Equipment features

● The built-in countercurrent heat exchanger can efficiently recover waste heat, with remarkable energy saving effect, low fuel consumption and low regeneration cost.

The secondary roasting method is adopted, and the quality of reclaimed sand is excellent and uniform.

Low temperature roasting greatly reduces the damage of the furnace and air nozzle, and the roasting furnace does not need maintenance.

Low exhaust emissions, low temperature, dust waste heat recovery device can be miniaturized, saving investment costs and land.

● The full set of automation equipment adopts PLC control system, and the control panel is fully automated touch man-machine interface; the operation is simple and convenient, and the manpower saving can ensure the stability of production efficiency and product quality.

● A full set of automation equipment can be equipped with MES system to collect and store data; Traceability and query can be realized in the process of waste sand disposal.

● Can be used for waste heat regeneration.
