Preferably, the paddle is uniformly distributed on bearing around bearing, and paddle is in have certain curved angle Triangle.

Preferably, the sand milling tank is equipped with lapping stick, and the lapping stick is in the triangle of certain curved angle, institute It states and is additionally provided with a small triangle arc strip inside the curved angle of lapping stick.

Preferably, the curved angle of the paddle is set with the curved angle that lapping stick on tank is sanded in opposite direction It sets.

Preferably, the discharge port is additionally provided with filter screen inside the position of the top installation convex with taper.

Preferably, access hole is additionally provided on the sand milling tank, the access hole is equipped with access cover, the access hole It is sealed with tank body, sealing ring is equipped in access cover.

Compared with prior art, the utility model has the beneficial effects that

(1) the water paint pigments and fillers sand mill, gear wheel and pinion gear engaged transmission, driving device will be subtracted by shaft coupling Speed motor and motor connect, and play the effect of buffering and maintenance safety in centre, avoid power device load starting Possible damage, it is more safe and reliable to make driving, while structure is simple, when also facilitating failure when with service load variation Dismounting and maintenance.

(2) the water paint pigments and fillers sand mill is sanded the paddle inside tank and is in the lapping stick on tank body Opposite direction setting improves and tank is sanded to the shearing force of pigments and fillers, further improves the effect of grinding and dispersion.

(3) the water paint pigments and fillers sand mill, discharge port were additionally provided with inside the position of the top installation convex with taper Strainer, taper is convex so that discharging is easier, and filter screen can filter out the bulky grain of the inside, is especially added to when in sand milling tank When abrasive media, abrasive media can be stopped to come out in discharging.
