Introduction
Stone crusher plant is used to produce aggregate of limestone, granite, basalt, river stone, marble, iron ore, dolomite, quartz, slag etc. It is widely applied for hydraulic power, construction, highway, railway, airport runway, civil engineering projects, etc.
1. This stone crusher plant is mainly applied to medium or over-hard ores and stones, such as granite, iron ore, marble, etc. Its capacity can be 20-30 tons per hour, final aggregates size can be 0-10,10-20,20-30,30-40mm(changeable)
2. Primary jaw crusher is equipped with enhanced jaw plates and has high reduction ratio. Main frame and flywheels use thicker steel plate; We apply impact crusher,cone crusher or jaw crusher as the secondary crusher.(optional)
3. Water pipe or other washing equipment are equipped to clean the finished products.(optional)
4. Tertiary crusher(VSI )sand making machine or others may work as additional processing machines to diversify the final products. Tailor-made dust catcher or dust cover can also be applied to this plant.(optional)


Application
Stone crusher plant make use of a large range of equipment, such as intake hopper vibrating feeder or pre-screener, crushing unit(such as jaw crushers, impact crusher, heavy type hammer crusher, and cone crusher etc), vibrating screen, loading belt conveyor and other needed machines(dust suppression system, sprinkler system, dust remover machine etc)
Stone Production Line is usually decided by several factors:


Process of the stone crushing line
Big size stones are transferred to primary crusher through vibrating feeder from hopper for first crushing, then the crushed materials are transferred to impact crusher through belt conveyor for secondary crushing. The materials crushed will be transferred to the vibrating screen, and separated to different sizes. The aggregate with suitable size will be transferred to the final product pile and aggregate with unsuitable size will be transferred to the impact crusher for re-crushing. This forms a closed and manifold cycles. The sizes of final products will be graded and separated according to customers' requirements, and the duster will be attached for the sake of environment protection.


Stone Production Line is usually decided by several factors
1) Raw materials to be crushed.
2) The hardness, percentage of Si, moisture percentage of the raw materials.
3) The average size of the raw materials before entering into the crushing system.
4) Requested product sizes, percentage of the sizes, and their usage.
5) Crushing capacity per hour for this whole line.

Features
Smart structure to save the space and reduce the site area of the project.
The basement of the plant is smaller and can be set up quicker.
All the units are assembled in the factory, so it can shorten the installation time at working site.
The coordination of the plant is harmonious and high efficiency.
Easy installation and quick maintenance.
The crushing and screening plant is easy to disassemble and reinstall, all it can ensure that the machine can be moved and combined quickly according to the requirements of the project.
All the standard crushing and screening plant can be shipped in standard containers.


How to crush the granite with high efficiency?
Crush granite Not suitable use principle of "iron hitting stone", if use hammer crusher to crush it, Only to cause destruction to both sides internecine.the life of the hammer head and mechanical are not long. use intergranular laminated principle to crush granite, it make the most of the granite to realize the phenomenon of "stone hitting stone" in crushing cavity,  to replace the traditional single grain crushing principle, it realize the selective crushing of material,  increased the proportion of fine material products and the cube content,  largely reduced the needle flake material, while reduce wear of wear parts.
