Specimen Grinding Machine. Used to grind and polish concrete specimens, natural stones, ceramic materials, rock samples etc.The cube cylinder and core specemens can be easily locked on the table and the grinding head can be radially moved either manually or automatically in both directions so the only manual operation requested is the lowering of the grinding head by the top hand wheel.
Drilling mechanics and performance The drill rate that can be achieved with a specific bit is de-termined by the aggressiveness of its design, the weight on bit (WOB) applied, the rotations per minute (RPM) and the rock strength. When the RPM or WOB are increased, the rate of penetration (ROP) should increase proportionate-ly. If the increase ...

Samples of Hwangdeung granite from Korea and Berea sandstone from USA, both containing sliding planes, were prepared by saw-cutting or polishing using either #100 or #600 grinding powders. Their basic friction angles were measured by direct shear testing, triaxial compression testing, and tilt testing. The direct shear tests and triaxial compression tests on the saw-cut, #100, and #600 ...
