Production of the plant 80~110 tons of aggregate with minus 10mm size per hour.The working principle is as following: firstly, the big block will be sent into jaw crusher to make a primary crushing, after that, the stone will be sent into vibrating screen to separate (the stone with suitable size will be separated out, the oversize stone will be sent into cone crusher to make a further process, and then returned back to vibrating screen to separate)

CONCLUSIONSCONCLUSIONSSensor Based Sorting is still a developing technology that is rapidly evolving. Improvements are continually being made in terms of sorter robustness and measurement sensitivity.• A very wide range of sensors are now available and in development and ispredominantly represented by EMOS Systems.• X-Ray transmission sorting has particular promise in the field of dry coal sorting. For other silicate minerals, the current top size that the X-rays can pass through is around 40mm.• The X-Ray fluorescence sorting technology, developed and operated in Russia, will soon be available for local testing.
