Rotary joints provide a reliable seal between fixed piping and rotating components whether it is with steam water thermal oil or any other fluid we have found that many rotary joint installations have deficiencies that lead to premature operating life and an increase in maintenance frequency deviation from recommended practices can have significant negative impact on equipment

Direct heat dryers where the heat transfer occurs by convection of hot air or gas inside a rotary cylinder are the most common and used thermal dryers hot air or gas flows through the cylinder and then transfers to the product warming it and evaporating the water therefore temperature of heating media inside the dryer is the mean parameter

The directly heated rotary dryer operates on the principle of lifting and showering the product through a hot gas stream moving either in parallel or counterflow whereas with the indirect dryer which is more suited to fine and dusty materials there is little or no contact between the product and the drying gases since they are heated from the outside via a stationary jacket fitted with

Rotary dryers that require a tightly controlled atmosphere are best served by the indirect configuration indirect dryers avoid contact between the material and the products of combustion by heating the dryer shell from the outside via an enclosed heat shroud or furnace

Rotary dryer a rotary dryer can be used however the generation of fines is high these are vey low rpm dryers and hence the drying is inconsistent ie the dried coal does not have uniform moisture tornesh or flash dryer maximum particle size limited to 6 mm though dryers are cheap the crushing of coal to lower sizes cannot be avoided
