Pneumatic Type Beating & Freeness Tester (UEC-2002 B)

This instrument is used for determination of refining as freeness of wood fibre, ground wood Mechanical pulp and recycle fibers. It measures the drainage capacity of beaten pulp and checking the progress of beating process. Model with provision of Pneumatic controlled valve lifting and Plexiglas measuring cylinder for Schopper Riegler value with standard wire mesh.    

A stock dilution of 2 Grams/Ltr. is poured into the cylindric container. After 5 seconds the sealing cone is lifted at an after the acceleration constant speed rate, and the stock is drained through a wire, passes through the side orifice, and is a measure of the draining capacity of the sample.   Pneumatic arrangement ensures a constant lifting rate for the sealing cone. The equipment is intended for long fibered pulps that produce a dense fibre mat on the screen.
