Multi-cylinder hydraulic cone crusher is typical crushing equipment for medium crushing and fine crushing of hard materials. This types of cone crushers are developed on the basis of spring cone crusher. Its basic structure is similar to that of spring cone crusher. It is used in the industry of mining metallurgy construction chemical electric power transportation and others.
The product particle size depends on whether the crushing process is open-circuit or closed-circuit. If we want to obtain satisfactory product size we must know the required discharge port. Here the discharge port refers to an approximate value. Even if two crushers are in the same working condition the discharge port may not be the same.
Relatively small crushing chamber can set a smaller discharge port and better regulation of discharge port. It is easier to obtain good particle shape with the small crushing chamber. In terms of product size the best product size can be obtained by the short-headed crushing chamber. The second is the standard fine cavity the larger the cavity the less easy to obtain a good product granule. To ensure a good product particle size the crushing ratio should be limited to 3 to 3.5.
A good product particle shape should ensure that the ratio of maximum size to a minimum size of more than 90 of the product is less than 3the smaller the ratio the better. And the number of samples taken should be no less than 300. The product size of crushing materials is determined by many factors. But the main influencing factors are feeding crushing cavity discharging port crushing equipment and crushing technology.
Multi-cylinder hydraulic cone crusher must achieve full cavity feeding material is 300mm higher than the distributor. It can feed and level sensor chain and build a feeding bin to achieve full cavity feeding. Stable and continuous grading feeding can avoid the change of crushing power and the disconnection of grading. Meanwhile it can keep stable crushing cavity and discharging opening. The product grain size of wide grading feed is better than that of narrow grading feed.
Compared with Spring cone crusher JXSC HP cone crusher machine can get better particle shape and achieve the effect of vertical shaft shaping. A small crusher can also obtain a better particle size. The output and fineness of multi-cylinder hydraulic cone crushers are determined by power crushing force and discharge opening.
The way to increase the power is to increase the feed rather than reduce the discharge port. The best crushing power is about 80 of the rated power. The runout of the adjusting ring is the most obvious and intuitive expression of the super-crushing force of the HP cone crusher. The adjust ring runout and power peak will add additional stress to the crusher which will lead to the serious damage of the crusher.
The foreign materials in the crushing system are very harmful to the crusher machine. For example iron may cause the crusher to burn copper jacket frame cracking spindle fracture serious consequences. Closed-circuit cycle crushing used in the secondary crushing can provide precise small feed grade for fine crushing. It avoids too much fine material into the crushing chamber that the crushing chamber to achieve an ideal filling effect. It uses fine crushing can improve the grading of continuous feeding and improve the quality of products.
In general the rock softer the crystalline particles of the rock more coarse the product more coarse the shape of the crushing particles more better. For example we want to obtain 6 15 products. The secondary crushing adopts closed-circuit circulation which crushing to below 50 and the material screening below 6mm to ensure a stable 6 50 continuous grading for fine crushing. Fine crushing select multi-cylinder cone crusher short head cavity 13 15 discharge gate and closed-circuit crusher.
The abrasion of the material mainly affects the service life of the lining board. Increasing the manganese content of the lining board properly not more than 20 can increase the service life of the lining board. At present the most used lining board is ZGMn18Cr2 material. A good liner utilization rate can reach 50 or even 60.
Cone Crusher . Introduction Cone Crushers is widely used in mines cement plants and sandstone industries for medium crushing of various mine rocks such as iron ore copper ore non-ferrous metal ore granite sandstone etc. Working principle is as follows The cone body swings under the force of the eccentric shaft sleeve so that the concave is sometimes close to and sometimes away from the
May 28 2020nbsp018332The CRC320 combines the TG320 cone crusher and a 15 hp 42 wide discharge conveyor on a portable all electric chassis. The crusher is fitted with an overflow chute and removable overflow panel so the overflow can buffer feed surges in a closed circuit application. The trailer width and length allow easy movement from site to site.
Product overview. As a leading cone crusher manufacturer in China GATOR is committed to GCS cone crusher design manufacturing and sales. We provide standard cone crusher and short head cone crusher Cone crusher is suitable to crush the compression resistance less than 350Mpa ores and rocks. Standard Cone Crusher Cone Crusher has a large feeding size marker size is coarse so the
Product size is the main process index to measure the quality of sand and aggregate products. Here we share four factors affecting the product size of single cylinder hydraulic cone crusher.
The stroke is the distance from the loose side discharge port to the tight side discharge port of the cone crusher. The stroke has an effect on the particle size of the product. The stroke size depends on the eccentric angle of the cone crusher. The eccentric angle of single cylinder hydraulic cone crusher can be adjusted according to the actual demand.
The solution is that the eccentric angle is composed of an eccentric copper sleeve with multiple keyways and an eccentric sleeve and different eccentric angles are formed by rotating the eccentric copper sleeve corresponding to different keyways. In this way 18mm 25mm and 32mm strokes can be obtained. The particle size can be optimized according to the different properties of the ore and with appropriate stroke.
Uniform circular feeding can not only improve the product particle size and processing capacity but also make the crushing wall and mortar wall uniformly stressed and prolong the service life. In operation uniform circular feeding can be realized by distributing tray and the height between feeding hopper and distributing plate of the cone crusher should be adjusted properly.
When the height is too high only a small part of the stone passes through the distributor which cannot achieve uniform circular feeding. When the height is too low the stone is easy to block and reduce the processing capacity. In addition the single cylinder hydraulic cone crusher can not only give full play to the capacity of the crusher but also improve the product particle size.
3. The influence of crushing cavity type on product granularity
According to application the improved crushing chamber not only greatly improves the product particle size but also increases the cone crusher throughput.
The parallel zone is changed from 96mm to 145mm which increases the crushing times of stone in parallel zone from 1-2 times to 2-3 times. The particle size will be better when stones are crushed multiple times.
After the improvement the mesh angle of the crushing chamber is changed from 22 deg to 16 deg and the decrease of the engagement angle can clamp the larger stone prevent the stone from jumping upward during crushing so as to improve the filling rate of the stone in the crushing chamber of cone crusher form the laminated crushing reduce the needle and flake content of the product stone and optimize the particle size of the product.
Theoretically if the meshing angle is too large the ore will slide easily in the crushing chamber and the production capacity will be reduced at the same time the wear of lining plate and power consumption will be increased if the meshing angle is too small the crushing chamber will be too small and the ore capacity will be relatively reduced which will affect the cone crusher output and increase the manufacturing cost of the crushing equipment and the height of the machine.
