Recently, Qingdao Fu Runde Plastic Extrusion Technology Co., Ltd. developed a new wide-width waterproof coil production line successfully passed the expert appraisal organized by Qingdao Science and Technology Bureau. Experts believe that the production line is highly automated and energy-efficient.
It is understood that the waterproofing membrane production line adopts the PCC industrial programming touch screen automation control system, while the FSJ-120×30 energy-saving high-efficiency single-screw extruder is equipped, and the product output is 900 kg/hour, while the motor power is only 200 kilowatts. In the production process, operations such as sheet extrusion, non-woven fabrics, on-line punching, and online winding can be completed in one operation, saving a lot of labor and electricity. Its products can be widely used in fields such as dams, culverts, landfills, pipeline piercing prevention, roof waterproofing, and underground seepage prevention.
The raymond vertical Grinding Mill is used to grind barite, calcite, potash feldspar, talcum,marble, limestone, cream and slag below scale 7 of Moths hardness and 280-odd sorts of non-inflammable and non-explosive stuff in the traded of mining, building material, chemical engineering and metallurgy forpower generation and processing. Thefinal product size of raymond vertical grinding mill is adjustable onrequired in the range of 100-325 meshes.
Working principle
Materials first enter the Crusher to be crushed to smaller size. Then they are lift to storage room by elevator. Vibrating feeder will feed materials into raymond vertical grinding mill chamber evenly and gradually. After being grinded, the powder will be blowed to cyclone by blower. Then the material will be transferred to storage room through pipes, and then will be discharged as final products. The whole processof raymond vertical grinding mill works in a negative pressure environment. First, through pipes, the air from the blower enters the cyclone collector above the storage room along with powder, and then returns to the blower through return pipe. In the way, air can be recycled. There is a powder locking equipment under the cyclone in raymond vertical grinding mill , which isolates the outside positive air pressure and the negative air pressure inside cyclone. And this ensures high productivity. In addition, the residual air and dust under the main unit will be transferred to dust catcher equipment through pipes and be cleaned there. The clean air will be discharged so that environment will be protected.
