Roll mill

Abstract

A main body (1) of the roll mill is provided with an intermediate roll (3) and a rear roll (4) disposed adjoining one another in front and behind, and the gap between the end portions thereof is closed with an end plate (5). A support bracket (7) movably retains the end plate (5) so that a lower end face (6) of the eridplate can slightly transfer in a direction of peripheries of the rolls (3, 4).The support bracket has a front pressing device (25) which always presses a front portion of the end plate (5) and a rear pressing device (26) which always presses a rear portion of the end plate (5).When a gap is formed between the periphery of the roll and the lower end face (6) of the end plate (5), the end plate slightly slants and this gap is automatically closed, since the end plate is pressed by the pressing devices.

Description

Technical field

[0001] The invention relates to a roller mill for grinding and dispersing processing materials in the manufacturing process of printing ink, paint, ceramics, medicine, food, electronic materials and other various products. Background technique

[0002] A plurality of rollers with different rotation speeds are arranged adjacent to each other, and a roller mill that uses the compression and shearing effects generated between the rollers to micronize the processing material for grinding or dispersion processing is widely used. For example, in a three-roll mill, three rolls, namely a front roll, a middle (center) roll, and a rear (supply) roll, are arranged adjacent to each other in the front-rear direction, and the rotation speed is sequentially increased in the order of the back roll, the middle roll, and the front roll. In addition, in order to prevent the treatment material from leaking between the ends of the rear roller and the middle roller, the gap between the...
