Presenting serious dangers to both humans and the environment, sludge — the residual semisolids left over from industrial wastewater and energy production — must be dealt with safely and efficiently. Sludge handling allows for cost-effective disposal, allowing many of the discarded resources to be recycled.
Some of the most common sludge removal methods include:
- Centrifugation — The separating of liquids by material density; heat is used to evaporate water and reduce moisture content of materials through conduction, convection, or radiation
- Direct drying — Removing moisture from the material via evaporation, which is brought about when the material comes into contact with hot gases; this method involves the use of rotary dryers or fluidized bed dryers
- Indirect drying — Removing moisture from the material through contact with a heated metal surface; this is achieved via paddle, disc, or hollow flight dryers
Cranes and Hoist Systems for Sludge Handling
Employing high-quality, reliable biomass cranes and hoists will help ensure safe and efficient sludge handling while keeping down costs. Specifically designed for handling waste, garbage, sludge, and other hazardous materials across a wide range of industries, these hoists and lifts are especially important in the waste-to-energy industry.
Below are some of the most common types of biomass cranes:
- Automatic waste handling cranes — Designed for continuous operation and controlled via a monitor in a central control room, these units generally have a capacity ranging from 3.2 to 10 tons, and can lift to heights of 15 meters or more over a span of 7.5 to 25.5 meters. Automatic waste handling cranes are used for a wide range of activities, such as mixing, stacking, handling, and stirring of waste in incinerators.
- Slag handling cranes — Slag handling cranes are used to continuously distribute slag under combustion lines to other areas of the slag bunker. Also employed to load slag onto trucks, these cranes can lift 5 to 10 tons over a span of 7.5 to 10.5 meters.
- Biomass handling cranes — Crafted with optimal versatility in mind, these compact cranes offer excellent performance and reliability, with lifting capacities up to 20 tons and the ability to span up to 28 meters.
- Sludge handling cranes — Built specifically to help transfer semi-fluid sludge from trucks into storage and through the process line, these cranes are designed to withstand harsh sludge handling station environments — which typically involve extremely sticky materials. Sludge handling cranes can lift between 5 and 16 tons, with a span of up to 16.5 meters.
- Straw bale handling cranes — Used for unloading and feeding straw bales from trucks, these cranes are built to withstand dusty, high-humidity environments and can perform continuously with ease. Able to handle 10 to 20 tons, straw bale handling cranes span 15 to 31.5 meters.
