Abstract: An equipment for making abrasive particles in even distribution, array pattern and preferred orientation comprises an adsorbing releasing apparatus being composed of a plurality of acicular soft magnetic metallic sticks, an upper and a lower stators, and a plurality of windings. Each winding forms an electric circuit through a electrical source, a resistance, and a switch a plurality of blind holes being distributed on face of the blind hole feeding tropism board. Using electric current to form magnetic field for the acicular soft magnetic metallic sticks absorb or release abrasive particles plated with soft magnetic materials. The equipment is simple, convenient in operation, high in efficiency and reliability. The equipment makes abrasive particles in matrix with an ideal state in distributing density, uniformity, arrange, and tropism. Thereby, the function of the abrasive materials is fully exerted and the life of products is prolonged.

Jiangsu Tianyi Micro Metal Powder Co., Ltd.
Abstract: This invention relates to a preparation method and equipment of graphite and catalyst composite for a kind of synthetic diamond. Firstly, graphite particles shall be placed into the heating chamber for pre-heating; secondly, the heated graphite particle will be fed into the coating room with vibrator or agitator and steam of carbonyl metal complex is input for coating; finally, the coated graphite particles are fed into a cooling and passivation room for cooling and passivation of the discharging materials or enter a next round of heating and coating. The surface of each graphite particle is plated with metal layer which can promote the crystal nucleus growing into perfect diamond crystal.
