300 series standard test sieves Product Overview: 300 standard sieve analysis is a powder grade, liquid filtration as one of the standard test sieves; for laboratory, quality control room of the particles, powder particle size analysis of structural precision, Liquid solid content and amount of debris tested. Low noise, high efficiency and high accuracy. Multiple high-frequency vibration to generate efficient screening samples; standard sieve to ensure that high-precision sample analysis; electronic delay device can be set with the same kind of material screening time as needed to ensure data consistency analysis of the sample, the test error minimized, so that the quality of products to make accurate judgments. 300 series standard test sieve mesh metal wire cloth, mesh requirements GB6003.1-1997 and perforated plates, mesh requirements GB6003.2-1997 two kinds. Mounted slap-style screening machine standard or standard-screen machines In use, the composition of the particle size of various powder materials classification. Widely used in precision standard sieve size detection and superhard materials (diamond, cubic boron nitride) abrasives, to Kansas, metallurgy, Pharmaceutical, chemical and building materials industries granular materials. Model: Φ200 * 50, Φ200 * 25 Our company produces high-grade standard stainless steel mesh sieve is used strictly in accordance with GB6003.1-1997 standards and selected by the microscope. Our labeling method using the specifications mesh / wire diameter (because mesh is relatively units refers to the number of mesh on one inch bore and 25.4 mm length wire. The same mesh, different wire diameter holes are different). 300 series standard screening test basic structure: 1. Standard sieve box using SUS304 (0Cr18ni9) polished stainless steel stretching from wall thickness of 0.6 mm, surface light can Kam, the overall shape of durable, non-magnetic, standard sieve sieve standard sieve frame fixed by soldering, not relaxation. Capability below 300 degree heat. Standard sieve frame made of SUS304 stainless steel stretch polishing, wall thickness 0.6-0.7mm, the surface light can Kam, durable, non-magnetic, standard sieve mesh standard sieve screen frame and fixed by soldering, not relaxation. 2. The mesh precisely, for the same size mesh by mesh mark so the timing of production of the same. Woven wire standard sieve, sieve pore size standard square holes up to 0.02 mm (20 microns) triangular aperture standard sieve pore size up to 0.005 mm (5 micron) standard sieve mesh weave by B6003.1-1997 standard. In line with international standards ISO3310-1: 1990 R20 / 3, R20, R40 / 3 series, standard sieve mesh brass H80, stainless steel SUS304. And electroplating, chemical processing can smooth screen surface wear, while weft yarn held together nodes, mesh long-term use is not deformed. Our company produces standard sieve size to ensure accurate, the same type of standard sieve mesh at different times to ensure the production of absolutely identical. To ensure the consistency of detection imports Tyler screen mesh size and GB6003.1-1997 similar, such as China 140 network 106 micron pore size, American Tyler mesh sieve No. 140 # 150 # 105 micron mesh size, we can produce according to user requirements can be chosen to provide users with a 105 micron mesh sieve Tyler appropriate, whether or mesh requirements appearance can meet the requirements. 3. punching board standard screen, press GB6003.2-1997 standard processing. In line with international standards ISO3310-2: 1990 R20 / 3, R20, R40 / 3 series. 300 series standard screening test methods of operation: 1. The standard test sieve to a horizontal position; make sure the power and the nameplate matches the requirements and to ensure that the ground; vibration portion can not be in contact with other objects; ministries bolts are tightened. 2. to determine the selection criteria to screen frame according to the material being tested and the appropriate standard. 3. Press aperture standard sieve frame from small to large, from bottom to top are stacked onto the screen frame base. 4. The test material was placed in a standard sieve box top, and cover with a standard sieve with a total height adjustment lever to adjust the height of the screen frame according to the standard, then the standard plate and lock nut for positioning the screen frame clamping ( NOTE: To force should be the same on both sides). 5. The material properties and the feeding amount, the timer is set to run on time, and then turn on the power switch, the standard test sieves began to work. 6. standard test sieves work stopped, unscrew the lock nut, remove the plate, carefully removed the standard screen frame. 7. off the power. More than 300 series of standards supporting Φ300 test sieve screen frame, the series of standard test sieve surface materials are divided into metal wire cloth test sieves and test sieves of perforated metal plate. Woven wire test sieves national standard GB / T6003.1-1997 production. Its basic mesh size 2.36mm-0.038mm, in line with international standards ISO3310-1: 1990 R20 / 3, R20, R40 / 3 series, the screen is made of brass, bronze, stainless steel. Test sieves of perforated metal plate national standards GB / T6003.2-1997, in line with international standards ISO3310-2: 1990 R20 / 3, R20, R40 / 3 series, the screen is made of copper, and electrochemical processing. Φ300 series of standard test sieve frame screen frame, screen cover and sieve bottom made of high quality stainless steel refining. Φ300 series of standard test sieve (screen frame composition) is mainly used to detect particle size analysis of materials, widely used in screening to detect abrasive manner worthy, metallurgy, Pharmaceutical, chemical and building materials industries granular materials.
