Then after fertilizer granulation, you will find that there are some fertilizer granules that have a size which is larger or smaller than you require. How to treat them? Discard directly? No, what a waste! You can return them for re-granulation. But before this, you need to grind these unqualified fertilizer particles into powder again by suitable fertilizer crushing machine. In this way, there is nearly no material waste in your fertilizer production process.

When you want to make fertilizer powder after chicken manure composting, which has a high moisture content. We recommend you choose semi-wet material crusher. It can crush high water content materials without any blocking. Why? Because there is no screen inside, even materials that have just been picked up from the water can also be crushed smoothly.

Will the absence of a screen affect crushing efficiency? Absolutely not. Because our semi-wet material grinder adopts a two-stage rotor, that is, this machine will crush chicken manure compost twice. Upper rotor will break it into small particles first. Then the lower rotor will continue crushing particles into fine powder. Finally, the crushing granularity can reach 50 mesh.

Then provided we plan to dispose of cow manure into compost fertilizer powder, which fertilizer crushing machine is more suitable for it? A cow usually generates 35 kg of manure a day, which is far more than chicken. So at that time, you may need a manure shredder with a larger capacity. Here, you can choose the new type vertical crusher. Its largest output can reach 15 t/h and the inlet size is 650×450 mm.

Is it also suitable for high moisture manure fertilizer processing? Of course. This vertical fertilizer crusher is also designed without screens. And it mainly relies on crushing blades to turn cow manure compost into fine powdery fertilizer.

The above two crusher machines are both produced for crushing high water content materials, such as manure compost. However, besides animal manure, agricultural waste, such as straw, wood, etc is also commonly used materials in commercial organic fertilizer compost making. Is there a grinding machine suitable for crushing dry organic waste?

For this, we can provide you with straw pulverizing equipment. Its feeding water content is less than 10%. What’s more, there is a screen inside the straw crusher. Therefore, it can help you to crush your compost materials into smaller size particles. Then you can produce organic fertilizer pellets of a higher quality and more beautiful appearance.

Moreover, there is also professional wood waste crusher to process wood shavings, branches, wood chips into fine powder to make better organic fertilizer. Commonly, it has two material input ports. One is for log powder making. It can grind long log wood, branches, etc into fine powder fast. Another one is for crushing straw, wood shavings, etc.

Besides, according to your needs, we can replace the crushing sheet with that with stronger teeth. Then combining it with belt conveyor, it can help you thick wood log, corn cobs, etc which has a high hardness easier. So only tell us your actual requirements, we can offer you customized wood shredder.

For one thing, it adopts impact crushing method. Which makes use of high-speed rotating hard alloy chain to crush materials. So it can turn returned unqualified fertilizer pellets, which has a high hardness, into smaller size powder easily and quickly.

For another, although has a capacity of 1- 15 t/h, it only needs a small area for installation. Whether you buy vertical single chain crusher or horizontal double chain shredder. So you can setup your fertilizer making line more smoothly.
