Apart from processing steel slag, it can also be used to briquette lime powder, fluorspar, iron oxide powder, dusting ash and so on. All in all, high-pressure briquette making machines play an important role in …

precondition for successful roller press operation. There- fore, this option was rejected as unfeasible. The grinding of the feed material for the ball mills by a roller press was not considered feasible either, because the moisture content in the feed was too high (>10 wt. 0/0). Suitable proved the grinding of the filter cake dewatered to 10 ...

The Bepex Roll Compactor is a high-pressure agglomerator, able to press fine and often highly aerated solids into larger, cohesive masses with controlled densities. Agglomeration is performed by compressing fine material between two opposed, counter-rotating rolls held under pressure.
