Multistage whirling vibration screening method

Abstract

The invention introduces a multi-stage rotary vibration screening method, which includes the use of a multi-stage rotary vibration screening device. The process is as follows: a power mechanism and a rotary mechanism are installed on the multi-stage rotary vibration screening device, and the power mechanism is connected to the motor support through bolts. On the top, weld the motor support to the left side of the box, and connect the power mechanism to the rotating mechanism through a V-shaped belt; connect the rotating mechanism to the upper support plate of the box through rolling bearings, and set the feeding port on the upper support plate ;The secondary screening mechanism is installed on the eccentric shaft of the rotating mechanism through the sleeve, and the primary, tertiary, and quaternary screening mechanisms are set; the raw materials are added to the primary screening mechanism, the device is started, and the raw materials pass through the primary screening in turn Mechanism, second-level screening mechanism, third-level screening mechanism, and finally discharge through the fourth-level discharge device. The multi-stage screening device adopted by Lili adopts belt transmission, which plays the role of buffering and absorbing vibration. The eccentric shaft drives the concave screening device to vibrate and rotate, and the screening is sufficient. The device occupies a small area. demand.

Description

technical field [0001] The invention relates to a technology in the field of screening, in particular to a multi-stage rotary vibration screening method. Background technique [0002] In the metallurgical and mining industry, vibrating screens, crushers and other equipment are generally used in China to form a material processing system. However, in the production process, it is inevitable that the crusher or vibrating screen equipment will be excessively worn at the point where the material falls or the crushing length and screening will not be effective. The problem of small area leads to low production efficiency and the phenomenon of large horses and small carts. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-stage rotary vibration screening method, which achieves the purpose of sufficient screening, small footprint, and meeting the needs of modern production. [0004] In order to achieve the purpos...
