How to select bluestone processing equipment? What is the bluestone processing workflow?

China possesses abundant bluestone resources. After crushing and processing, bluestone can be manufactured into aggregates of various specifications, such as 12 and 13, thereby enhancing its industrial and economic utility. So, what machinery is used to process bluestone aggregates of 12 and 13 specifications? What is the specific production process for stone aggregate processing?

Bluestone Aggregate Crushing Equipment

Recommended Bluestone Crushing Equipment

1. Impact Crusher

The impact crusher employs a triple impact plate structure, increasing the number of impacts on the material while reducing hard compression and friction, thereby extending the service life of wear-resistant components. Its impact-based working principle produces uniform, cuboid-shaped particles with minimal needle-like or flaky material, ensuring high-quality finished products. The gap between the impact plate and hammer plate is easily adjustable, effectively controlling output particle size. Material smaller than 35mm can be screened to produce bluestone aggregates meeting 12mm and 13mm specifications.

2. Cone Crusher

The cone crusher employs a layer compression crushing principle. Its wear parts, crafted from high-manganese steel, make it an ideal choice for processing highly abrasive materials. This equipment is suitable for crushing high-hardness materials such as quartzite, pebbles, and granite. The cone crusher incorporates advanced features including iron overload protection, automatic hydraulic chamber cleaning, and automatic lubrication. It can meet diverse production requirements while helping to reduce labour and maintenance costs by over 30%.

3. Hammer Crusher

The hammer crusher performs primary and secondary crushing in a single operation, eliminating the need for additional primary crushing equipment and significantly reducing investment costs. It is particularly suited for processing medium-to-low hardness and brittle materials such as limestone, coal, cement clinker, and glass. The hammer crusher allows free adjustment of discharge particle size, produces well-shaped output, and operates with energy efficiency and low consumption, making it the preferred choice for users.

Green Stone Processing Production Flow

Scheme One: Feeder + Jaw Crusher + Impact Crusher/Cone Crusher + Conveyor

Primary Crushing: Large stones are uniformly fed by a vibrating feeder to the jaw crusher for primary crushing.

Medium-Fine Crushing: Crushed stones are conveyed via belt conveyor to the impact crusher or cone crusher for further reduction.

Screening: Finely crushed stones are transported by belt conveyor to the vibrating screen, separating them into several specifications. Stones meeting size requirements are directed to the finished product stockpile, while undersize material is returned to the crusher for reprocessing, forming a closed-circuit loop.

Scheme Two: Feeder + Hammer Crusher + Conveyor

With the aid of a feeder, bluestone enters the hammer crusher where it is broken by high-speed impact from hammers. The crushed material is screened through bars; particles smaller than the bar spacing are discharged directly, while larger material undergoes multiple impacts and grinding until the required size is achieved. This configuration is particularly suited for artificial sand production and aggregate shaping in construction, motorway, railway, and municipal engineering sectors.

As a premium construction material, bluestone finds extensive application in motorways, high-speed railways, and building projects. Through judicious selection and configuration of crushing equipment, the economic and industrial value of bluestone can be optimally realised.
