A cone crusher is crushing equipment used in mining and construction industries. It crushes ore into stones of different particle sizes mainly through the squeezing action between the moving cone and fixed cone. Widely applied in metallurgy, chemical engineering, building materials and other fields, it is especially suitable for handling hard materials such as granite and basalt. It features a large crushing ratio, good product particle shape and low energy consumption.
### How to choose common types
The mainstream cone crushers on the market are mainly divided into two categories: spring type and hydraulic type. Hydraulic cone crushers are further split into single-cylinder and multi-cylinder models. Selection shall be determined according to material hardness and output requirements.
**Spring cone crusher**: It has a relatively simple structure and low cost, suitable for small and medium-sized production lines. However, manual reset is required after iron passing protection, leading to slightly troublesome maintenance.
**Single-cylinder hydraulic cone crusher**: Adopting a single hydraulic cylinder at the bottom, it integrates discharge opening adjustment, iron passing protection and cavity clearing functions. With high automation, it is applicable for secondary and fine crushing operations.
**Multi-cylinder hydraulic cone crusher**: Equipped with a multi-cylinder hydraulic system, it delivers greater crushing force. It is suitable for processing high-hardness rocks and produces finished materials with better particle shape, commonly used for high-standard aggregate production.
**Overseas perspective supplement**: In the international market, the selection between single-cylinder and multi-cylinder models focuses more on the feed limits and output requirements of specific models rather than simply the cylinder quantity. Some advanced machines have integrated remote monitoring and digital services.
