Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to an adjustable grinding device. Background Art

[0002] The cement processing process only involves two grindings and one burning. By grinding large-sized materials into small-sized materials, the preparation and processing of cement is facilitated.

[0003] Publication number CN214863947U was retrieved and disclosed an environmentally friendly cement grinding device, which includes a processing box for loading and grinding the cement to be processed; a crushing assembly, which is fixedly mounted on the processing box and is used to crush the cement to be processed; and a base, which is located below the processing box and is fixedly connected to the processing box and is used to load the processed cement. This environmentally friendly cement grinding device, when in use, puts the processed cement into the processing box, and is squeezed by the squeezing rollers in the crushing assembly. Under the action of the squeezing force, the crushing effect is better, and the gap between the two sets of squeezing rollers is smaller, so that the space where the cement itself is located is also smaller, and there will be no situation where it cannot be squeezed, so the crushing of the material is better.

[0004] When CN214863947U is used, the grinding effect is improved by squeezing the material through the squeezing roller, but there are still some shortcomings when using it. The material passing gap between the two squeezing roller supports cannot be adjusted. Different raw materials and process parameters require different roller pressing gaps. The inconveniently fixed gap leads to high pressure and loss when grinding hard materials. The inability to adjust the gap limits the flexibility of product particle size control. For this reason, we propose an adjustable grinding device to solve the existing problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 4 As shown, the utility model proposes an adjustable grinding device, including a machine body 2, a motor 25, a grinding roller 2 12, a mounting plate 10 and a brush plate 18, a grinding roller 2 12 and a grinding roller 1 9 are arranged inside the machine body 2, both ends of the grinding roller 1 9 are rotatably mounted inside the machine body 2, a travel port 6 is opened inside the front and rear ends of the machine body 2, one end of the grinding roller 2 12 is located inside the travel port 6, the grinding roller 2 12 and one end of the grinding roller 1 9 are controlled by the motor 25 and the motor 1 3, and the output shaft ends of the motor 25 and the motor 1 3 are connected to the grinding roller 2 12 and the grinding roller 1 9, and the outer walls of both ends of the grinding roller 2 12 are rotatably sleeved. There is a mounting sleeve 17, mounting plates 10 are provided inside the front and rear ends of the body 2, a slide groove 13 is opened inside the mounting plate 10, a slider 14 is provided at the lower end of the mounting sleeve 17, and the lower end of the slider 14 is slidably installed inside the slide groove 13, a hydraulic rod 7 is provided at one end of the body 2, the telescopic end of the hydraulic rod 7 is slidably installed with the body 2 through a sealing sleeve, and the telescopic end of the hydraulic rod 7 is connected to the mounting sleeve 17, the outer wall of the motor 2 5 is sleeved with a sleeve, a slide seat 4 is provided at the front end of the body 2, the sleeve is slidably installed inside the seat, a feed hopper 1 is provided inside the upper end of the body 2, and guide plates 8 are provided inside both sides.

[0023] Based on the implementation steps of Example 1: the hydraulic rod 7 drives the mounting sleeve 17 to move laterally, driving the grinding roller 12 to move laterally. After the laterally moved grinding roller 12 is adjusted, the gap between the grinding roller 19 and the grinding roller 12 is adjusted. When grinding materials of different specifications and process requirements, the gap between the grinding roller 19 and the grinding roller is effectively adjusted, which avoids the situation where the two fixed grinding rollers cannot effectively process the changed material grinding requirements when the material fineness requirements change.
