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...

Embodiment Construction

[0018] The present invention can be applied to various roller mills that use multiple rollers with different rotation speeds to grind and disperse processing materials. In the embodiment shown in the figure, there are three rollers adjacent to each other in the front and rear directions. Of three roller mills. Reference figure 1 , 2 , The front roller 2, the middle (center) roller 3, and the rear (supply) roller 4 are adjacently arranged on the roller mill main body 1 in the front-rear direction, and the rotation speed of each roller is from the rear roller 4 to the front roller 2 side in order increase.

[0019] A baffle plate 5 is provided between the ends of the aforementioned rear roller 4 and the middle roller 3 to block the gap between the rollers. The lower end of the baffle 5 is formed with a lower end surface 6 having curved surfaces 6a, 6b that are curved corresponding to the peripheral surfaces of the rear roller 4 and the middle roller 3 at the front and rear. The ba...
