Product Description

Magnesite mineral dry powder granulating machine

        Our company  offers a wide range of machine sizes for high pressure granulating, which covers nearly all requirements of the clients.If your production is low,you can choose small type machine, if you have high production, you can choose one or more sets of machines according to your requirements.And certainly the process of granulating is dry.


Working principle:  
      Raw materials are sent into hopper by quantitative feeder, compactors use the pair of roller with the hole roll,leaving certain gap and rotation with the same speed reversely. Shaft holders of one group of rolls are fixed, and the other one of group can slide to help the hydraulic cylinder press the rolls for abutting closely against each other. Many arc grooves with the same shape and size are arrayed regularly on the roll surface. In accordance with different compressing ratios of target materials, the wave though of arc groove of one roll shall be directed at that of one roll. When two rolls parallel each other horizontally, powder grained materials are, continuously and evenly fed in the gap between two rolls by means of their gravities and through a forced charger from above of two rolls. After entering the nip area, the materials are gradually nipped by the rolls. With continuous rotation of the rolls, the space that the materials occupy reduces gradually and is compressed step by step and reaches the maximum shaping pressure. And then, as the pressure reduces gradually later, pressed blocks drop off the arc grooves of the rolls for recovered elasticity and gravity of the flaking machine and enter a crushing device for crushing and then enter a sieving device for sieving. At last, grained products are obtained. The powder materials and large particles which are substandard will return to bucket elevator and enter into the next process with new products.
