What if the crusher is used when the motor is hot?

When using the crusher, the motor will heat up. Ordinary customers will think this is normal and can be ignored, but often because it is ignored, it can cause other problems with the device, so the problem cannot be found. the reason.

First, when buying a crusher, the crusher model matches the motor. If the motor is small or large, it will easily fail, such as motor heating or even burning. Second, don't underestimate the crusher. Installation, good start-up is successful, the crusher installation should be installed and commissioned under the guidance of a professional; in addition, the blades of the crusher fan will fall off or wear and cause heat to the crusher motor. At this point we have to check whether the motor fan blades are off or worn, and should deal with the problem in time; in addition, the motor power of the crusher is too large, which will generate excessive wind speed. When the wind speed is too low, the discharge port is blown back, resulting in an output. Low, repeated return to the furnace and repeated damage to the material will cause the crusher motor to heat up. If the motor voltage is too low, the load on the motor will increase and abnormal heat generation will occur.

Open and closed loops: In the production of roll crushers, the cycle is divided into road loops and closed loops. The former is called a sieve and then broken, and the latter is called first broken and then sieved. First, the crushed material is sieved through the finished sieve, and then broken into the secondary crushing feed port to increase the yield of the finished product, and the needle-like content also increases. A broken sieve refers to a broken material. Enter the secondary crusher feed port and re-inject into the finished sieve for screening. The whole system is a closed system, no damaged materials are lost, the cycle load is large, but the shape of the product is good. In the actual production of the crusher, the choice of open circuit or closed circuit can be based on production demand;

Circulating load: The working process of the roller crusher is carried out in a closed loop. By increasing the vent and increasing the load in the cycle, the grain shape of the stone will get better. Throughout the process, the wear of each device in the system increases due to an increase in the cyclic load, but when the discharge port is adjusted, the load of the main crush motor can be reduced, and the finished pellet shape product becomes better. Therefore, in production, the adjustment of the cyclic load is very important.

Feed particle size: For roll crushers, the feed size can be processed by different types or different models. If the feed particle size is not suitable, the discharge quality does not meet the standard. For example, when the feed size is reduced from 100 mm to 50 mm, the needle content in the finished product is reduced by 38%, so the feed size should meet the requirements of the production equipment.
