The daily maintenance of sand making machine is essential. The sand making machine must be allowed to stop at regular intervals and the internal wear of the machine must be observed regularly. Replace or repair. It should also be noted that the observation window should not be opened during the normal operation of the sand making machine, so as to avoid dangerous accidents.
The tension of V-belt of reversible sand making machine should be adjusted properly to ensure uniform loading of V-belt. When driven by two motors, the V-belts on both sides should be grouped and matched to make the length of each group as consistent as possible. Adjustments should be made so that the current difference between the two motors does not exceed 15A. In the working process, due to the high-speed equipment of sand making machine, special attention should be paid to the safety. Workers should stay away from equipment. If maintenance is required on the machine, the power must be turned off before operation.
Add proper amount of grease every 400 hours. After 2000 hours of operation, open the spindle assembly to clean the bearing. Normally, it can work for 7200 hours and replace the bearing with a new one. The upper bearing of the spindle assembly is a floating end and the lower bearing is a fixed end. After assembly, turn the pulley by hand to make it rotate flexibly. During the operation of the sand making machine, due to the high speed of the equipment, special attention should be paid to the safety production. Relevant personnel should stay away from the equipment. If maintenance is needed on the machine, it should be done after shutdown. It is recommended that you ask professional maintenance personnel to solve the problem. It is strictly forbidden to dismantle the core components without the permission of the manufacturer.
Regularly close and open the observation door to observe the internal wear of the sand making machine. The wear degree of the central feed pipe, conical cover, upper and lower runner bushing of impeller, circumferential protection plate and wear block should be replaced or repaired in time after wear. At the same time, replace the wear block to ensure that the weight of the wear block is the same. It is strictly forbidden to open the observation door to observe the internal working state during the operation of sand making machine, so as to avoid danger. The impeller body is found to be worn and replaced in time to find the manufacturer for repair. In particular, it is strictly forbidden to manufacture impellers without the permission of the manufacturer.
The main body of the sand making machine is made of high precision, high strength casting and special welding and materials. It has good rigidity, vibration resistance and long service life. The investment can be large or small, and the production method is flexible. Sand making machine can start from a small amount of investment in mold, or can be directly large-scale production. It can be produced in a fixed location or on the move. The sand making machine does not need very high production conditions. Simple industrial shed can be used as workshop, products are stored in open air, no warehouse is needed, and the quality of workers is not high.
The inlet size of sand making machine should be adjusted according to the required product size. When adjusting, loosen the t-row bolts and the tension spring. Use the jack up bolt to push in the adjusting seat, insert or remove the corresponding thickness of gasket, and then retract the jack up bolt. The adjusting seat is firmly fixed on the ear seat of the reversible sander under the weight of the movable jaw. Press the shim pack together.
Adjust the preload of the spring to ensure that the thrust plate and the thrust plate pad are in close contact when the sand making machine is working. However, as long as the preload is not issued, there should not be too much knocking at the door and then locking the adjusting seat. A layer of metal plate shall be laid on the basic mine drainage pipe, and the metal plate shall have sufficient inclination angle (determined by the fluidity of the material and shall not be less than 50 °) so as not to hinder the smooth discharge of the crushed product.
Since the sand making machine will vibrate violently when it works, it should be installed on the concrete foundation. In order to reduce vibration, noise and impact on the foundation of nearby buildings, please use it between hardwood pads, rubber bands or other damping materials.
