Stainless Steel Sieves - Metal Wire Cloth TypeTest Sieves JIS Z 8801 Standard

Metal Wire MeshAccording to the JIS standard, the metal wire mesh of sieves is defined such that each metal wire should cross vertically, shaping a regular square as the aperture for screens (flat weave). When one side of the square (aperture) is less than 45 μm, the mesh may be woven into twill by wires (twill weave). To comply with the JIS standard, Tokyo Screen embraces two types of wire cloth: (1) flattop weave when the aperture is over 2.36 mm, and (2) twill weave when the aperture is less than 38 μm.

●Flattop Weave Mesh ● Flat Weave Mesh ●Twill Weave Mesh

Twill weave mesh is structured by crossing two parallel wires with each other in one uneven pattern. The mesh is woven using thick wires and is good for screening small particles.

Aperture

Flat weave mesh is basic as each wire crosses vertically to keep the aperture squares stable in the screen. This standard cross enables accurate and effective screening.

Aperture

Flattop weave is used for screening large and middle-size particles. The surface of the mesh is designed to be flat and smooth.

Ultrasonic Vibration Sieving System Type TSK-UDSUltrasonic Vibration Sieving System Type TSK-UDS

The ultrasonic vibration sieving system enables dry sieving of fine powder with 5 to 15 μm micro-screens when the vacuum pump and ultrasonic sieving machine TSK-PNS (ultrasonic frequency: 30 to 38 kHz) are set on the exclusive housing. As a matter of course, the JIS Z 8801 wire nets can be used with it. Replaceable nets are applicable to sieving of various fine powder samples. The clamp detaching structure can be used easily by anyone, the sieving efficiency of fine powder is improved, and fine powder, which could not be sieved until now, can be sieved. The specifications can be changed into the two-stage type, though the standard type is the one-stage type.

Vibration and HorizontalTapping Combined MotionThe Test Sieves Shaker is the application machine that generates vibrations and horizontal tapping motions for sifting sieves. The shaking motion is combined with a circular motion (vibration) and shockwaves to multi-laid sieves, resulting in efficient screening tests (available for the adjusting the strength of the motion). The shaker is more compact than devices currently in use and can be placed on a desktop without screws or bolts. The model is the most suitable for laboratories because of the low noise level.

Figure-eight Swing Rotation and Horizontal Tapping Test Sieves Shaker TSK B8-1 shakes all sieves simultaneously in a figure-eight motion to make particles widespread on each layer of mesh. Additionally, the unit adds horizontal tapping to each sieve to accelerate the screening process. This function shortens the test time for accurate results. The tapping shock is horizontal in the same direction as the figure-eight swing rotation. This parallel combination prevents the particles from hopping inside each sieve to make screening more efficient and stable.

Brushes for Test Sieves

JIS Z 8815-1994 Tables 2 and 3

Tokyo Screen provides standardized brushes for test sieves (JIS Z 8815-1994). As the standard prescribes (6.1.1 and/or 6.2.1), the brushes clean the remaining particles through the mesh without damage to the screen. Along with the standard (description pp. 5 and 14), the brush should not press the screen mesh too forcefully and must move in the same direction as the aperture layout. The standard designated appropriate bushes in Tables 2 and 3.
