Description

Technical Field

[0001] The invention relates to the technical field of ceramic raw materials, in particular to a granulating device for ceramic raw materials and a granulating method thereof. Background Art

[0002] In the production process of functional ceramics, from the perspective of facilitating firing and solid-phase reaction, it is hoped to obtain ultrafine raw material particles. However, the finer the powder, the larger the surface area and the worse the fluidity. It is not easy to fill the mold evenly during dry pressing. The molded parts often have problems such as voids, loose corners, layer cracks, and elastic failure. The granulation process is often used to solve this problem. The granulation process is to grind the powder, dry it, add an adhesive, and make it into particles with good fluidity and a particle size of about 0.1 mm.

[0003] Dry granulation of fine powder of ceramic raw materials is a very difficult production process. It requires that the precisely proportioned dry fine powder and the binder be fully collided and mixed in space to form small particles, and then the small particles are grown to a certain size for output, and the particles with a particle size of 0.1 mm are obtained after screening. Traditional granulation devices cannot automatically weigh ceramic raw materials and add adhesives according to the ratio. They often use manual weighing and mixing to granulate, which is inefficient and has poor effects. Manual screening is required later to ensure that the particle size of the ceramic granulation is consistent and meets the use requirements. Therefore, a granulation device and a granulation method for ceramic raw materials that improve the quality and effect of ceramic raw material granulation are very necessary.

[0030] like Figure 6 , Figure 7 The second screening assembly 7 includes an inner screen cylinder 45 and an outer screen cylinder 46, both of which are cylindrical screens with openings at both ends.

[0033] The mesh diameter of the inner screen cylinder 45 is 0.01 mm larger than the diameter of the ceramic particles required for production, so that the ceramic particles that meet the production needs are screened out of the inner screen cylinder 45 and fall into the cylinder cavity of the outer screen cylinder 46, while the ceramic particles with a diameter larger than that required for production are retained in the inner screen cylinder 45. At the same time, the mesh diameter of the outer screen cylinder 46 is 0.01 mm smaller than the diameter of the ceramic particles required for production, so that the ceramic particles smaller than the production needs are screened out of the outer screen cylinder 46 for a second time.

[0037] At the same time, the rotary motor 30 is started to drive the drum 8 to rotate, and the direction of rotation of the drum 8 is opposite to the direction of rotation of the agitator 17.

[0038] After the mixing and granulation of the ceramic raw materials is completed by the mixing assembly 4, the output end of the electric telescopic rod 27 is controlled to retract, so that the sliding plate 21 slides in the cavity 20, and the feeding port 25 on the sliding plate 21 moves and is arranged concentrically with the discharge port 11 on the support plate 9, and the mixed and stirred ceramic raw materials fall into the discharge cavity 34 of the hopper 33 through the feeding port 25; The second drive motor 39 is started, and the second drive motor 39 drives the turntable 36 and the screw conveying rod 37 to rotate, so that the ceramic raw material in the discharge chamber 34 is transported to the side of the discharge port 35, and flows out of the hopper 33 through the discharge trough 38 and falls on the screen 1 42; The oscillator is started, and the ceramic raw material on the screen 42 moves toward the second screening component 7 under the oscillation of the oscillator. During the movement, ceramic particles with a particle diameter smaller than the diameter required for production are screened out, and the screened ceramic particles are transported out by the first conveyor belt 53. The ceramic raw material passing through the first screening component 6 enters the inner screen cylinder 45 of the second screening component 7 for a second screening, and the ceramic particles with a particle diameter larger than the diameter required for production are retained in the inner screen cylinder 45. Under the action of rotation, the ceramic raw material passes through the inner transmission cylinder 55 along the spiral baffle 2 57 and falls onto the third conveyor belt 60, and is transported out through the third conveyor belt 60; The ceramic raw material passes through the inner screen cylinder 45 and enters the outer screen cylinder 46.
