Despite these drawbacks in the case of the grinding of the tough or very tough materials one obtained smaller wears by using the balls made of manganese steel
. In the case of the use of balls made of austenitic manganese steel
, one remarked the advantage of the smaller wears and tears with a reduced specific consumption of grinding bodies, whereas the average productiveness increased due to a constant ball loading in the mill.
Abstract: This paper presents some data experimentally determinated in the drilling process of the manganese steels
T70Mn140 and T105Mn120.
* Thinner plates - the thickness of the magnetic plates is 70-80% of that of the manganese steel
Filter Castalloy Div., a medium-size job shop in Waukesha, Wisconsin, produces manganese steel
and white and Ni-hard iron compounds for heat treating, asphalt paving, coal handling and concrete pipe manufacturing equipment.
The machine also features an 8-bladed, TruBlast wheel unit, two rear access doors for unrestricted access to the mill, manganese steel
roof liners and cast barrel head liners, and a screw conveyor to aid in abrasive reclaim.
The system also features: a heavy-duty, hi gh-capacity elevator; cast steel, directdrive motors on the blast wheel and gear reducers; and a one-piece cast manganese steel
blast wheel housing.--USF Surface Preparation Group
