Novel tooth roller machine for crushing coal gangue

Abstract

The invention relates to a novel tooth roller machine for crushing coal gangue. The novel tooth roller machine comprises a rack, the first tooth roller mechanism is fixedly arranged on the rack and is in transmission connection with the first driving mechanism; the second tooth roller mechanism is movably arranged on the rack and is in transmission connection with the second driving mechanism; a crushing opening for extruding and crushing coal gangue is formed between the second tooth roller mechanism and the first tooth roller mechanism; the pressure system is connected with the second tooth roller mechanism and is suitable for driving the second tooth roller mechanism to perform extrusion movement towards the first tooth roller mechanism; and a tooth roller of the first tooth roller mechanism and a tooth roller of the second tooth roller mechanism rotate relatively so as to extrude and crush the large-particle-size coal gangue entering the crushing opening. The coal gangue with the particle size of about 500 mm can be crushed into coal gangue with the particle size of about 30-50 mm, and the requirement of secondary feeding is met.

Description

technical field [0001] The invention relates to a new type of toothed roller machine for coal gangue crushing. Background technique [0002] There is no special equipment for pulverizing coal gangue into powder at present, and the equipment for pulverizing ore into powder is mainly borrowed. Mainly include: jaw crusher, vertical shaft crusher, ball mill and other equipment to achieve coal gangue crushing, jaw crusher has low efficiency, high production cost, frequent replacement of wearing parts, and monthly replacement of jaw plates, which is time-consuming and labor-intensive . The hammer head of the vertical shaft crusher is replaced frequently, once a week. Frequent replacement not only increases the cost, but also cannot form automated production. The ball mill uses steel balls as the medium to realize the powdering of materials. The ball mill needs one kilogram of steel balls to produce one ton of coal gangue. According to the output of 150 tons per hour, 20 hours pe...
