Description

Technical Field

[0001] This utility model relates to the field of metal ore screening technology, specifically a vibrating screening device for metal ores. Background Technology

[0002] In industrial fields such as metal ore mining and metallurgical processing, vibration screening is a core step in achieving ore classification and purification. Its screening efficiency and classification accuracy directly affect the cost and product quality of subsequent processing technologies. During the metal ore screening process, ores of different particle sizes need to be separated to provide raw materials that meet particle size requirements for subsequent processes such as grinding and flotation. Therefore, vibration screening devices need to be adaptable to metal ores with different characteristics while meeting the efficiency requirements of continuous production.

[0003] However, existing vibratory screening devices for metal ores have many technical drawbacks in practical applications, making it difficult to meet the requirements for efficient and accurate screening. Because the position of the vibratory motor is fixed and the point of application of the excitation force cannot be adjusted, the device can only be adapted to ores of a single particle size or characteristic. When faced with large, sticky or fine-particle-proportioned ores, problems such as screen blockage and poor stratification of loose ores are prone to occur, resulting in a significant decrease in screening efficiency and grading accuracy. Therefore, improvements are needed. Utility Model Content

The first hydraulic cylinder drives the U-shaped frame to move left and right along the limit rod and slide groove, flexibly adjusting the excitation force application point of the second vibrating motor to adapt to metal ores of different particle sizes and characteristics. This not only enhances the loosening and stratification effect of the ore and avoids material blockage on the screen, but also optimizes the material movement speed and screening rhythm, greatly improving screening efficiency and grading accuracy.

[0018] 2. In the feeding mechanism of this vibrating screening device for metal ore, the second hydraulic cylinder drives the baffle to slide the adjusting plate in the feeding hopper. The feeding amount and feeding speed can be flexibly adjusted according to the screening progress and ore characteristics, avoiding screen overload and blockage due to excessive feeding or production efficiency impacted by excessively slow feeding. This achieves precise matching between feeding and screening. The drive motor drives the first crushing roller and the second crushing roller to mesh and rotate, which can directly pre-crush large pieces of metal ore, making the ore particle size suitable for the processing requirements of the vibrating screen. No additional crushing equipment is required, simplifying the process flow and reducing equipment investment costs.
