The machine is equipped with a heating sleeve on the heating funnel, and the heat source uses hot water, heat transfer oil, and low-pressure steam to keep the inner wall of the funnel at a certain temperature. The frequency conversion motor rotates the single spiral mixer through the parallel spiral gear reducer, so that the material rotates along the conical cylinder and pulls from bottom to top. After the material reaches the highest point, it automatically flows to the vortex center and returns to the bottom of the conical cylinder under the action of gravity and inertia. The whole process makes the material forcibly heated in the conical cylinder, with relative convection and mixing. The heat diffuses in the material to make the material move irregularly in all directions, the high-frequency heat transfer and exchange of the material with the single screw belt and the surface of the cylinder wall are completed, and the effect of heating and drying is achieved in a short time. In order to make the material internal water evaporation, under the action of the vacuum pump, water vapor from the vacuum pump, such as the need to recover the liquid can be added condenser, recovery liquid storage tank recovery. After the drying is completed, open the lower discharge valve to discharge the material.

The internal heating fluidized bed drying technology is an advanced drying technology developed on the basis of ordinary fluidized bed drying and indirect conduction drying. The tube heat exchanger is built into the fluidized bed, and the fluidization technology is applied to strengthen the heat transfer between the solid particles and the heat medium, and the drying thermal efficiency and drying intensity of the dryer are improved.

The horizontal ribbon mixer for battery materials consists of a mixing chamber body, a stirring device, a driving device, etc. The O-shaped tubular chamber is equipped with a double-layer different-direction ribbon coiled stirrer shaft. The outer spiral belt is driven by power, and its coiled form matches the rotation direction to push the material from the two ends of the O-shaped chamber to the central zone, while the inner spiral belt pushes the material from the middle to the two ends to form convection mixing. At present, the loading volume of the largest model produced by our company has exceeded 30m ³.

The positive pressure dense phase pneumatic conveying system uses compressed air as the conveying medium. Material in the pipeline at a lower speed, dune state, fluidized or agglomeration state of transport is called positive pressure dense phase pneumatic conveying. The air source generally used is an air compressor, and the conveying pressure can be from 0.2MPa to 0.5MPa according to different working conditions.
