The removable movable sieve jigging dry-type coal picking machine is designed and developed aimed at a small-size coal mine, the selection rate of coal of our country can be sharply increased, and the economic and social benefits of coal in national economy are increased.

Description

Technical field [0001] The invention relates to coal sorting equipment, in particular to a movable movable screen jigging dry coal separator. Background technique [0002] Coal is the food of enterprises, accounting for 30% of the world's primary energy consumption. 40% of the world [0003] The power generation of China comes from coal, which accounts for about 75% of my country’s energy production and consumption. my country has abundant coal reserves. The coal-based energy structure will not change in the next 30-50 years. The status of coal's energy base will not change. With the improvement of coal mining mechanization and changes in geological conditions, the quality of raw coal tends to gradually deteriorate. Coal preparation is the most important means of improving coal quality and an important production link in the coal industry. After the raw coal is washed and processed, the pyrite can be reduced by 60%-70%. Burning washed coal can effectively reduce smoke, dust ...
