Abstract
Description
Technical Field

[0002] Grinding in cement technology refers to the process of finely grinding clinker and admixtures to make them into cement powder. The purpose of grinding is to increase the surface area of clinker, improve the activity of cement, and thus improve the strength and hardening speed of cement. The traditional combined grinding method used in the current workshop for clinker and admixtures cannot fully grind the clinker particles and the strength cannot be fully exerted, resulting in high clinker consumption. Therefore, a roller press structure for adjusting the fineness of clinker is proposed for use.
[0003] The existing Chinese utility model patent with reference announcement number: CN213996021U discloses a roller pressing structure of a roller press for preparing cement raw materials, which belongs to the technical field of cement production. In this technical scheme, two mounting frames are included, a material collecting frame is installed at the bottom of the mounting frame, a baffle is fixedly installed on the side of the material collecting frame, a quick clamping device is installed between the material collecting frame and the mounting frame, and two cleaning devices are symmetrically fixedly installed on the material collecting frame. The advantages are: the utility model installs a material collecting frame under the mounting frame to collect the materials leaking from the edge of the pressure roller to prevent them from falling on the equipment, thereby protecting the equipment from being affected by the leakage of materials. At the same time, the material collecting frame is installed by the clamping method of the limit block, and the installation and disassembly are very convenient, which is convenient for replacing and cleaning the material collecting frame. The utility model installs a cleaning device on the material collecting frame, and uses the brush on the movable plate to fully contact with the rotating rod, so that the leaked materials falling on the rotating rod can be quickly and timely cleaned up, ensuring the normal rotation of the rotating rod.
[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that the clinker particles could not be fully ground and the strength could not be fully exerted, resulting in a high clinker consumption. In addition, the clinker with larger solids could not be screened during the clinker grinding process, resulting in insufficient surface area of the clinker, which affects the activity of the cement. The existence of these problems has affected the use of the device. Utility Model Content
