Problems solved by technology

At present, the existing coal crushing device has low efficiency and incomplete crushing, and it is difficult to meet the needs of the market
[0004] The coal excavated from the underground is relatively humid. Most of the coal contains more than 10% free water and about 10% internal water. Therefore, the coal has to evaporate about 20% of the water during the combustion process, so that Greatly reduces the calorific value of coal

Abstract

The invention discloses a multifunctional coal conveying device. The multifunctional coal conveying device comprises a bearing plate; a support part is mounted on the bottom surface of the bearing plate; a crushing device for crushing coal is arranged on one side of the upper surface of the bearing plate; and a grinding device for grinding crushed coal particles is arranged on the other side of the upper surface of the bearing plate. The multifunctional coal conveying device is simple in structure and novel in design, and can integrate the functions of crushing, grinding, transporting and drying.

Description

technical field [0001] The invention belongs to the technical field of coal mines, and in particular relates to a multifunctional coal conveying device. Background technique [0002] Coal is a solid combustible mineral that was gradually formed by ancient plants buried underground through complex biochemical and physicochemical changes. Coal is the most widely distributed fossil energy resource in the world. It is known as black gold and the food of industry. It has been one of the main energy sources used by the human world since the eighteenth century. [0003] In recent years, my country's industrialization process has accelerated, and the demand for coal has increased. Due to the large volume and uneven shape of the freshly mined raw coal, there are many inconveniences in the process of transportation and use, so it generally needs to be crushed before transportation. At present, the existing coal crushing device has low efficiency and incomplete crushing, and it is di...
