(l) The adjustment of the discharge is simple, simply by adjusting the oil level in the hydraulic cylinder located at the bottom of the spindle, that is, pressing the button on the control panel while observing the indicator of the adjustment amount.

(2) Prevent the spindle from falling When large pieces of ore enter the crushing chamber, the main shaft often jumps. To prevent the main shaft from falling, the piston in the balance cylinder can be lifted to support it. The balance cylinder is filled with air and oil

(3) Can restart with load, whencrusherWhen shutting down during operation, there is no need to remove the raw materials from the crushing chamber. Simply operate the hydraulic system to lower the crushing cone and discharge the raw materials from the crushing chamber, achieving immediate start-up.

(4) Reasonable structure

① Non blocking crushing chamber, the crushing chamber of this machine has been optimized in design, with the blocking point moved upward and smooth ore discharge, improving the ore passing capacity per unit time, reducing lining wear, extending service life, and saving energy.

② Reasonable eccentric bearings The eccentric bearing of the crusher is made of high lead bronze, which is suitable for low-speed heavy load and improves the service life of the eccentric sleeve. At the same time, replacing the inner lining can adjust the eccentricity of the crusher to meet production needs

③ The gear installation is reasonable, and the eccentric sleeve gear of the machine is installed below Provides good lubrication conditions for gears and extends their service life On the other hand, it can reduce the height of the frame, increase the stability of the crusher, and reduce the overall weight of the machine

④ Direct transmission, some crushers are indirectly transmitted, and the electric motor drives the eccentric sleeve through large and small pulleys. The machine is driven by an electric motor through a central shaft to directly drive the eccentric sleeve, reducing many supporting devices, occupying a small installation area, reducing infrastructure investment, and improving mechanical efficiency. The basic parameters are advanced and the spindle speed is high

② The crushing ratio is large, and some crushers generally have a crushing ratio of 7-8, while companies have a crushing ratio of 8-9. A large crushing ratio reduces

Product granularity provides ideal materials for the second stage of crushing, improving the overall efficiency of the crushing system

③ Variable eccentricity, this crusher can adjust the eccentricity (by replacing the copper sleeve) according to changes in the hardness of the ore and production capacity on site, to make it conform to actual production.

When non broken objects fall into the crushing chamber, the crushing force increases sharply, and the system oil pressure also increases accordingly. When the system oil pressure is higher than the accumulator oil pressure, does the hydraulic oil in the hydraulic cylinder pass through the one-way throttle valve? Enter the accumulator (at this time, the oil pressure of the hydraulic cylinder and the air pressure of the accumulator fluctuate between 1.1-1.5MPa, temporarily balanced). At the same time, the moving cone falls, the discharge port increases, and non broken materials are discharged. After the non broken material is discharged, due to the sharp decrease in crushing force, the oil pressure of the system also decreases. The pressure oil in the accumulator passes through the throttle valve? Slowly enter the hydraulic cylinder to automatically reset the moving cone.

When the geometric dimensions of non crushed materials are too large to pass through the discharge port, the oil pressure can rise to 1.5 MPa. At this time, due to the action of the electrical contact pressure gauge, the main motor can stop on its own. After parking, there are not only non broken objects stuck in the crushing chamber, but also a large amount of materials. To deal with this situation, the method of oil discharge and unloading (i.e. opening the shut-off valves 4a and 4b to lower the moving cone) and oil filling and loading can be used to repeatedly raise and lower the moving cone, thereby discharging the ore and non crushed materials blocked in the crushing chamber.
