4 kinds Jaw crusher discharge gate adjustment mothods


1. spacer adjustment: use the lifting bolt to open the adjusting seat, between the rear thrust plate support and the rear wall of the frame, put or take away a group of spacers of equal thickness.By increasing or decreasing the number of spacer layers, the discharge port of the crusher decreases or increases.Spacer adjustment can be multi-level adjustment, the machine structure is relatively compact, can reduce the weight of equipment, but the adjustment must stop machine, large jaw crusher use this adjustment method.

2. hydraulic adjustment: rely on hydraulic cylinder to adjust the discharge port, the use of the rear thrust plate as a crusher safety device.The jaw crusher adopts hydraulic safety device, which is reliable, safe and easy to discharge faults.

3. support device adjustment: in the jaw crusher bearing part, generally cast with babbitt alloy sliding bearing, it can withstand a large impact load, and more wear resistance, but to low efficiency, the need for forced lubrication.

4.wedge block adjustment: it is the relative movement of two wedge blocks between the back thrust plate support and the back wall of the frame to achieve the adjustment of the crusher discharge port.Turn the nut on the bolt to make the adjusting wedge move up or down along the back wall of the frame and drive the front wedge to move forward or backward so as to push the thrust plate or the movable jaw to achieve the purpose of adjusting the ore outlet.Some domestic European jaw crushers use wedge adjustment, and the aforementioned is different, domestic European jaw crusher is usually used "horizontal wedge" (wedge is moving in the horizontal direction).Wedge adjustment can achieve stepless adjustment, convenient adjustment, saving time, no need to stop adjustment, but increased the size and weight of the machine.Small and medium jaw crushers often use this adjustment.

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
