Powder Granulation Machine

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 trough 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.

Without any additives, dry powders are granulated directly.

Granular strength can be adjusted by adjusting the pressure of roller, control strength of final products.

Cycle operations to achieve continuous production.

High yield of finished products.

Materials are force to compress molding by mechanical pressure, without any additives, the product’s purity is guaranteed.

Dry powders are granulated directly without follow-up drying process, the existing production process is easy to convergence & transformation.

Granular strength is high, compared with other granulating methods, the improvement sof bulk density are significant,especially for the occasion where increase the proportion of product accumulation.

A wide range of raw materials can be used, granular strength can be freely adjusted according to different materials.

Compact structure, easy maintenance, simple operation, short process, low energy consumption, high efficiency, low failure rate.

Control environmental pollution, reduce waste and powder packaging costs, and improve product transport capacity.

Feeding device adopts frequency adjustment control, high automation ,one can control multi-machine, low labor intensity and long term continuous operation,etc.

Major transmission components use high quality alloy material. stainless steel, titanium, chromium and other surface alloys which greatly improved wear resistance, corrosion resistance, high temperature and pressure capabilities, so that this machine has one long service life.
