In order to guarantee the production capacity of this crushing machine and prevent the lining plate from severe damage, the granularity of the rocks and ores that are sent into the crushing equipment should be smaller than the size of the feeding mouth, and generally speaking, its granularity should be 85% of this size.
If the granularity of the mineral particles of the crushed materials is much too big, it may stuck at the feeding mouth and cannot go into the crushing chamber which may influence the feeding speed and cause severe wear to the upper lining plate which be cause some damage to the equipment. Otherwise the rocks may be stuck on the "neck” of the ore accepting and rock dividing plate which bends the main bearing with huge pressure and to make things worse, the upper part of the main bearing may break.
The major of the materials such as ore fines in the rock minerals may be screened when they are sent to the crushing equipment which is made in order to make sure the crusher not to be blocked by the ore fines in the operational process and gives the crushing capacity of the crushing devices to full play.
In the ore feeding process, the customers should feed it in a even and reasonable way in order to prevent accidents resulting from too much quantity of ores fed. For this reason, the operational personnel should learn in mind the interlocking device of the feeding transportation equipment and crusher electricity because the feeding transportation equipment can only work on the condition that the crusher machine is started and normally operated. If the jaw crusher stops working, the feeding and transporting links will immediately stop as well. Whether the discharging and transporting links normally work also has an influence on the ore feeding links. If the discharged materials pile up on the bottom of the crushing device, it may be jacked up and severe accident may happen. For this reason, if the crusher is blocked, it should be stopped immediately.
The relationship of the discharging and transporting machines and the electricity of the crusher is interlocked, that is to say, after the discharging and transporting machines start to run, the crusher can work normally. If the discharging equipment stops suddenly, the impact crusher will stop running. For this reason, the customers should effectively prevent the discharging piling phenomenon in order to make sure the equipment works and run normally. Mobile Crusher
