Material feasibility check

FLSmidth laboratories offer testing of your materials in a pilot plant to evaluate the feasibility of processing in a dryer crusher and the subsequent service life expectancy of the hammers.

How it works

The FLSmidth Dryer Crusher is specially designed to handle soft and sticky, low-abrasive raw materials such as chalk, clay and slurry.

It’s built to expertly handle very high temperatures of 400°C to 800°C, crushing and drying in a single operation.

As the raw material passes through the hammers, coarser grains fall back for further pulverisation, and the water content of the raw material is reduced to approximately 1%.

Specs

• Hammer lip speed spans 26 to 33 m/s depending on the material and process
• Outlet temperature between 130°C and 150°C
• Hammer service life can exceed a full year and hammers can be replaced without dismantling the hammer rotor
• Heat from the kiln preheater exit gas is recycled for drying

Maintenance

Gear, auxiliary drive couplings and lubrication unit are mounted on a common base frame facilitating easy erection and maintenance.

The straightforward construction houses no elaborate parts, thereby increasing hammer mill drier reliability, simplifying servicing and reducing maintenance costs.

Hammers can be replaced without dismantling the hammer rotor.
