The Blendcon® air blender by Dynamic Air Inc. is one of the fastest, most efficient blenders available for mixing large batches of dry bulk materials, according to the manufacturer. It can typically blend a 300 cubic foot batch in just four minutes and can handle batches up to 200 tons in capacity. By producing large, consistent, homogeneous batches, the Blendcon air blender simplifies material handling and quality control, and increases productivity. The Blendcon air blender uses compressed air to lift, turn and tumble dry materials, utilizing the high kinetic energy released when compressed air is allowed to expand rapidly to atmospheric pressure. Compressed air is pulsed into the material in an upward circular pattern. This blending method is so effective that very few pulses are required to complete the blending cycle. Blending is fast and thorough. The ratio of horsepower to material blended is very low, resulting in high efficiency. The discharge cone valve helps to eliminate dead spots during blending and substantially reduces segregation during discharge. There are no mixer arms or blades to wear out or clog, making the Blendcon air blender ideal for blending abrasive materials which would shorten the life of a conventional blender.
