Malleable Iron Castings During the iron casting process, a manufacturer deposits molten iron and ferrous alloys into a mold. This material solidifies as it cools, ultimately hardening into a shape determined by the mold cavity. The casting process promotes important microstructural changes in cast metals. Iron Castings Casting today creates many commercially important products. …

Gears and mills. In early 2012, Ferry-Capitain, along with its Groupe CIF sister company, CMD, had been awarded a full scope of supply – girth gear sets, single-stage speed reducers, mill heads and trunnions – for large gear-driven 36 ft SAG and 26 ft ball mills, destined for two separate projects located in Russia and South America.

The gears are scheduled to be installed on the SAG mill at the mine in June 1995. They will be driven through clutches by two 9,000-hp, 176.5 rpm adjustable-speed synchronous motors made by GE Ltd ...

Casting defects like hot tears, porosity or shrinkage are excluded – resulting in a stronger and more reliable girth gear. When supplying ductile cast iron or cast-iron girth gears, we source the raw material from world-leading foundries – working …

A casting is best suited to complex shapes, custom or tailored chemistries, and to applications that are subject to multi-axial stresses. Casting buyers need to work closely with foundries at the design stage in order to insure that the design is able to take advantage of directional solidification.

Girth gears are now being used to drive ball and SAG mills having total installed power in excess of 17,000 kW (23,000 hp). The development of high-hardness materials suitable for these applications has resulted in the design and manufacturing of cast girth gears up to 350 HBW in steel and 340 HBW in ductile iron.

the mill builder can provide the gear designer with input power and output speed. The next step is the interface dimen-sions. Since the gear needs to turn the mill, it needs to have a bore larger than the mill outside diameter. The mill out-side diameter is a function of the grind-ing process selected. Autogenous mills
