Double vibrating feeder structure is very simple and we strengthen the wear parts, increasing the service life greatly. To the jaw crusher, we adopt heavy movable jaw and optimized connect methods, in this way, the hard mining ores can be crushed easily.

Obviously, jaw crushers are just primary crushers, they can crush big lumps to small lumps, but the products output size is still bigger than customers’ requirements. So when material discharged from the bottom of the jaw crusher, they are transported to one transfer station by belt conveyors. Under the transfer station, there are two units electric vibrating feeders, they feed the crushed lumps to belt conveyor steadily.

Then the lumps will be fed to the cone crusher. Double has two series cone crusher for sale in South Africa, one is HP series hydraulic cone crusher and another one is S series cone crusher. Here considering the budget, we suggest customer using two set S series cone crushers. By using this type cone crusher, customers can crusher mining ore aggregates to small particles easily.

For example, mining ore lumps can be crushed to 0~5mm, 5~10mm, 10~20mm or 0~1/8”, 1/8”~1/4”, 1/4”~1/2”, 1/2”~3/4” and 3/4”~1”. These size ranges well satisfy the world’s customers’ commonly requirements. Particles outputted from cone crushers are mixed with each other, to separate the different sizes particles, Double vibrating screens are necessary. The wire meshes are changeable, so producers just need to change the wire mesh if they need produce different size products. Finally, the qualified ones are conveyed to the store pile sites and oversize ones are transported to the cone crushers for crushing again.

It’s important to keep structural costs down, to design for ease of maintenance and operation, and to combine best practices with advances in fabrication and erection.

Best installation for crusher plant

In mining operations, the layout of crushing plants and ancillary equipment and structures is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum.Since the crushing plant’s structure and enclosure can represent the largest single cost element in a primary crushing plant, it is imperative to optimize these structural and construction costs to suit the life of the operation.

The fundamental goal for the design of a crushing plant is an installation that meets the required production requirements, operates at competitive cost, complies with today’s tough environmental regulations, and can be built at a reasonable price despite the rising costs of equipment, energy and construction labor.

Basalt dressing plant

Basalt can be a dark-colored, fine-grained, igneous rock composed generally of plagioclase and pyroxene mineral deposits. It most commonly forms as a possible extrusive rock, such as a lava circulation, but can also kind in small intrusive systems, such as an igneous dike or possibly a thin sill. It has a composition comparable to gabbro.

Basalt is most frequently crushed by basalt killer and grinding machines for use just as one aggregate in construction jobs. Crushed basalt is used by road base, concrete aggregate, asphalt pavement aggregate, railroad ballast, filter stone in drain fields and will other purposes. Basalt is also cut into dimension stone. Thin slabs of basalt usually are cut and sometimes rubbed for use as ground tiles, building veneer, monuments and other gemstone objects.

To one complete basalt beneficiation production line,it may contain many of the machines.The final equipments configuration depends the practical demands and the design.

Basalt Beneficiation Flow

When blast or digged out from the underground or from the mountain, the excavator carry the basalt to the basalt crushing site and feed dump the raw basalt mining to the hopper. Then the vibrating feeder under the hopper feed the raw material to the basalt crushers. Usually the crushed aggregates size is 0~10mm when the basalt discharged from the basalt crushers and classified by the vibrating screens.

The the basalt grinding machines (such as the ball mill) will grind the basalt aggregates to sand size or smaller particles. After classified and cleaned by the spiral classifiers, the particles will be fed to the basalt flotation machines or concentrator table. Then the concentrator, filter and dryer will thicken and .dry the particle and high purity available mineral is produced. In the beneficiation process, dense separation is usually adopt one time concentrating process and the producer will sell it after that for low production cost.
