specific Embodiment approach 1

[0005] Specific embodiment one: the ball mill of this embodiment, it comprises cylinder body 1, is provided with shaft 2 on cylinder body 1, and one end of shaft 2 is connected with motor 4, and four-sided conical grinding body 5 and circle are loaded into cylinder body 1 simultaneously. shaped grinding ball 6, the ratio of the number of the four-sided conical grinding body 5 to the circular grinding ball 6 is 1:10~2:1, the shape of the four-sided conical grinding body 5 is a regular four-sided cone, and the four-sided cone The four faces of the shaped grinding body 5 are all provided with concave spherical surfaces 5-1, and the aforementioned four-sided conical grinding body 5 is made of ceramic materials. During the rotation, the circular grinding ball 6 rubs against the concave spherical surface 5-1 of the four-sided conical grinding body 5, thereby grinding the product to be ground. The product of the invention is used in conjunction with the existing round grinding balls,...

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: [0001] The invention relates to a ball mill. Background technique: [0002] Most of the grinding balls in the existing ball mill are round, and because the grinding balls are only in point contact, there is a problem of low grinding efficiency. Invention content: [0003] The object of the present invention is to provide a ball mill using a four-sided conical grinding body that can improve the grinding efficiency of the ball mill. It includes a cylinder 1, a shaft 2 is arranged on the cylinder 1, and one end of the shaft 2 is connected to a motor 4. The four-sided conical grinding body 5 and the circular grinding ball 6 are simultaneously loaded inside, and the ratio of the number of the four-sided conical grinding body 5 to the circular grinding ball 6 is 1:10-2:1. The ball mill of the present invention has the following advantages: 1. The ball mill is equipped with circular grinding balls and four-sided conical grinding bodies 5 at the same time, and th...
