Embodiment Construction

[0037]Figure 1 schematically shows a grinding disc 2 which is rotated by a drive. The grinding material fed from the top or the side to the grinding channels 8 of the grinding discs is ground between the respective elastically pressurized grinding rollers 6 and the grinding channels 8 of the grinding discs 2 . The elastic pressurization is usually accomplished by a rocker rod and a hydraulic cylinder arrangement (not shown) cooperating with the rocker rod.

[0038] Each grinding roller 6 is normally driven only by contact friction with the grinding machine 7, which is provided on the grinding track, and has no separate drive. By means of a vane ring 4 (see Figure 2) and a supply conduit, a fluid, usually air, is provided. The fluid flowing through the blade ring 4 conveys the grinding material mixture consisting of fine and coarse material thrown from the grinding channel 8 by centrifugal force, and the material overmilled by the grinding rollers 6 is sent to a (not shown) s...

Abstract

The invention concerns a roller mill with a rotating pan, grinding rollers which roll over the pan and retaining devices designed to influence the movement between the grinding rollers of the material being ground. In order to raise the throughput of such a mill, while keeping capital costs low, the invention calls for efficient, wear-resistant retention devices to be located between the grinding rollers, each device comprising a rotating wall made up of one or more retention rollers. The retention rollers have retention faces which block the movement of material outwards, thus retaining it for further grinding. In a first embodiment, one retention face is the inwards-facing side of the retention roller. In another embodiment, the retention rollers are fitted with radially projecting rings, thus giving additional retention faces.

Description

technical field [0001] The present invention relates to a roller mill. Background technique [0002] Roller mills, also known as air-swept roller mills or roller bowl mills, are fed into the center of the disc with a stream of milled material that includes fresh material and coarser material from the classifier. For granular materials, the classifier is usually integrated with the mill. The stream fed into the center of the disc is moved by centrifugal force to the edge of the disc and into the blade ring surrounding the disc. In practice, the centrifugal force acting on the milled material depends on the diameter and rotational speed of the grinding discs. [0003] The production capacity of a roller mill basically depends on the effective grinding surface area, ie the number, size, and grinding speed of the grinding rollers used. This requires that the milled material should be fully fed to each roller. [0004] In principle, for the same predetermined geometry and the...
