Abstract
The invention discloses a high-efficiency processing system of medium-low viscosity printing ink. The system comprises a reaction kettle, wherein the bottom of the reaction kettle is connected to a mass flow circulation sand mill through a printing ink circulation pipe and a circulation pump; the other end of the printing ink circulation pipe is located in a feeding hole at the upper part of the reaction kettle; a high-speed stirring device and a basket sand mill are arranged outside the reaction kettle to stir the printing ink successively; and the reaction kettle is further connected with a reaction kettle cooling water circulation device. The capacity of the mass flow circulation sand mill is 3-4 times more than that of a pass type sand mill. The printing ink passing through the mass flow circulation sand mill returns the reaction kettle and quickly mixed well with the printing ink in the reaction kettle to make the printing ink uniform. The system can effectively shorten sanding time for the printing ink, increases wetting time of the printing ink when sanded, reduces losses during the sanding process, is compact in technological structure, reduces cleaning procedures, improves sanding effect of half-finished products, and greatly reduces manpower and material resources for the enterprise.
