[ HC Machinery Industry Network ] 1, screen repair and replacement. Screen is made of thin steel or metal punching. When the screen appears the breakdown wear or foreign body, if the damaged area is small, can be riveting or soldering methods complement repair; if extensive damage, should be replaced with new screen. Installation screen should be made with a burr in the side towards mesh, the smooth outwards, sieve and sieve frame to fit tightly. Sieve sieve ring during installation, the overlap in layer rotation should follow the direction of rotation to prevent the material stuck in the lap Department. II Bearing Lubrication and replacement. Mill work 300 hours each, it should be clean bearings. If the lubrication of bearings for the oil, add new oil to fill housing gap when 1 / 3 is appropriate, not more than 1 / 2, just before the operation will often cover the lid-type oil can be tightened a little. When the mill bearings badly worn or damaged should be replaced, and pay attention to strengthening lubrication; use of tapered roller bearings, bearings for axial interval should pay attention to keep it as 0.2-0.4 mm, if not, can increase or decrease Office paper pads bearing cap to adjust. 3, tooth and claw hammer replacement. Crushing parts, the grinding tooth and claw hammer is a feed mill in the wearing parts, shattered the quality and productivity is also affected major parts, shattered teeth and claw hammer should be promptly replaced after wear and tear. Replacement teeth tooth claw crusher claw, the first disc should be pulled out. Pull out before the first round the back of open disc Nut Pieces, with the next round hook wrench nut, then pull out the disc will be dedicated Shiraz. To ensure a balanced rotor operation, for complete sets of replacement teeth should pay attention to, for static balance test should be done after, so that stability of mill work. Tooth claw assembly to tighten the nut must, and pay attention not to leave Spring Washer . Qualified parts should be used for teeth, single tooth claw weight difference should not be greater than 1.0-1.5 grams.

To adjust the angle or U-turn, the entire hammer should be at the same time, corners worn hammer, should replace them all, and note the weight of each Hammer film not a large difference between 5 grams; spindle, disk, positioning units, Pin Shaft, hammer bottles and static balance test should be done in order to maintain rotor balance, to prevent vibration. In addition, fixed hammer the pin and install the pin in the hole because wear will gradually Ground pin, hole will gradually wear big, when the pin diameter than the original size by 1 mm, hole diameter than the original size of mill large 1 mm, the welding repair or replacement in time.
