With the vigorous development of the construction industry, the increasing amount of sand for engineering use and the decrease in natural sand resources have made it difficult to meet market demand. The promotion and application of artificial sand is an inevitable choice for the development of gravel industry in China. The application of artificial sand also stimulated the entire construction machinery industry to research and improve the technology and process flow of heavy mineral processing equipment. As the sand making machine that occupies an important position in the sand production line, the stability and durability of the components are particularly important. The stability of the work determines the related conveyors, feeders, sorting machines, etc. Work efficiency. In order to prolong the service life of the sand making machine, SBM mining machine is recommended to optimize the working process of the sand making machine, mainly in the following aspects:
1. Check whether the door of the vortex chamber is closed before driving to prevent the material from rushing out of the vortex chamber.
2. Check the rotation direction of the impeller and look from the direction of the inlet. The impeller should be rotated counterclockwise, otherwise the motor wiring should be adjusted.
3, the starting order of the sand making machine and the conveying equipment is: discharging → sand making machine → feeding; crusher is started with no load and can be fed after the crusher runs normally. The shutdown sequence is the reverse of the boot sequence.
4. Feeding granules strictly according to the stipulated requirements, it is forbidden to enter the crusher beyond the stipulated materials, otherwise, it will cause the imbalance of the impeller and excessive wear of the impeller, causing the plugging of the impeller passage and the center feeding pipe to make the crusher unable to work normally. Bulk material was found to be eliminated in time.
5. When the discharge equipment stops, feed should be stopped in time. Otherwise, the impeller will be crushed and the motor burned.
6. Feeding continuously and evenly.
7. During the operation of the crusher, there shall be no severe vibration and abnormal noise; otherwise, it shall be stopped and checked.
8, the lubrication of the machine is dry oil lubrication method, the amount of 1/2-2/3 of the bearing cavity, the crusher add a proper amount of grease for each shift.
9. In order to ensure the energy saving of the sand making machine, the tension of the driving triangle tape of the sand making machine should be adjusted properly to ensure the uniform force of the triangular tape. When the dual motors are driven, the two sides of the triangle tape should be grouped and matched. The group length is as consistent as possible. Stop the observation door at regular intervals to observe the internal wear condition of the sand making machine. The degree of wear of the center feed pipe, conical cap, impeller, down flow channel lining plate, circumferential guard plate and wear-resistant block should be promptly replaced or repaired after wear and replace. When grinding blocks should be replaced at the same time, to ensure the same weight of wear blocks. It is forbidden to open the observation door during the work of the crusher to observe the internal working conditions so as to avoid danger. It was found that the impeller body was worn out and promptly replaced by the manufacturer. The Sand making machine adds proper amount of grease every 400 hours of work, and works for 2000 hours to open the main shaft assembly to clean the bearing. Generally, it will work for 7200 hours and replace the new bearing. The upper bearing of the main shaft assembly is a floating end, and the lower end bearing is a fixed end. After the assembly, pulling the pulley by hand should be flexible.
In addition, the use of high-performance impeller is also. In order to increase the service life of the sand making machine, the SBM mining machine utilizes a high-manganese steel structure to improve the novel impeller device in which the vortex rotation mode and the emission speed can be adjusted adaptively. Effectively improve the service life of the sand making machine, saving users money and recycling costs. SBM ore sand machine has small particle size, uniform particle size, large production capacity, long hammer life, small supporting power, variable three-stage crushing, secondary crushing, simplified process, simple structure, easy maintenance, and stable operation. SBM Mineral Machinery provides you with detailed technical solutions and after-sales services.
