Abstract
The invention belongs to the technical field of grinding in a cement industry, in particular relates to a vertical type pin roll winnowing mill for grinding cement clinkers. The vertical type pin roll winnowing mill mainly comprises an air outlet taper 1, a winnowing device 2, a feeding pipe 3, an upper shell 4, a grinding ring device 5, a grinding disc 6, a lower shell 7, a grinding roll device 8, a support 9 and a transmission device 10. The grinding ring device 5 composed of a rotary grinding ring 13 and a fixed grinding ring 12 is arranged above the grinding disc 6 of the vertical type pin roll winnowing mill; and materials rolled by a grinding roll are further grinded by the grinding ring device composed of the rotary grinding ring 13 and the fixed grinding ring 12, so as to greatly change the shape of cement grains. Powder fineness of a finished product separated by the winnowing device 2 is further optimized so that the cement finished product reaches a qualified water demand requirement. Meanwhile, when the vertical type pin roll winnowing mill is used for grinding the cement, the energy is saved by 30-40% compared with that of the traditional ball mill, the energy is saved by 15-20% compared with that of a grinding system composed of a rolling machine and the ball mill, and the power is saved by more than 10% compared with that of a vertical mill system.
Description
Technical field:
The invention belongs to the grinding technology field of cement industry, relate in particular to a kind of vertical discaling roll selection by winnowing mill that is used for the pulverizing cement grog.
Background technology:
At present, the combination grinding formed by independent ball mill, ball mill and roll squeezer of cement grinding equipment and vertical roller grinder etc.With independent ball mill pulverizing cement; Because power consumption is high; In newly-built cement grinding production line, seldom adopt, and the more independent ball mill pulverizing cement obvious energy conservation of combination grinding system that ball mill and roll squeezer are formed, its grinding system power consumption is more than 31kWh/t.
Adopt the vertical roller grinder pulverizing cement; Its grinding system power consumption is at 26kWh/t, and is all lower than the combination grinding system power consumption of independent ball mill and ball mill and roll squeezer composition, but uses the cement of vertical roller grinder grinding at present; Its granule-morphology and cement granules irrational distribution; The water requirement of cement is big, for concrete manufacturing enterprise, be difficult to accept, thereby the system process equipment of promotion and application vertical roller grinder pulverizing cement does not form market potential as yet.
Summary of the invention:
The present invention provides a kind of vertical discaling roll selection by winnowing mill to the anxious difficult problem to be solved of above-mentioned vertical roller grinder grinding.With vertical discaling roll selection by winnowing abrasive dust mill cement, its energy consumption is low, produces its granule-morphology of cement and cement granules and adapts to market demands, and the cement water requirement is little, and concrete quality is high.
Technical scheme of the present invention is:
Vertical discaling roll selection by winnowing mill mainly is made up of air-out cone, pneumatic separation device, feed pipe, upper body, bull ring device, mill, lower case, Burnisher apparatus, bearing and transmission device.The top of vertical discaling roll selection by winnowing mill mill is provided with the bull ring device, and the bull ring device is by the rotation bull ring, fixedly bull ring and external adjustment device are formed.The rotation bull ring is fixed on the plane of mill, and the plane is provided with two groups of tooth lappings on the rotation bull ring, and the spacing between two groups of teeth is 5-30mm, and tooth depth 5-30mm is in tilted layout.Fixedly bull ring is fixed on the upper body through bearing support, fixedly is provided with tooth lapping on the lower plane of bull ring, tooth depth 5-30mm, and radioactive ray are arranged.The external adjustment device is arranged on the outside of upper body, can regulate rotation bull ring and the fixing gap between the bull ring working face easily, guarantee the rotation bull ring and fixedly bull ring bring into play rational mill efficiency.
When vertical discaling roll selection by winnowing abrasive dust ground cement, material fed from feed pipe, under the rotating grinding board action of centrifugal force; Material moves to mill periphery, through grinding roller roll grinding after, material get into the rotation bull ring and fixedly the grinding chamber formed of bull ring continue to grind refinement; By the material behind the grinding under the effect of mill outside high velocity air; Fine powder is thus lifted to and carries out classification in the pneumatic separation device, and finished product is discharged from the air outlet of air-out cone, and coarse fodder falls back to mill relaying continued powder mill.
Beneficial effect of the present invention:
Above the mill of vertical discaling roll selection by winnowing mill, be provided with by rotation bull ring and the fixing bull ring device formed of bull ring; To pass through the material after grinding roller rolls; Again through the rotation bull ring and fixedly the bull ring device formed of bull ring to the further grinding refinement of material; Significantly change the cement granules pattern, the powder fineness is further optimized in the finished product that pneumatic separation device is selected, and makes finished cement reach qualified water requirement requirement.Simultaneously, when grinding cement with vertical discaling roll selection by winnowing abrasive dust, than the energy-conservation 30-40% of traditional ball mill, the energy-conservation 15-20% of grinding system than roll squeezer and ball mill composition economizes on electricity more than 10% than vertical mill system.

The specific embodiment:
For further understanding content of the present invention, specify embodiments of the invention with reference to Fig. 1, Fig. 2.
Vertical discaling roll selection by winnowing mill mainly is made up of air-out cone 1, pneumatic separation device 2, feed pipe 3, upper body 4, bull ring device 5, mill 6, lower case 7, Burnisher apparatus 8, bearing 9 and transmission device 10.Bull ring device 5 is arranged on the top of mill 6, bull ring device 5 mainly by the rotation bull ring 13, fixedly bull ring 12, bracing frame 14 and external adjustment device 11 are formed.Rotation bull ring 13 is fixed on the plane of mill 6, and the plane is provided with two groups of tooth lappings on the rotation bull ring 13, and the spacing between two groups of teeth is 5-30mm, and tooth depth 5-30mm is in tilted layout.Fixedly bull ring 12 is fixed on the upper body 4 through bearing support 14, fixedly is provided with tooth lapping on the lower plane of bull ring 12, tooth depth 5-30mm, and radioactive ray are arranged.External adjustment device 11 is arranged on the outside of upper body 4, can regulate rotation bull ring 13 and the fixing gap between bull ring 12 working faces easily, guarantee the rotation bull ring and fixedly bull ring bring into play rational mill efficiency.
The operation principle of the vertical discaling roll selection by winnowing mill of the present invention is: material is from feed pipe 3 feedings; Under rotating grinding board 6 action of centrifugal force; Material moves to mill 6 periphery, through grinding roller roll grinding after, material gets into rotation bull ring 13 and proceeds to grind refinement with the grinding chamber that fixing bull ring 12 is formed; By the compound behind the grinding under the effect of mill 6 outside high velocity airs; Fine powder is thus lifted to and carries out classification in the pneumatic separation device 2, and finished product is discharged from the air outlet of air-out cone 1, and coarse fodder falls back to mill 6 relaying continued powders mill.
The bull ring device of being made up of rotation bull ring 13 and fixing bull ring 12 5 is set above the mill 6 of vertical discaling roll selection by winnowing mill; To pass through the material after grinding roller rolls; Again through rotation bull ring 13 and fixing bull ring 12 further grindings; Significantly change the cement granules pattern, the powder fineness is further optimized in the finished product that pneumatic separation device 2 is selected, and makes finished cement reach qualified water requirement requirement.
