Dry Mixers (dry powder mixer, industrial mixers) 1, Scope of Application: In the U-shaped container, there are positive and negative ribbons. Special proportion of the two ribbons can be rectified with the kind of material, quantity and the proportion of body. This mixer has good effect on mixing viscosity or cohesion powder. 2, Characteristic: A, Fast mixing speed can satisfy the rigorous demand of mixing the materials with different physical property. B, The rotation is under critical speed, which will reduce the effect of fragmentation to the material(e.g. Crystal particle) C, Lower height of the container is convenient for installation. D, The positive and negative ribbons are set up at he same level, forming a mixing environment of low power but high efficiency. 3, Working Principle: A, The horizontal axes make the materials move up and down. B, The outer ribbon gathering the material from sides to center and the inner ribbon pushing the material from center to sides. C, Every screw makes the materials do axial and radial movement, the materials do relative cyclical movement so to gain the intensive mixings ends. 4, Specification: (See the Table) 5, Seal: The mixing result and the clean after-mixing environment depend on the sealing property. Our company provides various sealing devices according to difference of materials. The normal sealing structure is stuff seal and also called TEFLON seal. After using for a period, user(s) should fasten and enhance it. However, the dynamic seal has a long-time sealing effect and is especially fit for the powder, liquid 6, feeding inlet on the body cover: Two types: A, used in the whole mixing/ blending process: In order to connect the feeding device, we design the connecting mouth B, used in the manual feeding: In order to operate and clean inside of the body, we design feeding inlet(s) or door(s). 7, Discharging: There is a discharging valve at the bottom of mixer body. When mixing different types of materials, we use flat discharging valve. The operation of the discharging valve should be convenient and there are three types: Manual, air driven and electricity driven. The manual discharging is operated on the valve and the open extent is controlled by hand freely. The air driven discharging valve, assembled with cylinder, work under the air pressure. The electricity driven discharging valve works under control of electricity control box. 8, temperature control: We can use a jacket when heating, cooling or heat-preservation is needed. The jacket is filled by circulation and heat conduction medium and can not bear high pressure. There are two kinds of heat conduction medium: Water and oil. The water temperature should be limited in 90 and the oil temperature should be limited in 300. The jacket coordinates the external heating system, the expulsion system, the pipeline to carry on to the material continues and even temperature processing.
