One side of the top of the conveyor frame 1001 is fixedly connected to the bottom end of the first support seat 1003, and the other side of the top of the conveyor frame 1001 is fixedly connected to the bottom end of the second support seat 1009.

[0027] The screw conveyor 4 includes a conveyor casing 41 and a conveying screw 43. One side of the inner wall of the conveyor casing 41 is rotatably connected to one end of the conveying screw 43. A motor base 44 is fixedly installed at the bottom end of the conveyor casing 41. A reduction stepper motor 45 is fixedly installed on one side of the motor base 44. The output end of the reduction stepper motor 45 passes through the conveyor casing 41 and is fixedly connected to the end opposite to the conveying screw 43. The top end of the conveyor casing 41 is fixedly connected to a feed pipe 46, and the bottom end of the conveyor casing 41 is fixedly connected to a discharge pipe 42. The reduction stepper motor 45 is started after being energized, and the reduction stepper motor 45 drives the conveying screw 43 to rotate. The conveying screw 43 conveys the product injected through the feed pipe 46, and finally is discharged through the discharge pipe 42 and conveyed to the vertical mill 5.

[0028] One end of the discharge pipe 42 away from the conveyor housing 41 is fixedly connected to the side facing the vertical mill 5 , and one end of the feed pipe 46 away from the conveyor housing 41 is fixedly connected to the end facing the three-way connector 3 .

[0029] The first prompt machine 8, the second elevator 11 and the third elevator 14 all include a lifting cylinder 83 and a feed hopper 86. The bottom end of one side of the lifting cylinder 83 is fixedly connected to the bottom end of the feed hopper 86, and a discharge port 81 is provided at the top of the other side of the lifting cylinder 83. The internal transmission of the lifting cylinder 83 is connected to a bucket chain 84, and a maintenance port 85 is provided on the surface of the lifting cylinder 83.

[0030] A head component 82 is fixedly mounted on the top end of the lifting cylinder 83 , and a tail component 87 is fixedly mounted on the bottom end of the lifting cylinder 83 .

[0031] During the actual use of the embodiments of the present application, the entire ultrafine mineral powder production process system is like a large-scale mechanical orchestra with precise coordination, in which each component performs its own function and cooperates closely to methodically complete a series of complex processes from raw material input to multi-product output.

[0032] The raw materials in the batching warehouse have specific physical properties, that is, the moisture content is less than 10% and the particle size is less than 10 mm. These raw materials are firstly transported by the first belt conveyor 1.

[0033] The first belt conveyor 1 and the second belt conveyor 6 similar thereto are both equipped with a complete and reasonable structural composition. Taking the first belt conveyor 1 as an example, it includes key components such as a conveyor frame 1001, a first support seat 1003 and a second support seat 1009. The conveyor frame 1001 serves as the skeleton of the entire conveyor and provides a stable support for other components. One side of its top is firmly fixedly connected to the bottom end of the first support seat 1003, and the other side is closely connected to the bottom end of the second support seat 1009. Inside the first support seat 1003, a driven belt roller 1005 is rotatably connected, and inside the second support seat 1009, a driving belt roller 1007 is rotatably connected. The two belt rollers are connected in transmission through a belt body 1006.

[0034] In order to drive the belt to rotate and thus realize the conveying of raw materials, a servo motor 1008 is fixedly installed on the surface of the second support seat 1009. When the servo motor 1008 is powered on and started, it starts to drive the active belt roller 1007 to rotate. The rotation of the active belt roller 1007 is driven by the transmission of the belt body 1006, thereby driving the driven belt roller 1005 to rotate synchronously. During the transmission process of the belt body 1006, the raw materials placed on it are smoothly conveyed forward.

[0035] An iron remover 2 is fixedly installed on the surface of the first belt conveyor 1 and the second belt conveyor 6. This design is to remove ferromagnetic impurities that may be mixed in the raw materials. In the process of mining, transportation or storage of raw materials, some impurities such as iron filings are inevitably mixed in. If these impurities are not removed and enter the subsequent production equipment, they may cause adverse effects such as wear and damage to the equipment, and even affect the quality of the product. The iron remover 2 can accurately absorb and remove these ferromagnetic impurities through its own unique working principle, ensuring that the raw materials entering the subsequent process are of higher purity.

[0036] In addition, a cleaning seat 1010 is fixedly installed in the middle of the top of the conveyor frame 1001, and a cleaning brush 1004 is fixedly installed on the top of the cleaning seat 1010, which is in contact with the belt body 1006. During the long-term operation of the belt conveyor, some raw material particles, dust and other debris may be attached to the surface of the belt body 1006. If these debris accumulate too much, it will not only affect the transmission efficiency of the belt, but also may cause problems such as uneven raw material transportation. The existence of the cleaning brush 1004 is to regularly clean the belt body 1006, keep its surface clean, and ensure that the belt conveyor can operate continuously and stably.

[0037] After the raw materials are initially conveyed on the first belt conveyor 1, they are diverted through the three-way connector 3. One side of the three-way connector 3 is fixedly connected to the first belt conveyor 1, and the other side is fixedly connected to the screw conveyor 4. Through the ingenious design of the three-way connector 3, the raw materials can smoothly enter the screw conveyor 4 along the predetermined path.

[0038] The screw conveyor 4 is mainly responsible for further conveying the raw materials after being diverted by the three-way connector 3 to the vertical mill 5. The screw conveyor 4 is composed of main components such as a conveyor housing 41 and a conveying screw 43. One side of the inner wall of the conveyor housing 41 is rotatably connected to one end of the conveying screw 43, and a motor base 44 is fixedly installed at the bottom end of the conveyor housing 41, and a stepping motor 45 with a reduction gear is fixedly installed on one side of the motor base 44. When the stepping motor 45 with a reduction gear is powered on and started, it will drive the conveying screw 43 to rotate.

[0039] The top of the conveyor housing 41 is fixedly connected with a feed pipe 46, and the bottom is fixedly connected with a discharge pipe 42. The raw material is injected into the screw conveyor 4 through the feed pipe 46. As the conveying screw 43 rotates, the raw material is gradually pushed and discharged through the discharge pipe 42, and finally accurately transported to the vertical mill 5 to prepare for the subsequent grinding process.

[0040] The air inlet of the vertical mill 5 is connected to the hot air furnace 7. As a key device for providing a heat source, the hot air furnace 7 can generate high-temperature hot air. After the raw material enters the vertical mill 5, it will be dried by the hot air from the hot air furnace 7 in the process of falling to the grinding disc. The hot air generated by the hot air furnace 7 continuously enters the interior of the vertical mill 5 through the air inlet, so that the moisture in the raw material gradually evaporates under the action of the hot air. Since the raw material itself contains less than 10% moisture, the hot air at a suitable temperature provided by the hot air furnace 7 can ensure that the raw material reaches a suitable degree of dryness before entering the grinding process, which plays a vital role in the smooth progress of subsequent grinding operations and the guarantee of product quality.

[0041] Important grinding operations are also being carried out inside the vertical mill 5. After the raw materials are dried, they are ground on the grinding disc. The grinding components inside the vertical mill 5 cooperate with each other to apply sufficient pressure and friction to the raw materials, so that the raw material particles are gradually crushed and refined. In this process, particles of different particle sizes begin to differentiate. The fine particles will be brought to the dynamic powder concentrator for powder selection under the action of wind power, while the coarse particles will enter the vertical mill 5 again for grinding due to their own gravity and other factors. This cyclic grinding mechanism ensures that all raw materials can be fully ground, maximizes the utilization rate of raw materials, and also ensures the uniformity of the quality of the final product.

[0042] Regarding the powder selection operation, the vertical mill 5 is provided with a corresponding powder selection mechanism inside, which can select the ground particles according to the particle size, density and other characteristics. The selected semi-finished particles will enter the cyclone 9 for subsequent processing.

[0043] The cyclone 9 is an important component of the primary dust collection system in the entire process system. It is connected to the first air conveying chute 10 and the second elevator 11 in sequence. The cyclone 9 itself has a specific dust collection performance, and its dust concentration is about 400g / m 3 The dust collection efficiency is above 90%, which means it can efficiently capture and collect mineral powder particles in the air. When the semi-finished particles selected from the vertical mill 5 enter the cyclone 9, the mineral powder particles will be separated and collected according to their physical properties under the special airflow structure inside the cyclone 9. The mineral powder fineness collected by the cyclone 9 is 400m 2 / kg or more, the collected mineral powder will be smoothly transported to the finished product warehouse through the first air conveying chute 10 and the second elevator 11, and become part of the final product.

[0044] At the same time, a part of the finer particle size mineral powder will enter the dust collector 12 for secondary dust collection. The dust collector 12, the second air conveying chute 13, and the third elevator 14 are connected in sequence to form a secondary collection system. The dust collector 12 also has excellent dust collection capacity. The mineral powder fineness it collects is 600m 2 / kg or more. When the finer particle size mineral powder enters the dust collector 12, the mineral powder particles can be accurately collected by the professional dust collection mechanism inside the dust collector 12. The collected mineral powder is then transported to the second finished product warehouse through the second air conveying chute 13 and the third elevator 14 to become another finished product.

[0045] The air outlet of the vertical mill 5 is connected to the cyclone 9, which realizes the conveying and dust collection of the mineral powder. The mineral powder blown out from the air outlet of the vertical mill 5 enters the cyclone 9 under the push of the wind, which completes the conveying process of the mineral powder from the vertical mill 5 to the cyclone 9 on the one hand, and also uses the dust collection function of the cyclone 9 to preliminarily collect and purify the mineral powder on the other hand. The fineness of the mineral powder at the air outlet of the vertical mill 5 is 500-550m 2 / kg, and this fineness range also provides the basic conditions for subsequent dust collection and finished product collection in the cyclone 9 and the dust collector 12.

[0046] In addition, the air inlet temperature of the vertical mill 5 is between 200-300°C, and this temperature range has been carefully designed and debugged. The appropriate air inlet temperature can ensure that the hot air provided by the hot air furnace 7 can effectively dry the raw materials without causing adverse effects on the raw materials or equipment due to excessive temperature. The air outlet temperature is between 90-105°C. This temperature change also reflects the utilization and consumption of hot air in the drying, grinding and other operations performed inside the vertical mill 5, and also provides a suitable temperature environment for the normal operation of subsequent connected cyclone 9 and other equipment.

[0047] In the whole production process, the various equipments work together. For example, the first elevator 8 plays a role in connecting different equipments and realizing material circulation in the whole process system. After the coarse particles are discharged from the slag discharge port of the vertical mill 5, they are transported to the first elevator 8 by the second belt conveyor 6. The first elevator 8 then lifts these coarse particles to a suitable height so that they can be sent back to the vertical mill 5 for grinding by the screw conveyor 4. Similarly, the second elevator 11 and the third elevator 14 also play an important conveying role in the primary dust collection system and the secondary collection system respectively, ensuring that the collected mineral powder can be smoothly transported to the corresponding finished product bin.

[0048] In summary, the ultrafine mineral powder production process system for preparing multiple products involved in the embodiment of the present application realizes a complete process flow from raw material input to multiple product output through the careful design and close cooperation of various components. In this process, not only the drying, grinding, powder selection of raw materials, dust collection of mineral powder, and collection of finished products are effectively completed, but also the utilization rate of raw materials is improved through the circulation grinding mechanism, the quality uniformity of the product is ensured, and a reliable process guarantee is provided for the efficient production of ultrafine mineral powder.
