Magaldi heavy-duty mixers are designed for controlled, efficient, and dust-free conditioning of dusty, abrasive materials (ash from different processes, sand, metal oxides, minerals, cement, high-calcium oxide content, etc.) in several industries, including coal-fired power plants, Waste-to-Energy plants, cement factories, foundries, and mines. The Magaldi Paddle Mixer is a fully enclosed twin-shaft humidifier designed to treat ash or other dusty, abrasive material with water and discharge up to 400 m3/h of moist, conditioned material to open trucks, rail cars, or downstream equipment. The Mixer features an array of wear-resistant pitched paddles on twin, contra-rotating shafts. The paddles are connected to the shafts in such a way as to be very tough. The action of the paddles, which create a kneading and folding over motion inside the mixing chamber, pushes material forward while contra-rotating shafts lift it to create an intimate mixture with water. Within the chamber, high-pressure nozzles installed above the mixing paddles spray the powder with a precisely regulated water curtain. The water flow rate is controlled through suitable valves and adjusted according to the features of the material to condition.
