Before embarking on a maintenance journey for your crusher, there are three types of maintenance that you would do well to understand regardless of the type of crusher youre working with.
(1) electrical equipment failuresat the run time hydraulic cone crusher, many electrical failures may cause the material blocking: the motor electrical shutting down; the bearing being damaged; the drive belt slipping or even burning.Appropriate measures: the workers should frequently check out the machine to ensure its normal operation and regularly overhaul the machine to ensure that the parts are all in normal use.(2) production process failuresthe production capacity of cone crusher is 90-110t h.When the amount of entering limestone is too large in per unit time, or the limestone is mixed with iron or hard objects, the hydraulic cone crusher is possible to block due to overload or material stuck.Appropriate measures: the production capacity of the hydraulic cone crusher should not be exceeded during operation, in case that the overloading machine will be blocked and thus affect the crushing effect.Hard materials are not allowed to enter the amchine, so the fireman should pick up the metal hardware debris on the net chain plate.At the same time operators should install the electromagnet on the chain plate, in order to prevent debris entering into the crusher, damaging the hammer, lining plate and bearings.In addition, if there is any abnormal sound, the machine should be closed down.After identifying the cause of the malfunction and clearing the fouling in crushing cavity, the hydraulic cone crusher can be restarted.(3) human- made faults.
On the building industry of express highway, big amount of high quality sand and aggregate are needed.Dsmac european stone jaw crusher provides important equipment safeguard.European jaw crusher is suitable for crushing the mine ore, rock ore, slag, etc with compression pressure under 320mpa.The product crushing cavity adopt the structure of symmetrical "v" shape, which makes the feeding width accordance with the actual feeding width.Also it equips long wear resistant eccentric shaft, which is bigger than the same model and with more sealing effect as well as long lifespan of bearing.
The cost of purchasing granite crushers accounts for most of the investment.There are a lot of crushers for renting in the current market, but the crushers usually have low efficiency and high wear ratio.
