(1) Dry screening methodTs0Textile Testing Instruments, Testing Equipment Manufacturer

1. Cut the sample 5×n Block n is the group number of selected particles. During the formaln testing, the standard granules and samples should be conditioned according to the regulations. Ts0Textile Testing Instruments, Testing Equipment Manufacturer

2. Lay each sample in the same group flat and without creases on the supporting mesh screen, which can support the sample without sinking. Ts0Textile Testing Instruments, Testing Equipment Manufacturer

3. Choose a standard granulate with a finer particle size, weigh out 50g and spread evenly over the surface of the sample. Ts0Textile Testing Instruments, Testing Equipment Manufacturer

4. Clamp the sieve frame, sample and receiving tray onto the vibrating sieve machine. Start the machine and shake the sieve sample for 10 minutes. Ts0Textile Testing Instruments, Testing Equipment Manufacturer

5. After shutdown, weigh and record the mass of standard granules flowing through the sample, then replace a new sample set. Ts0Textile Testing Instruments, Testing Equipment Manufacturer

6. Repeat the procedures given in 2-5 with the next group of coarser standards until the sieving rate of not less than three groups of continuous grading standards is achieved and one sieving ratee of a group less than 5%. Ts0Textile Testing Instruments, Testing Equipment Manufacturer

II Wet sieving processTs0Textile Testing Instruments, Testing Equipment Manufacturer

1. First weigh the dry weight of the sample and then soak it in water with wetting agent until saturated for at least 12 hours. Ts0Textile Testing Instruments, Testing Equipment Manufacturer

2. Take the sample out of the water and clamp it flat and tension-free in the clamping device. Ts0Textile Testing Instruments, Testing Equipment Manufacturer
