Product Description
This 500 tons per day coal drying system is a medium-sized integrated industrial drying unit tailored for mid-scale coal processing sites. It stably processes 500 tons of raw coal, coal slime, lignite or granular coal per day, reducing the final moisture of finished coal to below 12%, effectively boosting coal calorific value and lowering subsequent transportation and storage costs. It supports 16-20 hours of continuous daily operation, and can be seamlessly connected with upstream and downstream equipment to form a fully automated production line.
Working Principle
Powered by a heavy-duty transmission assembly, the inclined rotary drum runs at a precisely calibrated low speed. Wet coal is evenly fed into the drum, repeatedly lifted, turned and scattered by optimized cascading lifting flights to form a uniform full-section material curtain, which fully contacts with counter-flow high-temperature flue gas for sufficient heat and mass exchange. The moisture in coal is rapidly evaporated, the generated water vapor is purified by the multi-stage dust removal system and discharged up to standard, and the dried qualified coal is continuously output from the discharge end. The built-in automatic anti-blocking cleaning device runs synchronously with the drum, eliminating the sticking and clogging problem of high-viscosity coal.
Key Features
500 tons per day rated processing capacity, perfectly matching mid-scale coal plants' daily production demand
High-efficiency thermal circulation structure, thermal efficiency over 90%
PLC automatic temperature control system, easy to operate with only 2-3 operators for the whole line
Multi-stage environmental protection dust removal configuration, meeting strict industrial emission standards
Stable 24-hour intermittent operation, low maintenance cost and long service life
