Description

technical field

[0001] The invention relates to a device for screening mixed sand into particles of different sizes, in particular to a static environmental protection automatic grading sand screening machine. Background technique

[0002] Existing sand making classifiers are generally open vibrating screens, and its structure includes a motor, a classifying wheel and a body. During normal operation, the motor is started, and the raw materials are screened into particles of different sizes after passing through the classifying wheels at all levels; the method has the following disadvantages : 1. Power consumption and energy consumption; 2. The dust is very large and the pollution is serious, which affects the health.

[0003] The Chinese patent application No. 94105834.4 discloses an invention patent named "classifier", which includes two coaxial conical shells inside and outside, an outer shell shell cover and a plurality of rotating parts located on the top edge of the inn...
