In the daily use process, due to the long time use and equipment itself factors, cone crusher inevitably has some drawbacks, affecting the normal production operation. This paper introduces four common shortcomings and improvement measures of cone crusher.
Unreasonable dustproof device, dust-proof pipe is easy to plug, a large amount of dust into the oil station, causing serious pollution of lubricating oil. Therefore, the lubricating oil needs to be replaced frequently, and the contaminated lubricating oil can easily lead to the oil pump damage. It can be changed to dry oil or water seal, so that dust impurities can not enter the body, so as to ensure the cleanliness of lubricating oil, prolong the service life of sliding bearings and thrust ball bearings, and make the machine run normally.
Unreliable safety devices make it difficult to clear the cavity. If the cone crusher is stuck and stopped, the broken cavity will be filled with ore, and the funnel must be removed for manual cleaning, which seriously affects the normal operation. Some manufacturers use spring protection device and lubrication system double insurance control, so that the cone crusher in overload protection, greatly reduce the downtime, and have good bearing lubrication.
3, Unreasonable cavity structure
Unreasonable cavity structure, limited broken surface and low production efficiency. The traditional spring cone crusher adopts the horizontal shaft copper sleeve with short service life, low rotational speed, high failure rate and low output. Nowadays, many cone crushers adopt intergranular laminated crushing principle to increase crushing ratio and yield.
4, Long maintenance period, spare parts vulnerable
Long maintenance period, spare parts vulnerable. The main wear and tear parts of cone crusher are moving cone lining and fixed cone lining. Because of the complexity of disassembly and assembly process and the trouble of filling material pouring, it is necessary to prepare the spare adjusting ring device and main shaft device. The dynamic tapered liner can be thickened, and the life is prolonged, and the key parts are made of high strength material, which can increase the weight properly and enhance the reliability.
