After a comprehensive review of the wet mill equipment and secondary grouting user friend after buying a wet ball mill equipment installation work, you must conduct a comprehensive review of all parts meet the installation requirements before proceeding secondary grouting, as a precautionary measure, in the preliminary examination is completed After, you can first of all anchor bolts embedded hole before filling part of cement mortar, grout curing until after the expiration of mill price, you can tighten all anchor bolts, and then all of the quality indicators mill equipment installation projects to conduct a comprehensive review, so but also on the quality of the local sub-indexes to adjust, and then the gear housing cover is good, you can carry out secondary grouting. Before secondary grouting, first of all to chisel off basis cleaned, then stand a good template and fix it, in order to carry out secondary grouting, specific requirements are: not only the bolt holes in the slurry to fully vibrated dense, And all the floor (seat) inside the pulp layer should be vibrated dense, in addition to the base layer, the outer surface of the second watering should be higher than its bottom plane about 25 to 30 mm, it will give the base layer of solid concrete inside, outside the protection layer at the bolt is loose or broken, they can still play a certain degree of "non-slip" effect, prevent the occurrence of accidents. Of course, it may, after inspection, the first of the main bearing basis secondary irrigation, then part of the drive for secondary grouting. Regardless of the method for secondary grouting, watering should be a secondary layer of reasonable maintenance, to prevent it from cracking. Mill equipment is one of the main products Dahua Machinery Co., Dahua Machinery is the largest manufacturer and supplier of ball mill, located in the Central Plains, and convenient transportation, production quality assurance, and excellent service in the mill has a good reputation in the market. Scratches and cutting grooves in the metal plastic deformation occurs in the sides and front piled high strain rate plastic deformation has occurred so that the internal dislocation pile of metal to form cell-like structure, the nature of hard and brittle, and then after repeated rolling produce strain fatigue crack dry ball mill, hard and brittle nature, and then after repeated rolling, producing strain fatigue crack extended to the surface, resulting in debris shedding, fatigue wear, ball at impact stress of repeated changes, contact stress and the role of shear stress by repeated impact, compression and sliding between each other, in the alternating pressure and shear stress, causing alternating Hertz contact stress at the surface of the material to produce maximum alternating shear stress, contact the edge of a peak tensile stress, resulting in sub-surface brittle phases, inclusions or voids at the fatigue crack, crack propagation and intertwined, and finally to the ball and wear skin peeling, if cracks in the deeper parts of the mill manufacturers, and along brittle phases and defects to internal expansion, the formation of a large crack depth, crack will extend to the surface of the merger, it will make the ball fall off the surface of a block, the ball surface fatigue wear, brittle wear, in a wet ball mill slag for use in mines wear medium (of the electrolyte solution) and the wear conditions act on the material surface, the occurrence of corrosion and wear, wet grinding grinding media consumption over dry 5-7 times lower corrosion mill system failure rate is much material consumption much higher than the corrosion and wear alone because of material consumption and the loss rate of corrosion damage to the mechanical properties of the material surface, so that the material is accelerated wear, wear constantly produce "new" material surface, but also improves the corrosion rate. These are analyzed Dahua Machinery Co., Ltd. for the ball in the form of wear mechanisms of failure, to improve the life of the ball, the material should have high hardness, high impact fatigue strength, high fracture toughness and impact toughness and some other column mechanical properties, on the other hand, slag mill parameters also affect the wear and fatigue life of the steel ball. Used ball mill, ball mill, Yunfu City, Dahua machinery provided by Gongyi City Dahua Machinery Limited. Gongyi City Dahua Machinery Co., Ltd. (www.dhqmj.com/) strong, credible, in Zhengzhou, Henan's industry-specific equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Dahua machinery and you hand into the brilliant, for a better future!
