· Some grinding wheels provide deeper cutting power and will allow you to take off a full 1/8″ in one pass. The difference will be in smoothness. You can expect the deeper you grind in a single pass the rougher your concrete will look. If you are planning to resurface with fresh concrete, this may not be a big issue. If you are planning to put down new flooring right away, you want a smooth ...

· GRINDING Grinding can be done in two stages •Ball Mill –Consists of cast iron drum containing iron and steel balls of different sizes. The principle used in ball mill s impact and shear produced by large no. of tumbling and rolling balls. •Tube Mill –Ball mill grinding is followed by tube mill grinding. Tube mill is conical at the discharge end with separate inlet and outlet. –Slower ...
Finishing is accomplished by expanding abrasive stones of suitable grit and grade against the work surface. The stones are rotated and reciproed in the part with hone abrasive under controlled pressure. Combining rotation and reciproion produces a crosshatch pattern in the surface of the part being honed. Lapmaster Honing Machines Perform Three Operations. First, it is a stock removal ...
Ball Mill: A large steel cylinder containing steel balls into which crushed ore is fed. The ball mill is rotated, causing the balls to cascade and grind the ore. Bench: Horizontal steps/increments mined as an open pit progresses deeper. Bull market : Term used to describe financial market conditions when share prices are going up. Byproduct : A secondary metal or mineral product recovered in ...
