Embodiment Construction

[0028] refer to Figure 1 to Figure 4 The embodiment of the production process of the scaly metal powder of the present invention will be further described.

[0029] The cylindrical ball mill 1 is provided with steel balls 11 (it should be noted here that the ratio of the total mass of the steel balls 11 to the total mass of the powder is 1:8 to 1:10) and 8 to 12 Lifting bars 12, the lifting bars 12 are distributed in a uniform circumferential structure, and the steel balls 11 are placed between the two lifting bars 12. Due to the rotation of the cylindrical ball mill 1 (it should be noted here that the cylindrical ball mill The rotational speed of the cylindrical ball mill 1 is adjustable, and its adjustment is adjusted by the frequency converter 2, which can change the rotational speed of the cylindrical ball mill 1 according to the particle size and production specifications of the metal powder, so as to achieve the crushing and grinding capacity conversion), the steel bal...

Abstract

The invention discloses a flaky metal powder production process, which is used for producing metal powder in a uniform shape by means of simple procedures. The technical scheme of the flaky metal powder production process mainly includes that the procedures sequentially include material selecting, crushing, grinding, classifying and collecting in an environment at the temperature lower than 50 DEG C, both the crushing procedure and the grinding procedure are completed in a cylindrical ball mill by a dry powder ball-milling method, and grinding aids are added in the grinding procedure. The ball mill used in the flaky metal powder production process is cylindrical so that produced metal powder in more uniform in shape, the ball mill is used for dry powder ball-milling, and a drying step in wet ball-milling is omitted so that the procedures are simpler.

Description

technical field [0001] The invention relates to the technical field of a metal powder production process, in particular to a production process of scaly metal powder used in the fields of fabric gold printing, paper coating, textile printing and handicraft coating. Background technique [0002] The copper-gold powder production process in the prior art uses an octagonal cylinder ball mill to carry out the crushing and grinding process. The steel ball movement in this ball mill is impact-type, and the force when contacting the powder is large, and it is easy to crush the metal flakes. , cannot form a standardized scale-like structure, and the water surface coverage index of the powder is low. [0003] The Chinese patent application number 01103176.X discloses a production process of scaly metal powder, which consists of several processes of material selection, grinding, sorting, filtering, drying, powder sieving, secondary drying, and packaging. The material selection proces...
