zkj/ Release time : 2023-07-10

Crusher is one of the essential core equipment of sand and gravel production line, which not only determines the capacity size of sand and gravel production line, but also the quality of finished sand and gravel products. So how do we choose the coarse crusher when the raw material is initially crushed?

Crusher use scenario:

In choosing crusher, should look at the use of the equipment scene is not to meet their needs, the market crusher equipment, mostly used in sand and gravel quarries, mining, coal mining, concrete mixing plant, dry mortar, power plant desulfurization, quartz sand and other fields.

Crusher application raw materials:

When choosing a crusher, you need to look at the application of raw materials is not to meet their own requirements. For example, river stone, granite, limestone, iron ore, limestone, quartzite, pyrochlore, iron ore, gold ore, etc.. And the hardness of different kinds of materials is different, the greater the hardness, the higher the crushing difficulty. For crushing hard or medium hard ores, you should choose Jaw Crusher as the primary crushing equipment, and for crushing medium hard or soft ores, you should choose cone or impact crusher.

Crusher discharge size and output:

When choosing a crusher, we should pay attention to the crusher's inlet and outlet size and output. This is because different equipment has different equipment parameters. If the feed size is large, but the discharge size is small, it is necessary to use secondary or multi-stage crushing, and if the ore feed size is small, multi-stage crushing is generally not required. If the customer's production output requirements are larger, the larger the crushing plant specifications and models required, the more capital investment and output of the production line will increase. If the material in the crushing material is larger than the size of the discharge port or the width of the feed port, the ratio of the particle size of the material before and after crushing will be larger, and the crushing ratio of the crusher will be increased, which will lead to the lower productivity of the crusher, on the contrary, if the crushing ratio is small, the productivity of the crusher will be increased accordingly. How to choose the specific you can check the website, such as jaw crusher, you can also directly consult the online customer service, send you a coarse crushing crusher equipment parameters.
