WLDH series double helical horizontal ribbon mixer is widely used to mix powder, granule, and small liquid additives to achieve paste product in food, chemical, and construction line. It is particularly good at handling sticky wet paste products.
WLDH series double helical horizontal ribbon mixer consists of a U-shaped horizontal trough and a specially fabricated ribbon agitator. A ribbon agitator consists of a set of inner and outer helical blades. The outer ribbon moves materials toward the center of the trough, and the inner ribbon moves the materials toward the outside of the trough. The ribbon also rotates at approx. 300 fpm, thus moving materials both radially and laterally to insure thorough blends in short cycle times. Ribbon agitators are used for blends that will be between 40 and 100% of the rated capacity of the blender.
1. Strong and fast mixing: Strong and fast mixing can be achieved due to effective drive design and variable speed blending.
2. High-degree of homogeneity: When material is added at the rate of 0.1%, the homogeneity can reach 98% in short time.
3. Heating jacket: A heating jacket can be equipped as an option in the mixing tank shell for heating or drying process. The heating medium can be steam, hot water or hot oil. Design pressure is 0.3 Mpa.
4. Liquid spray nozzle: Spray nozzles can be equipped as an option to add liquid additives which can be evenly sprayed onto the mixture.
5. Well bearing sealing: shaft sealing is the combination of Teflon packing sealing and air-tight sealing to make sure long life-span.
6. Automatic discharging valve: The combined discharge valve is pneumatic planer flap valve. The flap plate can perfectly match the mixing tank inner wall to make sure no dead corner.
