Structure and hardness of the impact crusher hammer Analysis

Impact crusher (sand making machine) shape hammer a lot, in order to manufacture and easy to maintain, at home and abroad are mostly rectangular hammer. Soviet hammer material is generally 45,65Mn, 72Mn steel, heat treated to a hardness of HRC50 edge work a 55,20Cr carburizing, carburizing layer depth 0.8 a 1.2 mm, working side HRC56 ~ 62. VSI Sand making machine on the use of three composite steel mill for export use. Hammer life is generally not less than soc hours. According to research and test the Soviet Union, the impact hammer crusher consider using a cylindrical (diameter 18 mm) can prolong life. .5 To 1 times. After sand making machine 3oCrMnsi to life as the life of 1,45 hammer hardened steel hammer for 0.87,65M steel after quenching for hardening of 0.6 even after 0.9,08CrisNigTi 5, spit oCr after quenching is 1.12, zZCrNi3 quenching l 2.25. American Champion's Magnttmzz.5 righteous soul type grinder 4 (75 kW, 10 tons / hour), hammer actual life has reached 1000 hours, a hammer can crush 10,000 tons of feed. According to information on the impact of the American Sand hammer hammer against the four corners of the main wearable surfacing wear layer to solve. Some sprayed on the platinum chromium alloy steel hammer (Cu72%, Z two 25%) powder to achieve '{wear purposes. http://www.crusherproduct.net/product/b-deep-rotor-impact-crusher.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...
