stone crusher manufacturers for sand, quarry, mining and construction
The types of pressure crushers include jaw crusher, roller crusher, and gyratory crusher. The pressure type crusher uses two hard parts of the machine to press each other to crush rock material. For example, the jaw crushers use the fixed jaw plant and movable jaw plate.
The jaw crusher's main function is to reduce the size of the raw materials or large pieces of material to a sufficiently small size, so as to facilitate the next step of the crushed material. In the quarries and mine materials crushing plant, it is generally used as a primary crusher. The types of jaw crushers are single toggle and double toggle. The construction of the single toggle jaw crusher is compact and simple, and the transmission components such as eccentric shafts are less stressed. Due to the vertical displacement of the movable jaw is small, the material is less excessively broken during processing. Therefore, the wear of the movable jaw plate is less.
Compared with the simple pendulum type, the double toggle type jaw crusher has the advantages of lighter weight, fewer components, a more compact structure and uniform crushing, high productivity. 20-30% higher productivity than a simple swing jaw crusher of the same specification.
Tooth Roller crusher is a new product that is designed and developed according to the structure principle of Gunlock crusher in America. The machine has the advantages of small volume, high crushing ratio (5-8) , low noise, simple structure, convenient maintenance, high productivity, even particle size of crushed materials, low over crushing rate, convenient maintenance, etc. The mall roller crusher is widely used in the mining industry as a secondary crusher.
Gyratory crusher is a new type of crusher that can replace fine jaw crusher and cone crusher. It consists of a concave surface and a conical head, both of which are usually lined with manganese steel. The inner cone has a slight circular movement but doesn't rotate. The gyratory has the advantages of good finely crushing effect, large processing capacity, small vibration, simple maintenance, low cost, and less lining plate wear.
Impact crushers crush materials by impact rather than by pressure. The material is broken in the crushing chamber under the impact force. It can handle materials with side length less than 100-500 mm, with compressive strength up to 350 MPA. It has the advantages of a large crushing ratio and cubic particles after crushing. There are two types of impact crushers: Horizontal Shaft Impact(HSI) Crushers and Vertical Shaft Impact(VSI) Crushers.
In the sand making plant is one of the essential crushers. Cone crusher according to the crushing force is divided into Simmons spring type and hydraulic type. Hydraulic type is divided into single-cylinder and multi-cylinder cone crusher. According to the rotary speed, there are three types: low speed, medium speed and high speed.
The basic structure of cone crusher is similar to that of rotary crusher, but the range is larger. It rotates and presses against the stone on the side of the machine, where it falls into the lower chamber and is crushed again until it falls out of the bottom. Its advantages: reliable structure, high productivity, easy adjustment, and low operation cost.
Hammer crusher(Hammer mill) is broken by an impact between a high-speed hammer and material. This type of crusher is divided into two types: single rotor and double rotor. Single Rotor is divided into reversible and irreversible. Hammer crusher is mainly composed of the rotor, spindle, hammerhead, lining plate and impact plate. And it mainly crushing for coal, salt, chalk, gypsum, brick, limestone and so on. It also used for crushing fiber structure, flexibility, and toughness of strong broken wood, paper, etc.
The advantages of the hammer: larger crushing ratio, high production capacity, uniform products, less over-powder phenomenon, simple structure, light equipment quality, simple operation, and maintenance.
Sand crusher is also called VSI crusher. It is an indispensable equipment for artificial sand manufacturing plant. VSI crusher imported advanced German technology development and production, with the international advanced level. Its performance plays an irreplaceable role in the fine crushing equipment of various materials. There are two types of sand-making machine: stone hit stone and stone hit steel.
The upper and lower hitting guard plate is installed on the crushing cavity wall of the sand making machine. It makes the ore material to be crushed by the impact, friction or high-speed impact between the material and the lining layer formed by the material and the material accelerated by the flywheel when accelerating. The materials do not come into direct contact with the equipment. This method reduces the wear and tear of fittings and prolongs the service life. "Stone hit stone" sand crusher is suitable for material with high abrasion above medium hardness, such as basalt. And the finished product has good grain shape, but the powder content is a little more. So it is more suitable for aggregate shaping.
In the crushing cavity wall of the sand-making machine, the lower hitting guard plate is replaced by the perimeter guard plate. When the ore material is thrown out by the roller, it is directly impacted on the guard plate for many times and the crusher. Under the constant impact, and then the crushing cavity material impact, ore material broken more fully, and the finished material particle size smaller. The "stone hit steel" sand crusher is suitable for small abrasive materials below medium hardness, such as limestone, and the crushing efficiency is high. However, due to crushing depends on the impact, so wear parts are higher. The finished product is slightly worse, it is more suitable for sand-making.

stone crushers cause huge pollution, unscientific mining degrades environment: ngt
New Delhi, Jul 2 (PTI) Observing that stone crushers cause huge pollution and such unscientific mining degrades the environment, the National Green Tribunal Friday formed a committee to look into a plea against their operation in Rajouri district in Jammu and Kashmir.
A bench headed by NGT Chairperson Justice Adarsh Kumar Goel constituted a joint Committee of Central Pollution Control Board (CPCB), state PCB and District Magistrate, Rajouri, to look into the grievances and ascertain the extent of non-compliances.
The bench said: It is well known that stone crushers have potential for huge pollution and unscientific mining for such stone crushers further degrades the environment. Statutory safeguards under the Environment (Protection) Act, 1986, Water (Prevention and Control of Pollution) Act, 1974 and Air (Prevention and Control of Pollution) Act, 1981 need to be followed and monitored by the statutory regulators.
Violations, being criminal offence under the law, there is need to take preventive and remedial action, including recovery of compensation on 'Polluter Pays' principle for the past violations till illegal activities are stopped.
The NGT said that based on verification by committee, the statutory regulators may take action to prevent further damage to the environment and assess and recover compensation for the past violations.
The compensation may cover not only the cost of mined material but also the cost of restoration and ecological services forgone forever, with element of deterrence. The guidelines laid down by the CPCB in this regard may be followed, the bench said.
The tribunal was hearing a plea filed by village sarpanch Arti Sharma against operation of stone crushers by M/s Diamond Stone Crusher, VPO Saranoo Tehsil, District Rajouri, J&K and M/s Shankar Stone Crusher, VPO Saranoo Tehsil, District Rajouri, J&K, in violation of environmental norms.
According to the applicant, the said stone crushers are located close to residential area and Tawi river. Illegal borewells have been dug for extraction of ground water. Requisite Environmental Clearance has not been taken. Illegal mining is also done on the bank of Tawi River, using heavy machinery.
Air pollution is caused by using vehicles for transportation. This is resulting in lowering of the water level, water scarcity, decreasing agriculture productivity, loss of biodiversity, land degradation, soil erosion, unproductive waste lands, noise pollution, dust pollution, water pollution, loss of habitat of flora and fauna, the plea said.
