Effect of raw materials and process conditions of compound fertilizer on granulator
2019-12-13
What are the effects of raw materials on granulation in the NPK fertilizer production line? Let's analyze together:
The moisture of the granular raw materials is too high, and it is easy to form mutual adhesion deformation, resulting in different shapes and sizes, but also sticking to the equipment, causing the equipment to run a heavier load, will damage the equipment and cause accidents, and ultimately affect product quality and efficiency.

The effects of process conditions on granulation include: in any case, it is necessary to ensure that the strength and indicators of the granules meet national technical requirements, so that the moisture content of the main raw materials used in the compound fertilizer is not too high, and promote the high quality and high density of the cue ball as well as complete.
During the operation period of the machine in the fertilizer manufacturing process, ensure sufficient time and high pressure resistance. Minimize the excessive input of raw materials, control the moisture content, and do not add too much burden to the equipment to bear. The above all have a great impact on the granulation quality, yield and size.
The existing granulation technology in China is mainly divided into the following three types: rolling forming, mechanical force and capillary forming. The whole process is through the continuous rolling process of the granulator, through the added water or powdery materials, etc., the continuous friction and collision of the granulator equipment during rotation, such repeated formation.
Wet molding stage: This is an important core stage. It is to nucleate the powder-wrapped object and let the liquid stick to the inside of the powder raw material. When the dry solid particles come into contact with water, the surface of the particles will quickly absorb moisture to form film water, capillary water, and make the particles close together under the external surface tension or external force. They are close to each other and adhere to complete the powder forming.
Growth collision stage: This is a step-by-step integrated process that allows the particles and raw materials, particles and particles to repeatedly squeeze and collide through the equipment. During the nucleation process, due to the addition of the binder, many small particles gradually increased collisions and then bonded together to form normal particles.
Crushing and abrasion stage: This is a process in which dry or wet granules are collided or worn in the fertilizer granulator machine, and incomplete granules are processed after being squeezed. During the manufacturing process, it is easy to affect the uneven size distribution of the particles, so the binder will form two large particles, which need to be uniformly dispersed through a long process.
