What are the characteristics of dry powder briquetting machine molding technology?

Dry powder briquetting machines are generally used for the compression molding of dry powdery materials, and most other types of briquetting machines such as metal briquetting machines and dry powder briquetting machines generally require the addition of binders, additives and other auxiliary briquetting machines. However, the dry powder briquetting machine can be directly pressed without additives and adhesives. It can not only be cold-pressed without adhesives, but also can be hot-pressed according to the requirements of the performance and purpose of the finished ball. Speaking of raw materials, must the dry powder not contain any moisture? Let's talk about what kind of materials are not suitable for dry powder briquetting machine?

The answer is actually very simple. Since it is a dry powder briquetting machine, we can tell from the name of the briquetting machine. At this time, it is distinguished according to the material being pressed. Since it is a dry powder, if the user's material contains moisture, it is recommended that you do not choose a dry powder briquetting machine. You should choose the most suitable briquetting machine according to the specific conditions of the material. And some of the special requirements for the refined oil of the press ball must be pressed with a dry powder briquetting machine.

Dry powder briquetting machine molding technology characteristics can be molded without adhesives

The technical feature of dry powder briquetting machine molding is that it can be molded without adhesives. Generally speaking, the briquetting machine requires the use of adhesives to complete the entire compaction of the material, but the dry powder briquetting machine is not the case. The characteristic of his molding technology is that no adhesive is used in the reproduction process. , Only relying on strong molding pressure can achieve batch molding of materials.

The binder-free molding method is widely used in the processing of dry powder. Although there is no external binder, it still uses the cohesive component of the dry powder itself to complete the molding work. In addition, some dry powder factories use hot pressing to make the dry powder produce a certain degree of plasticity, and then press it into a dry powder briquetting machine, a powerful briquetting machine and other equipment, and the rollers are rotated at a constant speed to compress the material. The pressure changes from small to large, and the molding pressure reaches the maximum at the center of the pair of rollers. After the material passes the line, the molding pressure decreases rapidly, and finally the material enters the ball-off state.

We mentioned above that the forming feature of the dry powder briquetting machine is that it can be pressed without additives and binders. In addition to using the adhesive properties contained in the dry powder raw material itself, more importantly, the dry powder briquetting machine has a strong pressure, through which the pressing can be completed more easily.

In summary, the technical characteristics of the dry powder briquetting machine that can be directly pressed without using adhesives are also closely related to the strong pressure of the dry powder briquetting machine itself. Moreover, some of the more special raw materials will have some chemical reactions after adding binders or additives, which will affect the properties of the powder and the characteristics of the finished product, so a dry powder briquetting machine is required to complete the pressing work.
