This series of water solvent spray dryingand granulation equipment is applied to the dry granulation of cemented carbides mixing slurry using water as liquid medium. It adopts dried air as heat carrier and directly heated by electric resistance wires, with no heat exchanger or heat container, no  protection gas or individual ventilation device, no air-tightness requirement,and no residual waste to deal with, it has the obvious advantages of low invest expenses and operation cost, safe and reliable, environment friendly and can guarantee the quality of cemented carbide or W & Mo mixture. It is a equipment of domestic initiation.
