Test sieve is a more sophisticated equipment, widely used in laboratory, quality control room inspection departments particle size distribution measurement of powder materials, product impurities, determination of liquid solids content analysis. Test sieves dedicated power generator using the new test sieves price, high-frequency vibration generated pluralism, efficient screening samples to ensure the accuracy of the standard sieve test sieve manufacturers, installation of electronic delay test sieve, sieve time can be set arbitrarily, with low noise, high efficiency, high precision, while according to the different materials to achieve different working hours by electronic delay, the test to minimize errors and ensure the consistency of test sieves sample analysis model data, product quality do exact judgment. Standard test sieve is a laboratory screening machine, also known as test sieves, sieve-like, sieve analysis, mainly for university labs, research institutes or some internal laboratory use. It is different from the vibration screening machine, which is the national standard, the standard test sieve machines and standard test sieve frame has a certain standard limits.
