(2) The belt dryer is not only for material drying, but also sometimes for material baking, firing or maturing operation.
(3) The structure of the belt dryer is not complicated, easy to install, and can run for a long time, and it can be accessed to the inside of the box body for overhauling in case of failure, so it is convenient for maintenance. (1) Single-stage belt dryer: the material to be dried is evenly distributed to the conveyor belt from the feeding end through the feeding device. The conveyor belt is usually made of perforated stainless steel sheet, driven by the motor through the gearbox, which can be speed-regulated. The dryer box is usually separated into several units in order to control the operating parameters independently and optimize the operation. There is an isolated section between the drying sections where no drying medium circulates.
(2) multi-stage belt dryer: multi-stage belt drying is essentially composed of several single-stage belt dryer in series, the principle of operation is the same as single-stage belt dryer.
(3) multi-layer belt dryer: multi-layer belt dryer is commonly used in drying speed requirements for low, long drying time, in the whole drying process process operating conditions can be maintained constant occasions. Set up between the layers of the partition to organize the drying medium of the directional flow, so that the material drying uniform. Multi-layer belt dryer occupies less space, simple structure, widely used in drying grain materials. However, due to the operation of multiple loading and unloading, so it is not suitable for drying materials that are easy to stick to the conveyor belt and do not allow crumbling.
(4) impact belt dryer: impact belt dryer is suitable for drying fabrics, tobacco, substrate surface coating and other flaky materials. Impact belt machine usually consists of two conveyor belts. The impact belt machine can be separated into unit sections for independent control. Drying medium humidification, part of the discharge, the other part of the return to the fresh drying medium mixed into the cycle again.
