Description

Technical Field

[0001] The present application relates to the field of grinding technology, and in particular to an auxiliary limestone grinding device. Background Art

[0002] The main component of limestone is calcium carbonate. Limestone has a wide range of uses. It is an indispensable raw material in various sectors of the national economy and people's lives. It is also an important industrial raw material in metallurgy, building materials, chemical industry, light industry and agriculture. With the development of the steel and cement industries, the demand for limestone will further increase. Before limestone is used as an industrial raw material, it needs to be ground by a mill to make it a powdered raw material for easy use.

[0003] Since limestone raw materials usually contain particles of different sizes, including large lumps, medium-sized lumps and fine-grained stone powder, uneven particle size distribution will increase the difficulty of grinding, because large and small particles need to be processed at the same time, which may lead to reduced grinding efficiency and increased energy consumption.

[0004] Therefore, in view of the above situation, it is urgent to develop an auxiliary limestone grinding device to overcome the shortcomings in current practical applications. Summary of the invention

The first screening plate is provided with a large particle outlet, the second screening plate is provided with a small particle outlet, and the large particle outlet and the small particle outlet are staggered. The vibration motor is installed on the fixed frame for vibrating screening.

[0007] Furthermore, the feed assembly is provided with a feed hopper and a material distribution structure. The feed hopper is set as an open structure and is provided with a discharge port on one side. The material distribution structure is arranged close to the discharge port.

The vibrating screen assembly 3 is provided with a fixed frame 31, a first screen plate 32, a second screen plate 33 and a vibration motor 34. The four sides of the fixed frame 31 are installed on the frame 1 through an elastic structure 35. The first screen plate 32 and the second screen plate 33 are arranged on the fixed frame 31 with an upper and lower interval, and the first screen plate 32 is located above the second screen plate 33. The first screen plate 32 is provided with a large particle outlet 321, the second screen plate 33 is provided with a small particle outlet 331, and the large particle outlet 321 and the small particle outlet 331 are staggered. The vibration motor 34 is installed on the fixed frame 31 for vibrating screening.

[0028] This embodiment has a simple structure and a reasonable design. By setting the vibrating screening assembly 3, the limestone raw material is screened for particle size before grinding to reduce the particle size difference, thereby improving the grinding effect and efficiency and playing an auxiliary grinding role.

[0029] When in use, it is set at the feed port of the limestone grinding device, and the small particle material outlet 331 is connected to the feed port of the limestone grinding device to supply small particle materials. The large particle material outlet 321 is staggered and can be connected to an external crushing mechanism. After crushing, it is transported to the vibrating screen assembly 3 in this embodiment for screening, thereby achieving effective screening of the limestone particle size and performing a better auxiliary role in limestone grinding.

[0030] In some embodiments, the feed assembly 2 is provided with a feed hopper 21 and a material separation structure. The feed hopper 21 is provided as an open structure and has a discharge port on one side. The material separation structure is provided close to the discharge port.

[0031] Specifically, the material distribution structure is provided with a material distribution plate 22 and a driving motor 23. The material distribution plate 22 is rotatably arranged in the feed hopper 21 and arranged close to the discharge port. The driving motor 23 is installed on the frame 1 and is driven and connected to the material distribution plate 22 through a gear structure 24.

[0032] More specifically, the material dividing plate 22 is provided with a plurality of material dividing teeth 221 .

[0033] In this embodiment, a material dividing structure is set in the feed hopper 21, specifically a material dividing plate 22 with material dividing teeth 221, and it is driven to rotate by a driving motor 23. Such a setting can break up the limestone raw materials when feeding, so as to facilitate better vibration screening of the vibrating screen assembly 3.

[0034] In some embodiments, a plurality of screening material blocking rods 322 are evenly spaced apart on the first screening material tray 32 .

[0035] In this embodiment, the screening material baffles 322 arranged at intervals can form intervals for controlling the particle size, so that materials larger than the gaps are screened out, and small materials fall to the second screening material plate 33 and enter the limestone grinding mechanism through the small particle material outlet 331 for better grinding.

[0036] On the basis of the above embodiment, a rolling sleeve is provided on the outer side of the screening material stop rod.

[0037] In this embodiment, by providing a rolling sleeve, the material screening process can be provided with a certain degree of rotation along with the vibration, thereby avoiding the limestone raw material from getting stuck, thereby achieving a smoother material screening effect.

[0038] In some embodiments, the elastic structure 35 is configured as a spring.

[0039] In this embodiment, by setting it as a spring, specifically a spring with a certain strength, during the vibration process, the entire fixing frame 31 has a certain shaking property, so as to achieve a better screening effect.
