Steps 1, the device should be placed high-level screening test, make sure the power and plate requirements in line and make sure the ground; note vibrating part can not be in contact with other objects; checks ministries bolts are tightened. 2, according to the material being tested and the appropriate criteria to determine the criteria to choose the screen frame. 3, the standard screen frame by small to large test sieve aperture, from bottom to top on the stack to test sieve machine vibration. 4, the material will be placed in a standard test sieve box top, cover with lid standard sieve, sieve standard frame height adjustment lever height adjustment based on the total, followed by the standard plate and lock nut positioning screen frame compression ( Note: The sides of the force should be the same). 5, according to the material properties and the feeding amount, the timer is set to run on time, and then turn on the power switch test screen models, standard sieve began to work. 6, after the standard screen work stopped, unscrew the locking nut factory test sieve, remove the plate, carefully removed the standard screen frame. 7, off. 1, the screen surface having a regular arrangement and the shape, the same size of the surface pores. 2, sieve sieve sieve surface mounted box for screening devices. 3, a pilot test sieve sieve sieve conform standard specifications for materials used to treat sieve size analysis. 4, test sieve sieve set in accordance with the provisions of the cover, splice tray assembly of a group of five test sieves, test sieve designated qualified institutional inspection, verification, test sieve considered conforming.
