1.       Productintroduction HLHigh-frequency vibrating screen with a high frequency . On one hand it destroysthe surface tension of ore pulp and the high-speed concussion of thefine-grained materials in the sieve surface, on the other hand the high-speedoscillation increase the contact probability between materials less thanseparation granularity and the screen surface. Thus formed better separationconditions make the materials which particle size less than normal, especiallythe big proportion materials, sieved through into the next screen with ore pulptogether. High-frequency vibrating screen enjoys many features such as reliablestructure, strong vibrating, high screening efficiency, low noise, durable, easymaintenance and safe operation. It is widely used in the product classificationlike mining, building materials, transportation, energy, chemical land other industry. 2.       Feature 1) Smallvolume, light weight, easy installment and movement, height can be adjustedfreely. 2) Highprecision screening, high efficiency, can be applied to any powder, grain, mucusmaterial. 3) Highfrequency up to 3,000 turns/min, sieving effect is more apparent on the fine-grained,high-viscosity materials. 4) Uniquemesh structure and convenient installation work. 5) Exceptvibration motor, all parts are in all stainless steel, beautiful appearance andhygiene. 3.       Applications Excellentapplication for the dry material grading and serous fluid filtering such as chemical,food, medicine, non-metallic minerals, metallurgy, abrasives, ceramics, rubber,plastics, construction materials, coatings, paints, paper, petrochemical, military,environmental protection, urea, brewing and other industries. 5.       Notes 1) Powerswitch (not use knife switch) and ground wire should be ensure well contact,non-electrical power to run, otherwise it will cause the motor burning. 2) Themachine should be placed in the distance 500mm around to avoid a collision. 3) finemesh replacement method: * Loosenthe six plastic head nut, remove the upper hopper and network ring. * the finemesh should be placed on the network ring level up. * making thecircle tightening controlled by longing on pressed into the bottom of theannular groove and tighten. * Repeatthe above steps to tighten control pressed into the upper annular groove andtighten. * Usescissors to cut off excess mesh. 6.       Maintenance 1) cutoff the power when not in use. 2)non-rinse cleaning the motor to prevent leakage. 3) keepingthe screen clean to get the best filtering effect, when cleaning screens, you don’thave to stop, you can according to the different filter material to use ofappropriate cleaning agents, such as mud can be washed with water, but prohibitedsharp hard colliding with the mesh.
