Pressure frame of the ZGM mill

key word:Heat exchange element


Product description

The pressure frame is of the equilateral triangle structure, and the guide block is installed on it. The hydraulic loading system applies the force to the three corners of the pressure frame through the pull rod loading device. Hinge shaft seat can be installed at the bottom of pressure frame. The press frame is equipped with a guiding positioning structure to facilitate positioning and transferring tangential force during operation. The adjustment of clearance at the guide block shall be based on the alignment of the three pull rod axes, and the center of the tie rod plate shall prevail.


Key points of pressure frame design

1. the pressure frame has two types: welding and casting.

2. calculate bending stress.

3. the upper part of the design pressure frame shall consider non powder (this requirement is required for the internal design of the whole mill).

4. when designing coal mill later, it is necessary to consider making overall pressure frame (do not design into three parts).

5. the design basis of pressure frame is roller hinge contact, and the distance between hinge point and mill center is determined according to the standard of grinding disk and grinding roller.

6. the distance between the center of three tie rods and the center of mill is given as the design basis.

7. accurately determine the positioning dimension of the suspension device of the grinding roller.
