Description

Drum-type rotating screw vibrating screen classifier
Technical field
The utility model relates to a kind of screening machine, is specifically related to a kind of drum-type screening machine, particularly a kind of drum-type rotating screw vibrating screen classifier.
Background technology
Screening machine is the relative motion that utilizes bulk granular material and compass screen surface, makes the part particle see through sieve aperture, the materials such as sand, gravel, rubble is divided into the vibration screening machinery equipment of different stage by granular size.The particle rank of screening depends on compass screen surface, and compass screen surface divides three kinds of comb grid, plate sieve and mesh screens.The comb grid are applicable to sieve large granular materials, and comb grid slit is 1.1 to 1.2 times of screenings particle diameter, generally should not be less than 50 millimeters.The plate sieve is formed by the steel plate punching, rounded, the square or rectangle in hole, and the aperture is generally 10 to 80 millimeters, and service life is longer, is difficult for stopping up, and is applicable to sieve medium grain.Mesh screen is weaved into or is welded into by steel wire, and the hole is square, rectangle or strip, and aperture commonly used is generally 6 to 85 millimeters, and the strip sieve aperture is suitable for sieving moist material, and the advantage of mesh screen is that effective area is larger.
Vibrating screen classifier is the visual plant of solid material classification, is widely used in the industries such as mine, building materials, coal separation, the energy, chemical industry.Form is divided into two kinds of a formula and hangings substantially.The most general with the seat formula generally speaking, vibration source adopts eccentric block or eccentric shaft, and two kinds of vibration source mixing are used also comparatively general.Operation principle: vibrating screen classifier is the exciting force that utilizes eccentric block or eccentric shaft to produce, make sieve nest do periodically double vibrations along the exciting force direction, material circumference on compass screen surface is beated, regular to desired compass screen surface the stock grading of different size by different sieve apertures, be transported to the appointed area after compiling, to reach classification or de-mediated purpose.Can adjust amplitude by the weight of adjusting eccentric block.
