The high hardness ores mainly include granite, marble, basalt, iron ore, copper ore, etc. In addition, shale, metal ores, etc. are all high-hardness stones.

Wear-resistant crushing machinery is used for high-hardness stone crushing. The commonly used types are jaw crushers and cone crushers. There are two types of cone crushers: horizontal bar hydraulic cone crusher and multi-cylinder hydraulic cone crusher.

What is the technological process of producing stone from high hardness stone?

The production of high-hardness stones requires two processes of crushing and screening.

1.The crushing process is as follows: the large pieces of stone are sent to the jaw crusher through the feeder for coarse crushing, and then the crushed stone is sent to the cone crusher for fine crushing and crushed to the size of stones.

2.Screening process: Crushing is crushing large stones to the size of stones, and if you want stones of different sizes, you need screening equipment to complete them. The stone crushed by the cone crusher is sent to the vibrating screen through the conveying equipment. By setting the number of layers of the screen and the size of the screen hole, we can realize the production of different specifications.
