The latest product is a mobile mixing device of our own design. It consists of three bigger hoppers for individual components and of two smaller hoppers for microcomponents. The components are dosed on a belt conveyer by which they are conveyed into a continuous drum mixer and from there they can be conveyed (using another belt conveyer) directly to a truck provided. The device has been developed and manufactured to mix earth for golf courses. The whole device including its own power supply unit is placed on a standard trailer and can be used in any place.
