How does the sand making machine extend its service life?
The mechanism sand or the artificial sand making industry has gradually swelled and led the research and improvement of the heavy engineering equipment technology and process flow throughout the construction machinery industry. As a important part of the sand and gravel production line, the sand making machine plays an important role in the production of the entire mechanism sand, so the stability and use of its components is very important. The industry believes that the impeller equipment that plays a decisive role in material injection is an important component of the sand machine. The stability of its operation determines the working efficiency of the conveyor, feeder and sorting machine.
Following the steady improvement of China's economic situation, various construction projects have been launched, and the vigorous development of the construction industry has directly brought about the prosperity of the construction sand production industry, and the construction of sand supply malls presents a huge gap.
In the history of construction sand use, China's early construction sands mainly used natural sand such as river sand, river sand, sea sand and mountain sand, followed by economic construction to drive the rapid development of shopping malls. Natural sand collection is now sand-free. However, on the other hand, the phenomenon of building quality accidents due to the use of residual sand has also occurred from time to time. Therefore, we must maintain the following nine aspects when using the sand making machine:
- 1. The order of the sand making machine and the conveying equipment is: discharging, sand making machine, feeding; the crushing machine must be idling, and the material can be fed after the crusher works normally. The order of downtime is reversed.
- 2. Close the vortex chamber investigation door before driving to prevent the material from rushing out of the vortex chamber and risk.
- 3. Check the direction of rotation of the impeller. From the direction of the inlet, the impeller should rotate counterclockwise, otherwise the motor wiring should be adjusted.
- 4. Feeding should be continuous and uniform. The granules of the feed are strictly in accordance with the requirements of the rules, and the larger than the regular materials are prevented from entering the crusher, otherwise the imbalance of the impeller and the excessive wear of the impeller may be caused. The base is formed to block the impeller passage and the central feed pipe, so that the crusher cannot operate normally. Bulk should be removed in time when feeding.
- 5. If there is severe oscillation and abnormal noise during the operation of the crusher, stop it and check it.
- 6. When the discharging device stops, the feeding should be stopped in time. Otherwise, the crushing impeller will be formed and the motor will be burnt.
- 7. In addition to this, the use of high-performance impellers is also essential. In order to increase the service life of the sand making machine, Lida Machinery successfully utilized the high manganese steel structure, improved the eddy current rotation method, and the new impeller equipment with adjustable emission speed. The process efficiency can reach 1.2-1.5 times of that of the ordinary sand making machine. At the same time, the high wear-resisting structure and the optimized upper and lower lining plates are selected, which can effectively improve the service life of the sand making machine and save the capital and recovery cost for the user.
- 8. The smoothness of the machine is smooth and dry oil. The amount of addition is 1/2-2/3 of the bearing cavity. The crusher can increase the amount of smooth grease every time it is operated. After 2000 hours of operation, the spindle assembly was turned over to clean the bearing, and the operation was 7200 hours, and the new bearing was replaced.
