The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic, and social factors. The technological factors include, at a minimum, the number of seams, the thickness and steepness of each seam, the nature and thickness of the strata overlying the seams, the quality of the coal seams, the surface topography, the surface features, and the transportation networks available. Economic factors include energy demand and its growth, the supply and cost of alternative sources of energy, coal quality and the cost of coal preparation, the selling price of coal, advancements in technology that affect costs of production, and environmental legislation. Social factors include prior history of mining in the area, ownership patterns, availability of labour, and local or regional government support.
There are four key factors that affect the choice of dryer model: output, feed humidity, feed humidity and material type.
Various prices are available for palm oil processing machines, depending on the raw material, production capacity, process design, equipment quality and manufacturer.

The price of small bag wood pellets in USA market is about 170USD/tonne, while large package is 135USD/tonne. In Sweden it is 150USD/tonne, while the FOB price of bulk wood pellets is 80USD/tonne. Exclude production cost, it is still profitable to establish wood pellet plant.
The velocity of the drying media is effective on the LRC drying. In the literature, the different velocity values are studied. In the fluid bed coal-drying studies, the fluidization velocity is also studied. For the case of the fluid bed drying, the level of the drying media’s velocity according to the minimum fluidization velocity is very important.
The Volcano LIN Target Package (LTP) is a LIN only product providing a resource efficient implementation for LIN nodes according to the LIN 2.0 standard.
Cutting Machine: Cutting machine is the key equipment in the AAC Production line, the working Principle is the tiling hanger turns the mould 90 degrees in the air, open the mould and takes block onto the cutting cart together with the side plate. The cutting car was driven by the motor. The block would be driven for horizontal and vertical cutting. The cutting cart will move to semi-finished product hoister, and the hoister loads the cut block to trolley in front of the autoclave for grouping. The cutting cart will back for new round cutting.
