What we offer

Low maintenance, low energy use, 2-base Friction Drive Rotary Kiln

Everything’s visible – for easy inspection, maintenance

The innovative suspension design of our Friction Drive Rotary Kiln means it can offer optimal mechanical reliability compared with traditional rotary kilns. And when it’s time to inspect or maintain the kiln, there are no hidden parts. Everything is visible, for easy inspection and maintenance.

And the kiln alignment isn’t affected by the settling of the foundation, which means you don’t have to worry about periodical kiln axis realignment.

The lack of a kiln girth gear and the low number of supporting rollers help keep your maintenance costs low.

Automatic thrust device keeps kiln in position

Our High Friction Rotary Kiln is kept in position by an automatic hydraulic thrust device (HTD) that controls the axial motion of the kiln. Our HTD can take up the full axial load of the kiln, meaning that roller skewing is not required to take up axial forces.

Reliable seals for high thermal efficiency

A rotary kiln is only as efficient as the seals on its inlet and outlet zones. After all, if false air enters the kiln system, fuel consumption goes up, production output goes down and operating expenses skyrocket.

The High Friction Rotary Kiln graphite seals use a staggered arrangement. Two rows of graphite blocks are held in place with a wire rope system. This means a good, tight seal against the outer air casing.

Take note: The relatively slow speed at the kiln inlet cuts down on dust circulation. That means less kilocalorie consumption and easier operations.

Key benefits

Friction Drive Rotary Kiln: longer life and reduced operating costs

Two-base design saves on space, costs: With only two bases, our Friction Drive Rotary Kiln offers low civil investment costs, low operating costs and never needs realignment.
All parts are visible: Because it has fewer parts than other rotary kilns and all of them are visible, maintenance costs are lower than on more complex rotary kiln solutions.
Lowest heat consumption in its class: Our Friction Drive Rotary Kiln saves your business on energy too: it has the lowest specific heat loss and energy consumption in its class.
Designed for long life: Its low kiln-shell ovality and long brick-lining lifetime means it can offer exceptional durability.

Features

Low-maintenance Friction Rotary Kiln

Self-aligning roller support system

Our Friction Drive Rotary Kiln installations feature direct electro-mechanical drive-through rollers, as well as a fully self-aligning roller support system. The roller suspension maintains constant contact with the supporting rollers. This ensures the efficient transmission of torque and cuts down on the stress that causes pitting and cracks.

No lubrication required between tyre and kiln

Kiln rotation is driven by friction between the rotating support rollers and the kiln tyre. At the same time, a redesigned tyre attachment system allows the kiln shell to expand radially, which means there’s no need for lubrication between the tyre and kiln.

Periodical realignment not required

Because there’s no kiln girth gear and only two supports, maintenance costs are low. And kiln axis alignment is not affected by settling of the foundation, so there’s no need to worry about periodical kiln axis realignment.

Seals require no greasing

Graphite seals at the inlet and the outlet of the kiln reduce false air intake, but they’re flexible enough to follow the kiln’s movements. These seals require no greasing and are practically maintenance-free.
