Trio Horizontal Screens

Trio Horizontal Screens

All TRIO horizontal screens have huck bolted construction and generate their power via three timed shafts with eccentric counterweights.

The combination provides an oval stroke forward motion that can be adjusted in amplitude, speed and operating angle depending application, feed size, and gradations. The units utilize a fully-contained oil bath lubrication arrangement. The units are all shipped standard with sub-frames, motor mount, v-belt drive guard, coil springs and lined cross members.
