Four-roll crusher Maintenance precautions when using fou

Four-roll crusher in the mining equipment is often used to the crusher equipment, broken effect is very good, with a lot of features, which is why it is so good in the market sales reasons. But such a good equipment if not properly maintained, it will be a problem, if the equipment failure, followed by will reduce the efficiency, then the following HSM look at the use of four-roll crusher maintenance precautions.

1, crusher repair, when re-assembly of the upper crushing roller, clamping shell coupling, round nut and coupling bolts should be strictly controlled its tightening torque.
2, the crusher must be no-load start, must be checked before the start and remove the remaining material within the crusher.
3, check the main and auxiliary gear box oil tank, to ensure adequate supply of oil.
4, start the crusher to reach the normal speed, and in the absence of abnormal circumstances to start feeding.
5, maintenance and repair If you want to open the main and auxiliary gear box box cover, in the re-installed before the need to replace the rubber seal and static sealing surface evenly coated with a layer of sealant to prevent sealing oil, oil The
6, regular sampling Check crusher product size is in line with the requirements.
7, crusher main, vice drive gear box with gear oil lubrication, summer and winter should be timely changes in the box lubricants.
8, change the crusher material strength, size or crushing ratio, should be re-set the buffer cylinder nitrogen pressure. The size of the pressure to meet the crushing roll needs to be moderate. Excessive tightening forces the machine to wear and increase power consumption. A small pressing force will increase the oversize of the crushed product and cause the active crushing roll to exhibit frequent vibrations.
9, the normal stop must stop the feed in advance, all the material after the machine to stop the crusher to stop.
10, crusher, the lower section of the crushing roller translation of the rod device bearing grease lubrication, the design requirements of 2 or 3 calcium-based grease. During normal production, the oil cup cover should be tightened for one week for each week to inject grease.
11, crusher such as long-term disabled, or the initial start, should be used in advance to turn the pulley 2-3 weeks to confirm the machine running freely, and then the motor "jog" several times, when the motor rotation direction, Officially started crusher.
12, in any way to the crusher for the material, must be equipped with a reliable rust removal device to prevent other chores into the crusher.

No matter what kind of mechanical equipment, we have to do maintenance, so that both to avoid the failure, while avoiding the work efficiency of the equipment, but also to extend the service life of the equipment, so be sure to pay attention.
