ultrafine mill common faults and exclusion methods

ultrafine mill of the working principle: large pieces of material by jaw (hammer) broken, after the material hoist to the storage hopper, and then by the electromagnetic vibration feeder to the material evenly sent to the grinding chamber for grinding The After the crushing of the powder and then by the separator for powder, in the role of the impeller, does not meet the fineness of the material into the crushing chamber to re-milling, meet the requirements were sent to the cyclone collection device, after The finished product by the discharge port. The whole system is closed. ultrafine mill common machine failure and troubleshooting methods: 1, ultra-fine mill no powder or powder significantly reduced, the reason may be that the grinding chamber is not closed, resulting in dust suction, or the mixer power is too large or too small, resulting in dust can not pass; The troubleshooting method is to check the air tightness and the proper adjustment of the finder 2, the finished product is too large or too small, the reason may still be the election powder wind speed is too large or too small, resulting in inappropriate dust can pass. The exclusion method is to increase the wind speed to the appropriate 3, the host current rises, the machine temperature rises, the fan current drops. Reason: excessive feed, the air duct is blocked by the material, affecting the exhaust pipe exhaust, circulating air heat is the main current, machine temperature, fan current drop. Remedy: reduce the feed, remove the duct powder; into the machine material temperature control at 6 ℃ below. 4, ultrafine mill host noise a lot more shaking. The reason may be: the feed is too small, grinding roller wear serious, loose anchor bolts; or excellent material, the machine milling effect, the machine caused excessive wear and damage; machine internal key grinding parts wear serious, key components run away Track, run unstable. Remedy: adjust the feed volume, replace the grinding roller grinding ring; replace the other materials 5, the election device vibration. Reason: The powder is serious. Remedy: Replace the impeller and reinforce the screws to prevent vibration 6, ultrafine mill roller device into the powder bearing damage. Cause: the body off the oil, or seal damage, long-term lack of maintenance and cleaning. Remedy: timely refueling, regular cleaning and replacement of oil seal. http://www.ht-rent.net/product/grinding-mill/lum-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
