Description

Technical Field

[0001] The utility model relates to the technical field of vanadium-titanium magnetite screening, in particular to a ball mill coarse slag transfer system. Background Art

[0002] The ore type in the Panxi region is vanadium-titanium magnetite. The main production process involves crushing large ore into smaller particles, which are then fed to the ball mill for further processing. During the production process, the ore enters the mill through the feed port. The steel balls within the mill interact with the ore, further reducing its particle size. The ore is then discharged from the mill through the discharge port. Due to the uneven grinding effect on the ore within the ball mill, some coarse particles are present in the ore exiting the mill. If this ore were to enter the next process, it would damage the equipment. Initially, the coarse ore would fall to the ground after screening and then be manually bagged and transported. This was not only inefficient but also had adverse effects on environmental hygiene. Utility Model Content

[0017] Figure 1 This is a system flow chart of the present utility model. DETAILED DESCRIPTION

[0018] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0019] Please refer to Figure 1 This utility model provides a ball mill coarse slag transfer system. This system primarily consists of the following key components: a hopper, a ball mill, a screening assembly, a conveying assembly, a diversion system, a filter, and a control system. These components, through carefully designed connections and automated control technology, achieve refined processing and recycling of the coarse slag material.

[0020] hopper

[0021] The hopper, the starting point of the entire system, takes full account of material feeding efficiency and stability. It features a conical structure with an adjustable outlet valve at the bottom to control material flow. The hopper is constructed of wear- and corrosion-resistant alloy steel to withstand the impact and abrasion of coarse slag materials. Furthermore, a dust removal device is installed on top of the hopper to reduce dust pollution generated during the material feeding process.

[0022] In practice, the hopper is fixed on a stable support and connected to the inlet of the ball mill via a pipe. The pipe ensures that the material can slide smoothly into the ball mill and prevents the material from being blocked or scattered during the transfer process.

[0023] ball mill

[0024] The ball mill is the primary equipment in the system for crushing and grinding coarse slag. It contains a large number of grinding media (such as steel balls). The centrifugal force and friction generated by rotation crush the material and grind it to the desired particle size. The selection of a ball mill should be based on the properties of the material, the required output, and the grinding effect.

[0025] In this embodiment, the ball mill utilizes a dual-chamber structure, with the first chamber for coarse crushing and the second for fine grinding. A partition plate is installed between the two chambers to separate materials of different particle sizes. The ball mill's drive unit utilizes a variable-frequency motor, allowing for adjustable speed and power based on production needs. Furthermore, the ball mill is equipped with cooling and lubrication systems to ensure long-term, stable operation.

[0026] The ball mill outlet is connected to the screening assembly inlet via a sealed pipe. The pipe design must consider material flowability and prevent clogging. Furthermore, the inner wall of the pipe must be treated with a wear-resistant finish to extend its service life.

[0027] Filter components

[0028] The screening component is the key link in the system to achieve fine material processing. It includes multiple sub-components such as the grinding head screen, magnetic separator and vibrating screen.

[0029] Grinding Screen: Located at the front end of the screening assembly, the grinding screen is used to initially separate larger particles. The mesh size of the grinding screen is determined based on the material characteristics and production requirements. The mesh is made of wear-resistant and corrosion-resistant stainless steel. The grinding screen uses a vibration source such as an exciter or eccentric block, which causes the material to move across the screen, achieving a screening effect.

[0030] Magnetic Separator: Located after the grinding head screen, the magnetic separator is used to remove metallic impurities from the material. The magnetic field strength of the magnetic separator can be adjusted according to the content and nature of the metallic impurities in the material. The magnetic separator must be designed to ensure that the material passes evenly through the magnetic field and effectively adsorbs and separates metallic impurities.

[0031] Vibrating screen: The vibrating screen is the final step in the screening process, used for more detailed material screening. It utilizes a multi-layered screen structure, each with a different aperture to separate materials of varying particle sizes. The vibrating screen also uses a vibrator or eccentric block as its vibration source. High-frequency vibrations create rapid movement of material across the screen, resulting in efficient screening.

[0032] The subassemblies of the screening system are connected by pipes or conveyor belts. During these connections, smooth material transfer and blockage prevention must be ensured. Furthermore, appropriate collection devices must be installed at the outlets of each subassembly to collect the screened material and send it to subsequent processing stages.

[0033] Conveying components

[0034] The conveying component uses an enclosed conveyor belt as the main transmission equipment. The enclosed conveyor belt design effectively prevents dust and scattering of materials during the conveying process, thereby improving the working environment and reducing dust pollution.

[0035] The closed conveyor belt is made of high-strength, wear-resistant, and corrosion-resistant synthetic rubber. Multiple support rollers and drive pulleys are installed within the belt to ensure stable operation and smooth material transfer. The conveyor belt drive utilizes a variable-frequency motor and reducer, allowing for adjustable conveying speed and power according to production needs.

[0036] The conveyor belt's inlet is connected to the screen assembly's outlet (specifically, the final outlet of the vibrating screen). During the connection process, ensure that the conveyor belt's width, height, and speed match the screen assembly's outlet parameters. Also, ensure that appropriate guides and buffers are installed at the conveyor belt's inlet to prevent material from impacting and scattering as it enters the conveyor belt.

[0037] The conveyor belt's outlet is connected to the diversion system's inlet. During the connection process, ensure that the conveyor belt's end maintains a certain distance and angle from the diversion system's inlet to ensure smooth material flow. Appropriate baffles or guides should also be installed at the conveyor belt's outlet to prevent material from shifting or spilling during transport.

[0038] 5. Diversion system

[0039] The diversion system is an important part of the entire transfer system. It is responsible for distributing the screened and transported materials to different processing paths according to predetermined requirements. In this embodiment, the diversion system adopts a design scheme combining multi-branch pipelines and intelligent control valves.

[0040] Multi-branch piping: The diversion system is equipped with multiple branch pipes, each corresponding to a specific processing path. These pipes are made of wear-resistant and corrosion-resistant alloy steel to ensure long-term stable operation. The pipes are connected through connectors such as tees and crosses to form a complex network structure to meet the diversion needs of different materials.

[0041] Intelligent control valves: Intelligent control valves are installed at the entrance of each branch pipeline. These valves are remotely controlled by a control system and can automatically adjust their opening or switch paths based on parameters such as material properties, production requirements, and processing technology. The design of intelligent control valves must ensure rapid response, precise control, and include fault self-diagnosis and alarm functions.

[0042] During implementation, a diversion plan is first determined based on the material's properties and processing requirements. Then, corresponding control parameters and logic rules are set in the control system. When material enters the diversion system via a conveyor belt, the control system automatically determines the material's destination based on pre-set parameters and rules, and controls the corresponding intelligent control valves to adjust their openings or switch paths. This ensures that the material is accurately distributed to the designated processing path.

[0043] 6. Filter

[0044] During the coarse slag grinding process, a hydraulic classification system (not shown) is used for cleaning. Therefore, a filter is used in the final process to further process or discharge the material in the system. In this embodiment, the filter is a filter press or vacuum filter, and the specific filter type depends on the nature of the material and the processing requirements.

[0045] Filter press: A filter press separates liquids from solids in a material by applying pressure. The material is placed on a filter cloth, and then pressure is applied to force the liquid out through the cloth, while the solids remain on the cloth, forming a filter cake. Filter presses offer advantages such as high throughput and excellent filtration efficiency, making them suitable for processing materials with high solids content.

[0046] Vacuum Filters: Vacuum filters use vacuum suction to separate liquids from solids in materials. They operate by creating a vacuum inside the filter chamber, then drawing the liquid through the filter cloth for discharge. Vacuum filters offer advantages such as ease of operation and high filtration efficiency, making them suitable for processing materials with low solids content.

[0047] In practice, the appropriate filter type is selected based on the material's properties and processing requirements, and installed at the appropriate location in the diversion system. The material to be filtered is then piped from the diversion system into the filter for processing. The treated material can then be further utilized or discharged as needed.

[0048] 7. Control system

[0049] The control system is the core of the entire transport system, responsible for automated control and intelligent management of the entire system. In this embodiment, the control system uses a PLC (Programmable Logic Controller) as the main control unit, combined with touch screens, sensors, actuators and other devices to achieve automated control and intelligent management of the system.

[0050] PLC master control unit: As the core component of the control system, the PLC is responsible for receiving signals from various sensors and actuators, processing and judging the data according to preset control programs and logic rules. The PLC then issues corresponding control instructions to actuators (such as motors and valves) to achieve automated control of the entire system.

[0051] Touch screen: The touch screen serves as a human-machine interface, displaying information such as the system's operating status, parameter settings, and fault alarms. Operators can use the touch screen to monitor and operate the system, such as modifying control parameters and starting / stopping equipment.

[0052] Sensors and actuators: Sensors monitor the system's operating status and material parameters (such as flow, pressure, and temperature) in real time and transmit this information to the PLC master control unit. Actuators receive control commands from the PLC and drive corresponding devices (such as motors and valves) to perform actions.

[0053] During implementation, the appropriate PLC model and touchscreen specifications are selected based on the system's control requirements. Next, the appropriate control program and logic rules are written into the PLC to achieve automated control and intelligent management. Next, sensors and actuators are installed at key locations throughout the system and connected to the PLC main control unit and touchscreen via cables or wirelessly. Finally, the entire control system is debugged and tested to ensure it functions properly and meets production requirements.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
