In the case of mixtures, sand mills can be used to run a mixture of components through for processing into a uniform paste or powder. This is widely applied in the production of paints, where pigments need to be ground with stabilizers and other components before being blended with a base. As the ingredients pass through the sand mill, they become thoroughly mixed. The very fine grind offered by this device allows for highly stable mixes without patches and chunks of various materials.
Companies with need for a sand mill may be able to rent or lease equipment for their needs, offering an opportunity to test different kinds of equipment before making a decision to purchase. It is also sometimes possible to buy used and refurbished equipment from a manufacturer or third party. Brand new sand mills can be very expensive. Grinding media are available from sand mill manufacturers, as well as other suppliers. The operator must select the best medium for a given application, weighing a number of considerations, including concerns about contamination and discoloration.
