What to do if the motor of the mobile crushing station heats up

When using a mobile crushing station, the motor generates heat. Ordinary customers will think this is normal and can be ignored, but often because it is ignored, it may cause other problems with the device, so the cause of the problem cannot be found. What should I do if the motor of the mobile crushing station generates heat? There are many reasons that cause the motor to heat up. First, it is necessary to rule out whether the motor itself has quality problems. Another thing is to insist on whether the crushing cavity is blocked or the feed rate is too fast to overload the equipment. There is also to check whether the lubricating oil of the crusher is sufficient and clean.

First of all, when purchasing a mobile crushing station, the crusher model must match the motor. If the motor is small or very large, it will easily malfunction, such as heating or even burning the motor. Second, don't underestimate the crusher. Installation and good start-up are a successful step. The installation of the mobile crushing station should be installed and debugged under the guidance of professionals; in addition, the blades of the mobile crushing station fan will fall off or wear and cause the heat of the crusher motor. At this time, we have to check whether the motor fan blades are off or worn, and the problem should be dealt with in time; In addition, the motor power of the crusher is too large, which will produce excessive wind speed. When the wind speed is too low, the outlet is blown back, resulting in output. Repeatedly returning to the furnace and repeatedly destroying the material will cause the crusher motor to heat up. If the motor voltage is too low, the load of the motor will increase, and abnormal heating will occur.

Open circuit and closed circuit circulation: In the production of mobile crushing station, the circulation is divided into road circulation and closed circuit circulation. The former is called a sieve and then crushed, and the latter is called a crushed and then sieved. First, the crushed material is passed through the finished product screen, and then enters the secondary crushing feed inlet for crushing, so that the output of the finished product is increased, and the needle content also increases. The first crushed screen refers to the first crushed material. Enter the feed port of the secondary crusher, and then re-enter the finished product sieve for screening. The whole system is a closed system, no damaged materials are lost, and the cycle load is large, but the product shape is good. In the actual production of the crusher, the choice of open circuit or closed circuit can be selected according to production requirements.

Ring load: The working process of the mobile crushing station is carried out in a closed loop. Increase the discharge port and increase the load in the circulation, the particle shape of the stone will become better. In the whole process, due to the increase of the cyclic load, the wear of each device in the system increases, but when the discharge port is adjusted, the load of the main crushing motor can be reduced, and the finished particle shape product becomes better. Therefore, in production, the adjustment of cyclic load is very important.

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