AI Technical Summary
The existing ball mill feed pipeline is deformed and leaked due to the direct impact of slurry and steel balls, which affects the continuous operation of the equipment. In order to avoid failure, one is required to operate and another to standby, which increases maintenance costs.
A buffer tank is installed so that the slurry and steel balls enter the buffer tank separately before being sent to the steel ball feeding pipe. The buffer tank is divided into a feed zone and a discharge zone by an overflow plate, forming a slurry sedimentation layer to buffer the impact and reduce damage to the buffer tank. The inlet of the ball mill feed pipe is designed to be higher than the bottom plate of the discharge zone to form a slurry sedimentation layer and avoid impact.
This effectively prevents deformation and leakage in the ball mill feed pipeline, ensuring continuous and stable operation of the grinding system, reducing maintenance costs and improving equipment operating efficiency.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the field of mill feeding equipment, and in particular relates to a ball mill feeding buffer system. BACKGROUND
[0002] The ore grinding operation is that the ore pulp is first divided by a cyclone and then sent to a ball mill, the ore pulp from the cyclone and the steel balls from the steel ball adding pipe are simultaneously sent to the feeding pipe of the ball mill, and then sent to the ball mill by the feeding pipe. At present, the dividing pipe of the cyclone and the steel ball adding pipe are directly connected to the feeding pipe, which causes great impact on the feeding pipe by the ore pulp from the cyclone dividing pipe and the steel balls, resulting in deformation and leakage of the feeding pipe, especially the leakage at the connection between the cyclone dividing pipe and the steel ball adding pipe is more serious. Once leakage occurs, not only the environment is polluted, but also the equipment needs to be stopped for maintenance, which greatly affects the continuous operation of the equipment. In addition, in order to ensure the continuous operation of the equipment and avoid starting due to failure, one cyclone is started and one is standby, and the feeding pipe is connected to the two cyclone dividing pipes, which causes a large impact surface of the ball mill feeding pipe, which further aggravates the deformation and leakage of the feeding pipe. SUMMARY

[0017] In order to make the purpose, technical scheme and advantages of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the drawings, so as to facilitate the understanding of the skilled in the art.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0020] like Figure 1 As shown (attached) Figure 1 (The diagram shows the internal structure of this utility model when the structural part is cut open). The ball mill feed buffer system includes a buffer box 2, a hydrocyclone, a steel ball and ball tube 6, a ball mill feed pipe 4, and a ball mill.
[0021] The buffer tank 2 is a sealed cavity structure consisting of an outer wall, a bottom plate, and a top plate. The hydrocyclone's diverter pipe 1 and the steel ball feeding pipe 6 are connected to the buffer tank 2, and the ball mill feed pipe 4 is connected between the buffer tank 2 and the ball mill. The slurry from the hydrocyclone's diverter pipe 1 and the steel balls added from the steel ball feeding pipe 6 first enter the buffer tank 2, and then are transported from the buffer tank 2 to the ball mill via the ball mill feed pipe 4.
[0022] An overflow plate 5 is provided at the bottom of the buffer tank 2. The overflow plate 5 is vertically fixed to the bottom plate of the buffer tank 2, dividing the buffer tank 2 into a feeding zone and a discharging zone. The hydrocyclone's diverter pipe 1 is inserted into the feeding zone from the top of the buffer tank 2, and the inlet pipe of the ball mill feed pipe 4 is connected to the bottom of the discharging zone of the buffer tank 2. By setting the overflow plate 5, a slurry sediment layer (or a slurry and steel ball mixture sediment layer) is formed at the bottom of the feeding zone of the buffer tank 2. When the slurry transported from the hydrocyclone's diverter pipe 1 enters the buffer tank 2, the sediment layer buffers the slurry, avoiding or reducing the impact of the slurry and steel balls on the buffer tank 2, thereby avoiding or reducing the damage to the buffer tank 2 caused by the impact.
[0023] The inlet of the ball mill feed pipe 4 is higher than the bottom plate of the discharge zone of the buffer tank 2, but lower than the overflow plate 5. This design allows a slurry sedimentation layer or a mixture of slurry and steel balls to form at the bottom of the discharge zone of the buffer tank 2, which also reduces or avoids the impact of steel balls or slurry on the buffer tank. Simultaneously, the lower height of the ball mill feed pipe 4 compared to the overflow plate 5 ensures a consistent slurry height difference between the feed and discharge zones, thanks to the overflow plate 5. This, combined with the flow of the slurry through the ball mill feed pipe 4, prevents excessive sedimentation at the bottom of the buffer tank 2, thus avoiding blockage at the inlet of the ball mill feed pipe 4 due to an excessively thick sedimentation layer and ensuring normal slurry transport.
[0024] The steel ball adding ball pipe 6 is inserted into the feeding area or discharging area of the buffer tank 2 from above, and the steel ball can be added from the feeding area or the discharging area.
[0025] The bottom of the buffer tank 2 is provided with a base 3, and the material of the buffer tank 2 is a steel plate.
[0026] As a preferred solution, the inner wall of the feeding area of the buffer tank 2 is provided with a lining plate, and the lining plate can also be provided on the inner wall of the buffer tank 2, and the lining plate is preferably provided with a rubber pad, which plays a role of buffering impact by setting the lining plate.
[0027] Compared with the structure that the shunt pipe 1 and the steel ball adding ball pipe 6 of the cyclone are directly communicated to the ball mill feeding pipe 4, the maintenance cost caused by the through hole of the ball mill feeding pipe 4 is greatly reduced, the equipment operation rate is improved, the equipment maintenance cost is reduced, and the equipment operation efficiency is improved.
[0028] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the utility model and are not limited, although the utility model has been described in detail through the above preferred embodiments, but those skilled in the art should understand that various changes can be made in form and details without departing from the range defined by the claims of the utility model.
