STONE CRUSHER

Crushed stone is segregated into various sizes like 35mm, 20mm, 12mm, etc for different uses. Crushed stone aggregates are used for construction of roads, bridges, housing, industril building construction and other cement based products like RCC pipes, PSC poles, premoulded slabs, frames and beems, etc for fabrication. It is advantageous if the crushed stone unit is set up near the quarries where the granite boulders of various sizes are available for the crushing unit. The wastage from the granite industry will be of much use ot the crushed stone unit.

Market：

Housing is a basic need of the society. Hence, it is receiving increased focus. All the building constructions whether it is housing or industrial construction activities requires crushed stone. Crushed stone is also required for cement based products like RCC pipes, PSC poles, cement concrete hollow blocks, precast cement concrete slabs, well rings, window & door frames and road laing. The demand for crushed stone will continue to grow with the growth of its user industry. The unit an be set up depending availaility of raw material and major commercial centre.

Manufacturing process:

The granite stones of various sizes are fed into the jaw crushers for size reduction. Depending on the desired output size of the crushed stone, the raw material may be fed to one or two jaw crushers in a sequence. Then these crushed stones re passed on to the rotary screen for size gradation. Material is handled through a belt conveyor to the different places of operation i.e from jaw crusher to the rotary screen.

Coal is common energy resource, and it is a combustible black or brownish-black sedimentary rock composed mostly of carbon and hydrocarbons. Coal, a fossil fuel, is the largest source of energy for the generation of electricity worldwide. Coal is extracted from the ground by mining, either underground or in open pits.

Natural coal must go through coal processing. In this process, coal crushing and coal milling is important.

Coal crushing Plant:

We need coal crusher to crush the coal into pieces, there are several types of coal crushers.

Jaw Crusher is mainly used to crush kinds of mining stones primarily, and the largest compression resistance of the material to be crushed is 320MPa. The jaw crusher is widely used in mining, metallurgical industry, building material, highway, railway, and chemical industry.

Impact Crusher is the world's widely used crusher, for mineral processing, chemical, cement, construction, refractories, ceramics, glass and other industrial sectors in the broken and broken bits for a variety of medium hardness materials. My company’s product of Crusher is a combination of domestic and foreign sand and gravel mining industry , the specific conditions developed, the latest generation of Impact Crusher. Their product’s size can be adjusted, broken standard variety. The family of devices can dealing with the material with the side length 500mm, not more than 350Mpa anti-pressure strength, is an ideal aggregate processing equipment in the senior road surface and hydropower building.

Cone crusher is suitable to crush various kinds of ores and rocks of medium or above medium hardness. Compare with jaw crusher, cone crusher is of stable structure, high efficiency, easy adjustment, and use economically, etc. The spring safety system of crusher acts as an overloading protection system that allows metals to pass through the crushing chamber so as not to damage the cone crusher.

These coal crushers are not used lonely, general we compose these crushers into a complete coal crushing plant with screening machines and belt conveyor.

Iron is the raw material for making steel, about 98% of iron ore is used to make steel, While the other uses for iron ore and iron are only a very small amount of the consumption. In nature, two major minerals in the production of iron are it's oxides, hematite and magnetite. These are found in preCambrian iron formations. Historically there was also production from goethite and siderite. The iron sulfides (pyrite and pyrrhotite) were not used as iron sources due to the difficulty of removing sulfur from the metals and the brittleness this sulfur caused in the metal. Major producers of iron ore include Australia, Brazil, China, Russia, and India.

Powdered iron: used in metallurgy products, magnets, high-frequency cores, auto parts, catalyst. Radioactive iron (iron 59): in medicine, tracer element in biochemical and metallurgical research. Iron blue: in paints, printing inks, plastics, cosmetics (eye shadow), artist colors, laundry blue, paper dyeing, fertilizer ingredient, baked enamel finishes for autos and appliances, industrial finishes. Black iron oxide: as pigment, in polishing compounds, metallurgy, medicine, magnetic inks, in ferrites for electronics industry.

So we first crush the iron ore using iron ore crusher. There are several type of iron ore crusher, such as jaw crusher, cone crusher, impact crusher etc. There crushers can compose a complete iron ore crushing plant. We can choose different iron ore crusher, then the capacity of the complete crusing plant is different.

Iron ore crushing process:

Firstly: iron ore enter into jaw crusher for primary crushing, then into the impact crusher for secondary crushing, the final crusher is cone crusher. The small iron ores after crushing can be screened out through screening machine, the unsuitable iron ore return to the iron ore crushing plant for crushing again.

Stones is the essential buiding materials. Natural stones usually are big, so we must crush them into small pieces. Stone quarry uses stone crushing plant to make aggregate for construction.

Stone crushing process :

Big materials are fed to the jaw crusher evenly and gradually by vibrating feeder through a  hopper for primary crushing. After first crush, the material will transferred to impact crusher  by belt conveyor for secondary crush; the crushed materials will then transferred to vibrating  screen for separating. After separating, the parts that can meet standard will be transferred  away as final products, while the other parts will be returned to impact crusher, thus forming a  closed circuit. Size of final products can be combined and graded according to customers  specific requirement. We can also equip dust catcher system to protect environment.
