In modern ore dressing, cone crusher has become a kind of crushing equipment with a wide range of applications. Its advantages of large crushing ratio, high efficiency, low energy consumption, and uniform product size make it suitable for crushing hard and medium-hard ores, so it is widely used. It is applied to the medium and fine crushing operations in the crushing process of various ferrous and non-ferrous metals, which effectively reduces the particle size of the grinding, realizes more and less grinding, and at the same time improves the capacity of the ball mill and improves economic benefits.
In the process of daily use, due to long-term use and the factors of the equipment itself, the cone crusher inevitably has certain drawbacks, which affect the normal production operation.
1. Long maintenance period and vulnerable spare parts
The maintenance cycle is long and spare parts are vulnerable. The main wearing parts of the cone crusher are the moving cone liner and the fixed cone liner. Because the disassembly and assembly process is more complicated, and the filling is more troublesome for pouring, it is necessary to prepare a spare adjusting ring device and a spindle device. The movable and fixed cone liner can be thickened to prolong the service life, and the key components are made of high-strength materials to increase the weight appropriately and enhance the reliability.
2. Unreliable safety device
Unreliable safety devices make it difficult to clean the cavity. If the cone crusher is stuck and s*ped, the crushing cavity will be full of ore, and the funnel needs to be removed for manual cleaning, which will seriously affect normal operation. Some manufacturers use spring-type protection device and lubrication system double insurance control, so that the cone crusher is protected when overloaded, *ly reducing the downtime, and has good bearing lubrication.
3. Unreasonable dustproof device
Unreasonable dust-proof device, dust-proof water pipe is easy to be blocked, and a large amount of dust enters the thin oil station and causes serious lubricating oil pollution. Therefore, the lubricating oil needs to be replaced frequently, and contaminated lubricating oil can easily cause damage to the oil pump. You can switch to dry oil or water seal to prevent dust and impurities from entering the body, so as to ensure the cleanliness of lubricating oil, extend the service life of sliding bearings and thrust ball bearings, and make the machine run normally.
4. Unreasonable cavity structure
Unreasonable cavity structure, limited crushing surface and low production efficiency. The horizontal transmission shaft of the traditional spring cone crusher adopts horizontal shaft copper sleeve, which has short service life, low speed, high failure rate, and low output. At present, the crushing cavity of many cone crushers adopts the principle of intergranular lamination crushing, which significantly improves the crushing ratio and output.
