The rotary dryer works by minimizing the liquid moisture content of the material it is handling. The dryer consists of a large, rotating cylindrical tube, supported by concrete columns or steel beams. The slope of the dryer ensures that the discharge end is lower than the material feed end, gravity then conveys the material through the dryer, towards the discharge end.
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 reaches the top of the dryer, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. The gas stream can either flow co-currently with the material, from the feed end towards the discharge end, or counter-currently towards the feed end from the discharge end.
The gas stream can be a mixture of air and combustion gases from a burner, in which case the dryer is known as a direct-heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) preheated gas, in which case known as an indirect-heated type.
Henan Zhangsheng's new rotary dryer is available in both direct and indirect heating configurations, making it an ideal choice for various industries. Indirect-heated dryers are often used when product contamination is a concern, while direct-heated dryers are ideal for heat-sensitive materials.
The company's rotary dryer is also designed to be energy-efficient, with low operating costs and reduced emissions. The dryer's advanced control system ensures precise temperature control, allowing for optimum drying conditions, and energy savings.
In addition to the rotary dryer, Henan Zhangsheng offers a wide range of biomass pellet equipment, including wood pellet lines, wood chippers, sawdust crushers, horizontal grinders, and biomass pellet machines. The company's equipment is renowned for its durability and reliability, making it the preferred choice for many industries.
Established in 2010, Henan Zhangsheng Environmental Protection Equipment Co., Ltd. is a leading manufacturer of pellet equipment and other environmental protection machinery. The company has a strong commitment to quality and innovation, with a team of experienced engineers and technicians dedicated to developing new and improved products.
The company's rotary dryer is expected to be a game-changer in the industry, providing superior drying performance and efficiency, while reducing the environmental impact of industrial processes. With its advanced features and energy-saving benefits, the new rotary dryer is sure to become a popular choice for many industries, including agriculture, animal husbandry, and forestry.
