4 Steps to make fertilizer for double roller press granulator production line

The double-roll granulation production line adopts the dry granulation process, which has high production efficiency, no waste water and waste gas discharge. The wide range of granulation favor through fertilizer manufacturers. If you want to know more details, please read on.

  • First, you need to compost the material.You can ferment and decompose the material . And the temperature rises rapidly to reach the required state of fertilizer making.

  • Secondly, you can crush the bulk materials. This increases productivity and reduces unnecessary operations.

  • Then, the material is divided into four pairs of roller extrusion granulators by the distributor to start granulation.

  • Finally, you need to screen after granulation. Screening out the finished products with consistent particle size for packaging. You can send the remaining residual products to the distributor again through the belt conveyor for subsequent granulation.

The overall production process of the fertilizer production plant is like this. If you still have questions, you can come to consult.

Design for making fertilizer in double roller granulator plant

Some customers will choose and match the equipment in the production line according to the actual site environment and process plan. For example, if the raw material has a high moisture content, you can add a dryer before the front-end mixer to treat the moisture content of the material to an extrudable level.

In addition, if the site is large enough, the bucket elevator can replace through a conveyor. We will conduct site planning, workshop design, equipment customization, installation training, after-sales service for customers. And delivering a one-stop comprehensive double-roll extrusion granulation production line.

How to prolong the service life of the roller granulator production line?

The use of the double roller press granulator production line has a certain life span. If you do not find and repaire in time, it will greatly reduce the production efficiency of the entire production line. Below I will detail possible problems and solutions.

For the double-roll extrusion granulation production line, its main equipment is the double-roll extrusion granulator. If there is a problem with this equipment, it will affect the entire production line.

After long-term use of the double-roll extrusion granulator, the surface of the roller skin will be worn or damaged due to the high pressure of the roller skin and the corrosion of the material. The surface of the roller skin is uneven after being worn. The semicircular ball socket gradually becomes shallow and flat. The distance between the two roller skins will also increase, and the compaction effect will become poor.Therefore, if the equipment has a long service life, you need to check the state of the roller skin regularly. Especially when you are not use it for a long time,you need to clean the surface of the roller skin. And then you can brush with waste engine oil to prevent the surface from rusting.

In addition, for the roller extrusion granulator, there is also the problem of demoulding. If the demoulding is not good, the material will stick to the roller skin, which will affect the particle forming and reduce the life of the whole machine. (Tips:The method of demoulding can be to use sawdust and a small amount of yellow sand to continuously squeeze between the roller skins until the surface of the roller skin is smooth and shiny. So that every time you can use the material. It can be demoulded smoothly and form high-quality finished granules. )

Not only the main equipment needs maintenance, but also you need to replace the vulnerable parts of other equipment regularly during the maintenance process. If you are not replace them in time, it will not only reduce the granulation efficiency, but also affect the service life of the equipment.

Therefore, improving the service life of related equipment will increase the service life of the entire production line.

Technology of roller compaction granulation production line

The double-roll granulation production line involves two aspects of process skills, please refer to the following introduction for details.

For the production of organic fertilizers, the materials you need to compost the materials in the early stage. In order to quickly heat up and decompose after composting, you can use an organic fertilizer fermentation tank for aerobic fermentation. 7 days can reach 50-60% moisture.

For the subsequent granulation stage, you can use a double-roll granulator. Using the dry granulation process can reduce the consumption of drying in the later stage and improve the efficiency.

These two processes play a huge role in the production line, making the quality of the produced particles better.

What are the benefits of using potassium sulfate as a raw material for granulation in a double-roll extrusion granulation line?

In a standard double-roll extrusion granulator production line, it is inevitable that there will be material return. Due to the characteristics of this kind of granulator – no drying extrusion granulation, the returned dry powder can easily form granules again. The molding rate of the powder with potassium sulfate added and returned after extrusion is improved, and the strength will also increase with the mixing of the sieved powder.

Because the sifted powder is extruded once, the particle size composition is different from the raw material particle size composition. There are more fine-grained materials that can fill the gaps between raw material particles during extrusion molding, so that the particle forming rate increases and the strength increases slightly. From this point of view, the secondary extrusion effect of potassium sulfate powder is better.

Of course, dry granulation is not completely free of moisture. Excessively low moisture will reduce the molding rate of potassium sulfate extrusion granulation. Excessively high moisture will not only cause too much potassium sulfate to stick to the roller skin and make demoulding impossible, but also increase the energy consumption of the post-drying process.

Therefore, the optimal moisture content of potassium sulfate powder is 1.2%,which leads to the highest particle forming rate and the best strength. This makes the pellets produced by the final production line of high quality.

Quotation for roller granulator production line

What customers care most about the production line is the price. But how to get a quotation for a double-roll granulation line? It is necessary to start with raw materials, output and equipment. Understand these clearly and get relevant data to determine the price.

double roller granulation production plant

We need to determine what raw materials you use to make the fertilizer. Because it is necessary to determine the compatibility with the double-roll granulator. It can only be produced if it meets the conditions. You need to understang the yield. We can calculate the quantity of equipment needed according to the size of the output.So that we can better meet the requirements of yours.

This is the key, directly understanding the needs of yours. According to your required equipment , we can give you the quotation.

After understanding the above, we can give a specific price. A double-roll granulator is about 2888$ – 6000$.The double-roll granulation production line needs 30,000-200,000 US dollars.

The above is the quotation of the entire double-roll granulation production line. If you need, you can come to consult.
