Then China KJG series sewage sludge paddle dryer from DOINGMACHINE is exactly what you need if you are shopping for a powerful and dependable solution for drying sewage sludge. This effective device was designed to manage big volumes of waste products, reducing moisture content and making a top-quality end item.

It comes with a high-speed agitator that guarantees uniform mixing through the entire drying method. This assists in order to avoid the forming of lumps or clumps which could cause uneven drying. The agitator additionally helps lessen the number of power needed, since it helps circulate temperature evenly through the product.

The device was manufactured having a double-pipe framework making certain the heating medium remains split through this product while being dried up. You can stop contamination and helps to ensure that your end item satisfies the greatest criteria of purity. The unit can be loaded with an automated cleansing, enabling you to clean and sanitize the product quickly between batches.

The China KJG series sewage sludge paddle dryer is the perfect solution for you if you are working together with municipal sewage sludge, commercial waste or agricultural by products. This revolutionary product was created for the most challenging drying jobs with simplicity along with its high-capacity design and high-efficiency home heating. Plus, its lightweight size and easy-to-use settings allow it to be a fantastic choice for almost any commercial environment.

Product Description

Main features:

1. Continuously drying of sewage sludge, animal manures and industrial sludges;
2. Heating area: 10-200 M2
3. Evaporation capacity: 60-2000 kg/h
4. Vapor tight or vacuum designs are available
5. Heat source: steam, hot water or hot thermal oil

Working Principle:

KJG series Paddle Dryer / Processor are highly efficient, mechanically agitated, indirect heat transfer devices that add or remove heat from a process mass. It's commonly used for drying, heating or cooling of paste, filter cake, powder and granule materials from various industries.

Paddle dryer consists of a jacketed trough and two counter-rotating shafts with unique intermeshing hollow discs to produce intimate mixing and optimize heat transfer. Heat medium, such as steam, hot water or hot thermal oil, flows inside both the heating jacket and hollow discs to form heating surface. Wet material is conveyed through the paddle dryer by agitator paddles welded on disc peripheries. With regular mixing, shearing, displacement and heat transfer, moisture evaporates fast and uniformly. When wet material reaches the opposite end of the dryer, it's dried and discharged directly.

Evaporated moisture is sucked out by draft fan after being treated by cyclone, condenser and wet scrubber to considerably reduce air contamination.

Technical advantages

1) High thermal efficiency which can reach 95%

2) Heat transfer medium does not contact the product.

3) Gas is not used to convey the product. Off-gas flow is minimal.

4) Precise control of temperature

5) Uniform product quality, through mixing and movement of the product

6) Continuous process on a once-through basis

7) High heat transfer area to process volume ratio - reduced floor space

8) Easy to operate, requires minimal attention

9) Safer than direct drying when processing combustible material

10) Simple durable design for easy and low maintenance

11) Dual counter-rotating shafts with unique intermeshing discs produce intimate mixing, uniform heat transfer, a high heat transfer rate, and a self-cleaning effect.A large heat transfer area to volume ratio is achieved by the use of hollow discs and a jacketed vessel, through which the heating medium flows. The result is a compact machine with less space requirements and lower installation cost.

12) Paddle Dryer transports material, regardless of its handling characteristics. Sticky, pasty materials can be transported. Pre-conditioning the feed by mixing with recycled dried product, to make it conveyable, is not required. This results in lower capital, operating, and maintenance cost.

Tubular heating jacket

1) Working pressure as high as 10 bars

2) Tubular heating jacket ensure very uniform heating and precise temperature control

3) Full-length vapor dome reduces carry-over and separates solids from the evaporated water vapor.

3) 80mm mineral insulation considerably reduces heat loss

Hollow disc

1) Considerably increase heating surface

2) Much less welding area than wedge shape paddles

3) Self-cleaning disc surface considerably enhances heat transfer
4) Agitator paddles welded on disc peripheries with different angles perfectly mix, move and crush wet material

FAQ

Q: What information should be provided in order to get a proposal or quotation?

A: Our paddle dryer is specially designed for each customer according to specific wet material, capacity, drying temperature and heat mediums. Before we can work out a detailed proposal, we have to know the following information:

1) Detailed information of wet material you are going to dry. We may ask you to provide composition report or samples for drying test.

2) Type of moisture.

3) Initial moisture content before drying

4) Required moisture content in dried product

5) Drying capacity in kg/h

6) Heat medium to be used for drying. Such as steam, thermal oil or hot water

Q: How the machine is delivered ?

A: Paddle dryer is very heavy and its weight ranges from 3 tons to 50 tons. When the heating area is less than 120 M2, the dryer body can be shipped by 40 feet HQ container; 120-150 M2 should be shipped by 40 feet OT container; more than 150 M2, the dryer body has to be dismantled for shipping.

Q: What kind of after sale service you can provide?

A: We have professional after sale service team who can reach you in short notice. They can supervise the installation, do commissioning and train your workers.
