Máy đo độ nghiền bột giấy SR

For the determination if the degree of refining (beating) of a pulp suspension in water and expressing it in terms of the Schooper-Riegler (SR) number, and to determine the dewatering time

Applicable Standards: ISO 5267-1 / SCAN C 19M3 / BS 6035/1

Description:
The Schopper-Riegler apparatus measures the degree of work done on the fibres during stock preparation frefining) and is therefore a primary tool in the evaluation of the characteris- tics of pulp. The apparatus consists of a drainage chamber and rate measuring funnel on a sturdy support. The drainage chamberis fitted with a wire screen (100 cm') at its lower end and is sealed 25 mm above the screen when the sealing cone is lowered. After filing 1 litre of suspension into the draina- ge chamber the sealing cone is raised pneumatically. As the filtrate drains into the rate measuring funnel a fibre pad is formed on the Screen, slowing down the process demending on the mechanical treatment to which the pulp has been subjected. The discharge from the side orifice is collected in a graduated cylinder, measured by an ultrasonic sensor and the result displayed digitally. The instrument is furnished with a bayonet fixing for quick and easy removal of the upper part of the drainage chambers. The pulp can be removed from the Schopper Riegler screen and dried for determination of dry weight.
