Mobile Crushing Plants For Construction Waste is commonly used in the crushing of limestone in cement plants. This machine has the unique advantages of large crushing ratio, short crushing process, simple production process, fine output granularity, and low operating cost. In the use of limestone crusher, maintenance and maintenance can not be ignored, some precautions are introduced below.

General requirements for single stage crusher maintenance:

1. After the machine is started for 5 minutes, when it is confirmed that there is no abnormal situation, whistle is fed to the mine. After the crusher stops feeding, the machine can be stopped after it is confirmed that there is no residual ore in the crushing chamber.

2. Check the lubricating parts every 5 days, add grease to the bearings of each part every 10 to 15 days, each time not less than one oil cavity (main bearing), the machine uses calcium-sodium-based sliding Grease, often check whether the bearing temperature exceeds 70 \u0026 deg; C, clean the bearing at least once a year.

3. The rotating parts such as the flywheel (coupling) of the crusher must be provided with a protective cover.

4. Hammer head: Generally, a set of hammer heads can crush 200,000 tons of ore. However, due to the different properties of the ore, the life of the hammer heads is also different. When the round holes of the hammer head are ground to the width B At 3/5, if the round hole of the hammer head is worn or squeezed and deformed into an oval shape, and its deformation amount is A = D-d \u0026 asymp; 15mm, the hammer head should be re-inserted with a hole sleeve. When the hammer head wears the original weight, At 60%, a new hammer head should be replaced in time, otherwise the production capacity will be affected. The original hammer head can be piled with abrasion-resistant alloys and used after repairing.
