Abstract
An agitator mill for continuous fine grinding and dispersion of solid constituents suspended in a liquid has a grinding container, an agitator mounted for rotation in the grinding container, a charge of grinding elements within the grinding container, an inlet into the grinding container for flow of grinding stock to the charge of grinding elements and an outlet from the grinding container for flow of grinding stock away from the charge of grinding elements, pressure means for the application of pressure to the charge of grinding elements to vary the volume of the charge of grinding elements, the agitator having a shaft for rotating it, a drive bearing in the region of one end of the grinding container to permit rotation to be applied to the shaft in the region of a drive end of the shaft and an end bearing for the other end of the shaft, the said end bearing being disposed within the charge of grinding elements. Entry separator means prevent the passage upstream of grinding elements and is disposed upstream of the end bearing. The end bearing may be surrounded by a bearing housing e.g. better to protect it from grinding elements or e.g. for ease of cooling or lubrication or centra…
