Abstract

The invention relates to the field of coal mining, in particular to a rotary raw coal iron removal device for coal mining, which comprises a support underframe, a slotted support disc, a separation plate, a classification frame, a screening assembly and the like. Two slotting supporting discs are fixedly installed on the supporting bottom frame, a separating plate is welded to the two slotting supporting discs together, two classifying frames are arranged on the supporting bottom frame, and the screening assembly is arranged on the supporting bottom frame. Metal objects of different sizes in coal can be adsorbed through the magnetic rollers, the magnetic rollers cannot adsorb the coal, the coal can slide into the inner classification frame, the separation plates can block the metal objects, the metal objects can fall into the outer classification frame, and the purpose of sorting the coal and the metal objects is achieved.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to a rotary raw coal iron removal device for coal mining. Background technique [0002] Coal is an important energy source in my country, accounting for 75% of the primary energy. Raw coal is mixed with various mineral impurities during the production process, and rocks and other impurities from the roof and floor are inevitably mixed with the roof and floor during the mining and transportation process. With the improvement of coal mechanization and the change of geological conditions, the quality of raw coal will become worse and worse, so it is necessary to sort raw coal. [0003] The main task of coal preparation is to sort and discard a large amount of gangue and remove metal objects of different shapes and sizes mixed in the raw coal, which can reduce the ineffective transportation of railways, improve the quality of raw coal, and reduce the pollution of coal to the atmosphere. In th...
