First of all, when buying a crusher, the crusher model must be matched with the motor, if the motor is small or large, it will be easy to fail, such as the phenomenon of motor heating and even burning; Secondly, do not underestimate the installation of crushing machinery, a good start is the first step to success, the installation of the crusher should be installed under the guidance of professionals; In addition, the loss or wear of the crusher fan blade will also lead to the heat of the crusher motor, then we have to check whether the motor fan blade is off or wear, and the problem should be dealt with in time; In addition, the crusher motor power is too large, will produce too large wind speed, under the strong wind speed too late to the discharge port and is blown back, resulting in low output, re-furnace constantly repeated material crushing will lead to the crusher motor heat. If the motor voltage is too low, it will also increase the load of the motor leading to the occurrence of abnormal heat generation.
Open and closed loop: In the production of roll crusher, the cycle of separate cycle and closed cycle, the former is called the first sieve after crushing, the latter is called the first sieve after crushing, the first sieve after crushing refers to the material after the first crushing through the finished product sieve sieve and then into the secondary crushing feed port for crushing, so that the output of finished materials increases, the needle sheet content also increases, The first crushing and then screening refers to the first crushing material all into the secondary crusher feed port, after re-breaking and then into the finished product screen for screening, the whole system is a closed system, no crushing material loss, the cycle load is large, but the product particle shape is good, in the actual production of the crusher, can be based on the production needs of open or closed cycle choice;
Cycle load: The working process of the crusher is carried out in a closed cycle, adjust the discharge port, increase the load in the cycle, the stone particle shape will become better, in the whole process, due to the increase of the cycle load, the wear of the equipment in the system increases, but when the discharge port is adjusted, the load of the main crushing motor can be reduced, the finished product particle deformation is good, so in the production, It is very important to adjust the cycle load.
Feed size: For the crusher, different types or different models can process the size of the feed is different, if the feed particle size is not suitable, it will also cause the phenomenon of non-standard discharge quality, for example, when the feed particle size is reduced from 100mm to 50mm, the content of needles in the finished material is reduced by 38%, so the feed particle size should meet the requirements of production equipment.
