[0045] Working principle:

[0046] 1. Granular materials (i.e. feed) flow out from the middle barrel and fall onto the conveyor belt through the discharge port. The conveyor belt will move the appropriate amount of granular material layer to the other end at a uniform speed. A weighing sensor is installed under the conveyor belt. A certain material layer weight presses the conveyor belt, so that the conveyor belt presses the weighing sensor during the movement, generates electronic data for the weighing system and calculates the output data, controls the frequency converter to generate reasonable frequency conversion data and provides it to the reducer, so that the appropriate amount of material passes through the conveyor belt and enters the barrel.

[0047] 2. When the material enters the cylinder, it is turned up by the material-discharging blades in the drum, falls down after reaching a certain height, and produces a continuous tumbling and falling material flow, which rolls forward and is turned over by the turning mechanism at the same time. During this process, the oil pump of the oil injection system passes the liquid grease through the oil injection pipeline, and enters several nozzles in the drum under the injection of compressed air, forming a mist-like oil mist and spraying it out. The tumbling material layer particles continuously absorb and adsorb on the surface and inside of the particles, achieving the effect of the material being sprayed with oil.

[0048] 3. The material tumbles and moves continuously, and is absorbed by the oil atomization. After the oil spraying function is completed, the material is discharged out of the drum through the drum discharge port, completing the oil spraying effect.

[0049] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
