Want to buy a set of production lines for rice stone and 2-5 crushed stone. Is there any recommendation?
The production line for rice gravel and 2-5 crushed stone is generally the production line for normal stone production. It can be configured with: feeder + first breaking + second breaking + vibrating screen, etc.
Because the hardness of stone raw materials is different, the feeding size is also different, so the configuration also varies according to the situation.
Generally, after the stone is blasted and mined from the mountain, the jaw crusher is required for rough crushing, and the large stone is crushed to a medium particle size. The size of the outlet of the jaw crusher is generally 5-30 cm.
The materials after rough crushing can be sent to the second crushing - cone crushing or counterattack crushing for medium-term fine crushing, which can directly produce stones of different specifications such as 1-2, 1-3, 2-5 and 3-8, as well as some rice stones, melon seed slices, stone powder and other products.
As for the problem of cone breaking or counterattack breaking, it depends on the hardness of the stone. High hardness stones such as granite, basalt and tuff need to be equipped with cone breaking. The later wear will be relatively small and the maintenance cost will be lower. If you want to break low and medium hardness stones such as limestone and bluestone, you can use impact breaking, so the cost is lower.
If the raw materials have been roughly crushed and the size is not large, they can be directly crushed with the second crusher to produce stones that meet the particle size requirements.
