As a result of the improved performance secured, the company was asked to provide four, high capacity, vertical screw blenders as part of a further plant upgrade.
Ajax Equipment undertook powder testing to assess the polymer granules bulk flow characteristics by measuring the bulk density, wall friction and shear strength of the polymer granules.
The results were used to design the blender base geometry and double outlets, ensuring the required mass flow of the polymer granules and rapid discharge.
The mixers have been designed for maximum capacity within a tight footprint and limited headroom, with a screw to provide a high re-circulation rate with mixing efficiency.
They use central 'fountain'-type mixing augers featuring special taper design with increasing pitch and taper reducing centre cone.
Lower sweep arms on the screws collect from the base of the blenders to provide rapid discharge.
David Barron, Global Project Engineer for Polymers at Kemira Water summarised the Ajax input to the project: 'As part of a Bradford site expansion project, we identified the need to increase our dry blending capacity.
We had previously worked with Ajax to improve the efficiency of two existing blender units and approached them to supply the new units.
Our decision was based not only on the Ajax technical specification, but also their willingness to work closely with the customer to identify the right requirements for the application'.
