working principle of single hydraulic cone crusher

working principle of single hydraulic cone crusher



At present, hydraulic cone crusher is widely used abroad.Using hydraulic technology, using hydraulic positioning mechanism, reliable work, and automatically remove iron pieces such as non-breakable material.The hydraulic system plays three roles: supporting the cone of the crusher, adjusting the discharge port and realizing overload protection.The hydraulic cone crusher can adjust the ore outlet and remove the non-broken material in about 1 minute, which shows that it is more advanced than the spring cone crusher.

Hydraulic cone crusher is divided into single cylinder and multi-cylinder type.

The lower end of the main shaft of the movable cone 3 is inserted into the eccentric shaft sleeve 4 and supported on the spherical disc above the piston of the oil cylinder;The piston is supported by high pressure oil below it.Because of the rotation of eccentric shaft sleeve, the moving cone makes conical movement.

The vertical shaft 1 and moving cone 2 of this crusher is all supported by the hydraulic pressure inside the hydraulic cylinder. The hydraulic pressure system consists of hydraulic cylinder 3, hydraulic box 4 and accumulator 5.The hydraulic accumulator is filled with nitrogen whose pressure is higher than the oil pressure required for crushing. When the ore discharge port needs to be increased, the oil in the lower hydraulic cylinder of the vertical shaft can be put back into the hydraulic tank. At this time, the dynamic cone drops and the ore discharge port increases.On the contrary, if you want to narrow the ore outlet, you can press the oil from the hydraulic box into the hydraulic cylinder, so that the moving cone rises.When the non-broken items fall into the crushing chamber, the hydraulic pressure of the oil circuit is greater than the nitrogen pressure of the accumulator. The piston of the accumulator compresses nitrogen and the oil enters the accumulator. The piston in the hydraulic cylinder drops and the moving cone drops accordingly.After the object is discharged, the oil pressure decreases, so the nitrogen pressure is higher than the oil pressure, the oil entering the accumulator is pressed back into the oil path to return to the hydraulic cylinder, and then the cone rises and returns to normal.In addition, the oil pressure in the oil circuit can be adjusted by using the valve, and the change of the oil pressure in the hydraulic cylinder can be mastered by using the hydraulic gauge.And according to the pressure gauge reading, according to the production requirements to adjust the size of the outlet.

Single cylinder hydraulic cone crusher is easy to realize automatic adjustment of crushing process.Its weight is lighter, the parallel belt of the crushing chamber is longer, and the particle size of the product is more uniform.However, the equipment installation and maintenance requirements are more stringent and accurate.

Operation of Jaw Crusher

图片
Operation Instructions of Jaw Crusher 1.The preparation before starting: (1) Inspect each bearing to ensure whether it lubricates well, and whether there is enough lubricating grease on the toggle plate joints and bearing inners. (2) Check carefully whether all fasteners are totally fastened. (3) Check whether the drive belt is under good condition, and change the belt if any damages can be found. When there is grease contamination on the belt or bell wheel, it can be clean up with a clean dishcloth. (4) Check whether the protective device is under good condition, if there are any unusual events and safety hazards conditions, should correct them and report. (5) Check whether there are any ore or other impurities inside the crushing cavity. 2.The starting of the crusher (1) After inspecting the machine and transmission parts are under good condition, the machine may starts. (2) This machine can only start under empty load conditions. (3) After having started the machine, shut down the

What factors affect the output of cone crusher

图片
What factors affect the output of cone crusher There are three main factors influencing the productivity of cone crusher : the number of times of the swing of the cone;The length of the parallel crushing area;The size of the engagement Angle.These three aspects directly determine the output of cone crusher. 1.the number of times of the swing of the cone The swing times of the crushed cone is one of the key factors affecting the crusher productivity. Because of the limitation of the meshing Angle of the crushing cavity and the parallel ore discharge area, the crushed ore is discharged along the taper inclined plane mainly by gravity and vibration.When the number of spindle rotation increases, the ore is easy to be discharged, but the number of rotation is too high, which is not conducive to ore discharge, sometimes resulting in faster speed and unable to produce.Therefore, the number of swing of the broken wall has a certain constraint on the improvement of productivity. 2.The l
