Coal dry preparation,ROM-JIG and XRT X-ray transmission

Coal processing mainly has two aspects water washing and dry processing. For water washing there’s process like jigging, DMC(dense medium cyclone) and flotation, the advantages are: mature process technology, big capacity; disadvantages are: heavy construction investment, high operation cost, and relatively heavy water consumption and waste.

Dry Ice Blasting Advantages Iceberg Dry Ice

Cold dry ice is -78.5 celcius, and sticky substances like glue, tar, ink etc. are cleaned very effectively because the contaminant is frozen and then chips off! Thermal Shock dry ice will cause the surface and contaminant to change temperature at different rates causing a micro-thermal shock. This helps to pull them apart so cleaning is more effective.
