Gravel production gradation adjustment device

Abstract

The invention discloses a gravel production gradation adjustment device. The gravel production gradation adjustment device comprises a grading screen, and the grading screen comprises multiple layers of screens; the screen I of which the mesh diameter is 4.75 mm, the screen II of which the mesh diameter is 3 mm, the screen III of which the mesh diameter is 1.25 mm, the screen IV of which the mesh diameter is 0.25 mm, the screen V of which the mesh diameter is 0.16 mm and the screen VI of which the mesh diameter is 0.075 mm are sequentially arranged from top to bottom; the discharge ends of the screens are connected to material collection hoppers; each material collection hopper is connected to one bin through a pipeline; weighing devices are arranged at discharge openings of the bins; a belt conveyer is arranged in front of the weighing devices; and the discharge end of the belt conveyer is connected to a stirring machine. According to the gravel production gradation adjustment device, classification of six-grade stone of which the particle sizes are 0 mm to 0.075 mm, 0.075 mm to 0.16 mm, 0.16 mm to 0.25 mm, 0.25 mm to 1.25 mm, 1.25 mm to 3 mm, and 3 mm to 4.75 mm can be achieved, weighing is achieved through the weighing devices, finally, stone of the required gradation is matched according to different utilization requirements and is put into the stirring machine to be stirred and mixed, stone powder of the required gradation can be better prepared, preparation quality of stone powder is improved, selectivity is high, and gradation adjustment can be effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of sandstone production and grading equipment, and in particular relates to a sandstone production grading adjustment device. Background technique [0002] In the existing sand and gravel production plants, the crushed stones are usually classified into 2 to 3 grades, which cannot complete automatic batching, and there are few classifications, and the application occasions are narrow. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sandstone production gradation adjustment device to solve the problems existing in the prior art. [0004] The technical scheme adopted by the present invention is: a device for adjusting the gradation of sand and gravel production, including a grading sieve, the grading sieve includes a multi-layer screen, and a screen with a mesh diameter of 4.75 mm and a mesh of 3 mm are arranged sequentially from top to bottom. ...
