TECHNICAL FIELD
[0001] The present application relates to the technical field of ball mill equipment, and particularly relates to a ball mill discharge lining plate with guide plates. BACKGROUND
[0002] In the field of ball mills, ball mills are important equipment for material grinding and are widely used in many industries such as mining, building materials and chemical industry. In the discharge process of the traditional ball mill, there are some problems to be solved. The discharge particle size control is not accurate enough. When the traditional ball mill discharges, the particle size of the material is not uniform, and part of the material may be discharged without reaching the ideal grinding degree, while part of the material may be overground, which not only affects the product quality, but also causes energy waste. In cement production, if the particle size of the cement particles does not meet the standard, the setting time, strength and other properties of the cement will be affected, and then the quality of the construction engineering will be affected. The discharge efficiency is low. Due to the lack of a reasonable discharge guide structure, the material is prone to blockage and accumulation during the discharge process, which leads to slow discharge speed and reduces production efficiency. In the process of ore dressing in the mine, the ball mill discharge is not smooth, which will affect the continuity of the whole ore dressing process and increase the production cost.
[0003] For the related technologies in the above, the inventors find that there are the following defects: Many ball mills on the market lack effective synchronous screening mechanisms during the grinding process. Usually, screening is performed only after the completion of the whole grinding process, which can easily lead to overgrinding of part of the material and failure to reach the ideal particle size of part of the material. Some old ball mills only rely on grinding time to control particle size and do not timely screen qualified materials during the discharge process, so that the product particle size distribution is uneven and the product quality is affected. Moreover, this method also wastes a large amount of energy in unnecessary grinding process. CONTENT OF THE INVENTION

[0024] The C-shaped ring 315 is movably sleeved on one side of the inner sleeve 311, and the shape of the discharge chute 316 is the same as that of the second discharge hole 313.
[0025] Each side of the stop block 312 away from the inner sleeve 311 is fixedly connected with an arc-shaped baffle, and the cavity formed by the arc-shaped baffle, the stop block 312 and the inner sleeve 311 is in communication with the discharge chute 304.
[0026] The guide plate body 305 is obliquely arranged in the inner part of the discharge chute 304, and the guide plate body 305 and the screening rod 306 jointly form a screen mesh, and the screening mesh is 40 meshes.
[0027] The buffer lining plate 307 is fixedly installed on the top of the discharge lining plate 303, the width of the buffer lining plate 307 is smaller than that of the discharge lining plate 303, and the buffer lining plate 307 is arranged on the right side.
[0028] The side baffle 314 is fixedly connected to one side of the second bearing seat 5, and the side baffle 314, the inner sleeve 311, the C-shaped ring 315 and the discharge chute 316 jointly form a discharge assembly, and the discharge chute 316 is a discharge port.
[0029] It needs to be further explained that:
[0030] Firstly, the ball mill assembly is responsible for the grinding work of the material. The ball mill barrel 301 serves as the main body, providing space for grinding, containing materials and grinding media inside, and making them interact through rotation to achieve material grinding. The ball mill lining plate 302 is installed inside the barrel, not only protecting the barrel from impact and wear caused by materials and grinding media, prolonging the service life of the barrel, but also changing the motion trajectory of the grinding media and the material, increasing the collision frequency, improving the grinding efficiency, and making the material more fully ground to the appropriate particle size to meet the production requirements.
[0031] Secondly, the assembly assumes the function of discharging guide. The discharge liner 303 is located at the discharge end of the ball mill cylinder, connecting the cylinder with the subsequent discharge components, guiding the ground material into the discharge chute 304. The discharge chute 304 serves as a channel for the material to flow out of the cylinder, ensuring the orderly outflow of the material. The guide vane body 305 is inclinedly arranged in the discharge chute, guiding the flow direction of the material on one hand, and constituting a screen with the screening rod 306 on the other hand, preliminarily screening the material, separating the qualified particle size material in advance, avoiding excessive grinding, and improving production efficiency. The buffer liner 307 is installed on the top of the discharge liner, reducing the impact of material discharge, protecting the equipment, and further screening the material through the screening hole 308 on the top, ensuring the quality of discharge.
[0032] Finally, the ball mill assembly realizes fine control of discharge. The outer sleeve 309 connects the ball mill cylinder, and cooperates with the inner sleeve 311 to guide the further outflow of the material. The first discharge hole 310 and the second discharge hole 313 are respectively arranged on the outer sleeve and the inner sleeve, controlling the discharge position and flow of the material. The cavity formed by the stop block 312 and the arc-shaped baffle is in communication with the discharge chute, playing the role of flow guiding and blocking. The side baffle 314, the C-shaped ring 315 and the discharge chute 316 jointly constitute the discharge assembly, the side baffle limits the discharge direction of the material, the C-shaped ring is sleeved on the inner sleeve to assist the discharge, and the discharge chute serves as the final discharge port, ensuring the stable and uniform discharge of the material, meeting the requirements of production process.
[0033] The working principle of the above embodiment is as follows:
[0034] Firstly, the material enters the ball mill cylinder 301 in the ball mill assembly 3 through the feed pipe 2. The ball mill cylinder 301 is internally provided with grinding media. When the ball mill cylinder 301 starts to rotate under the drive of the gear 4, the material and the grinding media are driven in the ball mill cylinder 301. Due to the presence of the ball mill liner 302, the movement track of the grinding media and the material will be changed. They will be constantly lifted and dropped by the ball mill liner 302, so that the material is squeezed, impacted and ground between the grinding media, and is gradually crushed into smaller particles.
[0035] Secondly, the ground material will move to the discharge end of the barrel 301. When the material reaches the discharge liner 303, it will flow out through the discharge chute 304. In the discharge chute 304, the guide plate body 305 guides the flow of the material. The inclined arrangement of the guide plate body 305 allows the material to flow along its surface. At the same time, the sieve screen formed by the guide plate body 305 and the sieve rod 306 performs a preliminary screening of the material. The material meeting the particle size requirement of 40 mesh can continue to advance through the sieve screen, while the material with larger particle size is retained on the sieve screen and may be returned to the barrel 301 for further grinding. The buffer liner 307 is located on the top of the discharge liner 303 and can buffer the impact force of the material during the discharging process. When the material passes through the buffer liner 307, the top sieve hole 308 also screens the material, further ensuring that only the material with appropriate particle size can pass through.
[0036] Finally, the material then enters the discharge assembly part composed of the outer sleeve 309, the inner sleeve 311, etc. The first discharge hole 310 on one side of the outer sleeve 309 and the second discharge hole 313 on one side of the inner sleeve 311 work together to control the flow path of the material out of the outer sleeve 309 and the inner sleeve 311. The cavity formed by the stop block 312 and the arc-shaped baffle communicates with the discharge chute 304 and plays a guiding role, allowing the material to smoothly enter the inner sleeve 311 and subsequent components. The side baffle 314 is fixed on one side of the second bearing seat 5 and, together with the inner sleeve 311, the C-shaped ring 315, and the discharge chute 316, forms the discharge assembly. The C-shaped ring 315 is movably sleeved on one side of the inner sleeve 311, and the discharge chute 316 serves as the final discharge port. Through the coordinated action of these components, the discharge direction and flow of the material are accurately controlled, allowing the material to stably and uniformly flow out of the equipment.
[0037] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made in terms of structure, shape, and principle based on the present application should be covered within the protection scope of the present application.
