The coal mining scraper conveyor seems simple, but in actual production, it is one of the equipment with a frequency of failure. The correct maintenance and use of the coal mining scraper conveyor is particularly important. The following editor will introduce to you what are the problems of the coal mining scraper conveyor?
1. Increase throughput One of the problems encountered in the use of the coal mining scraper conveyor is the sub-full load operation. Its conveying capacity is determined by the cross-sectional area of the conveyed material and the chain speed. Generally speaking, if a conveyor has a throughput problem, it is nothing more than these two factors. To solve this problem, we must first accurately measure the conveying capacity of the conveyor. If the coal mining scraper conveyor fails to reach the rated capacity, the reasons can be found from the following aspects to find a solution to the problem.
2. Check the speed of the coal mining scraper conveyor Check whether the coal mining scraper conveyor is running at the drive shaft speed. During installation and maintenance, the chute on the drive unit may be installed incorrectly, or the belt on the drive unit may be loose and slip, causing the coal mining scraper conveyor to run at a speed lower than the rated speed.
3. Check the thickness of the material in the coal mining scraper conveyor There are several reasons for the unreasonable material thickness: one is that the inclination angle of the coal mining scraper conveyor installation is unreasonable, and the usually designed conveyor can only operate within a certain slope range. Another reason is that the coal mining scraper conveyor feed is not smooth or insufficient, such as mismatched feed equipment, abnormal feed gate, and obstacles at the feed port. Take corresponding measures for different reasons to increase the thickness of the material and the uniformity of the feeding.
4. Prevent material accumulation For coal mining scraper conveyor with intermediate discharge, material accumulation is another major problem in use. The coal mining scraper conveyor can be designed with multiple intermediate discharge points, but multiple intermediate discharge points greatly increase the possibility of material accumulation, which will eventually block the head of the coal mining scraper conveyor or cause cross-contamination. There are several measures to deal with the accumulation of materials.
