Test Sieve Shaker features 1 to 8 sieve working layers which rotates at speed of 1400 rpm for fine particle distribution analysis. With diameter of 200 mm sieve, it can test 50 to 150 g of sample material. Used to determine particle size distribution of raw and finished materials in the form of particles, powder and liquid. A Test Sieve Shaker is a laboratory instrument used to shake a stack of test sieves in order to efficiently separate particles of different sizes. The primary purpose of this equipment is to perform particle size analysis and ensure the consistency and accuracy of the results in various industries, including pharmaceuticals, food, chemicals, and construction.
