Description
Technical field
The utility model belongs to cement grinding field, and in particular to a kind of cement Joint grinding system and equipment.
Background technology
Mainly there are two kinds of combined grinding technique and respective grinding process in the cement grinding process country at present.Combined grinding be by
The various materials for constituting cement component mix the mode that grinding produces cement by a certain percentage.Technique generation at home
Sheet form is the Joint grinding system being made up of roll squeezer+grinding machine, is currently in the stage of being mature on the whole, at home cement grinding system
Occupied an leading position in system.The advantage of the process system is that technology arrangement is fairly simple, system production capacity is high, energy consumption is relatively low, overall throwing
Money is relatively fewer.Major defect is that the Optimized Matching and cement each component grain composition that cannot realize cement each component rationally divide
Cloth.Separate compiling is to carry out the various materials for constituting cement component separate compiling and then carry out allotment by a certain percentage to produce each
A kind of mode of production of kind cement.Compared with Joint grinding system, technology arrangement is relatively complicated, and system equipment and warehouse compartment are relative
It is more, invest relatively large, grinding pow consumption is of a relatively high.Advantage can be achieved on the Optimized Matching and each group of cement each component
The reasonable layout of part grain composition, so as to realize distributing rationally for cement raw material.
The principal element for influenceing cement performance is the mineral composition and intensity of clinker, mixing material kind and addition content, compares table
Grain composition after area, each component grinding etc..Relevant research in recent years shows, according to cement each component " interval narrow ditribution,
Overall distribution wide " grain composition model and Optimized Matching principle, will prepare cement raw material by the complementary Binder Materials of high activity, water
The complementary Binder Materials of mud clinker, low activity（Or inert filler）Be placed in complex cement it is thin, in, coarseness it is interval, prepare three
Interval complex cement.Cement clinker consumption can reduced, complementary Binder Materials is being improved（The particularly complementary gelling material of low activity
Material）While volume, the performances such as intensity, the volume stability of complex cement are significantly improved.
What the country used at present is that leading Joint grinding system is producing complex cement technique with roll squeezer+grinding machine, will
Low activity mixing material lime stone, waste residue and flyash etc. and clinker+gypsum are mixed in proportion and grinding and carry out outer mixing
A certain amount of miberal powder produces complex cement, it is impossible to realize that the Optimized Matching and cement each component granular-grade of cement each component coordinate
Reason distribution problem, is unfavorable for reduces cost, improves cement high-quality.In combined grinding, slag, clinker and flyash, stone
The mixing material grindability such as son, slag differs greatly, it is easy to " selective grinding " phenomenon occur, and grindability is good, the material of poor activity
Material such as stone is easily realized and more than required fineness, and the poor material of grindability such as slag, clinker then cannot get institute
It is required that fineness, its corresponding activity is also not in full use.For example：It is raw material to use slag, clinker, stone, flyash
Combined grinding technique, when the specific surface area of cement reaches 350 ㎡/kg, the specific surface area of slag typically can only achieve 2
3 0~2 80 ㎡/kg or so, the specific surface area of clinker is in 260~310 ㎡/kg or so.And the active potentiality of slag should grind
To 450 ㎡/more than kg, clinker should be ground to 350 ㎡/more than kg, and its activity can just accordingly played.And as low activity
Stone, flyash of complementary Binder Materials etc. because occur " selective grinding phenomenon " its specific surface area then more than 350 ㎡/
Kg, occurred in that grinding, increased power consumption.Therefore, country's roll squeezer+grinding machine is leading Joint grinding system combined grinding now
The method of cement directly affects distributing rationally for the performance of cement, production cost even raw material resources.
Utility model content
The technical problems to be solved in the utility model is that the Joint grinding system for generally using cannot realize resource optimization
Configuration, the need for being unfavorable for low cost, high-quality, low-carbon environment-friendly production cement, there is provided one kind realizes the reduction of manufacture of cement cost,
