Are you looking for a project for making cow waste fertilizer in a large scale? Do you plan to start organic fertilizer production business? Rotary drum granulation production line is an ideal choice for you. Whether you want to make chicken manure fertilizer, cow waste fertilizer or pig manure fertilizer. Whether you plan to prepare low, medium or high concentration organic fertilizer. It can fully meet your needs. In addition, it has a larger capacity than other fertilizer granulation systems, and its output can reach 30t/h. This is, it can help you produce up to 200,000 tons of fertilizer pellets per year. Therefore, it is widely used in the mass production of organic fertilizer.

How to Start Cow Dung Fertilizer Production in a Large Scale?

With the increasing demand for organic fertilizer, more and more people want to invest in large organic fertilizer plants, especially cow dung fertilizer manufacturing. However, neither the disc granulation line nor the roller extrusion granulation line is suitable for the production of large-scale organic fertilizers. So we specially design the rotary drum granulation production line for you. Then what equipment is needed in this preparation project of large scale organic fertilizer?

Dewatering Machine

The manure of cattle, notably dairy cows, contains a large amount of water, about 80%. That retards the speed of composting. Hence, it is necessary to reduce its moisture to a certain amount, under 45%, before composting. You can use manure separator machine to process your fresh cattle manure first.

Cow Manure Composting Equipment

During this process, it is possible for organic materials to completely decompose and salutary microorganisms to grow. Meanwhile, a number of harmful germs,  microorganisms and parasite eggs are killed as the compost temperature rises. Thus, your cow dung is up to your national standards as a safe material to make organic fertilizer. Our moving type compost turner and windrow compost turner are good helpers for turning your compost piles.

Crushing to Cattle Waste

In order to prevent cow dung from caking, a cow dung crushing machine is indispensable, on your commercial cow dung fertilizer rotary drum granulation production line. It can evenly crush your materials into powder, facilitating you to make them into better fertilizer. Moreover, substandard fertilizer pellets require the process of crushing. Thus, it is necessary for you to equip your fertilizer production line with 2 crushers.

Rotary Screening Machine

On your cattle manure fertilizer production line, there are 2 rotary screening machines. One is for screening useless matters out of your compost, such as stones and rocks, while the other is for sifting unqualified fertilizer pellets.

Rotary Drum Granulation for Cow Dung

In commercial cattle manure production plants, the method of wet granulation is prevailing. If you prefer that method, our rotary drum granulator may make you satisfied. It is able to ensure 30 tons of cow manure fertilizer output every hour. Moreover, its rate of granulation both exceeds 95%. But the pellets made by it need further processes.

Drying and Cooling

After the process of drying, water moisture in your cattle manure fertilizer pellets is greatly decreased. However, you need a rotary cooler to cool your dried fertilizer pellets. In doing so, your fertilizer pellets can be stored for a longer time without caking.

Automatic Bagging Machine for Cattle Granules

In a commercial cattle manure rotary drum granulation fertilizer manufacturing plant, tons of output hourly asks for the consecutive process of bagging at a high speed. Our fertilizer bagging machine can realize the automatic process of weighting, packaging and sealing quickly. Hence, the need to hire more people to manually bag fertilizer is obviated, largely cutting your labour costs.

What Granulation Method Does Cow Dung Rotary Drum Pelleting Line Employ?

When you select cow dung fertilizer making system for your organic fertilizer business, you also need to focus on the technology it employs. Rotary drum granulation making line mainly adopts wet granulation method, which adds water or other adhesives to materials to improve granulation effect. During wet granulation, the steam will be injected into the rotary drum pelletizer, This steam will provide suitable temperature and humidity conditions for fertilizer granulation. Then as the action of rotary drum, the material will stick with each other and roll into round fertilizer granules. Is this over? NO. The fertilizer pellets produced by wet granulation method usually have a high moisture content. So it needs drying machine and cooling equipment to remove the redundant water.

Why Do you Choose Cattle Manure Rotary Drum Granulation Line from SX?

Rotary drum granulation line is one of the most popular products in SX. And it has earned trust from cow dung fertilizer manufacturers at home and abroad. Why? There are some reasons as follows:

Large Capacity

As mentioned above, it is the optimal option for cow dung fertilizer plant. The capacity range of it is from 5,000-200,000 tons/year. And rotary drum granulators SXZGZ-2080 and SXZGZ-3210 are specially designed for mass production of fertilizer. They can make 8-15 tons and 15-30 tons of fertilizer pellets per hour respectively.

Wide Applications

The rotary drum granulation production can manufacture organic fertilizer with different concentrations and types. Including low, medium and high concentrations of organic fertilizers. And besides cow dung fertilizer, the preparations of chicken manure fertilizer, NPK fertilizer, compound fertilizer, bio fertilizer, etc.

High Degree of Automation

The whole drum pelleting line for cattle manure fertilizer making is kept running by an electrical automated control system. So it is a fully automatic fertilizer making project. Only by employing a few workers, you can finish high quality fertilizer preparation perfectly.

Producing Higher Strength Fertilizer

Because this system makes fertilizer adopt wet granulation method. So the produced cattle waste fertilizer has a high density and strength. And this makes finished fertilizer easier to transport and store, which is not damaging these cow dung granules.

Why Can you Make Profits from Cattle Manure Fertilizer Production?

A Surge in the Number of Cattle

With the increasingly huge requirement for meat and dairy products, a growing group of commercial cow farms has appeared hither and thither. Consequently, the number of cows has reached its historical high in recent years. Because of the increasing number of cows, the amount of their dung produced one day is tremendous in a commercial farm. That brings a headache for farmers.

How much manure does a cow produce per day?

Generally speaking, within one day, a cow is able to produce more manure than other animals. For instance, the quantity of waste produced by an adult beef cow is over 30 kg per day (that produced by a dairy cow may be higher, about 60 kg per day).

A Difficulty for Disposing Cow Waste

If you have a commercial farm with thousands of cattle, the daily amount of cattle dung reaches more than 3 tons. Definitely, that is a huge pile with stink, waiting for you to deal with. You may think the number is not a big deal. But the annual amount, about 10,950 tons, may totally overwhelm you. According to our buyers, the gross payment used to dispose of the manure was about thousands of dollars a year.

Why Can Cattle Dung be Made into Fertilizer?

A Ability to Improve Soil

What’s more. it can create a benign environment for microorganisms, which greatly improves the fecundity of soil. So,it goes without saying that cow manure is a good fertilizer.

Various Nutrients for Plants

In comparison with other manure, such as chicken poop, pig waste and horse manure, cow dung contains a variety of organic matters and trace elements that are essentials for the growth of plants and crops.
