjust it according to the change of the power and electric current of the LUM Series Ultrafine Vertical Roller Mill to make the grinding process return to normal. (2) Adjust the cyclic amount When the grinding mill begins to work normally, it is not necessary to change the cyclic amount so as not to influence the stability of the system. Generally speaking, when the materials are configured again or the granularity of the materials changes, the cyclic amount will be changed. Timely adjust the cyclic amount according to the electric current of the cyclic bucket and the changing condition of the titration value of the calcium carbonate to maintain it within a proper rang. (3) Adjust the hot wind Vertical Roller Mill is a special machine among the air-swept mills. Only when its dying ability and the powder grinding ability reach dynamic balance can the system realize stability. For this reason, it is necessary to timely and correctly adjust the hot mind to satisfy the requirement of the powder grinding process for drying according to the working condition. The adjustment includes the temperature and the amount of the hot wind. The adjusting principle goes like this: on the premise of ensuring the safety of the equipment, reach high drying speed, balance the powder grinding ability and drying ability and reduce the heat loss.

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
