Abstract
The invention discloses a roller screening machine, which has the grinding and grading functions, and belongs to grinding and grading equipment in cement, metallurgy and chemical industries. The roller screening machine comprises an FPP (floating point processor) mill, a prismoid diffusion grader, a coupling barrel, a feeding hole 1, a feeding hole 2, a discharge hole 1 and a discharge hole 2. The roller screening machine is integrated with the grinding function of the FPP mill and the grading function of the prismoid diffusion grader, and is simple in structure; the civil and steel structure engineering for putting the prismoid diffusion grader is saved; the graded crude powder directly flows into the roller screening machine at the same time; conveyer equipment for returning the crude powder to the FPP mill is saved; and the targets of compact process arrangement, small occupied space, low investment cost, low operating cost and low engineering investment are achieved.
Description
Technical field:
The present invention relates to a kind of roll screening machine, particularly a kind of roll screening machine with grinding, grading function, belong to the grinding classifying equipoment in cement, metallurgy, chemical industry.
Background technology:
In the cement grinding industry, after grog grinds through pre-milling equipment FPP abrasive dust, must carry out sorting by classified equipment (as: terrace with edge diffusion grader CN201220243386.5 or V-type powder concentrator), coarse fodder returns in the FPP mill by conveying equipment, and fine powder enters lower road equipment through conveying equipment and carries out grinding, selection by winnowing formation finished product.Above-mentioned this grinding process, its grinding and grading function separate, thereby process equipment is more, complicated layout, the occupation of land space is large, and cost of investment is large simultaneously, and the Engineering Overall cost is high.
Summary of the invention:
The present invention seeks to provides a kind of equipment few in order to overcome above-mentioned defective of the prior art, and technology arrangement is compact, and the occupation of land space is little, reduced investment, and operating cost is low, the roll screening machine that total investment of engineering is lower.
Technical scheme of the present invention is: roll screening machine comprises by FPP mill, terrace with edge diffusion grader, coupling tunnel, charging aperture one, charging aperture two, discharging opening one, discharging opening two forming.Roll screening machine is characterised in that, terrace with edge diffusion grader is fixed on FPP mill top by coupling tunnel.Described roll screening machine has two charging apertures, is charging aperture one and charging aperture two; Described charging aperture one is FPP abrasive dust mill material inlet; Described charging aperture two is the thickness compound charging aperture of terrace with edge diffusion grader.Described terrace with edge diffusion grader, coarse fodder is fed directly to the FPP mill from central tube.
Operation principle of the present invention is: by the raw material of grinding, enter from the charging aperture one of roll screening machine, after milling through the roll screening machine grinding roller, the thickness compound draws off from discharging opening one, be sent to roll screening machine top charging aperture two by bucket elevator, after the classification of thickness compound through terrace with edge diffusion grader, coarse fodder is fed directly to roll screening machine from central tube and continues grinding, and fine powder draws off from discharging opening two and enters next procedure and be processed into finished product.
The invention has the beneficial effects as follows: roll screening machine rolls into one the grading function of FPP abrasive dust mill function and terrace with edge diffusion grader, simple in structure, save frame and put terrace with edge diffusion grader civil engineering and structural steelwork, the meal that is graded simultaneously is fed directly in roll screening machine, saves the conveying equipment that meal turns back to the FPP mill, reaches the technology arrangement compactness, take up an area the space little, cost of investment is economized, and operating cost is low, and construction investment is low.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing:
The structure chart of Fig. 1 roll screening machine
In figure: 1FPP mill 2 terrace with edge diffusion grader 3 coupling tunnel 4 charging aperture one 5 charging aperture 26 discharging opening one 7 discharging openings two
The specific embodiment:
As shown in Figure 1, roll screening machine comprises by FPP mill (1), terrace with edge diffusion grader (2), coupling tunnel (3), charging aperture one (4), charging aperture two (5), discharging opening one (6), discharging opening two (7) forming.Roll screening machine is characterised in that, terrace with edge diffusion grader (2) is fixed on FPP by coupling tunnel (3) and grinds (1) top.Described roll screening machine has two charging apertures, is charging aperture one (4) and charging aperture two (5); Described charging aperture one (4) is FPP mill (1) grinding material inlet; Described charging aperture two (5) is the thickness compound charging aperture of terrace with edge diffusion grader (2).Described terrace with edge diffusion grader (2), coarse fodder is fed directly to FPP mill (1) from central tube.
In the present embodiment, the operation principle of roll screening machine is: by the raw material of grinding, enter from the charging aperture one (4) of roll screening machine, after milling through the roll screening machine grinding roller, the thickness compound draws off from discharging opening one (6), be sent to roll screening machine top charging aperture two (5) by bucket elevator, after the classification of thickness compound through terrace with edge diffusion grader (2), coarse fodder directly returns roll screening machine from central tube and carries out grinding, and fine powder draws off from discharging opening two (7) and enters next procedure and be processed into finished product.
