Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a grinding mechanism applied to a new type of combined cement production system. Background Art

[0002] With the acceleration of the global industrialization process, the demand for building materials such as cement is growing, which requires the cement production system to have higher efficiency and more sophisticated technology. The grinding mechanism is a key link in cement production, and its performance improvement is directly related to the quality and production efficiency of cement.

[0003] The patent with the current publication number CN220048358U discloses a cement grinding machine, including a grinding chamber, a feed port, a discharge port, an abrasive cone and a first motor. Two feed ports are fixedly installed on the top of the grinding chamber, and a discharge port is fixedly installed on the bottom of the grinding chamber. An abrasive cone is arranged inside the grinding chamber, and the first motor can drive the abrasive cone to rotate. A screen is arranged inside the grinding chamber, a fixed block is installed at the bottom end of the screen, and a mounting rod is arranged inside the grinding chamber. Collision blocks are evenly installed on the outer surface of the mounting rod, and the collision blocks and the fixed blocks cooperate with each other. In actual use, the screen is set as an inclined surface to allow powder that meets the specifications to fall directly to the discharge port, and the remaining powder that does not meet the specifications rolls to the recovery chamber. The vibration generated by the cooperation between the fixed block and the collision block can not only speed up the filtration speed, but also prevent the screen from being blocked by raw material powder.

[0004] However, the above technology still has the following problems:

[0005] When grinding cement, the cement raw materials enter the grinding chamber through the feed port, which can easily cause accumulation inside the grinding chamber. Some raw materials are too large to be ground in the grinding chamber, or too large cement raw materials will slow down the grinding efficiency, and unqualified products after grinding cannot be screened.

[0011] Furthermore, the filtering and collecting assembly includes a filter screen fixed in the collecting chamber, a second discharge port provided on the side wall of the collecting chamber, and a storage vehicle arranged below the second discharge port.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] This grinding component used in the new combined cement production system can pre-treat the cement raw materials first to avoid the situation where the cement raw materials are too large to be fully ground in the grinding chamber, and to avoid the accumulation of cement raw materials. At the same time, it can also speed up the grinding efficiency and adjust the grinding particle size as needed. Unqualified products after grinding can also be collected and re-ground.

[0022] The grinding mechanism used in the new type of combined cement production system in the utility model is similar to the existing cement mill structure, such as the cement mill disclosed in the patent with publication number CN220048358U. The main improvement of the utility model is that by setting the pretreatment component 8, the lifting component 7 and the filtering and collecting component 9, the blockage is avoided, the grinding efficiency is accelerated, and the product quality is improved. Figures 1 to 5 As shown, when the grinding mechanism of the utility model applied to the new type of combined cement production system is used, the base 501 is first lifted by driving the hydraulic cylinder 703, and the base 501 moves upward along the slide 702 until the required cement particle size is adjusted. The staff pours the cement raw material into the feed port 2, and first grinds the cement raw material with the grinding roller 802 of the pretreatment component 8 to reduce the volume of the cement raw material, and then grinds the pretreated cement raw material through the grinding component 5.
