Classification of sand grinder

Sand mill belongs to wet ultrafine grinding equipment, which is developed from ball mill. Widely used for dispersion and grinding of pigments in ink production. Saunders is classified in different ways:

According to the structural shape of the mixing shaft, it can be divided into disk type, rod type and rod disk type (that is, bump type).

According to the arrangement of grinding cylinders, it can be divided into vertical and horizontal.

According to the volume of the cylinder, it can be divided into laboratory use, small, medium, large and super large.

According to the media separation mode, it can be divided into static separation sand mill and dynamic separation sand mill.

According to energy density (installed power per unit volume), it can be divided into low/high energy density sand mills.

To produce different kinds of ink, the structure of the sand mill is also different. Generally, the following rules are observed: the production of gravure printing ink generally uses a needle (5-50 liters) or a disc sander (10- 100 liters). Rotary offset printing ink generally uses a vertical rod (5-130l) or a horizontal disc sander (60-500l), while the production of ultra-high viscosity sheet-fed ink often uses a cone sander or a three-roller machine with high energy density. Ink-jet inks (solvent-based inks and pigments) generally use high energy density needles (horizontal or vertical) and centrifugal turbine rotors (new patented products).
