Due to depletion of very good good quality coking coal, washery feed coal now requires crushing to smaller sizes for liberation of coal particles from overall coal matrix. Suitable choice of expense productive and efficient dewatering technique is important for maximizing the recovery of fine coal with minimal feasible moisture content inside the dewatered goods as well as protection on the environment. We know, when the raw coals are mined from underground, they need to have to pass some coal operating process in order that coal is often utilised in our modern life. These coal fines are required to become beneficiated for keeping the overall top quality of clean coal. This final results in generation of massive quantity of fines with deterioration in good quality. Coal washer is an essential washing machine in coal washing method. Considering its importance, dewatering of fine coal was identified as a single in the thrust areas for research in coal beneficiation.

Only about 35days, after he made the order in our company, we sent our whole sand making line to Sudan by ship successfully. The whole line mainly consists of hopper, vibrating feeding, belt conveyor, jaw crusher, VSI5X sand making machine, vibrating screen, sand washing machine, and central controlling system and so on.until today the whole lien works with good performance, large capacity, even final particles etc. And we also send our excellent after-sales team went to Sudan to install the whole line for the customer and do freely training for them about how to operate correctly .Above is the information of one SBM customers’ who came from Sudan, and he bought one complete sand making line for granite sand processing two years ago.

Squat pillars are those with w/h ratios thatexceed 10.18p where lpwp hlph 7.”).54− 0.These pillars can carry very large loads, andmay even be strain-hardening (meaning thatthey may never actually shed load, but justmay become more deformable once they“fail.Intermediate pillars are those whose w/hratios fall between about 4 and 8.These pillars do not shed their entire loadwhen they fail, but neither can they acceptany more load. When these pillars areloaded to their maximum capacity, they failcompletely, shedding nearly their entire load.Strength of Rectangular Pillar•All strength formula were derived for square shaped pillar•So, what is the strength for a rectangular or rhombus shapepillar which is being developed in longwall or BordPillarmine?
