Under normal circumstances, feed pulverizer maintenance, there are three main aspects of the job.

Screen repair and replacement

Screen by the thin steel plate or made of metal punching. When the screen appears worn or foreign body breakdown, if the damage to the small size that can be used up or riveting Ways Soldering repair; if extensive damage should be replaced with new screen. Installation screen should make Sieve burr side with North Korea, the smooth outward, screening films and screen frame to fit tightly.Central sieve sieve films at installation, lapping the inner crops for rotation should be along the rotation direction to prevent the material stuck in the lap Department.

Bearing lubrication and replacement

The bearings should be cleaned when pulverizer works 300 hours,. If the bearings for the oil lubrication, add oil when the new chock full of gaps 1 / 3 is better, with a maximum of 1 / 2, operating the former simply regular oil lid cover can be tightened up some. When the pulverizer bearings serious wear or damage should be promptly replaced, and attention to strengthening lubrication; the use of tapered roller bearings, attention should be paid to check bearings axial spacing, so as to maintain for 0.2-0.4 mm, if there is discomfort, can increase or decrease in Bearing Caps Department to adjust the pad of paper.

Tooth and claw hammer replacement

Parts of crushing, grinding teeth and claw hammer pulverizer feed are the wearing parts, but also affect the quality and productivity to crush the main parts, crushing teeth and claw hammer should be promptly replaced after wear and tear. Crusher claw tooth claw tooth replacement should be first pulled out the disc. Pulled out before the first round the back of open disc lock nut films, with a round under the hook nut wrench, and then dedicated the disc out of Shiraz. In order to ensure the functioning of a balanced rotor, for complete sets of replacement teeth should pay attention to, for to do after the static balance test, so that job stability grinder. Tooth to claw assembly must nut tightened, and not to pay attention to spring-loaded gasket leak. Teeth should be qualified for selection of cases, the weight of a single tooth claw bad should be not more than 1.0-1.5 grams.

Hammer Hammer Pulverizer some symmetric, when the hammer pulverizer monoceras blunt, may use negative transfer Kok; if one end of corners have been worn, they should use a U-turn. Transfer angle or U-turn at the time, all should be at the same time hammer, hammer corner wear, they should replace them all, and pay attention to the weight of each hammer may not be big bad 5 grams; spindle, disk, positioning units, pin, hammer installed after the static balance test should be done in order to maintain rotor balance, to prevent vibration. In addition, fixed-hammer pin of the pin and install the hole because of wear, will gradually ground pin, hole will gradually wear big, when the pin diameter smaller than the original 1 mm diameter hole than the original size pulverizer large 1 mm, shall promptly repair or replacement of solder.
