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.

JXSC stone cone crusher machine is widely used in many sectors, such as mining, smelting, building materials, roads, railways, water conservancy, and chemical industries. Our stone crushers machine is suitable for primary, secondary and tertiary crushing. Cone crushers mainly divide into GP, HP and Symons series, compound, CS, HPC, sand, laboratory, propel cone, etc.

JXSC provides a high-quality rock crusher cone machine, like the brands of Mesto and Nordberg. We also have other series crushing machines, such as jaw crusher, impact crusher, hammer crushers and sand making machines.

The cone series crushers compress stone/rock mineral materials by squeezing force between the fixed shaft and moving shaft. Change the least gap between the two crushing shafts of the equipment can adjust the target particle size. When the wedge or eccentric rotator starts to work, compression comes into being within the cavity. As the rock materials move down, the chamber mouth becomes narrower, the material becomes smaller. The crushed materials discharge at the lowest of the machine once they through the chamber.

Cone crushing types of equipment are widely used in metal and non-metal mines, cement plants, sand and stone metallurgy and other industries. It is applicable to various ores and rocks with fine and fine Platt hardness 5~16, such as iron, granite, limestone, quartzite, etc. Its working principle is the same as that of the gyratory crusher, but stone crusher cone only for crushing medium or fine material. The uniformity of the discharge particle size of the medium and fine crushing operations is generally higher than that required for the coarse crushing operation. Therefore, there is must provides a parallel section at the lower part of the crushing chamber. At the same time, expediting the rotation speed so that the material is in the parallel zone and squeeze more.

The crushing of the medium-fine crushing operation is larger than coarse. Then the loose volume after the crushing has a large increase. In order to prevent the crushing chamber from causing clogging, it needs to increase the total discharge cross-section by increasing the diameter of the lower portion of the crushing cone. And without increasing the discharge opening to ensure the required discharge size.

The discharge opening of the cone crusher parts is small. It is easier to cause accidents if feeding the non-crushed material. Because the medium and fine crushing operations have strict requirements on the discharge size. It must adjust the discharge opening in time after the liner is worn, if not will damage the cone.

When the Simon-type spring safety rock crusher cone overload, the tapered housing forces the spring to compress and raise itself to increase the discharge opening, and discharge the non-crushed material. The adjustment of the discharge opening is via adjusting the sleeve. And the adjustment sleeve of the housing can be rotated to drive the housing to rise or fall by the thread on the outer circumference to change the size of the discharge opening. The secure and adjust of hydraulic cone crushers in the same way as a hydraulic gyratory crusher.

When the cone crusher is working, the rotation of the motor rotates by a belt pulley or a coupling. Some drive shaft and cone portion rotates under the urging of the eccentric sleeve. Therefore, the broken wall of the crushing cone is close to and sometimes leaves the surface of the rolling wall fixed on the adjusting sleeve. Then the ore is continuously subjected to impact, pressing and bending in the crushing chamber to realize the crushing of the ore. The motor drives the eccentric sleeve to rotate by the bevel gear, the crushing cone rotates. The crushing cone is close to and then leaves the fixed cone to complete the crushing and discharging. The joint between the support sleeve and the frame body is pressed by the spring. When the crusher falls into a non-breakable object such as a metal block. The spring is compressed and deformed to discharge foreign matter. Therefore achieving insurance and preventing damage to the machine.

When the tertiary cone crushers pass through the crushing chamber or the machine overload for some reason. The cone crusher spring insurance system realizes the insurance, and the discharge port increases. The foreign matter is discharged from the crushing chamber of the cone crusher. If the foreign matter is stuck in the ore, it can uses the clearing system to continues increase the output. The foreign matters discharge out. Under the action of the spring, the cone crush machine automatically resets the discharge port, and resumes normal operation. The surface of the crushing chamber cover with a wear-resistant high manganese steel liner. The size of the discharge port is adjusted by hydraulically or manually.

The name of the single-cylinder cone crusher is because it is supported by a hydraulic cylinder at the bottom to support its crushing force. Due to the high rigidity of the hydraulic medium, the load force of the crusher can be well supported. At the same time, the protection effect is better in overload protection, and the crushing force can be made larger. Improving the power factor, reducing the equipment and foundation. Facility investment. The hydraulic cone crusher is also better than the springs.

The single-cylinder crushing machines construction is relatively simple, and the feed size of the S-cavity cone crushers can be larger. The CC series single-cylinder cone crusher also has a relatively simple structure, easy to use and maintain. JXSC CC series single-cylinder crusher has been widely used in hydropower, nuclear power, highway, high-speed rail, stone, mining and non-metal mines, and has been fully recognized by users. Its performance is comparable to that of foreign mesto brands. Good equipment also needs good maintenance, so the machine needs to care. The working condition during the use process also determines the service life of the equipment. It is very important to always do the maintenance work on the equipment to ensure that the equipment works under normal working conditions. Due to the structure of the crushers, it should pay special attention to the problems of crowding the feed, the segregation of the feed, the drop of the feed, and the like. And minimizing the unnecessary impact to cause abnormal damage to the crushers.

The multi-cylinder cone crusher evolves from the original multi-spring cone crusher. The hydraulic instead of the spring has a better protection effect, and the crushing force can be made larger. Then it will more powerful and efficient. The hydraulic cone crushers are also better than the spring cone machine. However, the structure of the hydraulic cone crusher is relatively more complicated. The cost of one input is higher than that of the spring cone crushers.

Although single-cylinder and multi-cylinder are named according to the number of hydraulic cylinders, we cant simply understand that the construction of them is the same. There is a big difference between the two cones crusher. The multi-cylinder hydraulic cone has a broken load-bearing structure, and the main shaft is not as long as a single-cylinder hydraulic cone. The multi-cylinder hydraulic cone-breaking overload protection device locates outside the casing. There are multiple accumulators single or multiple safety valves If there is excessive iron or jam. Accumulator stamping, if the pressure continues to rise, the safety valve will relieve, the upper frame will rise. And the gap between the broken walls will increase, and the iron block or the stuck material will fall.
