Product principle
The upper end of the main axis equipped with a broken cone is in the band in the middle of the beam, and its lower end is placed in the eccentric hole of the shaft cover. When the axis sleeve rotates, the crushing of the center line of the crushing cone is performed by the eccentric rotation movement. By the early 1970s, a large -scale rotary crusher had 5,000 tons of materials per hour, and the maximum diameter of the materials could reach 2000 mm. The rotary crusher uses two ways to realize the adjustment and overload insurance of the discharge port: First, the mechanical method is used. The upper end of the main axis has adjusted nuts, rotating and adjusting the nut. When it becomes larger or smaller, when overload, the insurance sales on the transmission belt wheel to achieve insurance; the second is the hydraulic rotation crusher using a hydraulic method. The volume of the hydraulic oil can change the upper and lower positions of the broken cone, thereby changing the size of the rowed mouth. During the overload, the pressure under the spindle increased down, forcing the hydraulic oil under the plunger to enter the storage device in the hydraulic transmission system, which reduced the broken cone to increase the discharge port. Broken objects (iron, wooden blocks, etc.) to achieve insurance.
product advantages
The rotary crusher and the bacterial cone crusher are a type of cone crusher. The rotary crusher is a coarse crusher. Compared with the jaw crusher, its advantage is that the crushing process is continuously carried out along the circular crushing cavity, so the productivity is high and the power consumption is low. The work is stable. Suitable for crushing materials. It can be seen from the particle size distribution curve of the finished product. In the composition of the granularity of the finished product, the granularity of the material that exceeds the width of the outlet mouth is smaller than the jaw type crusher, the number is also small, and the particle size is relatively uniform. In addition, the original material can be directly poured into the inlet from the transportation tool without setting a feeder. The disadvantage of the rotary crusher is: complicated structure. The price is higher; the maintenance is difficult, the repair cost is high; the fuselage is high, so that the cost of the factory, the foundation and other structures increases.
Rotary crusher is suitable for factories and ingredients with large production volume. According to experience, if a rotary crushing function meets the production requirements when selecting the type, two jaw types must be required in the jaw type, and one rotary crusher should be considered.
Work characteristics
(1) Simple and reasonable structure and low operating costs. Use the principle of stone and stone to wear less.
(2) High crushing rate and energy saving.
(3) It has fine and rough grinding functions.
(4) The content of moisture in the material is small and the moisture can reach about 8%.
(5) The more noise is less than 75 decibels (DB level), and less dust pollution.
(6) Suitable for crushing, hard and hard materials.
(7) The product is established, with large accumulation density and extremely small iron pollution.
(8) The impeller is small and easy to repair.
Failure and exclusion method
1. Failure phenomenon: fine particle size;
Reason: Many hammer heads;
Solution: Reduce one or two layers of hammer heads.
2. Failure phenomenon: thick particle size;
Reason: belt loose or low speed;
installation method
1. The equipment should be installed at the level of the concrete base and is fixed with the anchor rod.
2. Install the main body and vertical level that should be noted.
3. Check whether some bolts are loose after installation, and strengthen whether the host Guobang Gate and the requirements are tightened.
4. Configure the power cord and power control switch according to the equipment.
5. After the inspection is completed, the short load test, test, production can be normal.
Operating program
1. Before starting, check whether the agency should be watched, and the door is strictly prohibited during the operation of the machine to prevent danger.
2. The crusher must be launched in an empty start, which will only be produced after normal operation.
3. According to the requirements of the size of the material particles, the conference has caused equipment damage and low output.
4. In the result of abnormal interrupt results, stop inspections, solve problems, and then used for production.
5. Add the lubricant regularly to rotate the bearings parts.
