Abstract
Description
Technical Field
[0001] The utility model relates to the field of tailings cement production, and more specifically, to a processing device for tailings type cement admixture. Background Art
[0002] Tailings-based cement admixtures are functional materials made primarily from various metal or non-metallic mine tailings. After undergoing certain processing steps, they are used in cement production to improve cement performance and reduce production costs. These tailings are typically waste generated during ore mining and beneficiation processes and contain a variety of mineral components. Common tailings-based cement admixtures on the market include iron tailings admixtures, copper tailings admixtures, and lead-zinc tailings admixtures.
[0003] The production process of tailings-based cement admixtures mainly involves screening, grinding, and mixing. Tailings of different particle sizes may have different effects in cement. Finer tailings particles (such as those less than 75μm) tend to have higher activity and can better participate in the hydration reaction of cement; while slightly coarser particles (such as 75-300μm) can play a role in filling, etc. Therefore, the size of the tailings particles determines the quality of the admixture. Therefore, grinding is an important processing step for the admixture. In the existing technology, ball mills are mostly used to grind tailings particles. Through the rotation of the cylinder, the steel balls or other grinding media in the cylinder impact the ore. In the existing technology, a feed port is opened on the curved side of the drum to facilitate loading and unloading. When the grinding is completed, the door is opened and the ore powder and steel balls inside are poured out together. The falling steel balls will cause damage to the conveyor belt below. At the same time, the existing ball mills cannot screen the ore particles, and thus cannot accurately control the grinding quality. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0022] Example:
[0023] See also Figure 1-Figure 3As shown, a processing device for tailings type cement admixture includes a bracket 1 placed on the ground, the bracket 1 is a concave structure as a whole, and a bearing seat 3 is symmetrically arranged on the top of the bracket 1. A roller 6 is rotatably installed between the two bearing seats 3, and the roller 6 is arranged horizontally. A plurality of reinforcing ribs 7 are evenly arranged on the surface of both sides of the roller 6 to improve the strength of the roller 6. A driving mechanism 2 is provided on one side of the bracket 1, and the output end of the driving mechanism 2 is connected to one end of the roller 6, and then the roller 6 is driven to rotate by the driving mechanism 2. A discharge port 8 is provided on one side of the curved surface of the roller 6, and the discharge port 8 is provided on the side of the roller 6 away from the driving mechanism 2. The discharge port 8 area protrudes outward to increase the thickness of the roller 6 in this area, and a sealing arc plate 9 for sealing the discharge port 8 is installed on the inner side of the discharge port 8 sliding along the surface of the roller 6. The sealing arc plate 9 can rotate along the axis of the roller 6 within a certain range, and then control whether it seals the discharge port 8. The outer side of the discharge port 8 is The sieve 14 is mounted on the outer side of the sealing arc plate 9 and a boss 13 is provided on one side of the curved surface of the drum 6. The outer side of the boss 13 is flush with the surface of one side of the drum 6. The boss 13 corresponds to the sealing arc plate 9. One end of the sieve 14 is fixed with a slide rod 15 by screwing to facilitate disassembly between the two. After installation, the two move synchronously. The slide rod 15 passes through the boss 13. The slide rod 15 is parallel to the axis of the drum 6. The end of the slide rod 15 away from the screen 14 is rotated to adjust the internal threaded cylinder 16. The internal threaded cylinder 16 exceeds the surface of one side of the drum 6. By rotating and adjusting the internal threaded cylinder 16, the distance between the rolling body 17 at its end protruding from the side of the drum 6 can be controlled. The surface of the end of the adjusting internal threaded cylinder 16 away from the slide rod 15 is embedded with a rolling body 17 to reduce friction.
[0024] Among them, when the drum 6 rotates, the internal threaded barrel 16 can be adjusted inward to reduce the distance that the rolling body 17 extends, thereby preventing it from being hit during rotation. Conversely, when discharging, the screen 14 is placed at the bottom. At this time, the internal threaded barrel 16 can be rotated outward to adjust so that the rolling body 17 extends outward and contacts the surface of the turntable 18.
[0025] Please refer to Figure 2 and Figure 3 As shown, a spring 19 is sleeved on the surface of the slide rod 15, one end of the spring 19 contacts the outer surface of the boss 13, and the other end of the spring 19 contacts the adjustment internal threaded cylinder 16. The elastic force of the spring 19 can ensure that the slide rod 15 always has an outward force when discharging, and then the rolling body 17 at the end always maintains contact with the surface of the turntable 18.
[0026] Please refer to Figure 1A crossbeam 4 is provided on one side of the bracket 1, a motor 5 is fixed on the surface of the crossbeam 4, a turntable 18 is installed on the output end of the motor 5, the turntable 18 is placed below the crossbeam 4, and a plurality of extrusion protrusions 181 are evenly provided on the surface of the turntable 18. The surface of the turntable 18 is at the same height as the lowest point of the curved surface of the drum 6, so that the discharge port 8 rotates to the bottom when discharging, and at this time the height of the screen 14 is close to that of the turntable 18.
[0027] Please refer to Figure 1 and Figure 2 As shown, positioning threaded holes 91 are symmetrically provided on the outer side of the surface of the sealing arc plate 9, and two ear plates 10 are provided on the surface of the drum 6. Locking bolts 11 pass through the surfaces of the two ear plates 10. The ear plates 10 are placed on one side of the discharge port 8, and the end of the locking bolt 11 is adapted to the internal size of the positioning threaded hole 91 so that it can remain stable after the sealing arc plate 9 is closed.
[0028] Working principle: First, remove the screen 14 when loading. At this time, the steel balls and ore materials can be poured into the drum 6 through the discharge port 8. The sealing arc plate 9 is closed and the discharge port 8 is sealed by the cooperation of the locking bolt 11 and the positioning threaded hole 91. At this time, the inside of the drum 6 is in a sealed state. The power of the driving mechanism 2 can drive the drum 6 to rotate. The rotation of the drum 6 can drive the internal steel balls to rub against the ore to achieve further crushing of the ore. When the grinding is completed, stop the rotation of the drum 6 and keep the discharge port 8 With the opening downward, the sealing arc plate 9 is opened to open the discharge port 8 downward. At this time, the ore powder will be discharged through the screen 14. At the same time, the extension distance of the rolling body 17 can be controlled by screwing and adjusting the internal threaded cylinder 16, so that the rolling body 17 can come into contact with the turntable 18. At this time, the starting motor 5 can drive the rotation of the turntable 18 to drive the slide rod 15 to move axially back and forth through the extrusion convex portion 181, and then drive the screen 14 to perform reciprocating vibration screening, and the qualified ore is screened out, retaining the internal steel balls and unqualified ores.
