The Basket Mill is a wet mill that combines dispersion and grinding. It is a continuous batch processing system. The entire grinding process is carried out in the same container. Can achieve ultrafine grinding. Suitable for mass production, very suitable for different colors, easy to change colors and change products.
WhatsApp: +86 18203695377The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact ...

WhatsApp: +86 18203695377The role of the dispersing agents is to enhance the dispersion process and ensure a fine particle size in order to stabilize pigments in the resin solution. As explained earlier, an efficient dispersant has to perform the three main functions: pigment wetting, dispersing, and stabilizing. Dispersing agents generally differ for aqueous and solvent
WhatsApp: +86 18203695377To achieve an optimal dispersion process, first, the pigments that are the most difficult to wet should be added and dispersed, so that they are subjected to the wetting action of liquid elements for the longest time possible, and under the most favourable conditions.
WhatsApp: +86 18203695377Step 2: Charging the media mill. As the raw feed in the liquid slurry circulates through the mill, solid particles suspended in the liquid collide with one another as well as with the milling media. The impact and shear forces result in particle size reduction. Milling media type and size are selected based on material characteristics of the ...

The mill components "attack" the particles using various mechanical forces: media, pegs, and screens, to achieve the particle breakdown.
WhatsApp: +86 18203695377The first step in making paint involves mixing the pigment with resin, solvents, and additives to form a paste. If the paint is to be for industrial use, it usually is then routed into a sand mill, a large cylinder that agitates tiny particles of sand or silica to grind the pigment particles, making them smaller and dispersing them throughout the mixture.

WhatsApp: +86 18203695377In the industry, the fineness of grind is generally achieved with a 2step process. First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.
