QUARRYING EQUIPMENTS

Stone Quarrying Line

After international financial crisis, the railway construction investment was put on an unprecedented level as an important means of stimulating domestic demand. Railway construction has entered into a summit; a large number of the stone production lines are put into operation. Therefore, a large number of quarry equipment is highly demanded.
Quarry production process
First, quarry stone from the stone field is separated from the quarry face by blasting. Then, quarry stone is transported to the rock field. Through a series of crushing machine, screening equipment, the stone is crushed, screened into different size windrow. In this process, we must ensure that productivity meet the requirements, and reduce needle flaky particles while producing cube-shaped aggregates that meet specified size. For saving energy, reducing workman and machine maintenance, and expand equipments life span, it is better to reduce the maximum size of input material, to reduce congestion and blocking when feeding, and to exclude hard broken materials.
Stone crushing process
In the quarry production process, the stone crushing is very important. It is related to the final product. Here is the details.
The composition of stone crushing line:
Stone production line is consist of the vibrating feeder, jaw crusher (coarse crushing), Impact Crusher (secondary crushing), vibrating screen, belt conveyor etc.

Stone production line equipment configuration is based primarily on stone specifications, capacity and application of final products. We provide pre-sale, in-sale and after-sale services and strive for the customer to design the most rational and economical crushing plant based on customer production site.

Stone crushing line process:
Large stone through the hopper are evenly sent by the vibrating feeder to jaw crusher for broken. After the first broken, the stone through the belt conveyor are sent to impact crusher for further broken. Then different types of stone are screened out by vibrating screen. Stones that meet the size requirements are sent to the finished windrow through conveyor belt, while those that do not meet requirements are sent back to impact crusher to crush again. Finished size can be adjusted and graded in accordance with the needs of users. Being equipped with auxiliary dust deducing equipment, the crushing plant is more environmental-friendly.

The performance characteristics of stone production line:
Stone production line is highly automated with low operation cost, large capacity, and high-yielding. The final size has even particle size and grain shape that meet the requirement of national high-speed material and can be adjusted.
Application of new quarry equipment:

With the development of various projects, in the highways, railways, high-rise buildings, hydropower station and other constructions, sand and gravel aggregate grain shape, size distribution has been brought up a very high demand, especially basalt. VSI (Vertical Shaft Impact) Crusher is the necessary equipment that produces high-performance concrete (C40 and above) Aggregate (gravel). After the shaping Needle flake of stone is not more than 5%, and can fully meet the technical requirements in the production of these special industries with high-performance concrete (C40 ~ C80) aggregate. Equipped VSI with HPC hydraulic cone crusher, PF Hard Rock Impact Crusher, PE Deep Cavity Jaw Crusher as well as assistant equipment like screen, washer etc. ,we design new technology for sand and gravel crushing and screening which can be applied to high-speed (high-grade) road, high-speed railway, hydropower stations, high-rise buildings, airport runways, ports, municipal engineering and other industries. VSI is now new quarry equipment widely used to meet different customer needs.
