First, the nature and use of lignite:
Lignite dryer Raw lignite drying brown and even dark brown. The brown coal in accordance with the hardness can be divided into hard and soft brown coal lignite, according to the surface gloss can be divided into dark and light brown coal lignite. In general, the geology than bituminous coal lignite formation stage Short correspondingly lower carbon Zhengzhou Jinyang Machinery Co., Ltd. expert conclusion on the chemical composition is the same chemical elements in lignite and bituminous coal, but in different proportions of the number of elements. First, the lignite containing carbon than bituminous coal in less than bituminous coal and oxygen in much. lignite oxygen are used to form the majority of humic acid, which is the youngest lignite characterized by further carbonization, humic acid become humins according to different origin, former lignite It may contain 15 to 60% water, and mineral content can vary between 3-20% (dry basis) of a broad range of raw lignite many water heat Pavilion 1 million joules / kg, anhydrous and the calorific value of lignite ash-free between 20000-3 million joules / kg. Thus, the low calorific value of lignite school bituminous coal.
After drying lignite lignite drying machine has many uses, for example, is used as a reducing agent and metallic minerals used as chemical raw materials.
Second, the lignite dryer (dryer) Features:
Jinyang quality lignite rotary dryer, also commonly used in the slime drying, dried lignite in ensuring the quality of the same circumstances, the use of low-temperature four drying process, the lignite water evaporation to below 13% moisture content. Primary bake dry area in the state at 400 ℃ high temperature and high humidity to remove most of the water to ensure that the chemical composition of lignite does not change and difficult to fire; secondary drying zone temperature 300 ℃, temperature strength by the wind high yield in addition to water, to ensure lignite no coking ; three indoor temperature drying zone 120 ℃ -210 ℃, use the crushing device in the drum, repeated impact, broken material, downstream drying; four exhaust zone drying zone is high, room temperature 60 ℃ -80 ℃ , cited by the negative pressure air system low temperature hot air exclude moisture.
These are the Zhengzhou Jinyang Machinery Co. summary Lignite dryer Some notable features, more details we welcome you to contact us directly to us, we are confident to provide you with the best domestic lignite dryer equipment.
Third, the lignite dryer market outlook:
Jinyang lignite dryer with the rational development of the implementation of the sustainable development strategy, coal and other mineral resources and utilization has become an important issue, originally as a waste of idle stacked slime fully exploited has become essential. Use of valuable slime resources, so that turning waste into wealth, not only can produce considerable economic benefits, but also to solve a series of problems slime piled occupation of land and pollute the environment. The most effective method is to slime dewatering, sludge dryer use Jinyang next, the raw lignite dryer wet slurry dehydration, can be dried in ensuring coal, lignite quality of the same premise, the slime dewatering to a moisture content below 13%, improve combustion efficiency, making more full use of coal resources.
