Zhangjiagang Leyu Yiyi Machinery Factory is located in Leyu Development Zone, Zhangjiagang. Our factory has many years of experience in manufacturing plastic mills, and fully absorbs advanced technology and management methods at home and abroad. Research, design, manufacture and sales of plastic machinery.
The PE mill main shaft is refueled once a shift, but care must be taken to clean the oil passage immediately if the oil in the oil cup is not lost or the loss is too slow. It is forbidden to enter the metal block into the limestone mill, otherwise it will damage the grinding roller and the grinding ring, and even the center hanger. The feeding should be uniform and should not be ignored. Excessive feeding will block the air duct, reduce the output value, burn the motor easily, and feed too little will also support the output value. Feeding particle size: Hard material is preferably less than 15 mm in diameter, and soft material can be 20 mm in diameter. It is forbidden to add bulk material to the machine.
Air volume adjustment: The air volume control valve located on the intake pipe of the fan is generally opened to a larger position and adjusted according to the fineness and output value requirements. The regulating valve located on the exhaust pipe of the exhaust gas outlet can be adjusted to the inlet without dust emission. The air volume is small and the fineness is high. However, it should be noted that the air volume is too small, and the material in the air duct below the main unit is easy to deposit. Please adjust it properly. Fineness adjustment, according to the size, hardness, water content, specific gravity of the material, the thickness of the processing is also different, the upper analyzer can be adjusted, the rotation speed is high, the fineness is high, the rotation speed is low, and the fineness is low.
The end of the grinding ring of the PE mill is not less than 10mm. When parking, the feed is stopped first, the main machine continues to smash, and the residual abrasive is continuously milled. After about one minute, the main motor and the analyzer motor can be turned off, the milling operation is stopped, and then the fan motor is stopped. Blow off the residual powder.
