Cast vs. Forged Steel: Key Differences

20-09-2017Steel casting is the process by which a metal is heated until it reaches a liquid state and then poured into a mold that shapes the desired product. Steel forging implies the application of mechanical forces to heated solid blocks of steel (such as ingots and/or billets) that are shaped into desired products permanently. STEEL FORGING VS. CASTING.

Choosing The Right Grinding Wheel

15-12-2000Another factor that affects the choice of wheel bond is the wheel speed in operation. Usually vitrified wheels are used at speeds less than 6,500 surface feet per minute. At higher speeds, the vitrified bond may break. Organic bond wheels are generally the choice between 6,500 and 9,500 surface feet per minute.

Ball Mill Liner Design

05-01-2016The liners are from 50 to 65 mm thick (2″ to 2.5″) with the waves from 60 to 75 mm (2.5″ to 3″) above the liners. The replaceable lifter bar design made of either metal or rubber in about the same design proportions can be used. There could be a loss in power with rubber particularly if the mill speed is faster than about 72% of

Ball Mills

Modern ball mills consist of two chambers separated by a diaphragm. In the first chamber the steel-alloy balls (also described as charge balls or media) are about 90 mm diameter. The mill liners are designed to lift the media as the mill rotates, so the comminution process in the first chamber is dominated by crushing.

Cast iron

Cast iron is a group of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks
