Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] A cyclone negative pressure screen comprises a screening system, a vibration system, a material separation system, a cyclone negative pressure system and a support system.

[0022] The screening system is mainly composed of a screen box 2, a screen box support shaft 7, a screen fixing device 37, a screen 36, and a screen 38, wherein the screen box 2 passes through the screen box support shaft 7 on the screen box at a certain inclination angle. , The screen box support base 8 and the shock absorbing device 9 are fastened on the support system, and the surface of the screen is sprayed with wear-resistant polyurethane material to enhance the compression and wear resistance of the screen, reduce the replacement frequency of the screen, and the screen fixing device 37 is installed on both sides of the inside of the screen box 2, and the upper and lo...

Abstract

The invention provides a rotational flow negative pressure sieve. A device of the rotational flow negative pressure sieve uses a sieving system, a vibration system, a material separation system, a rotational flow negative pressure system and a support system; the sieve fraction level of materials can be effectively controlled; the material dry sieving efficiency is improved; the production workshop fine dust is synchronously reduced; the problems of energy consumption and environment pollution caused by low sieving efficiency and serious dust pollution of the device can be solved.

Description

technical field [0001] The invention relates to a screening device, in particular to a fine-grained negative pressure dry screening equipment. Cyclone negative pressure sieve. The cyclone negative pressure screen uses a high-frequency electromagnetic exciter to vibrate the screen surface, and uses an independently configured cyclone negative pressure system to realize the classification and separation of fine mineral particles, and realize the simultaneous operation of screening and dust cleaning. Higher, it is better to control the particle size of the material after being screened by the cyclone negative pressure sieve. Background technique [0002] In recent years, with the continuous depletion of ore resources and the continuous improvement of beneficiation technology, the application of "more crushing, less grinding, and early throwing" technology has attracted more and more attention. Especially for my country's iron ore resources, the current mining grade of magneti...
