Limestone is a sedimentary rock with many agricultural and industrial purposes. In order to prepare this naturally occurring mineral for use as a filler, fertilizer, or building material, many manufacturers utilize a drying step during limestone processing. The most commonly used equipment for limestone drying is a rotary dryer. It can be used to dry both limestone ore and pelletized limestone. Also referred to as a limestone dryer, this piece of equipment is popular for use in many processing stages, because it is a reliable drying solution. The high volume functionality and robust build of a limestone dryer can easily withstand limestone’s processing demands. With the increasing demands of construction aggregate, Hongxing high frequency vibrating screen, limestone rod mill has made an rapidly growth in technology, and has made great contribution to development of many mines in the world.

Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is...
