What Are The Crushers For Hard Rock Granite

Last Update:2020-05-07 11:56:37

1、 Physical properties of granite:

Granite is a relatively hard rock with compressive strength greater than 30MPa. For this kind of rock, the raw material to finished product processing is generally processed by coarse crushing, medium fine crushing and forming process. In this paper, the configuration of granite crushing and processing production line is briefly described, which is also applicable to basalt, diabase, andesite and other materials that are difficult to break or have high crushing cost. According to the required product fineness, general materials can be divided into three types of technological processes: coarse crushing and medium crushing, coarse crushing and medium crushing plus fine crushing or coarse crushing and medium crushing and then fine crushing and shaping into molding materials. Generally, the shape of sand and stone particles treated by the shaping machine is better.

2、 What equipment does granite crushing production line need?

(2) Medium crushing stage: impact breaking is generally applied to the secondary crushing in the stone crushing process; the main crushing is less than 500mm, the compressive strength is less than 350Mpa, and the material after impact breaking is cubic grain; it should be noted that impact breaking can also be used as the first crushing process for the material with small feeding.

3、 Granite crushing process:

(3) Medium and fine crushing stage: cone crusher uses lamination crushing principle, with reliable structure, high crushing efficiency, easy adjustment and other characteristics, mainly used for crushing 13-369mm ore materials; As for the problem of cone breaking and counter breaking, it is often used in the second crushing process of the crushing line, and it can also be used as the first crushing process of the crushed stone production line for the material with small feeding. However, the feed size of cone crusher is generally smaller than that of impact crusher.

Granite is transported to jaw crusher through conveyor and vibrating feeder for first crushing. After coarse crushing, the materials are transported from conveyor belt to cone crusher or impact crusher through screening for secondary crushing. After medium and fine crushing, the circular vibrating screen is used for screening, and the larger particles are returned to the cone for crushing again. The materials that meet the requirements will enter the sand making machine for further crushing and shaping. If the materials need to be cleaned, they can be sent to the sand washing machine for cleaning. Finally, to meet the requirements of packaging materials classified according to different size ranges.

The equipment configuration problem of granite crushing production line is mainly determined by the user's specification of stone, the required output and the use of stone. According to the configuration management process of stone production line, there are different models of crusher equipment, different models correspond to a different production capacity of stone production line, feed particle size and discharge particle size, so we should follow our own stone specifications In order to get a reasonable and economic production line, the corresponding crushing equipment should be selected according to the influence of the output and the stone processed.
