Which granulator is suitable for making your own fertilizer?
How to regulate fertilizer pellet size when using disc granulation machine?
Disc granulator is an ideal choice for economical small scale fertilizer pellets making. It can fully meet your requirements for 1-8 mm granular fertilizer production. In general, you can control the particle size by 2 ways.
Adjust the moisture content
The higher moisture content, the larger size; the lower moisture content, the smaller size. Why? The high water content makes materials easier to stick to each other and combine with more materials. So it is easier to roll into larger fertilizer granules.
Change the angle of disc
The sharp slope, the smaller size; the slower slope, the large size. However, what you need to focus on is that it is advisable to keep the angle of disc between 35° and 55°.
How to adjust fertilizer particle size when using rotary drum granulator, new type organic fertilizer pelletizer and rotary drum churning granulation equipment?
As for rotary drum granulator, new type organic fertilizer pelletizer and rotary drum churning granulation equipment, you also can regulate fertilizer pellet size by controlling water content. In addition, it is also an excellent choice to adjustthe rotating speed of drum or stirring shaft.
Adjust the water content
The higher water content, the larger size; the lower water content, the smaller size. But during granulation, the water content must be kept between 20% and 45%. This is the optimum moisture content for fertilizer pellet making.
Change the rotating speed of drum or stirring shaft
The higher rotating speed, the smaller size; the lower rotating speed, the larger size.
