The sand making machine is the main equipment for producing machine-made sand, and the bearings, rotors, impact blocks and impellers are the key components of the sand making machine. In the process of use, it is very important to operate the sand making machine correctly, and it is also very important for the maintenance and maintenance of key components. Only reasonable use and maintenance of the sand making machine can ensure the production efficiency and service life of the sand making machine equipment.
The sand making machine must be started without load, because when the sand making machine is started, if there is material remaining in the crushing cavity, it may cause excessive starting pressure of the motor and burn the motor, and cause other damage to the equipment. Therefore, the sundries in the crushing cavity must be cleaned before starting, and the equipment should be started without load, and the material should be added after starting. The following editor will teach you how to maintain and maintain our sand making equipment.
1. Bearing
The shaft of the sand making equipment bears the full load of the machine, and regular lubrication directly affects the service life and operating speed of the equipment, so regular lubrication is required, and the lubricating oil injected must be clean, the seal must be good, and the lubricating oil must be used in strict accordance with the instructions standard.
Whether the bearing is not smooth will directly affect the service life and efficiency of the sand making machine. Therefore, we need to pay special attention when using it and check and maintain it regularly. When the sand making machine works for 400 hours, it should add a proper amount of grease. When it works for 2000 hours, the main shaft assembly should be opened to clean the bearing. If it works for 7200 hours, it must be replaced with a new bearing. up.
2. Rotor
The rotor is the part that drives the sand making machine to rotate at high speed. During production, the top, inside and lower edges of the rotor are all places that are prone to wear. Check whether the machine is running normally every day, and regularly check whether the transmission triangular belt is tight. If it is too loose or too tight, it should be adjusted appropriately to ensure that the triangular belt should be selected in groups so that the length of each group is as consistent as possible. If the rotor is unbalanced during operation, it will vibrate and wear the rotor and rotor bearings.
3. Impact block
The impact block is a part of the sand making machine that is seriously worn during work. The reason for the wear is also related to the unsuitable material selection of the impact block, unreasonable structural parameters or unsuitable material properties. The impact blocks corresponding to different types of sand making machines will also be different, so it is necessary to ensure that the sand making machine and the impact block are matched with the corresponding models. Wear is also related to the hardness of the material. If the hardness of the material exceeds the tolerance range of the sand making machine, the friction between the material and the impact block will increase, resulting in wear of the impact block. In addition, the gap between the impact block and the impact plate should also be adjusted.
4. Impeller
The impeller is one of the important parts of the sand making machine, and it is also a fragile part. Protecting the impeller and improving its stability can not only effectively improve the working efficiency of the sand making machine, but also prolong the service life of the sand making machine.
The rotation direction of the impeller device should be counterclockwise from the material inlet, otherwise the motor wiring position should be adjusted; the feeding should be uniform and continuous, and the size of the river pebbles should strictly follow the equipment regulations, and the river pebbles with too large particles will cause irregularities in the impeller. Balance and wear the impeller; stop feeding first when shutting down, otherwise it will cause the impeller to be crushed and cause damage to the impeller; it is also necessary to regularly check the wear of the impeller device, and replace the worn impeller in time to ensure the normal operation of production.
5. Periodically stop the machine and open the observation door to observe the internal wear of the impact sand making machine.
The wear degree of the central feeding pipe, cone cap, impeller upper and lower runner liners, circumferential guard plates, and wear-resistant blocks should be replaced in time after wear. When repairing and replacing the wear-resistant blocks, they should be replaced at the same time to ensure that the weight of the wear-resistant blocks is the same. It is strictly forbidden to open the observation door to observe the internal working conditions during the working process of the crusher to avoid danger. If the impeller body is found to be worn, replace it in time and find the manufacturer for repair.
Before starting the machine, please check whether the observation door of the vortex chamber is closed tightly, so as to avoid the danger of materials rushing out of the observation door of the vortex chamber.
