Limestone dryers are widely used in building materials, metallurgy, mineral processing, chemical, cement and other industries.
Limestone is a sedimentary rock with many industrial uses and it has a relatively high humidity. Whether in the mining stage or in the processing stage, dry limestone has many benefits and plays a vital role in the production of high-quality limestone products. Before being used in the industrial field, it usually needs to be dried before it can be used in the appropriate industrial field.
FTM dryers can support multiple heat sources and are easy to switch. The choice of heat source determines the operating cost of the equipment, so the choice of heat source needs to consider safety, environmental protection, material quality requirements, etc. The more common heat sources are mainly divided into three categories: solid fuel, gas fuel, and liquid fuel.
The thermal efficiency is 80% to 90%. The new internal structure strengthens heat conduction of dispersed materials, and eliminates the sticking phenomenon of the inner wall of the cylinder.
Since the heating mode is easy to control, the temperature inside the cylinder and the heat transfer rate of the partition wall can be kept relatively stable.
The cylinder of the dryer is made of steel material, which has the characteristics of high hardness and high toughness.
The dryer system has good sealing performance, and is equipped with a complete dust removal device, with little dust spillage and a good operating environment.
