2021-4-29 · 5. Water in the oil of the crusher will cause the oil level of the oil tank to rise. The water pressure in the cooler is higher than the oil pressure, the water leakage of the cooler, the water supply of the water seal is too large, or the water supply pipe is blocked can cause water to be mixed in the cone crushing oil, and the oil level in the oil tank is "forced to rise".
2019-9-2 · CONE CRUSHER. Cone crushers are similar to gyratory crushers in that they have a mantle that rotates within a bowl, but the chamber is not as steep. They are compression crushers that generally provide reduction ratios of 6-to-1 to 4-to-1. Cone crushers are used in …
2013-4-4 · During the operation of certain cone crushers, an alarm may sound if any of the following abnormal conditions occur for more than five seconds: a low feed-line oil flow; a low feed-line oil pressure; or a high return-line oil temperature. If these conditions continue to occur, a time-delayed shutdown of the crusher may occur.
2019-8-1 · Jaw crusher is usually used for primary crushing, and cone crusher is used for secondary crushing. The material of crusher plays an important role in its working efficiency and service life. However, the regular operation and maintenance are important, too.
2019-9-5 · High Pressure Grinding Rolls offer an energy-efficient way to crush pebbles and alleviate bottlenecks caused by conventional mills. Weir’s response to COVID-19: Safety is our number one priority and we have rigorous measures in place to protect our people, partners and communities while continuing to support our customers at this time.
2020-12-1 · Crusher Management System (CMS), a pressure monitor system is supplied. This system displays the hydraulic pressure on a meter that is usually located in the operator’s cabin and can be linked to a plant control PLC. The same system protects the crusher if the hydraulic pressure exceeds the recommended pre-set crushing pressure.
2019-2-25 · Excessive reduction ratios reduce production rates and shorten crusher life. If you exceed what an HSI or cone crusher is designed to do within its configuration, you can expect to decrease the lifespan of certain components, because you are putting stresses on parts of the machine that weren’t designed to bear that stress.
2020-9-2 · In the cone crusher working process, the feeding should be even. If the feeding is uneven, the production capacity will be reduced, the product size is too large, the spring action is frequent, the pressure of the bowl bearing is high, and the power consumption will rise. Too much pressure can also lead to "uncontrollable speed" and shaft
Rotating speed of moving cone The rotation speed of moving cone is an important factor affecting the output of crusher. If the rotation speed is too slow, the material will slide through the crushing chamber along the contour of the moving cone liner plate, and the time it takes to pass through the crushing chamber is long, so the output is certainly low, and the particle size of the product
2013-3-6 · To check if the water pressure is too low and to increase the pressure as much as possible; 3. To clean the cooling system and then to check the temperature of the cooling water. Fault five: there is water mixed in the oil and the oil increases in the oil tank.
