Description

Technical Field

[0001] This utility model relates to the field of iron concentrate production technology, specifically a ball mill for iron concentrate production. Background Technology

[0002] Iron concentrate is a mineral powder obtained from iron ore through crushing, grinding, and beneficiation, primarily used in ironmaking and steelmaking. Iron concentrate has a high iron content, typically around 65%. Fine processing can improve the grade of iron ore and remove unwanted impurities. Ball mills are key equipment for further pulverizing materials after crushing. This type of mill contains a certain number of steel balls as grinding media within its cylinder. It is widely used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, and glass and ceramics, for dry or wet grinding of various ores and other grindable materials.

[0003] Currently, in practical applications of ball mills used for iron concentrate production, the addition of large particles increases the processing difficulty of the ball mill. This is because large particles require more time and energy to be crushed to the required particle size, which leads to a decrease in the production efficiency and output of the ball mill. Large particles may not be fully crushed, resulting in the presence of large particle impurities in the product, which affects the fineness and uniformity of the product and reduces product quality. Utility Model Content

[0004] The purpose of this invention is to provide a ball mill for the production of iron concentrate, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ball mill for producing iron concentrate, comprising a support, wherein an organic body is movably mounted on the top of the support;

[0006] A ball mill assembly, wherein the ball mill assembly is disposed on the right side of the support;

[0007] The ball mill assembly includes a rotating part and a ball milling part, both of which are located on the right side of the support.

[0008] A feeding assembly is disposed on the right side of the support;

[0009] The feeding assembly includes a feeding section and a water supply section, both of which are located on the right side of the support.

[0010] Preferably, the rotating part includes a motor base, a motor is fixedly installed inside the motor base, a gear one is fixedly installed at the output end of the motor, a gear two is provided on the right side of the support, a cylindrical shaft is fixedly installed inside the gear two, the motor base is located on the right side of the support, the gear one and gear two are meshed together, the left end of the cylindrical shaft is fixedly installed to the machine body, and the cylindrical shaft communicates with the inside of the machine body.

[0011] Preferably, the ball milling part includes a ball, the bottom of the machine body is provided with a blocking plate, the right side of the support is provided with a bracket, the right side of the support is provided with an outer tube, and the ball is disposed inside the machine body.

[0012] Preferably, the bracket is fixedly installed on the top of the motor base, a cylindrical shaft is movably installed inside the bracket, the left end of the outer tube passes through the cylindrical shaft and extends into the inside of the cylindrical shaft, the outer tube is movably installed between the outer tube and the cylindrical shaft, and the outer tube is fixedly installed on the top of the motor base.

[0013] Preferably, the feeding section includes a connecting frame, with a positioning column movably mounted on the top of the connecting frame via a snap-fit ​​connection. A feeding hopper is fixedly mounted on the top of the positioning column, and a grid plate is fixedly mounted inside the feeding hopper. A feeding pipe is movably mounted on the left side of the bottom of the feeding hopper via a snap-fit ​​connection. The material to be ball-milled is poured into the feeding hopper, and the material falls onto the grid plate. During this process, small materials smaller than the grid holes are smoothly guided into the feeding pipe by the guide plate and eventually enter the machine body for grinding. Larger materials remain on the top of the grid plate. At this point, the operator can easily remove the feeding hopper from the top of the connecting frame to collect the remaining large particles. Next, these large particles undergo centralized crushing pretreatment to ensure they reach a suitable particle size for ball milling. After pretreatment, these materials can be fed back into the ball mill for use. This operating procedure effectively reduces the processing burden of the ball mill and significantly improves grinding efficiency.

[0014] Preferably, the connecting frame is fixedly installed on the right side of the motor base, the top of the connecting frame is provided with a positioning hole, the positioning post is installed inside the positioning hole by snap-fit, the bottom of the inner wall of the feeding hopper is fixedly installed with a guide plate, the mesh plate is set in the middle of the feeding hopper, the feeding pipe is set inside the outer pipe, and one end of the feeding pipe passes through the outer pipe and extends to the top of the outer pipe.

[0015] Preferably, the water supply section includes a water tank, a pump body is fixedly installed at the bottom of the inner wall of the water tank, a water supply pipe is fixedly installed at the top of the pump body, and a filter screen is fixedly installed inside the water tank. An appropriate amount of water is injected into the water tank, and then the pump body is started. As the pump body operates, the water in the water tank is transported to the interior of the machine body through the water supply pipe for wet grinding of the material. During this process, the filter screen plays a crucial role, effectively trapping impurities in the water at its top, thereby preventing impurities from entering the interior of the machine body and ensuring that the quality of the material ball milling is not affected.

[0016] Preferably, the water tank is located on the right side of the support, one end of the water supply pipe passes through the water tank and extends to the top of the water tank, one end of the water supply pipe passes through the outer pipe and extends into the interior of the outer pipe, and one end of the water supply pipe is located at the top of the feed pipe.

[0017] This utility model provides a ball mill for the production of iron concentrate. It has the following beneficial effects:

[0018] (1) By setting up a feeding part, the material to be ball-milled is poured into the feeding hopper. The material falls on the top of the grid plate. The material smaller than the grid hole enters the feeding pipe under the action of the guide plate, and then enters the machine body through the feeding pipe. The larger material stays on the top of the grid plate. The feeding hopper can be removed from the top of the connecting frame to collect the larger material and perform centralized crushing and pre-treatment before putting it into the ball mill. This achieves the effect of reducing the burden on the ball mill and improving the grinding efficiency.

[0019] (2) By setting up a water supply part, water is injected into the water tank and the pump is started. The water in the water tank enters the machine body through the water supply pipe to wet grind the material. The filter screen can filter and separate the impurities in the water at the top of the filter screen, thereby preventing impurities from entering the machine body and affecting the ball milling quality of the material.
