A basket mill for batch grinding with hydraulic lift, infinitely variable speed and cooled basket. * the combination of dissolving impeller and grinding disc provides outstanding dispersing and grinding results within a short time and with less power consumption. * this combination creates expulsion and suction flows ensuring that all the base product passes through the grinding chamber many times during the operation and is progressively and uniformly processed. * since no pumps, hoses, pipes, valves and additional containers are necessary, the cleaning is very easy and a quick change of the millbase is possible. The products can be manufactured from start to finish using the same container. * the basket is cooled inside. Thanks to double walled basket together with the easily interchanable jacketed container for effective and efficient water cooling to assist in controlling batch temperature * infinitely variable speed control with updated frequency converters. Variable speed range from 0 to 1200 rpm with nearly constant torque. * processing is done in a closed container without evaporation of solvents and with practically no product loss. The contamination of the enviroment is prevented * the basket is designed as an open system so that grinding beads remains in a floating state. No grinding beads escape during the operation. Replacement of worn beads can be carried out within a short time. * total process control with safety and monitoring system. * simple handling.
