High frequency griddle is high efficiency, small amplitude. It is different with screening principles of the general screening equipment, due to high frequency griddle using a high frequency, on the one hand break the surface tension of the ore pulp, on the other hand because fine material high-speed oscillation on the griddle surface, increase isolation of large density useful minerals, increase touch opportunity of less than sieve size and sieve pore. so that the material of less than the separation size and ore pulp drop down together through the sieve pore. 
   High frequency griddle is widely used in mineral processing, coal preparation, chemical, brick, food, pharmaceutical, alkali, fertilizer, paper and other industries for a variety of materials dry, wet screening, grading, dehydration. in classification processes for the fine grading operations, Under the conditions that the appropriate concentration of feed ore, feed ore particle size (-200 mesh size fraction), and difference the expected size and the feed size is less than 30 percent, the screening efficiency up to more than 70%.
