During the operation of the hydraulic cone crusher, due to frequent problems such as wear, tooth beating, and frequent maintenance, it has brought immeasurable cost burdens to the manufacturer and caused serious economic losses. In view of this, Bellian machine experts have summarized the frequently occurring problems of hydraulic cone crushers, analyzed the causes, and put forward some reasonable solutions.

1. Common faults of hydraulic cone crusher
1. Serious wear and tearing
Because the hydraulic cone crusher has been produced in a harsh environment for a long time, although the hydraulic cone crusher is less likely to be jammed, the wear and tearing of the teeth are very serious, and even the bevel teeth are undercut, resulting in the failure of the hydraulic cone crusher to operate normally. .
2. Frequent maintenance restricts iron slag screening production
Hydraulic cone crushers are often overhauled and overhauled for a long time. Generally, it needs to be overhauled once every half a month, and each overhaul takes nearly 24 hours, or even longer. When the undercutting of bevel teeth is serious, it is necessary to purchase bevel teeth, and the maintenance time will be longer. Due to the uncontrollable state and maintenance of the cone crusher equipment, this affects the planning and arrangement of the slag iron screening production, resulting in the failure to complete the economic indicators, resulting in passive production and sales.
2. Analysis of the cause of the failure
1. The protection device of the hydraulic cone crusher is not perfect enough;
2. The specifications of the slag and iron materials entering the machine exceed the specified design requirements, and the design requirements are ≤130mm;
3. The specifications of the slag and iron materials entering the machine meet the design requirements of the equipment, but the amount of slag entering is too large;
4. The slag iron material entering the machine exceeds the maximum size of the equipment and is stuck;
5. After the hydraulic cone crusher is blocked and shut down, it is forced to start with a heavy load;
6. The mismatch of the configured transmission motor not only affects the efficiency, but also seriously affects the normal production and operation of the equipment.
3. Solutions
At present, the domestic counterparts usually take measures to deal with the faults of hydraulic cone crushers: improving equipment materials, surfacing hard alloys, etc., and some manufacturers combine the above-mentioned multiple solutions for comprehensive treatment. According to the working principle of the hydraulic cone crusher, as well as the investigation and research on the cause of equipment failure in the early stage, Bellian machine experts suggest the following countermeasures for repair and transformation.
1. The slag material conveyed to the crusher is originally only the belt head wheel for iron removal, and then a permanent magnet hanging iron removal device is installed on the belt conveying the slag material into the crusher. After two iron removals, the slag iron can be effectively avoided. Enter the hydraulic cone crusher.
2. Adjust the current of the protection device of the hydraulic cone crusher so that it cannot be forced to start or instantaneously tripped under the condition of heavy load.
3. Conduct a comprehensive inspection of the metal content inside the hydraulic oil tank every month, and deal with any faults in time.
4. Improve the operation system, strengthen the supervision and assessment of the crusher's iron passing, and strengthen the joint responsibility assessment of the person in charge of the production line and the operator.
Practice has proved that if the processing plant adopts the above measures, the service life of the hydraulic cone crusher can be greatly improved, the operating cost can be reduced, and the working efficiency of the entire ore processing production line can be greatly improved. As a good manufacturer of hydraulic cone crushers, Bellian Machinery enjoys a very high reputation in China and is a leader in the field of crushers.
