The sand making machine is an important equipment in the sand making process. It consists of a hopper, a distributor, a crushing cavity, an impeller body, a main shaft assembly, a base, a transmission device, and a motor. This article shares with you 7 reasons and countermeasures for the sudden shutdown of the sand making machine.
1. The material in the crushing cavity is blocked
The blockage of materials will cause the equipment to stop suddenly. The reasons for the blockage of materials in the crushing chamber of the sand making machine are as follows:
(1) Feeding is too fast. When the sand making machine is just started, if the material put in is too large or too hard, it will cause the equipment to be blocked, and there will be vibrations, so the equipment cannot be officially put into production when it is started. At the same time, it is not easy to put materials too fast, otherwise it will cause blockage.
(2) The size of the discharge opening. When the discharge port of the sand making machine is too small and exceeds the minimum range of the equipment, some larger materials will accumulate at the discharge port of the crushing cavity, resulting in unsmooth discharge, and in severe cases, a crushing cavity will appear. The phenomenon of clogging.
(3) Due to the high water content or high viscosity of the crushed material, it will stick to the outlet of the crushing cavity when the sand making machine is crushed, which will affect the discharge of the material and cause the phenomenon of blockage. It is recommended that when crushing materials, screening should be carried out first to avoid blockage during work.
(4) When the sand making machine is crushing, when the hammer is worn or uneven, the crushing force of the hammer will be reduced. When crushing hard materials, the crushing operation cannot be completed, resulting in uneven or excessive crushing of the materials Phenomenon, and reduce the service life of the hammer. At the same time, the material is too large to affect the discharge of the discharge port, and in severe cases it will cause the crushing cavity to be blocked.
Responses
If the material in the crushing cavity is blocked, the material needs to be cleaned up. In subsequent use, materials with large particle size or high water content are prohibited from entering the machine, and the feeding should be kept uniform to avoid excessive feeding.
2. The triangle belt is too loose
Check whether the V-belt is too loose or loses tightness.
Responses
If it is too loose and cause the machine to stop, you need to adjust the tightness of the V-belt. If the V-belt loses its tightness due to prolonged use, the V-belt needs to be replaced.
3. The working voltage is not suitable
When the working voltage of the production site is too low, it is not enough to maintain the normal operation of the sand making machine and shut down.
Responses
Need to select a voltage that meets the requirements of the device.
4. The internal parts fall off
If there is a sound of metal collision before the equipment is shut down, it may be that a part in the crushing cavity has fallen and the sand making machine suddenly shuts down.
Responses
It is necessary to check the inside of the equipment to confirm that the internal parts have fallen off, and then install it correctly.
5. The impeller is stuck
When metal and other hard objects enter the crusher, the impeller of the sand making machine may be stuck, causing the equipment to fail to work.
Responses
It is necessary to strictly control the hardness of the material, and prohibit the entry of unbreakable materials.
6. The spindle is broken or the bearing is locked
Responses
If the main shaft is broken, the worn main shaft needs to be repaired or replaced.
If it is caused by bearing lock, it is necessary to find out the cause of lock lock, install the bearing correctly, ensure that the bearing has a certain working clearance, and do a good job of lubricating the bearing, otherwise the problem cannot be solved fundamentally.
7. There is a problem with the device connection line
If the connection line is broken or the contact is poor, the sand making machine will suddenly stop, especially when there is no sound without warning, it is likely that there is a problem with the connection line.
Responses
If the equipment connection line is broken or has poor contact, it needs to be adjusted or replaced in time.
