Abstract
Screen mill is the equipment of a kind of pulverizing or brittle minerals such as coal in small, broken bits, gangue.It can grind the mineral limit, and the limit screening removes foreign material side by side.Tramp iron separator, disintegrating machine, sieve and the elevator that can replace present use.Its major technique feature is: after mineral enter the cylindrical shell of rolling, smashed with levigate by the rod iron in the cylindrical shell.Then enter in the circular arc sieve and sieve by the grating gap of lining plate.The saturating sieve of fines is qualified products, and coarse fodder automatically returns in the body through the returning charge mouth, continues levigate again.Difficult broken foreign material can be overflowed automatically by tail.
Description
The present invention relates to the special equipment of a kind of comminuted coal spoil and coal.This equipment is specially adapted to the in small, broken bits of brittle mineral and pulverizes.
At present, to the pulverizing of mineral such as gangue, coal or in small, broken bits, all adopt multiple devices such as tramp iron separator, disintegrating machine, sieve and elevator to form the closed cycle operation.Operating efficiency is lower, deficiency in economic performance.
The present invention will provide a kind of screen mill that can replace multiple devices operation and high efficiency.
Operation principle: in the cylindrical shell that rotates, many rod irons are housed, after the mineral that need pulverize are packed into, are smashed also levigate by rod iron.Bar scaleboard is housed in the cylinder, is smashed or levigate mineral enter by the discharge gate on lining board clearance and the cylinder in the circular arc sieve of cylinder outside, tiny granularity sees through the circular arc sieve and is qualified products, and the mineral of thick granularity are mentioned by the riser in the circular arc sieve.When playing certain altitude, the returning charge door is opened automatically, and the mineral of thick granularity just automatically return to go in the cylindrical shell through the returning charge mouth again and smashed with levigate.Difficult broken foreign material are discharged by the cylindrical shape tail sheet that is contained in the cylinder tail end.
Concrete structure of the present invention is provided by following examples and accompanying drawing thereof.
Fig. 1 is the transverse cross-sectional view of a kind of concrete structure of the present invention.
Fig. 2 is the longitudinal sectional drawing of Fig. 1 screen mill.
With reference to Fig. 1, cylinder (1) is rolled by steel plate and forms.Be with the liner plate of being made up of grating (2) in cylinder (1), grating is cast by potassium steel, leaves the gap between the grating.Rod iron (3) is housed in the liner plate (2).Cylinder (1) outside is with circular arc sieve (4), and the screen cloth of circular arc sieve (4) is formed by braided steel wire.Cylinder (1) is provided with discharge gate (5) and returning charge mouth (6), and returning charge door (7) is housed on returning charge mouth (6).Returning charge door (7) automatic shutter of reliably conducting oneself with dignity.Also be provided with returning charge mouth (6) and returning charge door (7) on the liner plate (2).Be provided with riser (8) in the circular arc sieve (4).With reference to Fig. 2, the front end of cylinder (1) is equipped with cast steel roller (9).Central authorities leave charging aperture (10), and cast steel roller (11) is equipped with in the rear end of cylinder (1), and central authorities leave flash mouth (12).Cylindrical shape tail sheet (13) is housed on flash mouth (12), and its screen cloth is by braided steel wire.Above-mentioned these parts are formed cylindrical shell.Cylindrical shell drops on the carrying roller (14), and carrying roller (14) is installed on the base (15).For stoping the cylindrical shell play, be provided with upright wheel (16) at cylindrical shell one end.Below base (15), be provided with funnel (17).
Mineral (18) enter liner plate (2) by charging aperture (10).When motor (19) drove the rotation of carrying roller (14) drive cylindrical shell, mineral (18) rolled with rod iron (3) upset.Rod iron (3) with mineral (18) smash, levigate.Broken thin mineral just enter in the circular arc sieve (4) by the gap and the discharge gate (5) on the cylinder (1) of liner plate (2).Through screening, the saturating sieve of release mesh is for qualified products, by funnel (17) output.Thick granularity is raised plate (8) to be mentioned, and when mentioning certain altitude, returning charge door (7) leans on from reopening, and thick granularity mineral just fall into liner plate (2) through returning charge mouth (6).Difficult broken foreign material enter tail sheet (13) through flash mouth (12) and discharge.When cylindrical shell was rotated further, returning charge door (7) was closed by deadweight.
