SCREEN CAPACITY CALCULATION
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
Triple Deck Vibrating Screen Machines
J&H provides a full range of sizes from 4′ (101.6 mm) wide x 5′ (127.0 mm) long up to 7′ (177.8 mm) x 25′ (635.0 mm) long, designed in 5′ (127.0 mm) length increments.
