Characteristics and structure of cone crusher

Cone crusher is a kind of crushing machine suitable for raw materials in metallurgy, construction, road construction, chemical and silicate industries. According to different crushing principles and different particle sizes of products, they are divided into many models. Crushers are widely used in mining, smelting, building materials, highways, railways, water conservancy, chemical industry and many other departments. The cone crusher has the advantages of large crushing ratio, high efficiency, low energy consumption, and uniform product particle size. It is suitable for medium and fine crushing of various ores and rocks. The models are mainly divided into SMG series, spring type and HPC series. Their working principle and structure are introduced respectively. The development history, working principle, composition, influencing factors, technical advantages, operation matters, common faults, inspection and maintenance of cone crusher are also introduced in detail.

Characteristics and structure

With the continuous development of mining technology, cone crushers are also divided into several types, including spring cone crusher, roller cone crusher, hydraulic cone crusher and composite cone crusher; According to the model, it is divided into ordinary py cone crusher, Simmons cone crusher, composite cone crusher, standard hydraulic cone crusher, single cylinder hydraulic cone crusher and multi cylinder hydraulic cone crusher. The hydraulic crusher is developed on the basis of digesting and absorbing various types of cone crushers that have reached the international advanced level in the 1980s. It is obviously different from the traditional cone crusher in design, and integrates the main advantages of various types of cone crushers known so far. It is suitable for fine crushing and ultra-fine crushing of hard rocks, ores, slags, refractories, etc.

Structure introduction of cone crusher: the structure of cone crusher mainly includes frame, horizontal shaft, moving cone, balance wheel, eccentric sleeve, upper crushing wall (fixed cone), lower crushing wall (moving cone), hydraulic coupling, lubrication system and hydraulic system.

Machine composition

Hydraulic system

The hydraulic system is used to adjust the size of the ore discharge port of the crusher, and the hydraulic system can effectively ensure the safe operation of the equipment. When there is foreign matter in the crushing chamber, the hydraulic system can make the moving cone retreat automatically. When the foreign matter is discharged, the system will make the retreating moving cone reset automatically.

Crushing cavity

Broken cavity refers to the geometric space formed between the moving cone and the fixed cone. The shape of the crushing chamber has a great influence on the performance of the whole machine. Crusher cavity is the main technical index of crushing. From coarse crushing to fine crushing, the machine has four specifications of cavity, and it has six possible combinations, which means that it can best meet the special requirements of users.
