Abstract

The invention discloses a vibrating screen capable of superposing frequencies, and the device can be applied to simultaneous screening of coarse and fine materials. The vibrating screen can effectively solve the problem of unmatched vibration parameters in the simultaneous screening of coarse and fine materials, improve the screening efficiency of the vibrating screen and reduce the hole blockagecondition. The complex-frequency efficient vibrating screen is driven by two sets of relatively independent excitation units in a combined mode, the main vibrator provides large-amplitude and low-frequency vibration parameters to act on the whole screening machine to efficiently screen coarse materials; the vibrator provides vibration parameters of the small-amplitude and high-frequency sieve to act on the lower-layer sieve surface, so that accurate sieving of fine materials is ensured; besides, under the interaction of the two vibrators, the main vibrator improves the hole blocking conditionof the lower-layer screen face, materials clamped in screen holes can be effectively removed, the treatment amount of the vibrating screen is increased, and the screening efficiency is remarkably improved.

Description

technical field [0001] The invention belongs to the field of vibration screening machinery. In particular, it relates to a frequency-superimposed vibrating screen that solves the simultaneous screening of coarse and fine materials. Background technique [0002] The process of dividing a mixture of different particle sizes into several different particle size grades 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 put forward for the screening effect. Excellent comprehensive screening performance, shortening the screening process, and reducing the number of screening machines have always been one of the hot issues in today's screening science and technology research. Because according to the sieving theory, the sieving movement consists of two parts: stratifi...
