1. Perbaikan dan penggantian layar. Layar terbuat dari baja lembaran atau besi berlubang. Ketika layar aus atau pecah karena benda asing, jika kerusakannya tidak besar, dapat diperbaiki dengan paku keling atau las; jika area yang rusak cukup besar, layar baru harus diganti. Saat memasang layar, sisi burr dari layar harus menghadap ke dalam, sisi mengkilap menghadap ke luar, dan layar serta bingkai layar harus dipasang dengan erat. Ketika memasang layar cincin, sambungan tumpang tindih dari tumpangannya harus mengarah ke arah putaran untuk mencegah bahan tersangkut di sambungan tumpang tindih.
Second, the lubrication and replacement of the bearings. The penggiling jagung is cleaned after every 300 hours of operation. If the bearing is oil lubricated, it is advisable to fill the bearing housing clearance by 1/3 when adding new oil, and the maximum is not more than 1/2. Just tighten the capped oil cup cover a little before operation. When the penggiling jagung bearing is seriously worn or damaged, it should be replaced in time, and pay attention to strengthen lubrication; if using tapered roller bearing, pay attention to check the axial spacing of the bearing to keep it 0.2-0.4 mm. If there is discomfort, increase it. Reduce the paper pad at the bearing cover to adjust.
Third, the replacement of the claws and hammers. Among the pulverizing parts, the pulverizing claws and the hammer pieces are the wearing parts in the penggiling jagung, and are also the main components affecting the pulverizing quality and productivity. The pulverizing claws and the hammer pieces should be replaced in time after being worn. When the jaw crusher replaces the claws, the disc should be pulled out first. Before pulling out, first open the round nut lock piece on the back of the disc, use a hook wrench to unscrew the round nut, and then pull the disc out with a special puller. In order to ensure the balance of the rotor operation, it is necessary to pay attention to the complete set of replacement when changing the teeth. After the replacement, static balance test should be done to make the penggiling jagung work stable. Be sure to tighten the nut when assembling the jaws, and be careful not to miss the spring washer. The qualified parts should be selected when changing the teeth. The weight difference of the single teeth should be no more than 1.0-1.5 grams.
