percentage of small feed material the greater the screen capacity. The faster the material passes through a screen the more open area there is left to screen the remaining material. A feed material with 40% of the feed being half the opening size or smaller equates to a factor of 1.0 . Figure 6 uses the percent of feed material half the

Typically, the length of the screen is 2.5 to 3 times the size of the width. Every manufacturer has its own screen sizing formula. Screens are tailored to an operation based on the following factors: Basic capacity – how much material is going to pass through a certain opening. Incline – how much of an incline, if any.

High-frequency vibrating screen is usually operated at an inclined angle 0°-25°, up to 45°, and the operating frequency range is 1500-7200r/m. 7. Grizzly Screen. Grizzly screen is often used for pre-screening before coarse and medium crushing of materials. The mesh size is generally >50mm, but sometimes <25mm.

Area calculations are made separately for each screen separation; the size of screen being selected on the basis of the critical deck or separation requiring the largest area. The basic formula for arriving at the deck area required for a given size separation is dependent on tonnage of undersize in the feed and capacity per sq. ft.
