Overflow type ball mill lining plate lifting ring groove breaking ability
Overflow type ball mill lining plate of the lifting ring ditch, particularly relating to the cement production industry in a ball mill lining plate, includes a mounting hole in the center of the liner, the liner plate is arranged on the upper surface of the concave ring groove structure, lining plate longitudinal section at one end by a concave and a convex arc smooth transition connection. The utility model adopts the structure, the whole structure of the lining of the highest point to the middle shift, thereby increasing the central mounting hole thickness, so that it is not easy to break, more wear-resistant; in the surface structure, steel ball surface and lining of the concave ring groove full contact, by former point contact now surface contact, more easy to drive the ball, crushing capacity is a traditional ladder lining board several times, increase yield significantly.
Zheng Ore Mining Machinery Company Limited overflow type ball mill from dry mill within a warehouse and mill tailing utilization of wind promptly finished material selected, and transported to storage top collector fully closed type dry ball mill grinding powder selecting device. It is in the dry ball mill is installed, a stainless steel powder selecting pipe powder selecting connecting with tail grinding separation barn choose powder connecting tube two parallel, finished product conveying pipe, trap ( cyclone, bag type dust collector group ), fan, stainless steel material return pipe, ball mill, material order gas closed link. The blower air pumping force, powder selecting pipe under the condition of negative pressure inside the mill and grinding tail will readily form by grinding the finished timely material selection, from materials to finished product pipeline at all levels of the trap, the separation of the finished material is directly mixed classification or unloaded into the repository, the purified air some of the material returning pipe and mill tailing after the separation of the grinding semi-finished delivers to the mill warehouse two front continued to participate in grinding, the remaining portion of the air through the parallel in the air return tube muffler vent, use of mill feed inlet of negative pressure air is provided with a vacuum tube, the grinding head feeding device generates dust suction mill, remove the feeding equipment set up another dust removal equipment costs, a material returning pipe and attached inside the mill grinding body material, observation, operation of the electric eye liner, and the control room monitor are electrically connected in order.
