Disadvantages of Cone Crusher

Disadvantages of Cone Crusher

The four fatal flaws of the cone crusher, how to solve it? See if your cone break has these disadvantages.

In modern beneficiation, cone crusher has become a widely used crushing equipment. Its crushing ratio is large, its efficiency is high, its energy consumption is low, and its uniform particle size makes it suitable for crushing hard or medium-hard ore. It is applied to medium and fine crushing operations in various black and non-ferrous metal crushing processes, effectively reducing the grinding grain size, achieving multiple crushing and grinding, improving the ball mill capacity and improving the economic benefits of the plant.

In the daily use process, due to the long-term use and the equipment itself, the cone crusher inevitably has certain drawbacks, which affects the normal production operation. This paper mainly introduces the four major disadvantages and improvement measures of the cone crusher.

Unreasonable dustproof device

Unreasonable dust-proof device, dust-proof water pipe is easy to block, and a large amount of dust enters the thin oil station, causing serious oil pollution. Therefore, the lubricating oil needs to be replaced frequently, and the contaminated lubricating oil is liable to cause damage to the oil pump. It can be changed to dry oil or water seal to prevent dust and impurities from entering the machine body, thus ensuring the cleaning of the lubricating oil, prolonging the service life of the sliding bearing and the thrust ball bearing, and making the machine operate normally.

Unreliable safety device

Unreliable safety devices make it difficult to clear the cavity. If the cone crusher is stuck and stopped, the crushing chamber will be filled with ore, and the funnel needs to be removed for manual cleaning, which seriously affects normal operation. Some manufacturers use spring-type protection device and lubrication system double insurance control, so that the cone crusher is protected during overload, greatly reducing downtime and good bearing lubrication.

Unreasonable cavity structure

Unreasonable cavity structure, limited fracture surface and low production efficiency. The horizontal drive shaft of the traditional spring cone crusher adopts a horizontal shaft copper sleeve, which has short service life, low rotation speed and high failure rate, so the output is low. Nowadays, the crushing chamber of many cone crushers adopts the principle of intergranular lamination crushing, which significantly increases the crushing ratio and output.

Long maintenance cycle and fragile spare parts

The maintenance cycle is long and the spare parts are vulnerable. The main wearing parts of the cone crusher are the moving cone lining and the fixed cone lining. Due to the complicated disassembly and assembly process and the troublesome filling with the filling, it is necessary to prepare the spare adjusting ring device and the spindle device. The moving cone liner can be thickened to extend the life, and high-strength materials are used in key components to increase the weight and enhance reliability.
