Abstract
The utility model discloses a kind of natural scoria grindings to process the special rigid ball of abnormity.The abnormity steel ball is made of the protrusion of plain ball and attachment thereon, and the quantity of the protrusion is 6 18.It is constructed by special-shaped steel ball and its is reasonably matched with plain ball, realize the low energy consumption grinding processing of natural scoria, and the preferable effect of natural volcanic ash ground-slag weight that grinding goes out.
Description
Technical field
The utility model belongs to natural scoria grinding processing technique field more particularly to a kind of natural scoria grinding adds
The special-shaped steel ball of working platform.
Background technology
For high performance concrete, universal ripe way is adding coal ash, slag in concrete both at home and abroad at present
The active mineral admixture from industrial residue such as powder and silicon ash, to reach improve workability, delay hydration heat speed,
It reduces concrete cracking, improve durability, and reduce the purpose of cost.However on the ground for lacking these conventional mineral admixtures
Side, the application of natural volcanic ash is more universal, and natural scoria is that performance is preferably a kind of in natural volcanic ash, but natural
Scoria hardness is big, and grinding difficulty of processing is high, and the more grinding process equipment of application is ball mill currently on the market.Ball mill is
By horizontal cylinder, input and output material hollow shaft and mill first class sections composition, cylinder is the cylinder of length, and abrasive body (such as steel is housed in cylinder
Ball, steel section etc.), cylinder manufactures for steel plate, has steel liner plate to be fixed with cylinder, and abrasive body is generally steel ball, and by difference
Diameter and certain proportion are fitted into cylinder, however steel ball and steel ball matching currently on the market is all to process clinker according to grinding
Come what is determined, it is poor to be used for larger natural scoria its grinding effect of grinding workhardness.
Utility model content
In view of the defects existing in the prior art, the utility model provides a kind of special abnormity of natural scoria grinding processing
Steel ball.The plain ball of the abnormity steel ball and different-grain diameter is subjected to rational proportion, realizes the low energy consumption powder of natural scoria
Mill processing, and the natural volcanic ash ground-slag weight that grinding goes out is preferable.
Technical solution is as follows used by the utility model solves the above technical problem：
A kind of special special-shaped steel ball of natural scoria grinding processing, is made of, institute the protrusion of plain ball and attachment thereon
The quantity for stating protrusion is 6-18.
Further, the steel ball and the diameter ratio of the protrusion are 20:1—10:1.
Further, a diameter of 100mm of the plain ball, a diameter of 5mm-8mm of the protrusion.
Further, the shape of the protrusion is circle.
Further, the quantity of the protrusion is 12.
Further, the protrusion is uniformly distributed on the surface of steel ball.
The plain ball of above-mentioned special-shaped steel ball and other grain sizes is subjected to rational proportion, constitutes natural scoria grinding
Process it is special match ball, grinding processing is special to be used for two storehouse ball mills with ball, and a storehouse institute steel loading ball weight percentage is：Diameter
The special-shaped steel ball accounting of 100mm is 87%-97%, and the steel ball accounting of diameter 30mm is 3%-13%；Two storehouse institute steel loading ball weights
Percentage is：The steel ball accounting of diameter 50mm is 10%-30%, and the steel ball accounting of diameter 40mm is 35%-55%, diameter 30mm
Steel ball accounting be 20%-35%.
The special-shaped steel ball of the diameter 100mm is 87%-97% in a storehouse accounting, and accounting is preferably 93%-97%.
The steel ball of the diameter 30mm is 3%-13% in a storehouse accounting, and accounting is preferably 3%-7%.
The steel ball of the diameter 50mm is 5%-25% in two storehouse accountings, and accounting is preferably 15%-25%.
The steel ball of the diameter 40mm is 25%-55% in two storehouse accountings, and accounting is preferably 45%-55%.
The steel ball of the diameter 30mm is 10%-30% in two storehouse accountings, and accounting is preferably 25%-30%.
The special special-shaped steel ball of natural scoria grinding processing provided by the utility model, by plain ball and adheres to thereon
Protrusion composition, the quantity of the protrusion is 6-18 a.Pass through the innovative construction and knot of special-shaped steel ball provided by the utility model
Rationally matching for plain ball is closed, realizes the low energy consumption grinding processing of natural scoria, and the natural volcanic ash ground-slag body that grinding goes out
The preferable effect of quality.
Other feature and advantage of the utility model will illustrate in the following description, and partial from specification
It becomes apparent, or is understood by implementing the utility model.
