After being disposed by biodiesel sludge dryer, the sludge can be dried to dry mud with 90% solid content. Our sludge dryer adopts advanced dehumidifying heat pump technology and can save over 40% energy. About 0.25-kw/h electricity is consumed to split one-ton water from sludge. It can adopt peak electricity mode, which can save energy over 60%.
Rotary Kiln Temperature Control. Rotary kilns (or rotary dryers) are used extensively in industry for drying solids. They consist basically of a large metal tube which is rotated while hot air and wet solids are fed into it. Both co-current and counter-current configurations are used. Below is a schematic of a typical dryer used to dry polymer ...

Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to the category of building materials equipment.Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials.Cement kilns are mainly used for calcining cement clinker.There are two kinds of kilns: dry production and wet production.
The K-S Paddle Sludge Dryer provides a reliable and efficient method for drying filter cakes and centrifuge concentrates. The K-S Paddle Sludge Dryer is indirectly heated using steam or circulated thermal fluid (hot oil). High-energy efficiencies and low off-gas volumes are characteristics of a K-S Drying …
Rotary kilns (also known as rotary calciners) are used to heat solids to a predetermined temperature in order to create a chemical and/or physical reaction.The two basic types of rotary kilns – direct fired and indirect fired (calciners) – can be found supporting processes in mineral, agriculture, and other material processing industries.
At present mainly in the rotary kiln production of lightweight aggregate, kiln outside into ball and kiln into spheres of the two process routes. Outside the kiln balling is using a ball on disc granulation equipment, the first raw material of a certain size globular state, and then into the rotary kiln roasting.
The composition of lime mud varies from mill to mill depending on many factors: wood species, the impurities in the make-up lime and refractory bricks used in the kiln, the efficiencies of slakers, causticizers, clarifiers and mud washers, and the burning conditions in the kiln. On a dry basis, lime mud typically contains about 95 wt% CaCO3
The equipment required is incineration rotary kiln. The incineration rotary kiln has the basic characteristics of non-polluting and low energy consumption in the incineration process. It is the exclusive equipment for treating waste.This article will provide a detailed introduction to the equipment for incineration rotary kiln.

During the first three to four burns when the bricks and the earth floor are drying out, the kiln is considered "green" or "immature" and the yields are somewhat lower. The useful life is five years at least and no special maintenance is needed. Whenever small cracks appear on the walls, small pieces of brick and mud are used to close them.
Cement Rotary Kiln Description: Rotary kiln can be divided into Cement Kiln, Metallurgical Chemical Kiln, Lime Kiln, Ceramsite Kiln, Zinc Oxide Kiln, etc.The cement rotary kiln is mainly used for calcining cement clinker, dry process to produce cement kiln and the wet process to produce cement kiln; the metallurgical chemical kiln is mainly used for magnetization roasting of iron ore mine in ...
wet process, the mixture is a mud that is fed into the kiln with approximately 30-40% of moisture (Saidur et al. 2011, Del Coz Díaz et al. 2002). This paper considers the dry clinker production, which is the most used process in Brazilian production of cement (Kihara and Visedo 2014). A rotary kiln in a dry …
