Can We Produce Uniform Sized Fertilizer Granules From Compost

In general, for compost pellet making, uniform size is also a manifestation of excellent quality. But, how to produce uniform sized fertilizer granules from composting? It requires the right techniques and equipment. Whether it is before, during or after the granulation of organic compost fertilizer.

What pretreatment we can do for produce uniform sized fertilizer granules with compost?

Before feeding material into compost pellet making machine, there are two processes you can do for improving uniform size.

Crushing organic compost into fine powder

After aerobic fermentation, because of 30% moisture, there is usually some agglomerates in decomposed manure. Their large size will hamper the granulation of compost fertilizer. Therefore, it is advisable to break down organic compost into fine powder first. Here, we can offer you various compost grinders for your choice.

Mixing compost with other materials evenly

Then, when you plan to add auxiliary material for making better compost pellet, we recommend you also use a compost mixer before pelleting. Because, mixing the compost powder with additives thoroughly is key to ensuring the consistency of the ingredients.

3 Factors affects the uniform size of your compost pellets fertilizer during granulation process

During the granulation process, there are 3 main factors influence to produce uniform sized fertilizer granules. The choice of compost pellet machine, binder addition, and moisture control.

Compost pellet machine purchasing

Selecting the right compost pellet machine is the simplest method. For this, double roller press granulation has the higher granulation rate (95%) of uniform size compost granules. Because, the machine mainly makes use of mechanical press force between rollers, which has many ball socket with equal size. Instead of natural rotation. However, for those who want to make round ball shape compost, disc granulator is the best choice. Its granulation rate can reach to 93%.

Binder addition for produce uniform sized fertilizer granules

Incorporating a binder is also essential to produce uniform sized fertilizer granules from composting. Binders such as clay, starch, or natural polymers help compost particles adhere, forming consistent organic fertilizer pellets. The right binder not only aids in pellet formation but also enhances the durability and quality of your compost fertilizer pellet. So, adjusting binder type and quantity based on material properties can significantly improve size uniformity.

Control the moisture of compost granulation

Moisture content is a critical factor in the compost fertilizer granulation process. Maintaining moisture at an optimal level (usually between 20-45%) ensures that composted materials bind effectively to form into consistent size organic fertilizer pellets. Moreover, the moisture is also closely related to the final granular compost size you prepare. Generally, the less the water, the smaller the size; the much the water, the larger the size.

How to make the granulated compost more uniform after the compost pelleting?

If you need to make granulated compost more uniform, YUSHUNXIN can provide you with 2 tips.

Use a fertilizer polishing equipment

Employing fertilizer polishing equipment helps smooth and round off the edges of compost pellets. At the same time, it can enhance the uniformity and overall appearance of final compost pellets you make. You can use it after new type organic fertilizer granulator and dry extrusion compost pellet machine.

Sieving out compost granules with uniform size

After polishing, separate the compost pellets using a compost sieving machine. This step separates granules by size, ensuring only those within the desired size are retained. Resulting in uniform compost pellets for you. And the unqualified compost granules also can be returned to crush and granulate again.

You can choose the above method to produce uniform sized fertilizer granules from composting according to your needs. If you have any requirements for compost granule making, welcome to contact us immediately, we will offer you customized granulated compost solutions.
