    Crusher is our most popular stone crushing equipment, bulk material through the jaw crusher crushed, through the crusher for further rock crusher crushing and sorting grain type before we can meet the specifications of the stone building standards, impact crusher rotor structure mainly by the impact of the way to make the stones produce a stone or stone blacksmith and crushed stone, gravel and crushed grain through rotor counterattack after more rounded stones conform specifications.
    Hammer crusher is an important wear parts, and withstood the strong impact of various materials and wear high-speed rotation, the consumption is very large, in order to propose specific measures for improvement, we must understand the reasons for the wear caused by the hammer, the following combination of hammer on their own situation and experience to analyze the impact crusher hammer wear causes:
    First, improper selection: hammer wear resistance and hardness of neither alone, nor alone with toughness related, but complement each other high hardness and good toughness. Currently the high manganese steel is the material used hammer, hammer mill if the surface is not subjected to sufficient stress, produce enough hardened layer, due to the large manganese austenitic stability, and its high content of austenite organization, its surface lower hardness, high wear resistance is not natural.
    Second, the impact of the actual working conditions: high fierce steel hammer did not form in their work effectively hardened layer, so that the hardness of the hammer job performance can not play up to the standard required to work, so do not wear very hammer, life is greatly lower than the life expectancy of the design.
    Third, water treatment unreasonably tough: high manganese steel hammer material needs to be tough water treatment to increase its hardness and toughness, but the manufacturer during tough water processing, processing temperature, holding time and heating rate no strict control, and there is no oxidation and decarburization noted when insulation, it is likely to cause the production of substandard hammer, thereby causing severe wear in use.
    Fourth, the friction hammer hammer crusher and materials: the crushing operations, only a few materials can block into the combat zone, and most of the material, especially bulk materials, only one end into the strike zone, so cause sliding friction materials and hammer and adhesive powder back panel make more serious friction, causing its rapid wear. In view of this situation, Hongxing Heavy users of the materials for the pre-treatment is recommended, as far as possible to the material in the powder, dirt and moisture advance screening.
    Fifth, the broken material substandard equipment requirements: different models of crusher have to adapt their broken material, if the hardness of the material outside the specified range of the device, it will increase the degree of friction with the hammer, causing hammer wear.

    Hot drop galvanized material tubing useful for?

    Sizzling inspired metallic Uses: mainly utilized for carrying natural gas, home heating.
    Within gasoline, green house, heating up while using types of iron tubing is galvanized tube, galvanized tubing as mineral water piping, a lot of corrosion within the pipe, going yellow water quality not only sanitary, but is not mixed with simple interior wall structure to reproduce microbes, rust due to normal water metal content articles are too high, severe problems for human well being. Sixties and also 70s, the overseas the western world developed brand-new tubing, and also gradually turn off the galvanized tube. Chinese language Secretary of state for Structure and various four ministries furthermore granted the file expressly impaired gal water pipe via Two thousand forward, the latest district now has rarely used your wintry water line galvanized tube, quite a few cellular material by using a water conduit gal water pipe.
    100 200 RECTANGULAR HOT DIPPED GALVANIZED STEEL
    Galvanized conduit: To improve your oxidation resistance of your metallic pipe, inspired metal water pipe with regard to basic. Inspired material scorching galvanized and also electro-galvanized two, thickness inspired sizzling above gal, electro-galvanized affordable, the counter may not be smooth.
    Scorching inspired water pipe is the molten metal answering with the straightener matrix metal layer, to ensure the substrate in addition to covering combined both equally. Incredibly hot dip galvanized precious metal pickling is definitely the primary, so that you can take away the metal surface of the metal oxide, after pickling, cleaning tub by way of blending a great aqueous answer regarding ammonium chloride and also zinc chloride or ammonium chloride and zinc oxide chloride aqueous solution and after that in to incredibly hot drop tank. HDG features a finish reliability, powerful bond, durability and also other rewards. The substrate while using smelted precious metal bathroom undergo difficult natural plus substance response to sort a new corrosion-resistant zinc-iron blend design snug covering. Mix part plus the 100 % pure zinc oxide stratum, material substrate built in. Consequently, it is solid resistance to corrode.
    1 5 INCH BS1387 GALVANIZED SCAFFOLD TUBE
    A single, the particular feel on the zinc level: material sample has been sunken within a copper mineral sulfate option more uninterruptedly is not crimson (copper coloring)
    Two, the counter superior: floor inspired aluminum inspired part need to be complete, may possibly not have not really plated destinations and bubbles are available, allowing for slightly tough surface and also the existence of local malignancies zinc.
    Three or more, zinc shell excess fat: Based on the demands, inspired precious metal conduit can be used as zinc oxide level excess fat measurement, the common valuation of no less than 500g / block multimeter, ones for about virtually any example 480g sqm.
