In the use of crusher, the motor will heat up, the general customer will think that this is normal, can be ignored, but often because of its neglect, may lead to other problems of equipment, so the root cause of the problem can not be found. The following Jinan Mobile Stone Crusher Leasing Factory's small edition to analyze the following motor knowledge:
First of all, when purchasing crusher, crusher model must be matched with motor, if the motor is small or large, it will easily break down, such as motor heating or even burning phenomenon; second, do not underestimate the installation of crusher machinery, good start is the prerequisite for success, the installation of crusher should be professional. Installation and debugging under the guidance of the staff; in addition, the fan blade of the crusher will fall off or wear and tear, which will also lead to the heat of the crusher motor. At this time, we need to check whether the fan blade of the motor is falling off or worn, and find out that the problem should be dealt with in time; furthermore, the crusher motor has too much power, which will produce too large wind speed, under the high wind speed. It is too late to reach the outlet and is blown back, resulting in low output. Repeated crushing of materials will lead to heat of crusher motor. If the motor voltage is too low, it will also aggravate the load of the motor, resulting in abnormal calorific value.
Open-circuit and closed-circuit cycles: In the production of roller crusher, the cycles are divided into separate-circuit cycles and closed-circuit cycles. The former is called screening before crushing, and the latter is called screening after crushing. Screening before crushing refers to the crushing of the crushed material through the screening of the finished product before entering the second-stage crushing inlet for crushing, thus increasing the output of the finished material. Additionally, the needle flake content has also increased. First crushing and then screening means that all the crushed materials are put into the inlet and outlet of the second crusher, and then re-crushed into the finished product screening for screening. The whole system is a closed system with no loss of crushed materials and a large circulation load, but the product has a good grain shape. In the actual production of the crusher, it can be used. Selection of open or closed circuit cycles according to production requirements;
Cyclic Load: The crusher's working process is carried out in a closed-circuit cycle. By adjusting the discharge outlet and increasing the load in the cycle, the stone grain shape will be improved. During the whole process, the wear and tear of the equipment in the system will increase due to the increase of the circulating load, but when the discharge outlet is increased, the load of the main crusher motor can be reduced. The grain deformation of finished product is good, so it is very important to adjust the cyclic load in production.
Feed Size: For crushers, different types or models can be processed with different feed sizes. If the feed size is not appropriate, it will also cause the discharging quality not up to the standard. For example, when the feed size is reduced from 100 mm to 50 mm, the needle flake content in finished materials will decrease by 38%. The grain size of the feed should meet the requirements of the production equipment.
