Advantages of coal slime dryer

downstream drying fully realizes heat exchange and heat conversion, improves drying efficiency and heat utilization, reduces exhaust gas temperature and exhaust dust emission concentration, and ensures energy saving, emission reduction and environmental protection. The system can be used for mechanized drying of large quantities of coal slime, controlled by an intelligent automation system, and the drying capacity is 300~2000T/D; the moisture content can be reduced from 30±5% to 12±2%; the low calorific value of the coal slime Can increase 1000- 1500Kcal. The diameter of the drying drum ranges from Φ 1.9 meters to Φ 3.4 meters, and the length ranges from 15 meters to 30 meters.

Coal Slime Dryer System

Dongding coal slime dryer system is mainly composed of the following six parts.
⑴ Raw material loading system: including break-up feeder, feeding belt conveyor, etc., to ensure uniform and continuous feeding.
⑵ Combustion heating system: including high-efficiency boiling furnace, automatic chain gate furnace, pulverized coal injection furnace and other high-efficiency hot air systems, to ensure that a stable high-temperature heat medium is provided to the drying system.
⑶ Drying and dewatering system: select sealed feeding box, screw propeller, drum dryer, discharge box and other equipment to complete the mass and heat exchange between high-moisture materials and high-temperature heat medium.
⑷ Exhaust airflow system: Cyclone dust collector, bag filter, induced draft fan and other equipment are selected to send the exhaust gas into the centralized dust removal system after preliminary treatment.
⑸ Power distribution measurement and control system: select complete sets of power distribution devices, on-site boxes, temperature control sensors and other electrical equipment to realize the control and monitoring of the drying system.
⑹ Product conveying system: belt conveyor is used to conveying the dried product to the location designated by the user.
