What are the technical parameters of a drum dryer

The main body of a drum dryer is a cylinder, and the larger the model, the larger the diameter and length of the cylinder. Large drying machines have a cylinder diameter of over 3 meters, a cylinder volume of 141.3-285m ³, a production capacity of 30-76 tons, an intake temperature of 7-8 degrees Celsius, and an equipment weight of 85-135 tons. In order to drive such heavy equipment, the power of the main motor of the equipment is 75-160kw.

What is the working principle of a drum dryer

The heat source of the drum dryer comes from the combustion device and adopts a downstream heating method. Therefore, the materials that need to be dried are pushed back by the spiral cutting plate from the feeding box and the feeding chute into the cylinder. Due to the inclined placement of the dryer, on one hand, the material flows towards the rear under the action of gravity and rotation, and on the other hand, the material is repeatedly picked up by the copying board, carried to the upper end and continuously sprinkled down, forming a uniform curtain inside the cylinder, fully exchanging heat with the hot air flow inside the cylinder. As the material is repeatedly sprinkled, the moisture contained is gradually dried, thus achieving the purpose of drying.

What is the difference between a drum dryer and a roller dryer

Drum dryers, also known as roller dryers, are a type of dryer that was developed in the early 1900s. They were utilized for drying liquid materials, heavy liquids, pastes, and solid solutions or suspensions, in the agriculture, food, and chemical industries before spray dryers were developed.

What are the suitable materials for drum dryers

Drum dryer, used to dry wet materials with anti pollution requirements. Suitable for drying chemical products, powders, straw, shavings, wood chips, and mixed coal materials. It has the advantages of high drying capacity, smooth operation, low energy consumption, convenient operation, and high output.
