A uniform heating device suitable for planetary ball mill

Abstract

The invention relates to a uniform heating device suitable for a planetary ball mill. An insulating slip ring is arranged around a main rotary disc on a base of the planetary ball mill, annular conductive copper strips are arranged on the inner ring of the insulating slip ring, and the annular conductive copper strips are connected with a power source through a slip ring connecting terminal; ballmill tanks are sleeved with heating sleeves, the bottoms of the heating sleeves are fixedly connected with the main rotary disc through annular insulating parts, a plurality of heating resistors are evenly arranged on the inner walls of the heating sleeves, and the heating resistors are connected with heating sleeve connecting terminals; at least one carbon brush box, corresponding to the number of the ball mill tanks, is fixed along the edge of the main rotary disc, carbon brushes are installed in the carbon brush boxes, one ends of the carbon brushes are connected with the carbon brush boxesthrough springs, and the other ends of the carbon brushes protrude out of the carbon brush boxes and are connected with the annular conductive copper strips; the heating sleeve connecting terminals are connected with wires of the corresponding carbon brushes. By adopting the uniform heating device, the problem that materials in ball mill tanks of an existing planetary ball mill cannot be heated during the running process can be solved.

Description

technical field [0001] The invention relates to the field of processing and grinding, in particular to a uniform heating device suitable for planetary ball mills. Background technique [0002] The planetary ball mill is an essential equipment in the grinding field. It can mix, grind and prepare samples in small batches. It is widely used in industrial production and laboratory research. However, the existing planetary ball mill lacks a suitable heating device, and it is difficult to evenly heat the materials in the ball mill tank during the operation of the planetary ball mill. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a uniform heating device suitable for planetary ball mills, which solves the problem that the materials in the ball mill tank cannot be heated during the operation of the planetary ball mill, and at the same time ensures Safe, reliable and stable ...
