Thunderbird II screens are easy to work on and with.
There is little maintenance; checking the oil level occasionally
is all that is required. Screen cloth is easy to change; all
screen cloth tensioning bolts are readily accessible.
Screen cloth is held with hook type abrasion resistant steel
drawplates, carriage bolts and aligning washers.
Our screens
come complete with base frames, motor mounts, drawplates,
springs, guards and a driven sheave. The vibrating basket
is made from A-36 steel on all structural members that are
oversized for added strength. The feedbox has A/R wear
liners as do the discharge lips. For added durability the
sideplates have a reinforcing doubler plate in the vibrating
shaft area.
Thunderbird II screens feature an adjustable
stroke for maximum performance and flexibility.
The bearings are standard off the shelf
spherical roller bearings and run in an oil bath. The
tapered bore bearings are mounted on a replaceable tapered
spindle and held in place with a standard bearing nut and
washer. This makes changing a bearing quicker and easier.
This design makes an excellent wash screen. The cooling
affect of the water doesn't reduce the bearings internal clearances,
and therefore, the bearing life.
The shaft carries no bearing or basket
weight and contaminants are kept out of the oil case by either
a labyrinth unitized cartridge seal or a combination piston
ring and neoprene contact seal for positive dirt rejection
and oil sealing.
All moving parts are enclosed in oil
tight cases with an air breather and run in standard lubricant
oil. No cooler, oil mist systems, etc., are needed.
