Introduction

Lignite dryer has two 'high' and three 'low' properties: high moisture (water content is generally between 32% and 42%), high volatile (generally between 40 to 50%), low heat (average calorific value is about 3,000 kcal), low density and low ash melting point. Fote Machinery is a professional manufacturer of brown coal dryer in China, which is applied with scientific and advanced technology to remove water, which has enhanced the economic value of lignite and promoted the conservation and development of brown coal resources. The main components of lignite drying machine are: shredders, conveyors, feeders, heating equipment, rotary dryer, feeder, wind system, dust removal equipment, temperature control equipment, electrical systems, etc.

2. Maximum production safety.

Lignite drying equipment has automated devices which are free from flame and explosion to prevent the occurrence of accidents during its production process. Fote lignite coal dryer has experienced technology experts and on the construction the sites to ensure the stable operation of the equipment .our after-sales services include free warranty for one year and lifetime maintenance to bring customers more benefits.

3. Good quality of finished materials.

The settlement structure of lignite dryer consists of three layers to reduce dust pollution to the materials. High-temperature and rapid process has reduced the loss of organic elements. Online moisture monitoring and fuzzy control contributes to even water contents of materials after drying process.

4. High drying strength.

The water removing amount of lignite dryer has reached up to 8000KG per hour, which can realize uninterrupted production.

5. High drying efficiency.

Lignite drying machine adopts high-temperature and rapid drying process, which makes the utilization of air temperature increase 40 percentage points than ordinary temperature drying methods. Its heating system has up to 90% thermal efficiency, which allows integrated thermal efficiency up to 73 %. After drying process, part of the hot wind is transported from the beginning to the end for continuous heating to reduce heat loss.
