[0002] High-pressure roller mills are widely used in the crushing of ores in cement raw materials in the construction industry. Since high-pressure roller mills implement quasi-static crushing, this quasi-static crushing method saves energy compared to impact crushing, has better crushing effect, and less roller wear.

[0003] The crushed ore will form cakes and lumps due to the high pressure. In order to improve work efficiency, a high-pressure roller mill has appeared in the prior art that can directly break up the caked materials after crushing. An inclined discharge barrel is directly set at the bottom of the roller mill chamber to directly transport the crushed materials to the breaking device for breaking. However, under this structure, the cakes are only transported by their own gravity, the speed is slow, and the materials are prone to accumulation. Therefore, we propose a high-pressure roller mill for construction cement processing. Utility Model Content

After the crushed cement raw materials fall on the rotating disk 914, they move with the rotation of the rotating disk 914 and collide with the protrusion 915, so that the agglomerated cement raw materials can be fully broken up and moved to the inner center position of the rotating disk 914 under the influence of gravity, and then fall through the rotating cylinder 913. The movable door 932 is a detachable plate. During installation, the operator opens the movable door 932, and the operator can install the internal belt through the groove 931. When the rotating motor 923 fails, the maintenance personnel remove the rotating motor 923 by removing the installation side plate 922, and then take it out through the groove 931.
