Compost screen machine plays an important role in organic fertilizer making process. Whether powdery organic fertilizer making or granular organic fertilizer production. Because it can sieve out fertilizer you want to produce. This is greatly beneficial for quality organic fertilizer manufacturing. Here, SX compost screen machine is an ideal choice for you. According to the requirements of fertilizer manufacturers, we especially design powder and granule screening machines for your choice. If you have any other requirements, you can contact us for customization.

What can compost screen machine do for quality fertilizer making?

If you want to produce quality fertilizer from compost, it is essential to process compost with screening equipment. Why? What can it do for the manufacturing of your fertilizer?

Improving the purity of your fertilizer

In general, there still is much impurities in material after fertilizer composting. Such as small stones, cigarette butts, etc. This will affect the quality of your fertilizer. But our rotary screening machine can separate fertilizer from waste. So you can turn compost into fertilizer with a higher purity, which means higher competitiveness on the market.

Reducing materials waste in fertilizer making

Moreover, our fertilizer screener also can separate qualified fertilizer from the unqualified. Then you can return unqualified compost fertilizer to reprocess while sending qualified compost to further process it into organic fertilizer. That is, you can nearly turn all compost materials into organic fertilizer without waste!

How does rotary screening machine work to sieve your fertilizer?

After entering the rotary screening equipment, the compost material will turn and roll under the action of sieve mesh rotation. In this way, the compost fertilizer which meets the required size can pass through the sieve holes and enter the next organic fertilizer making process. But the unqualified fertilizer will be separated from and discharged through the end of the screener.

Will the material clog the screen holes in the production of fertilizer? Of course not. As mentioned above, compost will roll continuously because of the rotation and inclination of the screen mesh. So the material stuck in the sieve hole will be ejected, which will prevent the sieve hole from blocking.

What is the difference between powder and granule compost screen machines?

In the process of organic fertilizer manufacturing, in order to produce quality fertilizer, we recommend you screen compost twice. One is after crushing compost into powder and another is after turning it into pellets. According to different requirements of them, we especially design powder compost screen equipment and granule fertilizer screener. Then what is the difference between them?

Function

As the name suggests, the former is widely used in screening the crushed compost powder to remove waste. Such as small stones, cigarette butts, etc. Then the purity of the fertilizer you make will be greatly improved. But if you want to convert compost into fertilizer granule, you also need a rotary screener for fertilizer pellets. It can divide compost particles into small size, required size and large size.

Design

Because of different functions, it is also different in the designs of powder screener and pellets screening machine. Especially in discharge port designing. In general, we will equip powder compost screener with two outlets. One is for discharging waste and the other is for discharging fine compost powder. But fertilizer granule rotary screener usually has three outlets. They are respectively designed for the discharging of small fertilizer pellets, large compost granules and organic fertilizer particles you want to prepare, such as 3-5 mm (can be customized).

However, they also have many similarities. For example, they both have a screening capacity of 1-20 t/h. In addition, they are both widely applicable to sieving various solid materials with particle size less than 300 mm. What’s more, they also have characteristics of high screening efficiency, low noise, small amount of dust, long service life, less maintenance and convenient maintenance.

Why not screen fertilizer pellets after drying and cooling?

In the process of fertilizer pellet making, we generally recommend you design compost granule screening equipment after granulation and before drying and cooling. But why not screen fertilizer pellets after drying and cooling? There are two reasons:

Reducing energy consumption

Usually, during compost pellets drying and cooling, the energy consumption is closely related to the volume of granules. The smaller the compost pellet volume, the lower the energy consumption. So screening compost pellets immediately after granulation can greatly reduce energy consumption on fuel and electricity.

Making returned material easier to crush again

In addition, after rotary drying machine processing, the moisture content of fertilizer particle will decrease, so the hardness will increase. This will make it more difficult to crush the returned fertilizer pellets into fine powder. Hence, it is advisable to use fertilizer rotary screening machine before dryer and cooler.
