[0002] Magnesite calcined at 750-1100℃ is called "light burning", and its product is called light burning magnesium powder, or simply light burning powder. Magnesite is a magnesium carbonate mineral, which is the main source of magnesium. It belongs to calcite, and the content of natural magnesite is generally low, so it needs to be processed to increase the content of magnesite.
[0003] During the production process of light-burned powder, magnesite crushing equipment is required to crush the magnesite, and then the crushed magnesite is collected.
[0004] Cone crusher can crush magnesite. One structure of existing cone crusher includes main roller and protrusion on the inner wall of outer cylinder and the position relationship of the gap between them gradually decreasing from top to bottom. Magnesite in the gap is crushed by squeezing by protrusion through the rotation of main roller.
[0005] However, there is a problem with the existing structure. When the two protrusions squeeze and crush the dolomite block, the dolomite block is easy to slip between the two protrusions due to the small contact area between the protrusions and the dolomite block and the lack of vertical limit. Especially when there is less material on the top and the downward squeezing force on the dolomite block is small, it is more likely to slip, thereby affecting the crushing efficiency. Utility Model Content

When working, the surface where the convex strips contact with the magnesite block is a concave surface, which increases the contact area with the magnesite and has a certain limit in its vertical direction, so as to avoid the magnesite from slipping during extrusion crushing and affecting the crushing efficiency.
[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a dolomite crushing device for light-burned powder production, comprising an outer cylinder, a main roller, a support leg, a motor, a cover plate, a plurality of first convex strips and a plurality of second convex strips, the outer cylinder is a conical shell shape without an upper and lower bottom, and is arranged on the support leg, the cover plate is fixedly arranged on the outer cylinder, a feed port is arranged on one side of the cover plate, the main roller is conical, and the cone angle of the main roller is smaller than the cone angle of the outer cylinder, the main roller is arranged in the outer cylinder and is coaxial with the outer cylinder, the motor is fixedly arranged at the center position of the upper surface of the cover plate, the output end of the motor passes through the cover plate and is fixedly connected to the center position of the top of the main roller, a gap gradually decreasing from top to bottom is formed between the main roller and the outer cylinder, a plurality of first convex strips are evenly arranged on the inner wall of the outer cylinder, a plurality of second convex strips are evenly arranged on the outer wall of the main roller, and the first convex strips and the second convex strips are designed to be wavy.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] like Figure 1-2 As shown, a magnesite crushing device for light-burned powder production includes an outer cylinder 3, a main roller 6, a support leg 11, a motor 8, a cover plate 7, a plurality of first convex strips 4 and a plurality of second convex strips 10. The outer cylinder 3 is a conical shell without upper and lower bottoms and is arranged on the support leg 11. The cover plate 7 is fixedly arranged on the outer cylinder 3. A feed port 9 is arranged on one side of the cover plate 7. The main roller 6 is conical, and the cone angle of the main roller 6 is smaller than the cone angle of the outer cylinder 3. The main roller 6 is arranged in the outer cylinder 3 and is coaxial with the outer cylinder 3. The motor 8 is fixedly arranged at the center position of the upper surface of the cover plate 7. The output end of the motor 8 passes through the cover plate 7 and is fixedly connected to the top center position of the main roller 6. The main roller 6 and the outer cylinder 3, a gap gradually becomes smaller from top to bottom, a plurality of first ridges 4 are evenly arranged on the inner wall of the outer cylinder 3, a plurality of second ridges 10 are evenly arranged on the outer wall of the main roller 6, the first ridges 4 and the second ridges 10 are designed to be wavy 5; the wavy 5 of the first ridges 4 and the second ridges 10 includes a concave surface 14 and a convex surface 13, the concave surface 14 of the first ridge 4 corresponds to the concave surface 14 of the second ridge 10; a fixing rod 12 is provided at the bottom of the outer cylinder 3, a rotating shaft 1 is provided at the center of the bottom of the main roller 6, and the rotating shaft 1 is rotatably connected to the fixing rod 12 through a bearing; a circle of the edge of the upper surface of the main roller 6 is designed to be an outwardly inclined inclined surface 15.
[0019] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:
[0020] According to the instruction manual Figure 1-2It can be seen that when the utility model is working, the cover plate 7 and the outer cylinder 3 are fixed without relative movement, and the personnel feed the material into the outer cylinder 3 through the feed port 9. Since the conical outer cylinder 3 and the main roller 6 are coaxial, and the cone angle of the main roller 6 is smaller than the cone angle of the outer cylinder 3, a gap gradually decreases from top to bottom between the main roller 6 and the outer cylinder 3. The magnesite block material first enters the upper gap, and the motor 8 rotates to drive the main roller 6 to rotate. Since the outer wall of the main roller 6 is evenly provided with a plurality of second convex strips 10, and the inner wall of the outer cylinder 3 is evenly provided with a plurality of first convex strips 4, the magnesite block material enters each After the two first ridges 4 and every two second ridges 10, the rotating second ridges 10 cooperate with the first ridges 4 to extrude and crush the block material, and the gradually smaller gap also achieves the effect of step-by-step crushing. The first ridge 4 does not interfere with the movement of the second ridge 10. Since the first ridge 4 and the second ridge 10 are both designed in a wavy shape 5, the surface of the first ridge 4 and the second ridge 10 in contact with the dolomite block material is a concave surface 14, which increases the contact area with the dolomite and has a certain limit in its vertical direction, thereby avoiding the slippage of the dolomite during extrusion and crushing, thereby improving the crushing efficiency.
[0021] Among them, the wavy shape 5 of the first convex strip 4 and the second convex strip 10 includes a concave surface 14 and a convex surface 13. The concave surface 14 of the first convex strip 4 corresponds to the concave surface 14 of the second convex strip 10, and the convex surface 13 corresponds to the convex surface 13. When crushing, when the concave surface 14 of the first convex strip 4 and the second concave surface 14 squeeze the dolomite block, the limiting of the dolomite block is more stable to prevent it from slipping. Even if there is a dolomite block between the convex surface 13 of the first convex strip 4 and the second convex strip 10, it will still enter the concave surface 14 after sliding a short distance and be crushed, thereby improving the crushing efficiency.
[0022] Among them, a fixed rod 12 is arranged at the bottom of the outer cylinder 3, and a rotating shaft 1 is arranged at the center position of the bottom of the main roller 6. The rotating shaft 1 is rotatably connected to the fixed rod 12 through a bearing, which is a way to ensure the stable rotation of the main roller 6. Other existing technologies can also be used.
[0023] The upper edge of the main roller 6 is designed as an outwardly inclined slope 15, so that the material can slide toward the gap between the main roller 6 and the outer cylinder 3 after loading, thereby improving the feeding efficiency.
[0024] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
