Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mill equipment, and particularly relates to a ball adding device for a ball mill. Background Art
[0002] As a commonly used material grinding equipment, mills are widely used in many fields such as mines and building materials. With the development of technology, mill equipment shows a trend of being large-scale, large-sized and heavy-duty. As a result, the processing capacity of mills is increasing day by day, and more and more grinding media such as steel balls or ceramic balls need to be added every day. At present, the main way to add balls to mills in most ore dressing plants is still manual addition, which increases the workload of workers, raises the risks in the transfer process and the ball adding process. At the same time, the uneven manual ball adding will also cause fluctuations in production process indicators and an increase in mill energy consumption. On the other hand, most ore dressing plants also have multiple mills in use, and the existing automatic ball adding device is that one ball adding machine only adds balls to one mill. For multiple mills to add balls, multiple adding devices need to be used, which will occupy more space and resources. Therefore, a device that can add balls to multiple mills is needed to meet the large-scale, large-sized and intelligent development of mill equipment. Content of the Utility Model

The ball storage bin group is arranged on the upper side of the belt conveyor. At the lower discharge port of each ball storage bin, there is respectively an openable and closable sector gate. Along the conveying direction of the belt conveyor, there are multiple plough-type dischargers arranged downstream of the ball storage bin group; the plough-type discharger includes a main shaft, a main shaft bracket, a scraper and a driving motor. The main shaft is horizontally installed on the upper side of the belt conveyor in the front-back direction and left-right inclined through the main shaft bracket. One end of the main shaft is provided with a driving motor. The scraper is installed on the main shaft along the axial direction. After the scraper rotates, it will fit with the upper surface of the belt conveyor. At the downstream end of each scraper along the conveying direction of the belt conveyor, there is respectively a discharge funnel, and the discharge funnels are respectively connected to ball mills. The control box controls the movement of the sector gate and the driving motor.

[0015] It should be noted that the present utility model provides the following specific implementation schemes for the ball mill ball adding device:
[0016] Such as Figure 1-2As shown in the figure, the utility model provides a ball adding device for a ball mill, which includes a ball storage bin group composed of a plurality of arranged ball storage bins 1, a control box, and a belt conveyor 2 for transporting in the left-right direction. The ball storage bin group is arranged on the upper side of the belt conveyor 2. At the lower discharge ports of each ball storage bin 1, there are respectively provided openable and closable sector gates 5. Along the conveying direction of the belt conveyor 2, there are arranged a plurality of plough-type trippers 7 downstream of the ball storage bin group; the plough-type tripper 7 includes a main shaft 71, a main shaft support 74, a scraper 72, and a driving motor 73. The main shaft 71 is horizontally and obliquely installed on the upper side of the belt conveyor 2 in the front-rear and left-right directions through the main shaft support 74. One end of the main shaft 71 is provided with the driving motor 73. The scraper 72 is axially installed on the main shaft 71. The driving motor 73 drives the main shaft to rotate actively, thereby driving the scraper 72 to rotate. After the scraper 72 rotates, it will fit with the upper surface of the belt conveyor 2 to block the transportation channel of the belt conveyor 2. Along the conveying direction of the belt conveyor 2, at the downstream ends of each scraper 72, there are respectively provided discharge funnels 3, and the discharge funnels 3 are respectively connected to the ball mill 4. The control box controls the opening and closing of the sector gate 5 to control the on-off of the discharge channels of each ball storage bin 1, and the control box controls the movement of each driving motor 73 to make the materials in each ball storage bin 1 fall into its corresponding ball mill 4.
[0017] Preferably, a gravity sensor type belt scale 6 is installed on the upper surface of the belt conveyor 2. The belt scale 6 is arranged between the ball storage bin group 1 and the plough-type tripper 7 closest to the ball storage bin group. The belt scale 6 is communicatively connected to the control box.
[0018] Preferably, the sector gate 5 is installed at the discharge port of its corresponding ball storage bin 1 through a rotating shaft. A hydraulic rod 8 is provided between the ball storage bin 1 and its corresponding sector gate 5. The hydraulic rod 8 is communicatively connected to the control box.
[0019] Preferably, at the upstream end of the scraper 72 along the conveying direction of the belt conveyor 2, it is at the rear side of the belt conveyor 2. A baffle is provided at the rear side of the belt conveyor 2 to prevent the materials from falling due to the accumulation of materials moving away from the discharge funnel 3.
[0020] Preferably, the control box is provided with a display screen, a signal control module, and low-voltage electrical appliances.
[0021] In this embodiment, taking the feeding of two ball mills, namely the first ball mill and the second ball mill, as an example, correspondingly, there are two storage ball bins 1 and two plough-type dischargers 7. The first storage ball bin stores the grinding materials required by the first ball mill, and the discharge funnel corresponding to the scraper of the first plough-type discharger is connected to the first ball mill. The second storage ball bin stores the grinding materials required by the second ball mill, and the discharge funnel corresponding to the scraper of the second plough-type discharger is connected to the second ball mill. When it is necessary to add grinding materials to the first ball mill, the control box controls the hydraulic cylinder on the first storage ball bin to change the stroke length of the corresponding sector gate, thereby adjusting the amount of balls fed. After the ball feeding is completed, the sector gate closes, and the grinding materials fall onto the running belt conveyor. Then, the belt scale 6 measures the weight of this feeding. The belt scale 6 feeds back the weight signal of the released grinding materials this time to the control box for measurement and statistics. The control box controls the driving motor of the first plough-type discharger to work, so that the scraper flips from above the main shaft to below and fits with the surface of the belt conveyor, realizing blocking the grinding materials and making them fall into the discharge funnel corresponding to the first ball mill. After the ball adding process is completed, the control box controls the first plough-type discharger to work to make the scraper return above the main shaft. When it is necessary to add balls to the second ball mill, the control box controls the sector gate of the second storage ball bin and the second plough-type discharger to complete the addition of grinding materials to the second ball mill. When adding grinding materials to multiple ball mills, the above process can be analogously repeated, and continuous ball feeding to multiple ball mills can be achieved.
[0022] It can realize the function of adding grinding balls to multiple ball mills, achieve uniform, continuous and on-demand addition during the ball adding process of multiple ball mills, and save space at the same time.
