The invention discloses a vibrating screen with superimposed frequencies, which can effectively solve the problem of mismatching vibration parameters in the simultaneous screening of coarse and fine materials, improve the screening efficiency of the vibrating screen, and reduce hole blocking. The multi-frequency high-efficiency vibrating screen is driven by two sets of relatively independent excitation units. The main vibrator provides large-amplitude, low-frequency vibration parameters to act on the entire screen machine to efficiently screen coarse materials; the vibrator provides small-amplitude, The vibration parameters of the high-frequency screen act on the lower screen surface to ensure accurate screening of fine materials; in addition, under the interaction of the two sets of vibrators, the main vibrator improves the blocking of the lower screen surface and can effectively remove jams. The material in the sieve holes increases the processing capacity of the vibrating screen and significantly improves the screening efficiency. It can be applied to the simultaneous screening of coarse and fine materials.
Description
technical field [0001] The invention belongs to the field of vibrating screening machinery. In particular, it relates to a frequency-superimposed vibrating screen for simultaneous screening of coarse and fine materials. Background technique [0002] The process of dividing mixtures with different particle sizes into several different particle size classes through a single-layer or multi-layer sieve is called sieving. Screening operations are widely used in mineral processing, metallurgy, construction, chemical industry, abrasives and other industrial sectors. With the development of technology, higher requirements are also placed on the screening effect, especially how to improve the screening machine for coarse and fine materials. The comprehensive screening performance, shortening the screening process, and reducing the number of screening machines have always been one of the hot issues in current screening science and technology research. Because according to the screen...
