Challenges in Limestone Processing

Limestone Processing Issues: Abrasive and Prone to Clumping

A drying process is often used to precondition limestone rock for subsequent manufacturing steps. Like most rocks, limestone is abrasive as a raw material. As a result, heavy duty rotary dryersare recommended to handle limestones abrasive characteristics. Drying processes may also be used on powdered limestone, with the recommended equipment again being rotary dryers. Many limestone manufacturers address moisture issues and prevent material clumping by utilizing a drying process before stori...

Limestone Processing Issue: Emission Control

Rotary kilns are most often used to produce lime products in the United States. Hot combustion gases and limestone move counter currently within the refractory lined drum of the rotary kiln, applying a high temperature process that ultimately changes the raw material into a high calcium lime or dolomitic lime. Particle matter pollutants are a common issue with rotary kilns, requiring the application of a particulate control system in order to counteract this problem. FEECO also offers special...

Limestone Processing Issue: Moisture

Pelletization resolves a number of issues associated with limestone processing, from uniformity to nutrient delivery. Limestone pelletsoffer reduced dust, more accurate application, improved handling, and less product lost to dust. Fortunately, with such great benefits, limestone pelletization is a fairly straight forward process. However, there are still limestone processing problems that must be considered. For example, moisture is an important element in effectively pelletizing limestone....

Limestone processing problems are not unlike the challenges faced by many other naturally occurring materials. In addition to build up and clumping problems, limestone composition can also vary from one region to another.
