The raw materials of this experimental platform are clay, sludge, fly ash and other raw materials that can be ground into powder. The moisture content of the materials should be controlled at about 15%.

The raw materials enter the vertical mill through the raw material loading bin and the vibrating feeder for grinding, and the vertical mill powder selection system takes the qualified powder into the bag filter for powder collection. The collected powder is conveyed to the bucket elevator through a screw conveyor, and the bucket elevator lifts the powder to the batching bin. The qualified air is discharged into the chimney through the fan. The powder is fed to the screw conveyor after passing through the batching system under the silo, and then to the bucket elevator. After the powder is brought out from the hopper, it enters the double-shaft mixer for mixing. If the water content of the material is not enough, add water until it is suitable for the disc ball machine to form a ball. The ceramsite made from the ball-shaped disc is transported to the rotary kiln through a large-angle belt conveyor for calcination. The calcined finished ceramsite is cooled by a vertical cooler, and the cooled ceramsite enters the finished product storage through the belt conveyor. The kiln tail flue gas is cooled and dust collected through an air cooler, and then returned to the vertical mill to heat the raw materials to achieve energy-saving effects. The process design of the entire production line is simple and easy to operate.
