The roller briquetting press is a kind of briquetting machine that is widely used in the industry area today. Those powdery materials and waste, which need to be used in the furnace; those fuel materials, which need to be formed together to get a better heating effect, and other materials, which need to be used as a shape like ball or pillow with certain size, etc. all need the roller briquetting press to take the briquetting work.
In this roller pressing area, there are two same pressing rollers with ball-pockets on the surface, which rotate at a constant but opposite speed. When the material enters the bite angle between the two rollers, it is gradually compressed as the bite angle is reduced. At the moment when the two ball-pockets coincide, the briquetting pressure reaches a maximum and briquette is made. then, the two ball-pockets are opened and the briquette begins to elastically expand and fall off.
But not all kinds of materials need to add binder to make the briquette. Some materials have its own inherent binding properties. When we are working under the proper conditions, suitable moisture, suitable pressure, suitable briquette size, suitably designed plant, etc., it will be suitable to make the briquette without binder.
But most of the materials need to add binder to the briquetting process, add binder not only reduce the pressure required on the briquetting process, but also improve the characteristics of the briquette.
Force feeder is used as a homogenization and initial material compaction as well as overcoming the resistance of flow caused by damming in the outlet. It provides beneficial effects of an increase in material pressure, an increase in the compaction degree, and ensuring the uniformity of the flow, is a means of metering, deaerating and pre-compacting material. It guarantees stable product quality as well as increased briquetting efficiency.
It is also used as a safety device when the material is pressed into the gap of the rollers. The electronic control system will control the hydraulic system to prevent the rollers from damage when overloaded or blocked.
