As we all know, the dry processing of ball mill is an useful way to crush materials. What are the advantages of dry processing? This article will give you a brief introduction.
There are many advantages in upgrading coal with dry jigging technology. The most obvious is the lack of process water, which eliminates the need for fines dewatering and slurry confinement. Dry jigging eliminates the clean coal moisture penalty associated with wet processing. Particulate emissions are virtually nonexistent due to inclusions of fabric dust collectors on all modern dry jig plants. Because of the environmentally friendly nature of dry jig plants, installation permits are often measured in days, not months. There has also been a fundamental advance in dry jigging efficiency. All of these advantages have renewed the coal industry’s interest in dry jigging. But air jigging is not right for every application. There are limitations due to particle size, particle shape, moisture and near gravity content. This article explores the evolution of dry jigging. It reviews parameters important for determining the suitability of dry jigging. It also compares historical performance data as measured by imperfection, against results from modern dry jigging technology. The article also presents data from modern dry jig installations.
Whether coal is upgraded by wet or dry technology, the reduction in ash, sulfur, mercury and other mineral contaminants, while increasing the calorific value, benefit the cleanliness, efficiency and operating costs of coal users. This includes power plants, coke operations and sponge iron plants. Consuming high-ash and high-sulfur coal in the production of power contributes to pulverizer wear, boiler tube wear, slagging and fouling and loss of generation capacity. Poor quality coal produces unacceptable coke. At sponge iron plants, it decreases yield. Dry beneficiation of coal offers a number of advantages. Governments all over the world are continuing to place more stringent limits on the release of pollutants from coal cleaning plants. Air jigging has an inherent advantage since it uses no process water. Also, modern air jig plants are supplied with fabric dust collectors that eliminate dust as a pollutant. Therefore, one of the principal advantages of the modern air jig plant is environmental friendliness. Dry cleaning does not introduce a moisture penalty to the clean coal product. This advantage is particularly important if the amount of improvement needed is minimal. The processing cost for upgrading coal with dry technology is often low and further enhanced by the elimination of improvement in separating efficiency. Their coal can be upgraded, dry, without a severe penalty in yield.
