Description
Technical field
The present invention relates to a kind of graded crushing device, particularly a kind of grate-cooler grog graded crushing device.
Background technology
Existing cement producing line adopts single-stage crushing machine to carry out the fragmentation of clinker mostly, and the clinker after fragmentation enters tube mill after the pre-grinding of roll squeezer to carry out whole grinding or directly enter tube mill carrying out whole grinding.Because clinker has the characteristic of easy broken difficult grinding, and according to statistics at cement industry, the effective rate of utilization about about 30% of disintegrating machine electric energy, and grinding machine only has about 2%, therefore the energy consumption of existing cement grinding production line is higher, is the workshop section that cement plant industry power consumption is the highest.In order to improve utilization rate of electrical, wish that more material particles refinement is operated in crushing stage and completes, make mill feed material little of certain degree, with economize energy, and the hardness of clinker declines with the rising of temperature, the fragmentation work of clinker is made to be easier to carry out, if therefore grog can be carried out sufficient fragmentation at clinker crushing stage, make its particle drop to best graininess into mill, then can reduce the power consumption in cement grinding stage significantly.
Summary of the invention
In order to solve the technical problem existed in background technology, a kind of clinker particles that can make is the object of the present invention is to provide to drop to into the best graininess of mill, to reduce the grate-cooler grog graded crushing device of the power consumption in follow-up grinding stage.
To achieve these goals, the present invention is by the following technical solutions: a kind of grate-cooler grog graded crushing device, comprise the first roller, second roller and the 3rd roller, the minimum range at the first described roller and the roll surface edge of the second roller is greater than the minimum range at the roll surface edge of the first roller and the 3rd roller, the roll surface diameter of the second described roller and the 3rd roller is less than the roll surface diameter of the first roller respectively, , the 3rd described roller diameter is more than or equal to the second roller diameter, the first described roller, the roll surface center of circle of the second roller and the 3rd roller forms acute triangle, with the roll surface center of circle of the first described roller for initial point, horizontal direction is x-axis, vertical direction is y-axis, the roll surface center of circle of the second described roller is positioned at first quartile, the roll surface center of circle of the 3rd described roller is positioned at first quartile or fourth quadrant, the line segment that the roll surface center of circle of the 3rd described roller and the roll surface center of circle of the first roller are formed and the angle that x-axis is formed are less than or equal to 45 °, the second described roller is positioned at the top of the 3rd roller, the gyratory directions of the second described roller and the 3rd roller is contrary with the gyratory directions of the first roller respectively.
The minimum range at the first described roller and the roll surface edge of the second roller is that grate-cooler goes out 1/4 of grog diameter.
The diameter of the second described roller is 4-8 times that grate-cooler goes out grog diameter.
The diameter of the 3rd described roller is 10-24 times that grate-cooler goes out grog diameter.
The diameter of the first described roller be not less than the second roller and the 3rd roller diameter and 1.5 times.
Adopt above technical scheme, the present invention has following beneficial effect: cement clinker particles can drop to into the best graininess of mill, to reduce the power consumption in follow-up grinding stage at crushing stage by the present invention.Compact conformation, connection and reasonable arrangement, is worth of widely use.
