Sep 10, 2014· A ring motor is a complex machine that relies on its steel frames, the cores they support and the foundations (in the case of the stator frames) to achieve sufficient stiffness and is subject to static (thermal), cyclically dynamic and high-amplitude transient loads. Mills and motors are chalk and cheese in terms of complexity.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
dynamic response of foundations (Bhatia, 2006). Based on the scientific investigations carried out in the last few decades it has been established that it is not enough to base the design only on the vertical loads multiplied by a dynamic factor, even if this factor introduces a dynamic load many times greater than the original one.
By means of the open lifter diaphragm, the drying chamber integrated into the mill tube is separated from the grinding compartment. The steel grades used can easily withstand the up to 400°C hot gases found in the drying compartment. Construction of the diaphragm in Monobloc® version: supports the mill tube and resists deformation.
An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill …
