Kiln Load Analysis

With over 80 years of experience and close to 1,000 installations, FLSmidth Minerals is your One Source for rotary kilns and dryers for the minerals industry.

We supply rotary kilns and dryers for processing alumina, bauxite, copper concentrate, lightweight aggregate, lime sludge, limestone and phosphate.

We build quality into every product we make. Kiln and dryer shells are rolled to exacting tolerances, and are sufficiently strong to accept reasonable misalignment, overloads, and thermal stresses. All shop joints are automatically welded. Riding rings are of full-floating design and are machined on all surfaces. The roller supports are the two-roller type, made of either cast or forged steel rollers shrunk onto shafts of medium-carbon forgings. At least one support mechanism in each kiln is normally equipped with a pair of thrust rollers with bearings to prevent the kiln from moving uphill or downhill. Various types of air seals have been devised for both the feed and discharge ends of the rotary kilns or dryers.

We pay particular attention to the design and quality of the main gear. Kilns and dryers are normally driven at speeds between 0.4 and 3.5 RPM. The drive train in this equipment consists of a motor, gear reducer, pinion and main gear, and proper design essential to long drive life and vibration-free power transmission. Our main gear is attached with tangent spring plate mounts which allow expansion or contraction of the shell without affecting gear alignment or "goose necking" the shell. This method of attachment also absorbs vibration and helps create smooth transmission of power.
