Screw sand washers are among the most widely used equipment in quartz sand washing and classification. They separate quartz sand from clay, slime, and light impurities through the agitation and conveying action of spiral blades. However, in practical selection, many users easily fall into misconceptions—either believing "bigger is better" or focusing solely on price. This […]

A rotary drum dryer is a continuous industrial drying machine used to reduce the moisture content of bulk materials. It is commonly applied to sand, minerals, coal, clay, fertilizer, biomass, sludge, chemicals, and other materials that require stable and large-scale drying. Compared with small batch drying equipment, an industrial rotary dryer can handle larger production […]

Choosing a rotary drum dryer for sawdust is not merely about purchasing a machine; it involves tailoring a drying system to your specific raw materials, site conditions, and budget. This choice determines whether your sawdust transforms into high-value fuel pellets or remains mere waste. Choosing a dryer requires balancing heat, airflow, material retention time, and […]

A rotary drum dryer for kaolin drying is essential equipment for dewatering kaolin clay in industries such as ceramics, papermaking, and coatings. When selecting this type of equipment, factors such as kaolin's high moisture content and its tendency to shrink and deform when heated must be considered to match the appropriate drum size, heat source […]

Selecting a rotary drum dryer for coal drying involves more than confirming the required hourly capacity. Coal type, particle size, moisture content, heat source and operating conditions all affect the final equipment configuration. At Staurk, we select the dryer according to the actual material and production requirements. The goal is to achieve stable final moisture, […]

What Is a Rotary Kiln? A rotary kiln is an inclined, constant-speed rotating calcination and roasting equipment used widely across various heavy industries for high-temperature processing. It is a highly complex thermal system subjected to mechanical stress, thermal deformation, and chemical corrosion. Driven by the constant rotation and natural gravity of the kiln, raw materials […]
