Replacement method for cone crusher parts

Cone crushers are one of the main mining machines widely used for ore crushing in various mining areas. The main components of cone crushers include the bowl liner, disc, gear, cone sleeve, eccentric shaft, crushing wall, bearing, etc. After a period of use during the crushing operation, the crusher will inevitably suffer wear and tear or component damage. This will directly affect the progress of the crushing operation, and at this time, these components need to be replaced. Replacement methods for cone crusher components: 1. The cone crusher bowl liner is fastened to the adjusting ring with U-shaped screws, and zinc alloy is injected between them to ensure a tight fit. When newly installing or replacing the bowl liner, the fastening should be checked after 6-8 hours of operation, and the U-shaped screws should be tightened again. 2. Due to friction, the disc wears, affecting the change in the gear gap. To ensure normal gear meshing, shims must be added to the bottom cover, and the thickness of the shims should be equal to the wear of the disc. 3. The cone sleeve and the hollow eccentric shaft must be tightly fitted, and zinc alloy is injected to prevent the cone sleeve from rotating. The zinc alloy must fill all gaps. Due to the hot injection of zinc alloy, the cone sleeve may be deformed. Therefore, the dimensions of the newly installed cone sleeve should be checked, and any inaccuracies should be corrected promptly. When manufacturing spare parts, they should be matched according to the actual size of the inner diameter of the eccentric sleeve to maintain the original fit. 4. The cone crusher wall is fixed to the cone body with a cone head, and zinc alloy is cast between them. After 6-8 hours of operation of the newly installed or replaced cone crusher wall, the fastening should be checked, and any loosening should be tightened immediately. 5. When the cone crusher is working, the ore must be distributed in the middle of the disc. To prevent the crusher from overloading and causing uneven wear of the liner, ore should not be directly loaded into the crushing chamber. The correct ore feeding condition is that the ore is evenly distributed in the crushing chamber by the distribution disc, and the ore fed should not exceed the horizontal level of the bowl liner. 6. When installing the bowl bearing, care should be taken to prevent the steel wire rope from damaging the oil seal ring (support it between the steel wire ropes with hardwood, etc.). During assembly, the supporting spherical surface should be scraped to ensure that the crushing cone and the bowl spherical surface are in contact with the outer circle, and the inner ring should ensure an annular gap of 0.35-0.5 mm. The bowl bushing is fixed to the bowl bearing housing with locking pins filled with babbitt alloy around it to prevent the bowl bushing from rotating along the circumference. The bowl bearing housing is fixed to the housing with a key (pin). If a gap is found between the bowl bearing housing and the housing during operation, it must be dealt with immediately.

Vertical ball mill

Vertical ball mills are suitable for grinding and dispersing coarse, hard, or pseudoplastic materials. Materials ground by vertical ball mills have uniform and fine particle sizes. Vertical ball mills can also mix several materials very uniformly. Working principle The grinding media are driven by the stirring shaft to perform forced mechanical shearing and grinding. The material is pumped from the bottom filter screen and pipeline of the grinding cylinder to the top of the grinding cylinder, allowing the material and media to fully contact and grind, completing one cycle until the required fineness is reached. Equipment advantages Vertical ball mills integrate material classification and grinding. The grinding media impact is intense, suitable for high-viscosity, difficult-to-grind materials such as high-abrasion carbon black. Compared with other ball mills, it has the following advantages: 1. Strong ventilation and drying capacity, using kiln tail waste gas to dry the moisture in the raw materials; 2. No dead corners in the grinding cylinder, good homogeneity, less equipment, simple operation; 3. Special stirring shaft structure, increasing the media collision rate, improving the grinding frequency; 4. Convenient production adjustment and control, strong adaptability to various performance raw materials; 5. Double-layer cylinder body, special cooling circulation path, good cooling performance, fast discharge, easy cleaning; 6. Less system leakage, reducing the specifications, investment, and power consumption of the electrostatic precipitator for treating waste gas. Use and maintenance 1. Place the equipment flat on the prepared foundation and fasten it with bolts. 2. Before starting, check whether all rotating parts are flexible, whether the motor electrical wiring terminals are firm and reliable, and whether the reducer is filled with lubricating oil. 3. Clean promptly after shutdown to prevent material drying, solidification, and affecting the next start-up. 4. After the machine is installed, do not start the machine before adding the grinding media. A ball mill is a key equipment for further crushing materials after they have been crushed. It is widely used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal ore dressing, and glass ceramics, for dry or wet grinding of various ores and other grindable materials. Test operation After the ball mill is installed and inspected and qualified, it can be subjected to a no-load test run. The test run of the ball mill should be carried out by a skilled ball mill operator and strictly follow the ball mill safety operating procedures. (1) The continuous running time of the no-load operation is not less than 12-24 hours. Any problems found during operation should be solved promptly. (2) After the no-load test run is normal, the load test run can be carried out. The load test run should be carried out in stages. During the load operation, the feeding should be adjusted according to the discharge situation to avoid unnecessary wear and tear of the steel balls and cylinder lining. 1. Add appropriate materials and 1/3 of the steel balls (refer to the ball mill general drawing for the maximum ball loading) and run for 12-24 hours. 2. Add up to 2/3 of the steel balls and run for 24-48 hours. 3. According to the discharge situation of the ball mill, the output of qualified products, and referring to the actual ball loading of similar ore dressing plant ball mills, determine the reasonable ball loading of this ball mill and conduct a test run for at least 72 hours. (3) The increase in the above load and the duration of the test run should be determined based on the running-in situation of the large and small gears and reducer gears (temperature rise, noise, tooth surface contact, etc.). Before the tooth surface contact accuracy reaches the design requirements, full-load operation is not allowed. (4) During the test run, the cooling and lubrication systems should work normally. The main bearing, transmission bearing, and reducer temperatures should be normal. (5) After running for 24-48 hours with 2/3 of the steel balls, all bolts should be checked and tightened again. (6) The test run work should carefully record all items.
