Typically, the jaw crusher according to the working principle of a long-term follow-up survey and customer records can be summarized: jaw crusher impact the efficiency of the main factors in the nip angle and the crusher jaw crusher rpm.

Nip angle is fixed jaw plate and fixed angle between the jaw, according to estimates of the angle of up to 32 degrees, and in the actual design is generally used in less than 25 degrees, the basic for 18 to 20 degrees because the rodents angle is too large, it will make the ore crushing chamber in which excessive force or even out of the collision up and even threatened the personal safety of staff or damage to other equipment; and with the nip angle increases, the reduction ratio to increase at the same time, productivity decline. Adjust the size of discharge port (port of discharge by adjusting the block size can be adjusted), the size of the nip angle change. In actual production, often based on the requirements of discharge to adjust the size of discharge port size. Therefore, to ensure that the requirements of particle size, as far as the port of discharge amplification is reasonable. However, note that the port of discharge in the regulation of size and productivity broken than to note the interaction between the

In a certain range, can be transferred by increasing the number of eccentric shafts to increase the production capacity of crusher, but the speed is increased at the same time the material will increase the crushing unit energy consumption. And if the speed is too large, would have been broken in the crushing chamber too late to exhaust the ore produced jams, but will reduce the production capacity of cement production equipment. Therefore, the jaw crusher has a number of revolutions is the best threshold.

Exhibition of Machinery to remind you: Jaw crusher wearing parts such as eccentric shaft, connecting rod, movable jaw plate and the liner and so should pay attention to lubrication and replacement. Strengthen the jaw crusher broken board lifetime from design selection, assembly, use the process improvement aspects such as well to strengthen the broken jaw broken board lifetime, jaw crusher to improve production efficiency, reduce production costs .

Cone crusher jaw plates is the use of two compression and bending on the role of materials, rough or broken pieces of various hardness of the material in the crushing machinery. The broken body from the fixed jaw plate and movable jaw plates, jaw plates close to the time when the two materials Jibei broken left jaw when the two less than the discharge opening of the material discharged from the bottom block. It's crushing action is carried out intermittently. This crusher due to simple structure, reliable and hard materials can be broken, etc. and is widely used in mineral processing, construction materials, silicate and ceramic industries.

Twenty of the 20th century to 80 years, 800 tons of material per hour, breaking the large cone crusher feed size has reached about 1800 mm. Commonly used cone crusher has elbow board and two single brackets. The former moving jaw at work only for simple circular swing, so called simple swing cone crusher; the latter also for the arc swing up and down movement, it is also called complex oscillating cone crusher.

Single mobile jaw crusher toggle plate upper and lower jaw movement to promote the role of nesting, and travel is greater than the upper level of the lower part of bulk materials easily broken, so the broken plate efficiency is higher than your elbows. The disadvantage is that jaw plate wear faster, and the materials have been crushed leaving the phenomenon of increased energy consumption. In order to protect important parts of the machine is not damaged due to overload, often the simple shape, size, smaller board design for the weak link in the elbow, making it the first overload of the machine deformation or fracture.

In addition, to meet the size requirements of different discharge and compensation jaw plate wear and tear, but also the addition of discharge opening adjustment device, usually in the seat and rear rack bracket placed in between the pads, or wedge adjustment. But to avoid damage due to replace the broken parts to affect production, but also can be used to achieve the insurance and the hydraulic adjustment device. Some cone crusher also has a direct hydraulic drive to drive movable jaw plate to complete the crushing of material action. These two types of hydraulic cone crusher transmission device, often referred to as hydraulic cone crusher.

Gyrating crusher cone crusher is the use of cone cavity within the shell of the cycle exercise, have squeezed the material, splitting and bending, crushing all kinds of hardness of ore or rock crushing machinery. Broken cone with the top of the spindle bearing bush in the middle of the beams, the lower end of the eccentric sleeve is placed in the hole. Shaft rotation, broken cone around the center line for the eccentric cycle exercise machine of its crushing action is carried out continuously, so the higher the efficiency of cone crusher. To the early 70s, large gyratory crusher has been able to handle the material per hour, 5,000 tons, the maximum diameter of feeding up to 2000 mm.

Gyratory Crusher two ways to achieve the adjustment of discharge opening and overload insurance: First, use mechanical means to adjust the top of the spindle nut, rotate adjusting nut, cone crusher can fall or rise, along with changes to the nesting population bigger or smaller, overloaded, by cutting off the pin on the drive pulley to achieve insurance; The second way is the use of hydraulic breakers hydraulic cycle, the spindle is located in the hydraulic cylinder of the plunger, the change under the plunger hydraulic oil can change the volume up and down position of crushing cone, thereby changing the size of discharge opening. Overloading, the spindle downward pressure, forcing the plunger into the hydraulic oil under the accumulator in the hydraulic system, so that subsequently broken down in order to increase cone discharge opening, the discharge of materials into the crushing chamber with a non-broken materials (iron, wood, etc.) in order to achieve insurance.

Cone crusher gyratory crusher working principle and the same, but only for operations in the crushed or finely broken machinery. , The crushing operation of the row of the general uniformity of particle size than crushing the high operational requirements, therefore, the lower part of the crushing chamber shall be a parallel to the area, the same time, the cycle must speed up the rate of broken cone, so the material in the parallel area more than once within the extrusion.

Comparison of the crushing crushing crushing job of large operations, so the volume had broken loose after a larger increase. To prevent the crushing chamber may give rise to obstruction, without increasing the discharge opening to ensure that the required size of the premise of discharge must be broken by increasing the diameter of the bottom cone to increase the total discharge section.

Cone crusher discharge opening smaller, mixed with a compound of the non-breaking material has resulted in accidents, and because, the crushing operation of the demanding schedule of particle size must be adjusted in the liner wear in time after the discharge opening, which tapered crusher insurance and adjusting device is more necessary than the crushing operation.

Cone crusher (cone crusher) work, the rotation of the motor through the pulley or coupling, transmission shaft and cone to force the Department of the eccentric sleeve for moving around a fixed rotation of a pendulum movement, so that the cone crusher broken wall sometimes close and sometimes put to leave the solid-mounted adjustment Babbitt rolling surface of the ore constantly under attack in the crushing cavity, squeezing and bending role in crushing ore achieved.

Foreign body can not break through the crushing chamber overload the machine or for some reason, the spring release system to achieve insurance, port of discharge increases, the foreign body from the crushing chamber discharged, such as foreign body stuck in the row of the ore can be used clean chamber system that allows mining to continue to discharge increased so that the foreign body eliminate crushing chamber. In the spring cone crusher under the effect of discharge port automatically reset the machine back to normal work. This series crusher cone crusher crushing points, the broken cone crusher and cone crusher crushing three, according to the different needs of customers to buy.
