Hydraulic Cone Crusher

GEP's hydraulic cone crusher adopts laminated crushing method, which has high crushing efficiency. Because laminated crushing not only has the interaction between the material and the tooth plate, but also the interaction between the material and each other, through the mutual friction and extrusion between the high-density materials, high crushing efficiency can be obtained, and at the same time the crushing between the materials makes the materials impact the liner plate less wear, thus the liner plate wear rate is reduced. In addition, the laminate crushing makes the material needle-like content significantly reduced, and the quality of the finished material is improved.

The traditional cone crusher uses extrusion crushing, which has low crushing efficiency; the material directly impacts on the liner, resulting in fast liner wear and increased replacement costs; the high needle flake content in the finished product is not conducive to the recycling of stone materials.

1）Adjust the size of the discharge opening: by adjusting the up and down position of the shaft, thus adjusting the spacing between the dynamic cone and the outer cone liner. When the spacing becomes smaller, the discharge size will be smaller; when the spacing becomes larger, the discharge size will be larger. 2）Compensation of liner wear: after the liner wears, the distance between the inner and outer cone becomes bigger, the shaft and inner cone can be raised appropriately to reduce the distance between the inner and outer cone, this operation can be completed by the automatic compensation function of the control system. 3）Over iron and over load protection: The hydraulic cylinder is connected to the accumulator, when the crusher over iron or load suddenly increases, the hydraulic oil of the hydraulic cylinder can flow back to the accumulator instantly and quickly lift the piston rod, thus protecting the equipment parts and reducing the damage of the impact load on the equipment.

The key to the maintenance of the hydraulic system of the hydraulic cone crusher is to keep the hydraulic cylinder and the hydraulic oil clean. Must be strictly in accordance with the requirements of the hydraulic system to choose the appropriate hydraulic oil, and cannot be mixed with other brands of hydraulic oil to add. When adding hydraulic oil to the hydraulic system, it must be filtered strictly with a clean oil filter before adding to the hydraulic cylinder, and the amount of oil added should be filled with clean system piping and machine components, and kept within the range specified in the oil label. During operation, the quality of the hydraulic oil should be checked regularly to prevent water, dust or foreign objects from entering and to keep the hydraulic oil clean at all times.

On no-load test run: 1）Start or stop in strict accordance with procedures. 2）The hydraulic adjustment device is locked according to its operating procedure and the feed opening is adjusted to the size required for use. 3）Forward or reverse rotation of the moving cone should not exceed 15 revolutions per minute. 4）Bevel gears should not have shocks and periodic noise. 5）The lubrication system works normally, the oil pressure should be 0.05-0.15MPa and the return oil temperature should not exceed 50℃. 6）Normal continuous running time of not less than 2 hours

On load test run: 1）Load check of items checked in no-load test run. 2）In normal crushing, there should be no sharp vibrations and abnormal loud noises. 3）Test run time should be 48 hours of normal continuous operation (short stopping time allowed for inspection). 4）No runout in the bearing sleeve without over-ironing; smooth discharge in case of over-ironing. 5）The feeding volume is gradually increased from a small amount to full load, and the material should be evenly distributed in the crushing chamber

1）Lift out the eccentric sleeve and grind the worn parts of the straight and tapered sleeves to ensure the fineness of the friction surface. 2）Check the fixing of the straight sleeve and fix it with the fastening screw. 3）When installing the bowl-shaped bearing frame, it should fit closely with the frame and should not appear to be swinging. 4）Strictly control the rotational speed of the moving cone, too low or too high speed of the moving cone will affect the production efficiency. 5）Scrape the spherical surface of the replaced bowl tile support to ensure that the spherical surface of the crushing cone and the inner circle of the bowl tile do not come into contact with each other.

1）Strengthen inspection , operate in strict accordance with safety operating procedures, and repair any abnormalities found in a timely manner. 2）Strict control of particle size and absolute prohibition of collision between mantle and concave. 3）Prevent unbreakable materials from entering the crushing chamber to avoid accidents caused by a sharp increase in shaft load. 4）Observe the wear of the liner plate regularly to prevent it from falling off due to over-wear and getting stuck in the crushing chamber to damage the equipment.
