EIMCO-K.C.P. Thickeners are available in different types and sizes for every kind of service for the chemical, mining, pulp and paper industries and for industrial waste treatment. The drives are of beam, truss or center column supported or traction types. Automatic rake lifting devices and center column pumping are available. Special arms are provided for dense slurries. Main gears in drive-heads are of special steel, designed for wear resistance, surface durability and strength for high-torque applications. Waste treatment thickeners are available with center column pumping to avoid cost of tunnels.

LIFTING DEVICE

A lifting device can be provided for either the type B or type C mechanisms. This device raises and lowers the rake arms to accommodate increasing or decreasing loads on the rake arms.

The type B lifting device can be supplied with either a manual or motorized 24” or 36” lift

The type C lifting device is supplied with a 24” motorized lift. This lift consists of a telescoping cage which is raised or lowered by four lifting screws. The torque is transmitted through self-lubricating side plates located on each corner of the telescoping cage.

Semi-automatic or fully automatic controls are available as accessories to the lifting device. The semi-automatic control raises the lift at a predetermined torque level and is lowered with a manual pushbutton control. The fully automatic control both raises and lowers the lift at predetermined torque levels.

A lift position transmitter is also available as an accessory on motorized lift. This item senses the elevation of the rake arms, transmitting a signal to a remote recorder or control panel for monitoring.

RAKE ARMS

The rake arms are fabricated steel, either single member structural or a box-truss configuration with welded rake blades for scraping. Cone or trough scrapers are supplied to scrape the discharge cone or trough. Standard rotation is in a clockwise direction. The rakes are powered by a pipe shaft in Type B machines, or by a square cage in Type C mechanisms.

Two short arms or two stub arms are available as auxiliaries to the standard two long rake arms.
