What criteria is used for choosing the proper Feeder?
Some of the criteria for choosing the proper Feeder includes: 1. Gradation and lump size. First, consider the gradation of the material the Feeder will handle. Be sure to include the largest lump size (even if it is less than 1% of the total gradation) as well as the smallest particle size in this analysis. 2.

Advances in screening technology in the mining sector
The screen decks, which operate in parallel, are equipped with high performance polyurethane screen panels. The screen is excited into linear vibrations by two vibratory motors. The high-frequency linear vibration generates an acceleration in the material on the screen, so that the slurry on the screen lining experiences a longer residence time.

What are vibrating screens and which are its main applications for use. Also called simply screens, a vibrating screen is formed by a vibrant chassis that supports in its interior one or several surfaces or elements of screening. The screens serve to classify the different particles by size, starting from a bulk product in a continuous process.

All About Vibrating Conveyors
There are three main drive mechanisms used in vibrating conveyors: cranks/springs, rotating weights, and electromagnets. Crank or spring-type conveyors are what is visualized in Figure 1, where a four-bar mechanism is rotated by a motor, imparting an elastic force that causes sinusoidal motion. Rotating weights and electromagnets accomplish the ...
