The frequency-modulated vibration sieve (Somerville type Vibration sieve) is used to sieve impurities in Stock and determine the content of impurities such as fragments in Pulp. The use of this sieve in pulp and paper laboratories can reduce the number of impurities in Pulp suspension that do not meet the process requirements, resulting in clean and good pulp.

The measurement of diluted pulp suspended water rate was carried out by Schopperr-Riegler test method, with a range of 1~ 100SR, which conforms to ISO, GB/T, QB/T standards.

Screening area 54200m ² and Vibration Frequency 400-1000 times/min adjustable. The instrument adopts frequency modulation vibration design, the screen plate is easy to disassemble, can be equipped with a round hole screen, small size and easy to operate.

Used for measurement of water filtration rate of diluted pulp suspensions, it features an adjustment mechanism, a design of manual compression sealing vertebrae, and a three-legged leveling mechanism to ensure good sealing between the sealing vertebrae and the cylinder. The instrument is suitable for quality control of diluted pulp and laboratory research.
