Description
Technical field
The utility model relates to screening plant, especially a kind of comb grizzly subset.
Background technology
The solid granular material sieves, and purpose is for granule materials is classified by granularity, to satisfy the demand of different production technologies, requires to accomplish continuous, efficient, reliable during screening.At present, the screening operation adopts screening machine to carry out usually, utilizes the relative motion of bulk granular material and compass screen surface, makes the part particle see through sieve aperture, thereby material is divided into different stage by granular size.The sized granules rank depends on compass screen surface, and compass screen surface divides three kinds of comb grid, plate sieve and mesh screens.The comb grid are made of the some gratings that are arranged side by side, and have the gap between the grating to constitute comb grid slit, and comb grid slit is 1.1～1.2 times of screenings particle diameter.The plate sieve is formed rounded, the square or rectangle in hole by the steel plate punching.Mesh screen is weaved into or is welded into by steel wire, and the hole is square, rectangle or strip.
Present screening machine divides gravity flow screen and portable screen two classes, again component of rotation sieve and vibratory sieve.Gravity flow screen is unpowered sieve, adopts comb grid structure mostly, is contained in the equipment importation top, falls into the material that prevents ultra-specification.Portable screen commonly used is a vibratory sieve, and vibratory sieve has eccentric gyration sieve, inertia vibrating screen and resonance screens etc., and its common feature is that compass screen surface is made high frequency, small amplitude motion, and the material on the compass screen surface is emanated.The amplitude of eccentric gyration sieve does not change with what of oversize material, and screen size is generally 13～100 millimeters, can reach 100～250 millimeters, and maximum pan feeding particle diameter can reach 300 millimeters.Inertia vibrating screen single shaft arranged with twin shaft, the motion of its vibrational system is relevant with weight of material and spring rate, so the increase and decrease of material directly influences the amplitude size on the compass screen surface, be applicable to the occasion that feed amount and change of size are little, be usually used in the screening of second road, screen size is 0.5～100 millimeter, and maximum pan feeding particle diameter is between 100～500 millimeters.The screen box of resonance screens is worked under resonance condition, but need only supply with the just continuous operation of energy that overcomes the screening kinetic damping, and power consumption is less, and in being applicable to, the fine screening, screen size is 0.5～80 millimeter, and maximum pan feeding particle diameter is 100 millimeters.
Along with the development of producing, often need under the situation of not upgrading screening plant, adjust the parameter of screening plant at any time, thereby produce varigrained granule materials, adapt to the needs of production technology.Therefore existing vibratory sieve obviously can not meet the needs of production.
