Analysis on Vibration of Hydro Cone Crusher

Stone crusher project report has good structural features and dynamic characteristics, so it canmeet different process requirements in the handling of different types of ores.Taking analysis on the nonlinear vibration situation, we can deep reveal itsexcellent characteristics in order to better direct the production. Hydrocone crusher is composed of power part, transmission part, and working part.Vibration situation of hydro cone crusher in work is complex, including highfrequency micro-amplitude vibration around two Cartesian axes which are parallelto the water level, and circular vibration in horizontal plane, which is mainform of vibration. In working process, materials are always acted by forcewithin crushing chamber, and participate in vibration, becoming an importantcomponent of vibration systems. Actual system vibration of hydro cone crusher isa two-degree-freedom nonlinear vibration. (1) Analysis on hystereticstrength Hysteresis is symmetrical with the origin in a movement China stone crusher manufacturers, it is piecewise linear odd function with respect to thematerial characteristics. When the gap between movable cones is larger thanshatter value between materials in crushing cavity, movable cone begins to loadmaterials forwardly, so that stress and strain in a material layer accumulateand increases, being in the stage of elastic deformation. When the relativedisplacement of movable cone reaches to limiting displacement, breaking bodywill be in a forward unloading state and hysteretic force eventually be reducedto 0. Due to crusher's process is circular and symmetrical, in back-loaded andunloaded conditions, bodys movements are similar to the results of thepreceding analysis. (2) Equation of hysteresis As the hysteresis issymmetric to coordinate origin, we can establish hysteretic strength equationmaking use movable cone displacement and speed. Analyzing and calculatingequations, we can get that the actual vibration frequency of China Jaw and cone crusher is not only related to frequency of vibrator, quality ofmachine and elastic stiffness of rubber spring, also associated with theparameter of materials.

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...
