The No Tower Granulator (shortly NTG) is an equipment able to manufacture wet granulated product from powdered raw materials fed into the granulator along with set amount of liquids, normally water solutions.
Specially designed conditions must be met in order to allow for the formation of granules. Such conditions are: the correct balance of powdered and liquid raw materials, the turbulent effect of an excess air flow inside the granulation chamber and the agglomeration effect given by specific mechanical elements in the reaction room.
Compressed air is used to keep the flexible granulation chamber at a sustainable processing condition and to provide for atomization of the liquid injections.
A friendly Control Panel enables the operator to control the process from local or remote station. All production parameters such as motor rotation speed, liquid and powdered raw material intakes shall be controlled by a multipoint control system, able to allow the operator for provide timely and efficient adjustment should any upset occur.
The granulator is built at variable geometry by use of deformable materials in order to avoid any sticking of wet materials on the wall of the chamber. The key element are the deformable tubular chamber and the central shaft, driven by an electrical motor at variable speed. The shaftis provided with bolted in rotating devices at variable geometry. Outside the reaction chamber a set of 48 roller keeps the tubular chamber under flexible motion.
