The raw coal is then fed into the pulverizer along with air heated to about 330°C (650°F) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.

INVESTIGATION OF THERMAL DAMAGE DURING THE GRINDING

During a grinding process there is possibility of both the grinder and the workpiece to be damaged. The damage can only be explained as a result of an attempt to dissociate structures by forcefully moving the atoms or molecules away from the main structure hence the release of binding energy in form of heat. If this dissociation occurs both in

How to Reduce Wafer Stress & Damage After the Backgrinding

Apr 20, 2020 Backgriding is a complex process, but some parameters can be taken to optimize this process and to reduce damage. After carefully grinding wafers to achieve ultra flat wafers, damages will still be present. The damage can penetrate two layers: the surface of the wafer which can be full of micro-cracks, causing warpage and stress in the wafer

fore, it is highly desirable that grinding wheels generate only very low damage to ground wafers. Since it is the post-polishing processes (such as polish-ing), not the grinding process, that produce the final surface roughness on silicon wafers, the surface roughness on ground wafers generally is not considered as a critical parameter.
