New wiper assembly breaks lumps, agglomerates

A new independently driven Wiper Blade Assembly available on FLO-THRU screen separators breaks down lumps and agglomerates and prevents screen blinding more effectively than passive wiper blades driven by screen vibration, according to Henry Alamzad, Kason's vice president of sales and marketing, USA operation.

The support arm of the assembly is mounted to the unsprung base plate of any FLO-THRU separator, allowing independent, secure adjustment of wiper blade height above the vibrating screen surface or at screen level. The action of an oscillating screen surface beneath a fixed height blade, together with independent adjustment of blade rotation speed, from 1 to 15 RPM, enable the user to achieve higher, more controlled de-lumping efficiency and screening capacity than possible using conventional wiper assemblies which are rotated by vibratory induced friction.

Flexible rubber wiper blades or bristle brushes can be affixed to the agitator shaft arms to maximize de-lumping and anti-blinding results for individual materials.

Kason Flo-Thru screen separators are distinguished by their externally-mounted gyratory motors, low profile shape, and straight-through material flow path. Units equipped with the new Wiper Blade Assembly are available in stainless steel in industrial, pharmaceutical, and food-grade finishes.
