Description

The nano powder of a kind of controlled stirring and vibration prepares ball mill
Technical field
The utility model belongs to powder preparation ball mill technical field, and the nano powder being specifically related to a kind of controlled stirring and vibration prepares ball mill.
Background technology
Ball mill is when material is processed or after being crushed to certain size, then carries out processing or be crushed to smaller szie key equipment used.Its uses the rotation of self or the stirring action of shaft to drive the abrasive body in its fuselage drum stir material and grind, and constantly to impact and rubs, material is worn into the fine powder of ideal dimensions through abrasive body to material.Ball mill is widely used at cement, chemical industry, building, chemical fertilizer, refractory material, china industry etc.
Ball mill can be divided into polytype, and common industrial ball mill is horizontal large-size ball mill.It is by the long cylindrical shell of level, and input and output material axle and bistrique part composition, cylinder is built with abrasive body, and cylindrical shell is generally manufactured by steel plate, and the abrasive body in cylinder is generally steelie, grinds during grinding according to putting into cylinder with material based on certain ratio.The diameter of steel ball is decided by the target size of final material.When ball mill cylinder starts to rotate time, abrasive body and material are taken to certain altitude by cylindrical shell due to the effect of inertia, centrifugal force and frictional force.When they are subject to Action of Gravity Field, both are all left, and the abrasive body of whereabouts mutually collides with the abrasive body being in cylinder body bottom and smashes material.
Laboratory ball mill is relatively little by contrast with industrial ball mills dimensionally, but roughly the same in the principle of polishing material.Laboratory ball mill is broadly divided into horizontal and vertical two types.Horizontal laboratory ball mill operation principle and industrial horizontal ball mill basically identical, drive the abrasive body in cylinder to impact material by the rotation of cylindrical shell and polish.And vertical laboratory ball mill to be turning effort by stretching into the shaft in cylinder drive the abrasive body in cylindrical shell grind material and pulverize.
According to the physics of material and the difference of chemical property, the abrasive body selected by ball mill is also different.The material of abrasive body generally can be divided into metal and nonmetal two large types.Common metal grinding body has stainless shot, wolfram steel pearl and evanohm steel ball etc.Metal material abrasive body is one of modal abrasive body, and its cost performance improves the popularity of its application.But due to the relation of self property, metal grinding body can produce a series of chemical reaction with material in process of lapping, to such an extent as to contaminated material.So when being applied to the material that grinding can react with metal, non-metal grinding body is generally selected as first.Common non-metal grinding body is made up of ceramic material majority.Such as aluminium oxide, carborundum etc.Goose common at ordinary times warms up stone and marble also can be used as abrasive body for ball mill.As the abrasive body of grinding material, itself intensity is first factor that will consider.If the material self-strength ground is larger, then need to select larger than the intensity of material own, or the abrasive body of identical material grind it and pulverize.One is the operating efficiency that can keep ball mill, and two is can not pollute material in process of lapping.Such as carbofrax material and carborundum abrasive body.
For the diameter of material after final grinding, be decided by the condition of abrasive body and ball mill self.The rotating speed of ball mill self can control frequency and the intensity of collision mutually between abrasive body.Rotating speed is higher, collision frequency and intensity larger, material diameter is then less.Equally, the diameter of abrasive body itself also directly determine material grinding after size.Abrasive body diameter is less, and after material is polished, diameter is also less.When adding the time of ball milling, the polished frequency of material also increases simultaneously, then material be polished after size also less.
There is the low shortcoming of grinding efficiency in existing ball mill.
