Raymond bearing Hugging you know why?

Raymond mill bearing Hugging is generally greater friction bearing rotates said, why the bearing friction will greatly? Today from Henan Tianrui machinery to introduce the next mill bearing friction big reason. Bearing lubrication state is not good, bearing a long time to work in conditions of lack of oil or without oil, it will lead to greatly reduced the flexibility of bearing operation, the bearing slide difficult; sludge and dirt inside the bearing too much, since the bearing cavity foreign body occupies most of the space, and a smaller available space occupied by the grease, resulting in poor bearing lubrication state, it is difficult to rotate the shaft. Bearing clearance is too small, it can lead to difficulties in bearing operation, the bearing locking. Raymond mill bearing locking solutions to regularly add a suitable quantity of bearing grease and should be cleaned regularly bearing cavity foreign bodies and impurities, but also appropriate to increase the bearing clearance, the bearing operating flexibility. Also pay attention to Raymond maintenance and regular maintenance, the following is Raymond mill maintenance and repair methods: 1, for the mill normal, should develop equipment "equipment maintenance safe operation of the system" in order to ensure long-term safe operation of the mill, at the same time have the necessary repair tools and grease and the corresponding accessories. 2, Raymond after a period of use, maintenance should be carried, while roller grinding ring blade overhaul replacement of wearing parts such as processing, grinding roller device before and after the use of the connection bolts and nuts should be carefully examined to see if there are loose phenomenon, whether to add a little grease. 3, roller device in use around the time more than 500 hours to replace the roller, the roller jacket of the rolling bearings must be cleaned, damaged parts should be replaced, fuel pumps and hand tools available grease gun. 4, fine adjustment, based on the size of the material, hardness, moisture content, different specific gravity, thickness of the process is different, you can adjust the top of the analyzer, high speed, fineness, low speed, low fineness. Improve the fineness, output will be reduced accordingly, if it is mainly the fan speed debugging, the user can be flexible. 5, ring roller mill scrap the limit, the remaining minimum wall thickness not less than 10mm. 6, Raymond machine stop, stop feeding, the host continues 盍, the residue of abrasive proceed milled about a minute, turn off the main engine of the motor and motor analyzer, stop grinding work, which then stop the fan motor to blow residual powder.

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
