How Does The Crusher Achieve Normal Production Under High Temperatures?

Recently, the temperature has reached more than 30℃ in many places across the country. And the continuous high-temperature environment will bring many difficulties to the use of crushers and other mining equipment. In addition, rainy and humid summers will also affect the service life of mining equipment. So, are there any measures to reduce the impact of high temperature on the equipment and ensure the normal production of the equipment?

The impact of high-temperature environment on mining equipment:

1. In a high-temperature environment, the temperature of the crusher itself will increase, which is prone to unpredictable abnormalities, such as sudden shutdowns, sudden breakage of spindles, and other failures.

2. Because of the thermal expansion and contraction, high temperature will cause the parts of the crusher to expand, causing more friction and deviation at the occlusion of each component, which will not only affect the production schedule, and friction will further increase the temperature.

3.The high-temperature environment will increase the temperature of the lubricating oil of the crusher, reduce the oiliness and viscosity, and damage the local oil film, reduce the lubrication effect between the parts and the bearing capacity. Furthermore, the carbonized lubricating oil will cause tile burning.

4. High temperature has certain hazards to the engines, hydraulic systems, and circuits of crushing machinery in mining equipment. In the high-temperature environment, the hydraulic system will often experience failures such as pipe bursts, joint oil leakage, solenoid valve coil burnout, hydraulic valve jamming, and loud noise. Using the accumulator system, the accumulator may be damaged due to the high temperature of the hydraulic oil. Due to thermal expansion and contraction of the metal, the outer skin will be more likely to crack by aging circuits in the summer and result in short-circuit failure. The electrical components in the control cabinet are also prone to failures in high-temperature seasons, and key control components such as industrial computers and PLCs may also experience crashes, slow operation speeds, and control failures.

5. Working under high temperatures for a long time will cause the performance of the equipment lubrication system to deteriorate, the oil is easy to deteriorate, and the chassis and other transmission systems are easy to wear. At the same time, it will affect the appearance of the paint, the brake system, the clutch, the throttle control system, and the metal structure. Also manifested in: easy to produce air resistance, resulting in unable to supply oil. The high temperature will reduce the performance of the engine's air intake system, reduce the sealing performance, and increase fuel consumption due to engine oil leakage.

How does the crusher achieve normal production under high temperatures?

How to reduce the impact of a high-temperature environment on the crusher and keep the equipment in normal production in the hot summer? To achieve normal production under high temperature, the crusher can start from the following points:

1. Do a good job in the daily maintenance of crusher equipment. The operator should regularly check the equipment, replace the butter, adjust the belt, and check the core parts and wear parts. And the operator should always check the values on the various thermometers during work, and immediately stop the inspection and eliminate the faults immediately if any problems are found. For those who cannot find the reason for a while, we must not leave the crusher working without Troubleshoot.

2. Clean up the oil and dust on the motor body in time to ensure that the engine maintains good heat dissipation. Although some of the current equipment is equipped with a dust-proof system, which reduces the probability of shutdown due to dust, the dust problem will become more serious in summer due to the high temperature and dry air. For example, it is necessary to check the fixed bolt of the cone crusher dust seal slip ring regularly to prevent the dust seal and slip ring from falling off, causing a large amount of dust and ore to enter the body, causing the crusher to be scrapped or major economic losses.

3. Replace the appropriate oil viscosity grade for the equipment. Generally, the oil viscosity grade in summer is appropriately higher than other times. Motor oil and lubricating oil in various places need to be replaced with summer oil, the amount of oil is appropriate, check whether there is oil leakage frequently, and the fuel should be refilled in time.

4. Check whether the cooling system and fuel system are unblocked, and replace the aging wires, plugs, fuel pipes, screws, and tighten the fuel pipeline to prevent fuel leakage.

5. During the operation of the crusher, always pay attention to the temperature of the crusher's bearings. Under normal working conditions, the bearing temperature rise should be within 35 degrees and not exceed 70 degrees. Keep the bearing in a good lubrication state, and pay attention to whether the sound and vibration are abnormal.

6. Regardless of whether the equipment is stopped or working, try to place the equipment in a cool place, such as building temporary awnings and sun protection nets for the equipment, to avoid prolonged exposure to the sun, which will cause equipment aging and affect work quality and efficiency.
