Description
One, technical field
Layered milling machine is to belong to the novel device of the industrial departments such as metallurgy, mine, chemical industry, pottery for the fine grinding of material wet type.
Two, background technology
The object of this development is to intend at a kind of energy-efficient New type wet atomizer mill of exploitation.Mainly ball mill, vibrating ball-mill and spiral agitator mill at industrial departments such as metallurgy, mine, chemical industry, potteries for the equipment of wet type fine grinding at present.The operation principle of these three kinds of grinding machines is basic identical, grinding charge material taking gravitational field in main stirring slip, be defeated by spherical milling medium energy by the external world, spherical milling medium produced roll, friction, extruding, impact crushing material.These three kinds of grinding machine major defects are that grinding efficiency is low, energy consumption is high.Someone carries out theory analysis to ball mill and thinks that useful work only has 30% left and right.The author think its main cause be their work technological principle on defect cause.Because slip off being easy to from the contact point of two spherical milling mediums (being the application point of power) taking gravitational field grinding charge material in main stirring slip, and be not ground to or impact, cause medium and the mutual friction of medium phase or impact, make idle work.Next is that after spherical milling medium produces one-shot work done, dump energy all disappears, and this part dump energy also becomes idle work.Movable body quality be greatly also energy consumption plateau because of one of.Except above-mentioned three kinds of wet type atomizer mills, at present in building, metallurgy, what the industrial departments such as mine were applied also has column mill and grinding mill.Column mill starts development, original name vertical mill, the patent No. beginning of the nineties in last century; ZL92235489.Its frame for movement, technical process and operation principle and the circular cone spallar of applying in current industrial production and the author's eighties of last century the mid-80 start frame for movement, technical process and the operation principle of small-scale test machine (being the Layered milling machine principle machine at development initial stage) of development very similar (or be called the two synthesis).But column mill is dry operation.Grinding mill, this is the most ancient equipment, it is that material becomes stratiform to be pulverized by rolling, but is not applied in large industrial production.For improving grinding efficiency, reducing energy consumption, develop novel wet type atomizer mill.
The theoretical foundation (or technology path) of New type wet atomizer mill development has 3 points: the one, and location ore grinding; Location ore grinding refers to that when the power producing when milling medium is applied on grinding charge material, material is difficult for sliping off.Avoid phase mutual friction or impact between milling medium.The 2nd, after milling medium work done, dump energy does not disappear.The 3rd, the quality of spattering deambulation body.Design on this basis New type wet atomizer mill; Its operation principle and technical process are: by abrasive slurries taking centrifugal force as main, under the resultant force field action of gravity, impulsive force, frictional force, slip is in the grinding machine tubular liner plate upper inside wall of vertically placing, be in the process that STATIC CORRECTION USING APPROXIMATE LAYER stream mode flows downward with the movement locus of helix, the centrifugal force punching press repeatedly that the roll forming milling medium being rotated with main shaft is produced is pulverized.Between roll forming milling medium and tubular liner plate, interaction force is by being transmitted by abrasive slurries, does not contact mutually, has avoided direct friction or impact mutually between milling medium.After the kinetic energy (inertia energy) that roll forming milling medium rotates deducts frictional resistance (effectively merit) and mechanical resistance, remaining inertia energy still remains in roller shape milling medium, realized milling medium work done after dump energy do not disappear.
Feature on according to frame for movement and technique being, novel wet type atomizer mill is named as centrifugal roll-type laminar flow ore mill, is called for short Layered milling machine.
This machine starts development from the mid-80, has successively processed the small-scale test machine (principle machine) of two Φ 300mm, and has carried out contrast test with the ball mill of the extensive use in laboratory, and energy-saving effect is more than 50%.Nineteen ninety-five-2002 year again design have processed the small-scale test machine of 660 millimeters of two Φ.In to the test of the material such as electrolytic iron, manganese, its energy consumption only reduces energy-saving effect compared with the result of the test in 10% left and right (compared with spiral agitator mill) and laboratory and differs very large.Have in addition the problem such as frame for movement and performance, therefore the patent of application on April 22nd, 1997 has also been abandoned (patent No.: ZL97.238045.0).At present the reasons for the above problems are investigated thoroughly: start inspection finds that grinding mill barrel and the liner plate rotation in former design can not effectively prevent under the high speed rotation of roll forming milling medium and powerful punching press, cause the phenomenon that is departed from grinding machine tubular liner plate inwall by abrasive slurries, in the time that treating capacity increases bed of material thickening, this phenomenon is obvious.This is the main cause that former engine efficiency is low.Improved technical scheme is definite, has redesigned and has improved rear Layered milling machine (the 5th), and this is the content of this patented invention.
Three, summary of the invention: Layered milling machine.
