Rotary Dryer

Product Description

Rotary dryer, also known as rotary drum dryer,rotary drier.High humidity material dryer is a kind of drying equipment, which is developed by Henan Hongke company to meet the needs of the market. The whole set of dryer be composed offeeding part, drying part, heat source part, discharging part and waste gas treatment part. Raw material with 75% mositure can be dried, such as sludge, mud, animal manure, slag, etc. According to different ways of heating raw material,the rotary dryer can be divided into direct heating-type rotary dryer and indirect heating-type rotary dryer. The rotary dryer can be classified into Coal Slime Rotary Dryer, Sawdust Dryer, Coconut shell dryer,  slag rotary dryer and clay rotary dryer according to different raw materials.According to different structure, the rotary dryer can be divided into Three cylinder dryer, Double-drum Dryer. Being widely used in building materials, metallurgy, chemicals, industrial drying slag cement limestone, coal, slag, clay and other materials. The aircraft is mainly composed of the rotary, jan plate, transmission, seals, and other support equipment and components. Being featured with a reasonable structure, well-produced, high yield, low consumption and operating convenience. Offering products quality assurance, and highest free installation debugging agent can be checked with other plants than quality and prices.

Feature

Wheeled cement kiln (cement kiln) for preparing dry and wet clinker.

Rotary Kiln (Mining Chemistry): Magnetization and Oxidation of Roasted Iron Ore in Steel Plants

Wheel kilns use high-strength aluminum ore for roasting in plant smelting.

Rotary kilns used in aluminum alloy barbecue factories, chrome plated barbecue factories in chemical factories, and powder factories.

Rotary kilns (lime kilns) are used for active calcification of lime and dolomite in steel and ferroalloy plants.

Working principle

The dry wet material is transported to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipeline through the feeding machine of the hopper. The slope of the feeding pipeline should be greater than the natural inclination angle of the material, so that the material can flow smoothly into the dryer. The cylinder of a sleeve dryer is a rotating cylinder that is slightly inclined to the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, forming a countercurrent contact with the material. There are also heat carriers and materials flowing together into the cylinder. As the cylinder rotates, the material moves to the lower end under the action of gravity. During the forward movement of the wet material in the cylinder, it directly or indirectly receives heat from the heat carrier, allowing the wet material to dry and then be sent out through a belt conveyor or screw conveyor at the discharge end. There is a board installed on the inner wall of the cylinder, which is used to pick up and scatter the material, increasing the contact surface between the material and the airflow, in order to increase the drying rate and promote the material to move forward. Heat carriers are generally divided into hot air, flue gas, etc. After the heat carrier passes through a rotary drum dryer, a cyclone dust collector is generally required to capture the materials carried in the gas. If it is necessary to further reduce the dust content of exhaust gas, it should also be discharged after passing through a bag filter or wet dust collector.
