How To Avoid Abrasion Of The Roller Skin On The Double Roller Extrusion Granulator?

In fertilizer production, there must be some damages on the roller skin of the double-roller pellet press granulation machine. If you apply the granulating machine more properly, you can reduce the damage of the roller skin and prolong the using time of the granulation machine. But what is the preventive measure of avoiding the roller skin wear? The followings you can refer to are the preventive measures.

The Fertilizer Raw Materials

There are some impurity substances like steel and stones which will damage the roller skin. Therefore, before granulation, you should remove the slag and useless raw materials through using the fertilizer screening machine. When granulating the raw materials with high moisture and pH, you should inspect the roller skin regularly.

The Fertilizer Feeding Speed

Because the roller skin will be damage due to the uneven force produced by the inconstant speed of feeding materials. Therefore, when you granulate the powder fertilizer with the double-roller press granulation machine, you should feed the powder fertilizer into the machine with the constant speed. In this way, there will be less granulation machine abrasion while using it.

    Wet granulation & dry granulation2022-07-05T10:18:16+08:00

    When making fertilizer granules, there are two main granulating methods: wet granulation and dry granulation. Then what method may be better for different materials? How to choose suitable machine to get high efficiency fertilizer granules?

    Difference between wet granulation and dry granulation

    Wet granulation refers to the granulating of fertilizer materials with about 30%-50% moisture content. When granulating, the materials always form into granules.Because it has the centrifugal force produced by granulating machine when working. After granulating, granules always have unsuitable moisture and temperature. In order to make sure the quality of fertilizer pellets, it’s very necessary to equip fertilizer cooling and drying machine for your fertilizer making plant.Then you can pack them for sale.

    Dry granulation is the granulating process of dry materials with moisture content about 12%-18%. Low moisture content determines the granulating process always is extruding. The final granules have uniform size and fine hardness. Moreover, pellets made by dry granulating method basically don’t need additional processes.Therefore,you can pack them directly for convenient storage and transportation.What’ more, the dry granulation has simple production process, low investment and easy operation.It is suitable for small and medium-sized fertilizer producing.

    Wet granulation machine

    In SX, we design many granulator contains rotary drum granulator, new type organic fertilizer granulator and pan granulator.They all adopts wet technology.What’s more, their granulating rates are higher than 95%. And the pellets are round shapes with diameter from 3mm-8mm.

    New type organic fertilizer granulator is the specific machine only used for making organic fertilizer pellets. Its capacity is about 1-8t/h.Therefore, it’s more suitable for small and medium size organic fertilizer production line. As for the drum granulator and pan pelletizer,they can be used in organic fertilizer granules production line and compound fertilizer granulation line.In addition,if you want a large scale production scale,the deum granulator is the first choice for you.Its production capacity is 1-20t/h.

    Dry Granulation

    Equipment used in dry granulation

    Granulator used for dry granulation in SX contains double roller granulator and flat die pelletizer.

    Roller extrusion granulator is suitable for compound fertilizer granulating plant. Because it can be used for granulating all kinds of common compound fertilizer materials. When working, the two roller sheets extrude fertilizer materials into high hardness granules.In addition, the shape and size of ball socket on the roller sheet can be customized by your requirements.You have a wide range of options for these parameters.For example,it have pillow shape,semicircle shape and walnut shape.Besides,you can choose our new flat ball shape and square bar shape.

    Unlike roller granulator, flat die pelleting machine can be used for making organic fertilizer granules. Generally,the final fertilizer pellets are cylindrical shapes with diameter between 4mm to 8mm. With a fertilizer polishing machine, you can make them into round balls.

        What is the difference between granular and powder fertilizer?Which one will be the better?2022-05-30T12:01:37+08:00

        In recent years, more and more fertilizer manufacturers have chosen to sell more granular fertilizer in the fertilizer market,not powdery npk. But why?What is the difference between granular fertilizer and powder fertilizer?In general, the particle size of the boundary is about 0.1 mm. Particles with a size of less than 0.1 mm are called powder, and the granular size is about 0.1 mm to 10 mm.The larger particles exceeding 10mm are will be caking.

        Why is the fertilizer made into granules in fertilizer manufacturing,?What are the advantages of fertilizer granules compared with powder?

        • The control of fertilizer particle size is of great significance to the storage and transportation of fertilizers. Powdered fertilizers are easy to produce dust during transportation, causing pollution and waste, while granular fertilizers are not easy to cakeand are easy to transport.
        • NPK production line will add some trace nutrients to improve the fertilizer efficiency of compound fertilizer, while powder fertilizer is easy to absorb moisture and cakeafter adding trace elements. However, the composition of granular fertilizer is stable, and it is not easy to cakeeven if trace elements are added.
        • Fertilizer granulation improves the quality of agricultural production. Fertilizer granules play the role of slow-release fertilizer effect. Itis convenient for fertilization and not easy to damage the soil.
        • Compared withpowdered fertilizers, fertilizer manufacturers choose to produce granular fertilizer can makea higher profit.In the fertilizer market, the price range of per ton granular fertilizer is 200-300$.

        Granular fertilizer are selling well in the market

        Compared with powdered fertilizers, granular fertilizers need to increase the granulation process. But granular fertilizers have more advantages in circulation, application and fertilizer efficiency, enough to offset the cost of granulation. Therefore, most of the fertilizers sold in the market are in granular form. Recently, farmyard manures and organic fertilizers such as compost and poultry manure have also been used after being granulated.

        Manufacturing granular fertilizer

        Granular fertilizer market prospect is broad. Therefore, how to manufacture fertilizer particles?Fertilizer pelleting production process includes mixing,granulating, drying, cooling and so on, so the composition of granular fertilizer production line is more elaborate. Hence you need a variety of fertilizer production equipment to equip the granular fertilizer production plant. However, the npk granulate production complicated line can get more high-quality npk fertilizer. What’ more, ShunXin’s process of manufacturing granulator npk is economical, and you can pay less money but get high benefits.Our company can provide you any solution about npk granulation plant to help you produce npk pelleting fertilizer effectively.Welcome to contact us now.
