What is the difference between fine crushing and coarse crushing of cone crusher

Cone crusher, we are all familiar with, is a kind of crushing machinery for raw materials in metallurgy, construction, road building, chemical and silicate industries, commonly used in various hardness of ores in the medium crushing and fine crushing processing, in addition, it is also possible to carry out coarse crushing processing, so what is the difference between fine crushing and coarse crushing of cone crusher?

Cone crusher has always been in line with the development of the times, comprehensive customer's actual needs, and constantly improve the technology, according to the different working principles and different product particle sizes, is divided into four models, there are dozens of models, including fine crushing and coarse crushing, in the crushing granularity, the purpose of the operation, the application scenarios, dust removal and the structure of the difference.

Cone crusher has three types of cavities, which are coarse, medium and fine crushing cone crusher. Short head type, with longer parallel belt, obtains smaller product size, suitable for fine crushing. Standard type, the parallel belt is shorter, the obtained product size is larger, suitable for coarse crushing.

1. Crushing granularity

Fine crushing: the material after coarse crushing is further crushed into finer particles, the crushing size is obviously smaller than coarse crushing.

Coarse crushing: mainly used for the initial crushing of large materials into smaller particles, relatively large crushing size.

2. Purpose of operation

Fine crushing: more focused on improving the fineness and uniformity of the material to meet the fine requirements of specific industries on the size of the material.

Coarse crushing: the main purpose is to reduce the volume of materials, to facilitate subsequent processing and transport, through coarse crushing, large ores or raw materials can be broken down into smaller pieces for the convenience of subsequent processes.

3.Application Scenario

Fine crushing: more often used in areas that require high precision control, such as chemicals, ceramics, etc., to ensure product quality and performance.

Coarse crushing: usually used to deal with large, hard materials, widely used in mining, construction and other industries.

4. Dust removal difference

Coarse crushing cone crusher adopts dry dustproof device; fine crushing cone crusher uses water seal dustproof device.

5. Structural differences

Coarse crushing: the two conical shapes are sharply inclined, and the movable cone is upright.

Fine crushing: the fixed cone is an inverted truncated cone, the structure is different to adapt to the needs of finer crushing.

Fine and coarse crushing cone crusher has 5 models, hourly output of 12-700 tonnes, feed size ≤ 300mm, discharge opening width of 3-60mm, according to the need for a reasonable choice, the specific cone crusher model parameters can be clicked on the website customer service immediately free of charge consultation.
