4. method of the present invention is more favourable to the screening of adhesional wetting materiel from following several respects analysis:
The wing of adjacent shaft setting a. of the present invention is staggered; Rotating mechanism drives the swing in the same way synchronously of adjacent axle, and adjacent wing is heterodromous relatively, and a top like this material crowd part is thrown a part and descended; The material crowd receives shear action, and sieve is beneficial to breaks up the material that adheres to each other.
Each limit of sieve aperture was all doing relative motion when b. balance staff was swung, and sieve aperture can not stop up.
Also can clear up each other when c. wing is swung and be bonded on the adjacent axle and the particulate on the wing.
D. bulk materials receives a top support can total head not material bed at the granule that drops between centers, therefore is difficult for agglomerating.
E. can adapt to various character materials through adjustment hunting frequency and angle, swing is the mechanical forced motion, diminish with frequency gets higher or supplied materials amount unlike the vibratory sieve amplitude, also not can as roller picker with spiral screen axle rotating speed height spool can beat.
5. easy to maintenance, economize on the use of funds, when breaking down, only need to change certain balance staff or wing;
6. also has advantage simple in structure, sturdy and durable, as to work peace and quiet, dependable performance, easily collecting undersize material compared with vibratory sieve.
Adopt a kind of balance staff method for sieving of the present invention and balance staff screening machine thereof, it can cast material aside compass screen surface as vibratory sieve, and it is quiet reliable as roller picker, to work again, can obtain the existing inaccessiable effect of screening plant to adhesional wetting materiel; This technology is after in the industry, having overcome prior art prejudice; On the basis of research combination prior art; Creationary balance staff method for sieving and the balance staff screening machine thereof invented is a kind of brand-new dry screening method and apparatus, suits especially in coal and power industry, to be used for handling raw coal.
