Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ball mill equipment, and particularly relates to a ball mill device capable of automatically adding balls. BACKGROUND

[0002] The ball mill is a kind of crushing equipment widely used in industrial production, and plays a vital role in many fields such as mining, metallurgy, building materials and chemical industry. The working principle of the ball mill is that the rotation of the cylinder causes the collision and friction between the material and the grinding medium such as steel balls in the cylinder, so as to realize the crushing and grinding of the material.

[0003] In the operation process of the traditional ball mill, the steel balls as important grinding medium will gradually wear and consume with the increase of the use time. In order to ensure the grinding efficiency and effect of the ball mill, it is necessary to add steel balls to the ball mill regularly. However, the traditional ball adding method mostly adopts manual operation, that is, the workers manually add steel balls to the ball mill according to experience and regular inspection. The time interval of manual ball adding is difficult to accurately grasp, which may lead to the situation that the steel balls are not added in time or are added in excess. If the steel balls are not added in time, the number of steel balls in the ball mill will be insufficient, which will affect the grinding effect and production efficiency. If the steel balls are added in excess, the energy consumption and wear of the equipment will be increased, and even the normal operation of the equipment will be affected.

[0032] It needs to be further explained that:

[0033] The automatic ball adding mechanism 5 is the core component for realizing the automatic ball adding of the ball mill. In the working process of the ball mill, the steel balls as the grinding medium will continuously collide and rub with the materials, thereby gradually being worn and consumed. If the steel balls cannot be timely supplemented, the number and gradation of the steel balls in the ball mill will change, thereby affecting the grinding effect and efficiency of the materials. The mechanism can automatically and timely add the steel balls into the first ball mill cylinder 2 and the second ball mill cylinder 3 according to the running condition of the ball mill, so as to ensure that there are sufficient number and appropriate specifications of steel balls in the ball mill to participate in the grinding work, thereby ensuring the continuous and stable running of the ball mill and effectively improving the production efficiency.

[0034] The automatic ball adding mechanism 5 has the function of accurately distributing steel balls. The ball mill partition plate 501, the steel ball distribution pipe 509 and other components in the automatic ball adding mechanism 5 cooperate with each other, so that the steel balls can be accurately distributed into the two ball mill barrels. The first servo motor 503 fixed by the motor fixing plate 502 drives the first gear 504 and the second gear 505 to rotate, and then drives the steel ball distribution pipe 509 to rotate, so that the steel balls can enter the corresponding barrel according to the preset path. At the same time, the design of the ball adding hole 507 and the ball adding groove 508 also provides a channel for the smooth entry of the steel balls, ensuring the uniform distribution of the steel balls in the two barrels, which helps to improve the grinding uniformity of the ball mill for the materials.

[0035] The automatic ball adding mechanism 5 also has certain control function. The spiral lifting plate 511 on the rotating shaft 510 can lift the steel balls from the bottom to a certain height, facilitating the conveying of the steel balls. The ball adding bin 513, the first ball adding pipe 514, the second ball adding pipe 516, the first ball storage box 515 and the second ball storage box 517 constitute a steel ball storage and conveying system. The electric control blocker 519 and the blocking rod 520 can control the outflow of the steel balls according to the needs, realize the accurate control of the ball adding amount, and meet the requirements of different materials and processes for the steel ball adding amount.

[0036] The working principle of the above embodiment is as follows:

[0037] Firstly, the driving device 4 is the power source for the operation of the whole ball mill device. When the equipment is started, the driving device 4 starts to work, and the gear at the top of the driving device 4 is tightly engaged with the gears on the outer walls of the first ball mill barrel 2 and the second ball mill barrel 3. Under the action of gear transmission, the driving device 4 transmits power to the two ball mill barrels, so that they start to rotate around the shaft. The rotation of the barrel provides the necessary motion condition for the grinding of the material, and the material rolls in the barrel with the rotation of the barrel.

[0038] Secondly, with the continuous rotation of the first ball mill barrel 2 and the second ball mill barrel 3, the material put into the barrel is lifted to a certain height under the joint action of centrifugal force and friction. When the material reaches a certain height, it will fall freely under the action of gravity. At this time, the steel balls in the barrel will also move with the rotation of the barrel. Strong collision and friction will occur between the material and the steel balls and between the steel balls, which can gradually grind and crush the material to realize the preliminary processing of the material.

[0039] Then, during the operation of the ball mill, the steel balls will gradually decrease due to wear, breakage and other reasons, and need to be supplemented in time. The automatic ball adding mechanism 5 starts to play a role. The first ball storage tank 515 and the second ball storage tank 517 serve as the storage container of the steel balls, and store enough steel balls inside. When the ball needs to be added, the electric control blocker 519 receives a signal, controls the blocker rod 520 to rise, so that the steel balls can pass through the ball outlet hole 518 into the first ball adding pipe 514 and the second ball adding pipe 516, and then the steel balls enter the ball adding bin 513.

[0040] Next, the second servo motor 512 starts to drive the rotating shaft 510 to rotate, and the spiral lifting plate 511 fixed on one side of the rotating shaft 510 also rotates. The rotation of the spiral lifting plate 511 lifts the steel balls in the ball adding bin 513 upwards. At the same time, the first servo motor 503 starts to work, and its output end drives the first gear 504 to rotate. The first gear 504 is engaged with the second gear 505, and the second gear 505 drives the steel ball distribution pipe 509 to rotate, guiding the lifted steel balls to the appropriate position, and preparing for the steel balls to enter the ball mill cylinder.

[0041] Finally, the steel balls enter the ball adding groove 508 inside the ball mill partition plate 501 through the steel ball distribution pipe 509. Since the ball adding groove 508 has a certain downward inclination and is connected with the ball adding hole 507, the steel balls will roll along the ball adding groove 508 under the action of gravity, and finally enter the first ball mill cylinder 2 and the second ball mill cylinder 3 through the ball adding hole 507 respectively, so as to realize the automatic ball adding process. The newly added steel balls continue to participate in the grinding of the material, ensuring the stability of the number and gradation of the steel balls in the ball mill, and maintaining the normal and efficient operation of the ball mill.

[0042] The above are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
