Standard test sieves are YZU vertical vibration motor as vibration source machine, vibration motor driven by the upper vibration plate vibration, and then through the vibration plate vibration transmission to be placed on the upper plate Φ200 screen frame, and then the screen frame is necessary to detect the mesh The screen surface is smaller than the mesh screening material particles to lower screen frame, so the layers of screening, so that the material within each test sieve, leaving only the same size, to achieve separation of different particle size and to determine the composition of this material, so Φ200 type Material sieve box can play a very effective filtering, classification, screening purposes. 1, in strict accordance with customer needs and site requirements screening test models, providing compliance with design standards, quality standards of products. 2, strict inspection and control of raw materials, the original device, component parts into the plant quality. 3, to ensure the perfect process for equipment, detection means complete. Products not manufactured with a defect. 4. I will promptly notify the demand side, quality defects occur during the execution of the contract, do not hide. If the equipment exceeds the scope of the contract defect test sieve manufacturers, the company responsible for the unconditional replacement. During the installation and commissioning of the test sieve manufacturers, equipment quality problems, the first deal with the problem, then clearly define the responsibilities, all in order to meet the project schedule needs to be guidelines. 6, equipment manufacturing, transportation, loading and unloading of the company for the insured event of an accident, I will ask for the demand side of the device into the line as soon as possible for a free replacement, repair, until the demand side satisfied.
