The new national standard powder screening sieve is based on the new national standard GB/T5507-2008 "grain and oil inspection powder thickness measurement" independent research and development of the powder thickness fineness test sieve. Powder screening is one of the most important instruments for grain and oil testing. Others include gluten tester, drop value tester, flour whiteness tester, etc., which play an important role in grain and oil testing. The principle of powder screening is that the samples are sieved on different specifications of sieves to achieve different particle separation. The thickness of the classified grain is calculated based on the amount of residue on the sieve.

Round powder screening sieve consists of three parts: the chassis, rotary tray, and sieve body. The chassis is equipped with a motor, belt transmission components, balance devices, timers, and the like. Rotary trays are mounted on eccentric bearings. The screen body consists of a screen bottom, a screen grid, and a screen cover. It is generally stacked with 7 layers of screens and secured by two tensioning screws. The motor drives the eccentric wheel, and the entire screen body rotates like a high square screen, so as to achieve an ideal screen effect. The round type powder screening structure adopts a worm gear pair with low center of gravity and high precision for variable speed transmission. Through the eccentric linkage mechanism for planar rotation, under the action of the internal balance device, the operation is more stable, and the pressing lever integrated with the tray is integrated. The seat makes the screen more reliable and easier to operate.
The new national standard powder screening adopts the desktop structure, low-speed motor drives, the screen body is supported by three planes, the screen grid is fixed on the pallet by two pressing hooks, and the plane rotation movement is performed through the eccentric mechanism, and a balance device is provided to make the operation. Keep the whole machine stable. The new national standard powder screening electronic timer for timing control, high timing accuracy. In addition, the new GB powder screening machine has the advantages of compact and reasonable structure, stable operation and convenient operation. In terms of scope of use, the new national standard powder screening is applicable to the detection of the processing precision of flour, starch, rice flour, compound feed and other powder materials. It can also be used to inspect whether the sieves and screens of these processing plants are damaged. Determination of the best detection equipment.
