Test sieve calibration standards, Han Machinery (certified), Xinxiang test sieves by Han Machinery Co., Ltd. of Xinxiang City. Xinxiang City Han Machinery Co., Ltd. (xxdh.b2b.hc360.com) is specialized in the "ultrasonic vibration sieve sieve shaker test" of the enterprise, the company of "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: sinus super. DH test standard test sieve sieve works YZU vertical vibration motor is used as the source of vibration machine, vibration motor driven by the upper vibration plate vibration, the vibration plate through conduction to the vibrating plate placed in the upper screen frame casting Φ200 test sieve, and then by the need to detect the mesh size of the screen frame is smaller than the screen surface mesh screening material particles to lower screen frame, so the layers of screening, so just stay the same size within each test sieve test sieve material wholesale, to different particle sizes isolated and size composition of this material test sieve, sieve the material Φ200 type box can play a very effective filtering, classification, screening purposes. Standard test sieve test sieve metal braid short test sieves, also known as the standard test sieve (sieve test), standard sieve analysis is widely used in research and production of metallurgical, chemical, pharmaceutical, cement, building materials, defense, geology and other departments, the test room, quality control room and university laboratories for granular, granular structure of powder materials, liquid and solids content of the class of exact amount of debris screening, filtering, detection, are also commonly used in ordinary abrasive particle size composition of inspection grading and superhard materials production and other fields.
