Continuous disc dryer plate dryer for lithium carbonate

PLG Series Continuous Plate Dryer is also called disc dryer, it is a high-efficiency conducting and continuous Drying Equipment. Its unique structure and operating principle determine that it has advantages of high heat efficiency, low energy consumption, small occupied area, simple configuration, easy operation, and control as well as good operating environment and etc. It can be widely used in the drying processes in the fields of chemical, pharmaceuticals, agricultural, foodstuff, feed, and other industries for drying powder and granules materials.

2. Working principle of disc dryer:

The working principle of plate dryer is: The wet material is fed continuously to the first drying layer on the top of the dryer. It will be turned and stirred by rakes when the rake arm rotates and drop down to the outer edge of the large drying plate along the exponential helical line.
The material will be moved from the small drying plate to its outer edge and dropped down to the outer edge of the large drying plate underneath. Both small and large drying plates are arranged alternately so the materials can go through the dryer continuously.
The heat medium can be saturated steam, hot water, or thermal oil. The heat will be led into hollow drying plates from one end and come out from the other end.
The dried materials will drop from the last layer of the drying plate to the bottom of the dryer and then move by rakes to the discharge outlet.
The material moisture will be removed from the exhaust outlet on the top cover. For the vacuum-type plate dryer, the moisture will be sucked out by the vacuum pump on the top cover.
The dried materials will be discharged from the bottom layer. The drying capability can be improved if the dryer is equipped with supplementary devices such as a finned heater, condenser for solvent retrieval, bag dust remover, return and mix mechanism, exhaust fan, and etc.

Plate dryer has the following features:

1. Easy to control, and wide application

5. Easy installation and small occupying area.
