1 adjustable fine crusher the adjustable fine crusher mainly consists of a rotary part, guard plate, crushing chamber.The latest fine crusher equipped with a hydraulic device can be very convenient to maintain, save time cost.2 jaw crushing type jaw crusher, is the first choice for primary crushing equipment, with large crushing ratio, uniform product size, simple structure, the relatively small volume can be installed in the tiny space, etc.Therefore, it is widely used in mines, metallurgy, construction material, water conservancy and chemical industries.Compared with cone crusher, jaw type crusher has less investment, less finished flake and lower production cost.Compared with hammer crusher, the wear resistant parts have longer service time, high production efficiency and fewer maintain fees.The common jaw crusher has single toggle type and double toggle type, the former one also called as simple swing crusher, the latter one is called as complex swing crusher.3.Gyratory crusher the gyratory crusher is a large scale crushing machine which uses the gyratory movement of the crushing cone in the crushing cavity to extrude, squeeze and bend the materials.When the shaft sleeve rotates, the crushing cone is moving in eccentric around the center line of the machine continuously.The productivity of gyratory crusher is higher than that of jaw crusher.There are two types of discharging material and overload insurance, one is mechanical type, by adjusting the nuts on the top of the main shaft to lift up or down the crushing cone, thus change the discharge outlet width, and by cutting the safety pin on the driving pulley to stop overload.Another way is hydraulic gyratory crusher type, by changing the plunger under the hydraulic oil volume can adjust the crushing cone position, thus changing the size of the discharge port.4 cone crusher cone crusher widely used in the metal and mon-metal mines, cement, sand & gravel, aggregate, quarry, metallurgy and other industries.It is suited for fine crushing all kinds of ores and rocks with hardness 5 ~ 16, such as iron ore, non-ferrous metal ore, granite, limestone, quartzite, sandstone, cobblestone, etc.The working principle of cone crusher is the same as that of gyratory crusher, but it is only suitable for medium-sized crushing or fine crushing.The requirements of uniformity of particle size distribution in medium and fine crushing operations are generally higher than that in the coarse crushing operation.Therefore, a section of the parallel zone should be set at the lower part of the crushing cavity.In addition, the rotating speed of the crushing cone should be accelerated so that the material can be squeezed more than once in the parallel zone.The crushing of fine crushing operation is larger than that of coarse crushing operation, so the loose volume after crushing increases greatly.In order to prevent the crushing chamber from blocking, the total discharging cross section must be increased by increasing the diameter of the lower part of the crushing cone without increasing the discharging opening to ensure the required discharging granularity.When the simon spring safety cone crusher overloads, the cone-shaped shell forces the spring to compress and raise itself in order to enlarge the discharge port and discharge the non-broken material.The adjustment of the discharge opening is carried out by the adjusting cover, and the adjusting cover fixed with the shell can be rotated to drive the shell up or down by the thread on the outer circle, so as to change the size of the discharge opening.The safety and adjustment mode of hydraulic cone crusher is the same as that of hydraulic gyratory crusher.Maintenance of cone crusher 1, ensure full load production, avoid too coarse product granularity.2, optimize the cone crusher productivity by setting reasonable crushing ratio.3, it is necessary that equipped with an iron removal device.4, the spring cannot be too heavy pressured, the large pressure may occur shaft broke, light pressure may cause spring vibrating, influence the crushing efficiency.
The fixed jaw crusher (also called concrete crusher)is generally used in primary crushing, during whichlarge materials would be crushed to be suitablefor secondary crushing equipment like hydraulic conecrusher machine, impact rock crusher,rollercrusher.Since feeding sizeof secondary crusher is generally small, a large-sized stone must be resized by fixed jaw crusher at first.The impact rock crusher for sale is generally used in secondary or tertiary crushing.It is suitable to crush materials like granite, marble, etc.Materials with high hardness are not suitable for impact crusher since they will damage the easy-wearing parts during the crushing process.Impact crusher, whose finished product is in cubic shape without tension and crack, can crush all kinds of coarse, medium and fine materials (granite, limestone, concrete, etc.) with feeding size less than 500mm and compressive strength not more than 350mpa.Whats more, the discharging size can be adjusted and the crushing specification is various.
It's a complicated process to choose a suitable manufacturer and purchase a reasonable crusher.Customers should make a preliminary selection according to his actual situation and the above contents.The specific selection should also consult the engineer of the industry for a comprehensive analysis so that to maximize the profits.
Henan hongxing machinery co., ltd.Is a high-tech mining machinery and equipment produced in the factory, pe jaw crusher equipment produced, jc european version of the jaw crusher, the pf impact crusher, the pfw european version of the crusher, cs symons cone crusher, hpc hydraulic cone crusher, mobile crusher station, as well as grinding equipment, raymond mill, ultrafine mill, vertical mill, high pressure mill, powder mill and so on.Broken equipment and grinding equipment in the lot on the use of the waste cycle to make a great contribution, the use of construction waste and mine waste such as gangue variable of the mill crusher processing waste into treasure, recycle the waste cycle turning waste into treasure.Now appropriate to address the period of the global environment subject height, climate change and energy, environmental protection, low-carbon economy become issues of concern of the international companies.
This style of crusher uses compression to crush rockby squeezing it between two jaws: one stationary and one movable.The movable jaw (pitman) is attached to an eccentric shaft that causes it to move in a reciprocating motion.Rock enters the crushing chamber from the top and moves through the chamber, which gets narrower as it gets deeper, until it is caught between the two jaws, where it is squeezed until it fractures.
Working process: raw materials in big size go through hopper, and are sent to jaw crusher evenly by vibrating feeder for primary crushing.
