The powder adhering to the main and auxiliary mills needs to be wiped with acetone or thinner. The blade material is: stainless steel (1GRl 8N i9T i), using a diameter of 3. When disassembling the main shaft of the grinding disc and the auxiliary grinding (impeller shaft), in order to maintain the accuracy of the machine parts, it is strictly forbidden to knock and collide with metal parts The grinding disc and the grinding disc main shaft, the grading impeller and the auxiliary grinding shaft are not allowed to have relative movement (movement).Stainless steel welding rod, the blade is firmly welded to the impeller disk, the welding place is flattened on a lathe or flattened with a banknote wheel. 2 Clean the bearing with kerosene before installation. The candle method (open flame method) is used to strictly check the installation and connection positions of each part for air leakage to ensure the normal operation of the equipment. Cleaning up the dust Industrial double shaft shredder machine Suppliers removal cabinet; When cleaning the dust removal cabinet, first turn off the induced draft fan and cut off the power supply. The inner surface of the main and auxiliary mills must be kept smooth. Then, open the recycling powder discharge valve, and check after the powder is discharged and cleaned: A Check whether the binding of the dust bag is not tight. 4Select domestic high-temperature grease grades: 70 1 4-1l, temperature range (-40-120) Replacement of main grinding shaft and bearing Remove the two sets of V-belts, loosen the nuts, use the pulley puller to remove the grading impeller, unscrew the bolts to take out the main grinding assembly from the grinding body, and place it on a vise for disassembly.Select foreign SKF high temperature grease, temperature range (one 30 one 120 ~ C). Cushion the impeller shaft (secondary grinding shaft) at the end of the belt pulley with non-ferrous metal or wood. Knock from bottom to top to take out the auxiliary grinding shaft with the mortar head to replace the auxiliary grinding shaft and bearing. Matters needing attention when assembling the grinding disc 1 Load the grinding disc adjustment pad first, and then put the grinding disc on the main grinding shaft. Keep the bearing parts clean to avoid contamination of bearing grease.
