Detailed Description

The structures, proportions, and dimensions shown in the drawings and described in the specification are for understanding and reading the present disclosure, and are not intended to limit the scope of the present disclosure, which is defined in the claims, and are not essential to the skilled in the art. In addition, the terms "upper", "lower", "front", "rear" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the relative positions may be changed or adjusted without substantial technical changes.

As shown in figure 1, the invention relates to a horizontal steel ball grinder, which comprises a turntable 1 and a chassis 2 which are vertically arranged oppositely, wherein grooves for grinding steel balls are respectively arranged on the bottom surface of the turntable 1 and the top surface of the chassis 2 in corresponding positions. With reference to fig. 1-3, at least one scraper 3 is disposed on the bottom surface of the turntable 1, the scraper 3 is disposed along the radius direction of the turntable 1, the scraper 1 is close to the edge of the turntable 3, and a gap is left between the bottom surface of the scraper 1 and the chassis 2, the height of the gap is generally 2-5mm, so as to avoid generating resistance to the rotation of the turntable 1 due to complete contact. When processing the steel ball, grinding fluid can enter into and flow into between carousel 1 and the chassis 2, and scraper blade 3 plays two aspects effects, plays to mix the grinding fluid on the one hand, lets the grinding fluid effectively contact with the steel ball, also prevents simultaneously that the metal particle from deposiing, and on the other hand plays the effect of striking off the metal particle that has deposiing, avoids it to deposit too much and causes adverse effect to the processingquality of steel ball. As shown in fig. 1, the blade 3 is positioned above the liquid discharge port 21 of the chassis 2.
