The vibrating screen features a robust, maintenance-friendly design. Production rates as high as 15,000 TPH & cut sizes from 48 mesh to 10 in.

For vibrating screens, the equivalent dynamic bearing load, P, can be estimated using: = 186 kN. The load ratio C/P = 1357/186 = 7,3. SKF rating life 1. Lubrication condition – the viscosity ratio, κ. κ = ν/ν 1. The rated viscosity v 1 = 10 mm 2 /s .

Vibrating screen equipment in mineral processing has a tough job. The eccentric motion with high vibration coupled with heavy loads puts a strain on components, and especially bearings that are exposed to the elements and abrasive dust. It's an environment where equipment failure is often accepted as a cost of doing business.

clearly seen. Screen panel size is 28 by 54 inches. The oversize return tube turns with the trommel These things are not small. The diameter of the trommel for the 34-foot mill is 13.5 feet and the screen surface length is almost 13 feet. This gives us about 550 square feet of screen area, for roughly 30,000 tons a day or 1,300 tons an hour.

A separate discharge flange sends the product size material for further processing. 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. This provides 20 ft² (1.858 m²) to 175 ft² (16.258 m²) of both overs and fines ...
