The ribbon mixer is composed of a U-shaped container, ribbon mixing blades and transmission parts; the U-shaped long cylinder structure enables the mixed material (powder, semi-fluid) to move with small resistance in the cylinder. The positive and negative rotating spirals are installed on the same horizontal axis to form a low-power and high-efficiency mixing environment. The spiral ribbon blades are generally made of double or triple layers. The outer spiral gathers materials from both sides to the center, and the inner spiral Conveying the material from the center to both sides can make the material form more eddy currents in the flow.Speed up the mixing speed and improve the mixing uniformity.
