Abstract
The utility model relates to a diameter variable rotary cylinder roll circular grinder. A sliding crawler or a supporting wheel are utilized to support a diameter variable rotary cylinder, a pressed roll shaft and a rolling hoop which are rotated by a transmission mechanism to grind various mineral substances, such as limestone, cement clinker, etc. The diameter variable rotary cylinder roll circular grinder is used for solving the problems that the existing grinding device has the disadvantages of high power consumption, high iron consumption, poor grinding effect, etc. The utility model is mainly characterized in that the diameter variable rotary cylinder roll circular grinder adopts the diameter variable cylinder body, the rolling loop in the shape of a curved line section, and a lining board of the curved line of the internal wall of the cylinder body, so the mineral substances can be ground in a hierarchical mode; thereby, the grinding efficiency is raised, and the particle pattern is improved. The utility model adopts the offset of the roll shaft, so the mineral substances can be ground effectively, the resistance moment of the rolling loop and the roll shaft can be decreased, and the service life and the energy utilization ratio of the diameter variable rotary cylinder roll circular grinder can be improved.
Description
Reducing revolves a collars grinding machine, is a kind of energy-conservation milling equipment during the material bed is pulverized, and is applicable to the milling equipment of all kinds of mineral processing.Be specially adapted to that mineral such as lime stone, clinker carry out grinding in the manufacture of cement.Domestic existing milling equipment mainly is tube mill, Vertical Mill, but these grinding machines are all being deposited shortcomings such as the efficient of material in mill is low, iron loss is high, and noise is big.France FCB a kind of milling equipment that is used to process of report is called the HORO mill, though the HORO mill has improved problems such as efficient is low, iron loss height, also exists classifying capability poor, the not high shortcoming of the spherical coefficient of fine powder finished product.
The purpose of this utility model is that classifying capability is strong in order to overcome, outside the not high weak point of the spherical coefficient of fine powder finished product, design a kind of utilization rate height, energy consumption is low, compact conformation, vibration are little, can extension set pulverize, improve granule-morphology, improve a collars grinding machine that revolves of grinding effect.
Be described in detail the utility model below in conjunction with accompanying drawing.
Fig. 1-structural representation of the present utility model.
The A-A view of Fig. 2-Fig. 1.
1-roll shaft among the figure, the 2-bearing, the 3-seal cover, 4-rolls ring, the 5-liner plate, 6-discharge end cylindrical shell, 7-takes turns band, 8-power transmission shaft, 9-feed end tube, 10-liner plate, 11-backing plate, the 12-pipe of selecting materials, 13-support, 14-discharge nozzle
Diameter variable rotary cylinder circular grinder, as shown in Figure 1.
A horizontal hollow cylinder (9) that is supported on two groups of crawler shoes (13) or the support roller, cylindrical shell (9) internal diameter can Be cylindrical, garden platform shape or surface of revolution shape, the roll shaft center is not on the vertical line of crossing the cylindrical shell center. By Transmission mechanism (8) driven rotary is established a roll shaft (1) in the cylindrical shell, the one or more differences of suit are disconnected on the roll shaft The two ends of rolling ring (4) roll shaft of face shape are installed on the outer bearing (2) of cylindrical shell, add suitable pressure on the bearing Power F can adopt hydraulic means, also can adopt weight to load or the nonlinear spring pressuring method. Powder Mill is during operation, the material of being sent into by feed pipe (12) under rotary barrel drives, the roll shaft by pressure is arranged and The pressure span of rolling between ring and the cylinder inboard wall is pulverized, controls and dust pollution in order to prevent that material flow is scattered and disappeared, The cylindrical shell two ends are arranged on end cover (3). In the accompanying drawing 1, the diameter of cylindrical shell discharge end cylindrical shell 6 is greater than feed end Liner plate 5 in the diameter of cylindrical shell 9, discharge end tube is to adopt trench liner that liner plate or curve liner plate also can be installed, Strengthen the nodularization function in fine powder district. Along with object repeatedly cycles through the pressure span and to discharge end in cylindrical shell Flow, finally from discharge nozzle (14) rank, finish its pulverized technical process.
The utility model is compared with existing HORO mill, has following good effect:
(1) because the discharge end barrel diameter suitably amplifies, after having adapted to material and being pulverized, heaps the variation that volume increases, thereby can reduce the thickness of discharge end cylindrical shell powder, improve grinding environment fine powder.
(2) roll ring and help the classification of material is pulverized, and play the adjusting thickness of feed layer, regulate the effect of normal pressure and shearing force, strengthen grinding effect.
(3) the curve liner plate with roll the ring positive camber, help the nodularization of fine powder, and the effect of even pulverizing arranged, thereby can improve the granule-morphology of the product that prior art produces.
(4) roll shaft with roll ring and depart from the vertical axis of cylindrical shell, can strengthen granulitization to material, reduce roll shaft, roll the rub-moment of ring.
(5) with existing ball mill, rod mill is compared, and has the effect of energy-conservation 30-50%, and can reduce iron loss 50%, compares with existing extruding, and impressed pressure reduces by 10 multidigits, saves and selects valency 15-25%, and the grain composition and the microscopic appearance of cement products improve.
Realize best way of the present utility model, as shown in drawings: the roller of drawing by " φ 1800/1960 * 1800 (mm) " specification grinds the structure chart of part.Horizontal cylinder is welded as a whole by little cylindrical shell of feed end (9) and discharge end large cylinder (6).Transmission mechanism (8) adopts straight-tooth garden post circle.Supporting mechanism (13) adopts crawler shoe, keeps the normal rotation of cylindrical shell by wheel band (7) and backing plate (11).Cylindrical shell feed end inwall adopts flat liner plate (10) cylindrical shell discharge end inwall to adopt trench liner (5), and the shape of groove matches with the outer shroud curved surface that rolls ring (4).The working surface of roll shaft (1) is the garden cylindricality, helps reducing the surface abrasion of collar portion.At the hydraulic coupling device versatility is arranged as figure, do not give table sand in the drawings.And crawler shoe supports (13), bearing allocation (2), and end cover (3), feed pipe (12) and discharge nozzle (14) all adopt reduced representation in the accompanying drawings.
Claims (4)
1, reducing revolves a collars grinding machine, by reducing rotary barrel, roll shaft, roll the ring form, it is characterized in that a horizontal hollow reducing cylindrical shell (9) that is supported on two groups of crawler shoes (13) or the support roller, a roll shaft (1) is set in the cylindrical shell (9), what roll shaft (1) was gone up suit different section shape rolls ring (4), the two ends of roll shaft (1) are installed in the outer bearing (2) of cylindrical shell, at the inwall and the roll shaft of cylindrical shell (9), to roll between the ring (4) be the material bed of material.
