Hard plastic vacuum extruder product description Linyi Jiang of brick machinery factory two-stage vacuum extruder is much research I plant at home and abroad advanced experience of independent research and design of new manufacturing equipment manufacturers, which mainly use coal gangue, fly ash , shale, clay and other raw materials, is the production of hollow brick and shale, coal gangue, fly ash brick ideal equipment. Up and down the structure of the higher agitation using biaxial extruder feed vacuum hard plastic extruder production line, the advantage of a good raw material for processing, drawback for sealing performance is poor, due to the long axis of the two stirring vacuum hard plastic extruder, and the number of installed ten different pitch protection sleeve, mixing knife dozens of varying severity Linyi hard plastic vacuum extruder to form the axis of rotation is inevitable beating, causing the shaft mounted on two conical seal gland raw materials in the region beating conical seal is formed between the sleeve and the raw material to produce the vacuum of space caused by the leak brick hard plastic extruder, resulting in commissioning new units have not achieved display ≤-0.092 vacuum, not only that, the feed less, the vacuum gauge needle will bounce up and down inside, resulting in brick production can not be effectively guaranteed. Hard plastic vacuum vacuum extruder production line _ _ Jiang of hard plastic extruder machinery factory brick by brick machinery factory Linyi ginger male. Linyi Jiang of brick machinery plant (www.btmach.com) (www.btmach.com) strong, credible, in Linyi, Shandong and other industry-specific equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead ginger male brick machinery plant and you work into the brilliant, for a better future!
