SMH series hydraulic cone crusher is a high-performance cone crusher. By optimized combination of the rotation rate, stroke and the crushing cavity, it realizes the laminated crushing and improves the yield greatly.
The mantle of the same diameter, the crushing stroke longer, larger crushing ratio, high output, low energy consumption;The effect of laminated crushing under full load makes particle-size distribution more steady, shape of product (cubic) more excellent.
SMH Series Cone Crushers adopt hydraulic locking and overload protection. When something which cannot be broken enters into the crushing chamber, hydraulic system will release the impact force smoothly to protect the crusher, and it can get back to the former discharging setting after the foreign material getting through, which can prevent block of the crusher.
When SMH series hydraulic cone crusher works, the motor drives the outer copper rotate through V-belt, host pulley, drive shaft, a small bevel gear, a large bevel gear. The outer copper forces crushing cone shaft axis of the outer copper to make rotating swing, making crushing surface sometimes near and sometimes leave the concave surface, so that the material is impacted, squeezed and bent in the ringlike crushing chamber consist of fixed cone and movable cone. After repeated squeezed, shocked, and bent, the material crushing to the required particle size is discharged from the lower part.
The particular crushing chamber adopting principle of intergranular lamination and matching rotor speed obviously improves the crushing ratio and productivity, largely increase the amount of cubic final product.
Adopting hydraulic protection and hydraulic cavity clearing, high degree of automation, the hydraulic system can be up top and discharge automatically when the crusher is blocked instantly or over-iron, which eliminates trouble of halting to clear the material manually. It makes the maintenance more easier, cost lower.

what is a hydraulic cone crusher? - hongxing machinery
When the cone crusher works, the rotation of the motor is performed by a pulley or coupling, the cone crusher transmission shaft and the crusher cone under the force of an eccentric sleeve to make a swing motion around a fixed point. Therefore, the crushing wall of the crushing cone is sometimes close to and sometimes away from the surface of the mortar wall fixed on the adjusting sleeve, so that the ore is continuously impacted, crushed and bent in the crushing cavity to achieve the ore crushing.
The motor drives the eccentric sleeve to rotate through the bevel gear to make the crushing cone rotate, which accomplishes the crushing work when the crushing cone is sometimes near and away from the fixed cone.
The connection between the support sleeve and the frame is compressed by a spring so that when an unbreakable object such as a metal block falls into the crusher, the spring will compress and deform to evacuate these objects and achieve insurance to prevent the machine from damaging.
If the foreign matter is stuck in the ore discharge, it can be solved by expanding the discharging port and then the cone crusher is automatically reset by the spring to resume normal work.
This hydraulic system controls the movement of 3 basic circuits. One is the action of the fixed cone hydraulic locking hydraulic cylinder, the second is the hydraulic motor that adjusts the gap between the moving and fixed cone. The third is the way of the hydraulic cylinder when the iron is released and cleaned.
The lock cylinder is installed between the lock ring and the adjustment ring. It can support the lock ring located on the upper part of the adjustment ring to ensure that the fixed cone is located in the broken position in the adjustment ring when the hydraulic cylinder is pressurized during the crushing process.
When the gap between the moving and fixed cones needs to be adjusted, the pressure of the locking hydraulic cylinder is released, and the motor on the adjusting ring starts to start. The gear on the motor engages the driving ring with the adjusting cap to realize the automatic adjustment.
The iron release cylinder is connected to the lower part of the mainframe and is fixed with the adopt to overcome the normal braking force. Abnormal operation or excessive crushing force generated by the foreign object as it passes through the crusher cause the adjustment ring to rise. Once the overload disappears or iron passes through the crusher, the crusher returns to normal. Besides, to clean the crusher, the adjustment ring needs to be removed from the mainframe.
This hydraulic system uses a fixed displacement plunger pump as the power source, that is to say, it converts the mechanical energy supplied by the prime mover into the pressure energy of the working medium (hydraulic oil). During this period, each hydraulic valve controls and regulates the pressure, flow, and direction, to ensure that the execution part (each hydraulic cylinder and motor) to complete the predetermined law of movement. The maximum pressure of the electromagnetic relief valve adjustment system in this circuit is 20MPa.
The locking circuit is controlled by accumulator pressure and zero leakage solenoid valve. Because the lock cylinder is always in a pressure-maintaining state during the working process, the use of an accumulator to maintain pressure can prevent the plunger pump from starting and stopping frequently. The locking cylinder is a plunger cylinder so that the zero-leakage solenoid valve is reset by the weight of the support part after the pressure is released.
Adjust the motor circuit by using a shuttle valve to control the motor running and stopping. Due to the working nature of the host, the motor needs to have a brake function. Therefore, the shuttle valve is used to control the brake of the motor. Thus, the motor can realize the function of oil-braking and oil-cut braking.
Accumulators are used to absorbing shocks in the iron release and cleaning circuits. Due to abnormal operation or excessive crushing force generated by the crusher when the main machine is working, the adjustment ring rises upward. When the adjustment ring rises, the hydraulic oil in the upper cavity of the hydraulic cylinder will be squeezed into the accumulator, then the nitrogen in the accumulator is compressed.
After that, the compressed nitrogen forces the hydraulic oil to return to the hydraulic cylinder, and the piston rod of the hydraulic cylinder is retracted, and the adjustment ring is returned to the original position. This circuit uses an accumulator to absorb shocks easily, easily and reliably.
The most common types of hydraulic cone crushers are single-cylinder cone crusher, multi-cylinder cone crusher, and fully hydraulic crusher.SCseries single-cylinder hydraulic cone crusher is developed with advanced crushing technology, integrating mechanical, hydraulic, electrical, intelligent control, etc.Thesingle-cylinder hydraulic cone crusherhas a new crusher structure, optimized laminated crushing cavity type, and a fully intelligent automation control system.

10 aspects distinguish sing-cylinder and multi-cylinder cone crusher
Cone crushers have three types, single-cylinder, multi-cylinder, and compound crusher machine. Compound series cone crusher is a comprehensive cone crusher with spring and hydraulic cylinder. The cone stone crusher equipment is easy to the identification. But the single-cylinder crusher and multi-cylinder crusher, which both are hydraulic cone crusher, many people have a bit difficult to distinguish them. This article analyzes the difference between single-cylinder and multi-cylinder cone crusher from 10 aspects. Such as structure, adjustment device, lubrication system, wear parts, crushing effect. . .
1) Upper frame parts: upper frame, rolled mortar wall, spacer, upper frame backplate.
2) Lower frame parts: lower frame, lower frame guard plate, lower frame inner lining plate, eccentric bushing, sealing barrel.

When the single-cylinder cone crusher operation normally, the spindle oil cylinder adds and dischargers oil is via oil pump. Then the spindle moves up or down to adjust the size of the discharge port. This adjustment way may cause the discharge outlet to be more difficult to lock when crushing the hard ore. A multi-cylinder cone crusher is through a hydraulic pusher or hydraulic motor to adjust. It drives the adjustment ring in the support sleeve rotation to achieve the adjustment. The advantage of this adjustment way is that the outlet is easy to lock.
Single cylinder over iron and cavity cleaning. As the iron over iron, hydraulic oil adds into the accumulator, and the spindle drops. After over iron, the accumulator will press the oil back, and the crusher will run normally. It also uses hydraulic pump when clean the cavity.
Overload protection of multi-cylinder. When the unbreakable foreign body passes through the crushing cavity or due to some reasons, the machine overloaded. The hydraulic safety system realizes the protection. The discharge gate increases, and the foreign matter discharges from the crushing cavity. If the foreign body gets stuck in the discharge port, the cavity cleaning system can be used which lets discharge ore mouth further increase. Then the foreign body discharge crushing chamber. Under the action of the hydraulic system, the ore discharge gate is automatically reset and the machine resumes normal operation.
The single-cylinder lubrication system adds oil by two oil inlet. One adds from the bottom of the main shaft into the ball bearing, frame bushing, rack bushing, main shaft bushing, and then lubrication of the small and large bevel gears. The other way is add from transmission shaft, lubrication the transmission shaft bush. At last, the two-way oil discharge from the same outlet.
A multi-cylinder lubrication system also has two ways. One is after entering the machine through the lower oil hole which divided into three branches after reach the central spindle.Another adds way from the hole on the transmission shaft rack to lubrication transmission bearings. Its oil return is through the small bevel gear lower oil return hole and dust cover oil return hole.
The single cylinder hydraulic cone crusher is similar to the spring cone crusher, the main shaft is combined with the dynamic cone. At the same time by the bowl bearing. Therefore, the spindle and the dynamic cone equivalent to the base support, eccentric sleeve drive spindle to provide crushing force. The spindle of multi-cylinder crusher is thick and short. The diameter can be designed to be large enough to stand directly on the rack (rather than inside the eccentric sleeve) . It is directly supported by the frame to provide higher bearing capacity, and the eccentric sleeve directly drives the cone to provide crushing force.
The single cylinder counterweight is heavy and thick. Because when the single cylinder cone crusher work, the spindle, and dynamic cone move to the tighten edge. The thick side of the eccentric sleeve is at the wide edge, at which point the center of gravity of the whole moving cone deviates to the tighten edge. Therefore, it is necessary to add a counterweight on one side of the eccentric sleeve to balance the whole dynamic cone. In addition, the counterweight is added to make the moving cone easier to move toward the wide mouth edge.
In general, single-cylinder and multi-cylinder hydraulic cone crusher can be full feed. The latter has no problem in achieving full feeding with high bearing capacity and can utilize the lamination principle. Aggregated rock crushing in the crusher cavity, and mutual extrusion at the same time. Crushing at the same time have shaping effect, so it is very good particle shape.
The multi-cylinder hydraulic cone crusher has high content of fine material, better fine crushing effect and good laminating crushing effect. But the single -cylinder intermediate crushing effect is better, and through the capacity large.
When crushing soft mineral and weathered ore, the single cylinder hydraulic cone has the advantage of large passing capacity. But in the crushing medium-hard and high-hard ore, the performance of multi-cylinder is more outstanding. For example, more than medium-hard ore fine crushing, in the same specifications cone crusher machine, the multi-cylinder can produce more qualified products. The harder the stone, the greater the difference.
The single-cylinder has a simple structure and reliable performance. The advantages of this crusher are one hydraulic cylinder, simple and compact structure, low failure rate and low production cost. The simpler the mechanical system structure, the lower the failure rate, the higher the reliability and the more stable the operation.
The top or side of the multi-cylinder can be disassembled and repaired quickly and conveniently. All crusher parts can be disassembled and maintained from the top or side, the moving cone and the top cone are easy to disassemble. It doesnt need to disassemble and assemble the frame, fastening bolts, and easy to replace daily.
The single-cylinder and multi-cylinder cone crushers are high-performance. The structure of the different so that each has its advantages and disadvantages. Compared with a single cylinder, multi-cylinder has more advantages of structural performance, maintenance, crushing efficiency, etc. Correspondingly, a multi-cylinder cone crusher price will be high, which may also be the user in the choice of the point that will focus on.
At present, there are some small multi cylinder hydraulic cone crushers manufacturers just make up from the charge of Simmons cone crusher. The spring changed into a hydraulic cylinder, but the internal structure is still the same.
Substantially, it still is Simmons crusher, users should pay attention when
