Abstract

The invention discloses a novel combined screening machine which comprises a tank, an air inlet, a feed hopper, screen cloth and a discharge opening. The air inlet (2) is formed in the upper portion of the tank (1), and an air distributing plate (3) is arranged between the air inlet (2) and the tank (1); the feed hopper (7) is arranged on the top of the tank (1), and a feed guide pipe (5) is arranged below the feed hopper (7); a spiral distributing machine (6) is arranged between the feed hopper (7) and the feed guide pipe (5); the upper end of the screen cloth (4) is fixed to the inner wall of the tank (1) and is hinged to the rear side of the feed guide pipe (5), and the lower end of the screen cloth (4) is hinged to the upper end of an arc-shaped partition plate (12); the lower end of the arc-shaped partition plate (12) extends between a pair of rolls (13) which are fixed to the inner wall of the tank (1). The novel combined screening machine has the obvious advantages that the novel combined screening machine is simple in structure, convenient to operate and high in mud (or stone) powder removing efficiency, is economical and practical and can run stably and reliably, and the product grading quality can be guaranteed.

Description

technical field [0001] The invention belongs to the field of mining processing machinery, and is a mechanical device for simultaneously classifying artificial sand, adjusting continuous grading of particle diameters, removing mud powder content, and producing construction sand meeting national standards. It can also be used in the technical field of production where other metal and non-metal minerals have the same product standard requirements. Background technique [0002] The existing typical artificial sand production equipment includes vibrating screen, air screen, powder removal, water washing equipment and other technologies. At present, the application of these equipment technologies still exists that the artificial sand particle gradation produced cannot meet the construction sand standard, 150~ Particles in the 30μm and 300~600μm sections are insufficient, the particle gradation is poor, the content of mud powder (or stone powder) is large, and the production qualit...
