Sep 22, 2021· Poor screening effect. ① Blockage of the sieve holes. If the raw coal has a high mud content and water content, the screen holes will be blocked. Vibrating screen troubleshooting: Clean the sieve holes, and then appropriately adjust the amount of spray water and the inclination of the vibrating screen deck. ② Severely worn sieve mesh.
DetailsJul 26, 2015· When the smaller rock has to be classified a vibrating screen will be used. The simplest Vibrating Screen Working Principle can be explained using the single deck screen and put it onto an inclined frame. The frame is mounted on springs. The vibration is generated from an unbalanced flywheel. A very erratic motion is developed when this …
DetailsThe coal delivered from the mine that reports to the coal preparation plant is called run-of-mine, or ROM, coal. This is the raw material for the CPP, and consists of coal, rocks, middlings, minerals and contamination. Contamination is usually introduced by the mining process and may include machine parts, used consumables and parts of ground ...
DetailsJul 26, 2015· The Type 70 Screen is usually made 4 ft. wide and from 5 to 10 ft. in length. For the rough work described above it can be relied upon to give a capacity of 4 to 5 tons per square foot when screening to about ½ in. and set at a slope of 25 to 30 degrees to the horizontal. The Type 50 Vibrator requires about 2 h.p. for its operation. Screen Capacity
