1. Tripping phenomenon

Cone crusher is a commonly used mining crushing equipment, widely used in mining, metallurgy, chemical industry and other industries. However, tripping may occur during use, affecting the normal operation of the equipment. Tripping refers to a protective measure in which the power supply stops supplying power to the circuit due to excessive current and the protective device is activated. Specifically, the machine stops suddenly, the control cabinet cannot be powered on, and the solenoid valve cannot work normally. The following is the possible causes and solutions of electrical failures analyzed by Xin Gaonai Heavy Industry:

2. Tripping causes

(1. Unstable voltage: When the power supply voltage is too high or too low, and the power supply phase sequence is disordered, the starting current of the cone crusher motor is large, which is easy to cause tripping.

(2. Equipment overload: When the material processed by the cone crusher is too large, the motor current is large, which is easy to cause tripping.

(3. Equipment aging: In the cone crusher that has been used for a long time, the equipment may have problems such as wear and aging, which will reduce the performance of the equipment and cause tripping.

(4. Filter blockage ：The oil pressure in the front and rear oil pipes is different

(5. The oil temperature is too high or too low: there is no oil flow in the oil flow indicator, and the oil temperature exceeds 45℃

(6. The safety valve fails and the oil pressure is too high

(7. Uneven or excessive ore feeding and impurities such as metals will cause tripping

(8. The cone machine transmission system is loose, which will cause unsmooth transmission and cause tripping

(9. The cone machine transmission gear is worn and the screws are loose

3. Solution

(1. Stabilize the power supply voltage: select cables and plugs with stable voltage, and install voltage stabilizers and other equipment to eliminate factors such as unstable grid voltage.

(2. Reduce equipment load: For cone crushers, you can reduce equipment load and avoid tripping by controlling the feed speed and mastering the appropriate crusher speed.

(3. Check and repair equipment: Regularly check the internal equipment of the cone crusher. If abnormal conditions such as abnormal noise or equipment heating are found, timely repair and treatment are required to avoid the instantaneous aggravation of the fault and causing tripping.

(4. Clean the filter. First, make the oil not pass through the filter, then remove the filter for cleaning. In this way, the oil is directly supplied to the crusher for no more than 2-3 hours.

(5. If the oil temperature is too low, heat the oil. If it is too high, add cooling water and clean the cooling Device

(6. Replace or adjust the safety valve

(7. Evenly feed the material, not too much or too large to avoid overload operation

(8. Check whether the transmission chain and belt are installed correctly, and adjust the position of the loose or worn parts

(9. Replace the worn gears and tighten the screws

In summary, the reasons for the cone crusher tripping may be various. It is recommended to check the equipment before using it (regular maintenance and maintenance) to ensure that all parts of the equipment are operating normally. If there is a tripping phenomenon, it needs to be checked one by one and the right medicine is prescribed. Eliminating faults can not only improve the working efficiency of the cone crusher, but also extend the service life of the cone crusher.
