Description

Technical Field

[0001] The invention relates to the technical field of ink production equipment, in particular to an ink sand mill. Background Art

[0002] At present, the common equipment for ink grinding includes three-roller ink mill, ball mill and sand mill. The principle of grinding is to rely on shear force, extrusion and friction to complete the dispersion of particles. The three-roller ink mill is used for the more viscous paste ink; the ball mill and sand mill are used for the thinner or volatile ink. Compared with the ball mill, the sand mill is more suitable for industrial production and has higher production efficiency.

[0003] The sand mill drives the sand and gravel to rotate by stirring to complete the grinding process. The advantage of using a grinder is continuous production and high efficiency. The sand mill stirs the material and the grinding medium in the cylinder together through a high-speed rotating separator. Therefore, there is a strong collision, friction and shearing effect between the solid particles in the material and the grinding medium, thereby achieving the purpose of accelerating the grinding of fine particles and dispersed aggregates. The grinding process needs to be cooled to prevent the raw materials from deteriorating due to high temperature. The existing cooling method is to absorb heat from the outside of the kettle through external heat exchange, which has low cooling efficiency, and the shutdown heat dissipation affects the production efficiency. The external heat absorption is not timely and unreliable. Now the sand mill grinds the raw materials to the required size and then discharges them to achieve the purpose of continuous production. Raw materials are continuously added during the grinding process, and the raw materials that meet the size cannot be discharged in time, which reduces the grinding efficiency. Summary of the invention

[0019] Specific usage process:

[0020] The raw material enters the first sanding chamber 7 through the feed pipe 12 for the first sanding treatment. After the raw material is sanded to the required diameter, it enters the second sanding chamber 8 for the second sanding. This process is repeated four times and the raw material is finally discharged from the discharge pipe 13. The sanding process can be continued, thus achieving the purpose of continuous production.

[0021] During the sanding process, the filter assembly 11 filters the materials of the same diameter. The diameter of the material in the next sanding chamber is smaller.
