Abstract
A ball grinder using the conic tetrahedals as grinding body is composed of cylinder, axle, motor, and the conic tetrahedals and circular balls in the ratio of (1-2):(1-10). Its advantages are high productivity, low loss of steel balls, and high specific surface area of powder body.
Description
Technical field:
The present invention relates to a kind of ball mill.
Background technology:
The mill ball that has now in the ball mill mostly is circular, owing to only be the some contact between the mill ball, just exists the low problem of grinding efficiency.
Summary of the invention:
The object of the present invention is to provide a kind of ball mill that can improve the use four-face pyramid grinding body of ball mill grinding efficient, it comprises cylindrical shell 1, cylindrical shell 1 is provided with axle 2, one end of axle 2 is connected with motor 4, pack into simultaneously in the cylindrical shell 1 four-face pyramid grinding body 5 and circular mill ball 6, described four-face pyramid grinding body 5 is 1: 10～2: 1 with the number ratio of circular mill ball 6.There is following advantage in ball mill of the present invention: 1. circular mill ball and four-face pyramid grinding body 5 are housed in the ball mill simultaneously, and four-face pyramid grinding body 5 just in time is filled in the natural gap of circular mill ball.Because the space reduces significantly between ball, in the grinding material process, material no longer concentrates in the space between ball and ball, but be evenly distributed in the mixed system of ball and material, so just provide more broken probability to ball, four interior concave spherical surfaces of four-face pyramid grinding body are adjacent the protruding sphere effect of cooperatively interacting of four balls simultaneously, push under the effect of external force being distributed in four materials between contact-making surface, grind, pound and smash etc., increased the broken probability of abrasive body greatly to material, thereby the unit-hour output of ball mill is increased substantially, reduced the production power consumption of powder significantly.2. the product quality and the specific area of powder have been improved: because the protruding sphere effect of cooperatively interacting of four balls that four interior concave spherical surfaces of four sides bullet are adjacent, under the effect of external force, push, grind, pound and smash etc. being distributed in four materials between contact-making surface, increased the broken probability of abrasive body greatly to material, make the particle of powder be ground into littler physical size better, the fineness of powder is reduced significantly, increased substantially the specific area of powder simultaneously.3. improved the sphericity of powder granule: because mutual extrusion, the effect of milling between interior concave spherical surface and protruding sphere, the probability that makes material form spherical powder increases greatly, therefore, can improve the sphericity and the spheroidization amount of powder granule greatly, rationally improve the physics and the chemical property of powder.4. reduce the abrasive media loss of unit powder: by four-face pyramid grinding body of the present invention and the unified efficient grinding system of setting up of common ball, the time of grinding unit mass finished product powder is shortened, reduced ball and made the time and the probability of idle work, be stranded this and greatly reduce the loss of abrasive media.Through actual tests, use product of the present invention after, can improve the unit-hour output 15～40% of ball mill, reduce grinding pow consumption 10～40%, improve the specific area 15～35% of powder, improve the spherical rate and the nodularization amount 10～25% of powder, reduce the steel ball loss more than 10%.
Description of drawings:
Fig. 1 is the structural representation of ball mill of the present invention, and Fig. 2 is the structural representation of four-face pyramid grinding body 5, and Fig. 3 is the structural representation of circular mill ball 6.
The specific embodiment:
The specific embodiment one: the ball mill of present embodiment, it comprises cylindrical shell 1, cylindrical shell 1 is provided with axle 2, one end of axle 2 is connected with motor 4, pack into simultaneously in the cylindrical shell 1 four-face pyramid grinding body 5 and circular mill ball 6, described four-face pyramid grinding body 5 is 1: 10～2: 1 with the number ratio of circular mill ball 6, the profile of described four-face pyramid grinding body 5 is a positive four sides bullet, all be provided with the sphere 5-1 of indent on four faces of four-face pyramid grinding body 5, four-face pyramid grinding body 5 noted earlier is to be formed by ceramic material.In rotation process, circular mill ball 6 rubs mutually with the interior concave spherical surface 5-1 of four-face pyramid grinding body 5, thereby product to be ground is ground.Product of the present invention and existing circular mill ball are used, and can improve the grinding efficiency of product greatly, are beneficial to and apply.
The specific embodiment two: the four-face pyramid grinding body 5 in the present embodiment is 5: 3 with the number ratio of circular mill ball 6.Described four-face pyramid grinding body 5 is to be prepared from by metal material.
The specific embodiment three: the described four-face pyramid grinding body 5 of present embodiment is 1: 1 with the number ratio of circular mill ball 6.
The specific embodiment four: the described four-face pyramid grinding body 5 of present embodiment is 1: 8 with the number ratio of circular mill ball 6.
The specific embodiment five: the described four-face pyramid grinding body 5 of present embodiment is 2: 1 with the number ratio of circular mill ball 6, make that natural gap all obtains filling between four arbitrarily adjacent circular mill balls, in the mill running process, material obtains more disintegrating machine meeting, thereby can better improve grinding efficiency.
