Working principle and structure of ribbon mixer

Working principle and structure of ribbon mixer

Ribbon blender is widely used in putty paste, real stone paint, dry powder, putty, medicine, food, chemicals, feed, ceramics, refractory materials, etc.

The working principle of the ribbon mixer: the materials of various components are calculated into the mixer according to the formula ratio, and the materials are mixed under the push of the ribbon spiral blades. The outer ribbon pushes the material from one end to the other, and the inner ribbon moves the material in the opposite direction. The inner layer is pushed to one side and then rolled inside and out, and the outer material is pushed to the other side. Rolling outwards. During the convection process, the two materials flow into each other, become mixed and mixed, and then mix again during the tumbling process on both sides. This is repeated several times, and finally the boring from the unloading door is discharged through the discharge control mechanism. Out.

Structural features: It consists of U-shaped container, ribbon stirring blade and transmission parts; U-shaped long body cylinder structure ensures small resistance movement of mixed material (powder, semi-fluid) in the cylinder. The positive and negative rotating screws are mounted on the same horizontal axis to form a low-dynamic and high-efficiency mixed environment. The ribbon-shaped blades are generally made of two or three layers, and the outer spiral gathers the materials from both sides to the center, and the inner spiral will The material is transported from the center to the sides, allowing the material to form more eddy currents in the flow. Speed ​​up the mixing speed and improve the mixing uniformity;

Discharging method: The powder material adopts the pneumatic large opening door structure, which has the advantages of quick discharge and no residual; the high-fine material or semi-fluid material adopts manual butterfly valve or pneumatic butterfly valve, the manual butterfly valve is economical, and the pneumatic butterfly valve is semi-fluid The sealing is good, but the cost is higher than the manual butterfly valve. The jacket can be configured where heating or cooling is required. The heating method has two modes: electric heating and heat conduction oil heating: electric heating is convenient, but the heating rate is slow, and the energy consumption is high; the heat conducting oil heating needs to be equipped with oil pan and oil guiding power, pipeline, and the investment is large, but the heating speed is fast. , low energy consumption. The cooling process can directly inject cooling water into the jacket, and the jacket has a large heat exchange area and a fast cooling rate. The motor and the stirring spindle are directly connected by a cycloidal pinwheel reducer, and the structure is simple, the operation reliability is high, and the maintenance is convenient.

Ribbon blender is widely used in putty paste, real stone paint, dry powder, putty, medicine, food, chemicals, feed, ceramics, refractory materials, etc. Solid-solid (ie powder and powder), solid-pulp (ie powder) It is especially suitable for mixing with viscous materials. For mixing materials with large fiber content and large difference in density, the mixer is not suitable. Putty paste, real stone paint, biology, medicine, food and other industries, it is recommended to use stainless steel. Under normal circumstances, mixing dry silt slurry containing vitrified beads, recommended horizontal ribbon mixer.
