Description

Adjustable double-roller ball press

Technical Field

The utility model relates to a ball machine is pressed to cold pressing pelletizing processing technology field, in particular to adjustable double roll formula.

Background

In the production of cold-pressed pellets, the ball press is mainly used for pressing powdery materials which are difficult to form, such as various powders and waste materials of coal powder, iron powder, aluminum powder, slag and the like, the powder materials are fed into a roller of a roll-type high-pressure ball press through a feeder to be rolled, and because a plurality of ball sockets are manufactured on the surface of the roller, the mixture can be pressed into pellets after passing through the roller. The finished balls manufactured and molded by the ball press machine have high strength, are convenient to transport, are energy-saving and environment-friendly, improve the utilization rate of waste materials, and have good economic and social benefits. The main structure of the ball press comprises a feeding part, a transmission part and a forming part. Wherein, the feeding part mainly realizes quantitative feeding to ensure that the materials uniformly enter between the pair rollers; the transmission part generally consists of a motor, a triangular belt, a speed reducer, an open gear and a press roller; the molding part mainly refers to a main machine part, and the core part is a press roll.
