How Long Can A Double Roller Press Granulator Last?2024-08-21T17:32:48+08:00

On the whole, double roller granulator machine is one of the best-selling equipment in our company. Because it can produce 3-10mm pellets with multiple shape option in many industrial businesses. And it have 95% high granulation rate. Mostly, one of the most common questions our customers inquire us is that how long can a double roller press granulator last. The durability of these roller extrusion granulators is crucial for efficient dry granulation processes. In general, the main factor that influences the lifespan of double roller granulators, is the roller skins (commonly referred to as roller shells or roller dies).

How Do Different Raw Materials Affect Roller Die Lifespan?

There are several factors influencing the lifespan of roller shells of dry roller press granulator, including the type of raw materials during the extrusion granulation process. Moreover, roller molds are essential components, directly impacting the efficiency and longevity of the entire extruder granulation equipment. Here is an analysis of common raw materials and their impact on roller die longevity.

≤1500 Tons of Common NPK Powder Dry Granulation

In fact, if you use common NPK materials or certain mineral powders, it won’t cause more wear and tear on the rollers. Typically, under standard conditions, double roller fertilizer granulator can last up to 1500 tons of NPK granular fertilizer production. For example, urea, ammonium sulfate, ammonium chloride, calcium carbonate, limestone, zeolite, bentonite and other similar powder or lumps. Moreover, when extruding NPK fertilizer powder directly for granulation, you needn’t to add other auxiliary materials. However, if you make compound fertilizer granules from finer mineral powder, the extrusion pressure between the two rollers alone is not enough forming. Also, you can add 20% water appropriately for better granulation effect.

In general, some compound fertilizer materials are slightly acidic. When the rollers press these materials, the temperature will rise up. Therefore, through certain physical and chemical reactions, these raw materials can corrode the roll coating and ball socket shape over a long period of time. Honestly, this extruder pelletizer can produce approximately 800 tons of fertilizer granules from corrosive substance. For instance, you can use ammonium chloride, potassium nitrate, calcium chloride, calcium nitrate, manganous sulfate, monoammonium phosphate, etc. to make fertilizer pellets. What’s more, regular cleaning and maintenance can extend the service life of the roll dies.

≤500 Tons of Organic Fertilizer Granule Compact Production

Indeed, organic fertilizer granulation raw materials include chicken manure, pig manure, kitchen waste, sawdust, bean dregs, biogas residues, mushroom residues and so on. At the beginning, you should handle these materials by compost machines for fermentation and decomposition. After organic fertilizer composting, these materials contain 30-35% moisture content. And you’d better age to reduce water for a few days before granulation. Because organic compost has high moisture and strong stickiness, it is easy to clog and damage the roll molds. As a result, double roller compaction pelletizer has a maximum lifespan of processing 500 tons of organic waste.

    Indeed, double roller extruder granulator is always one of our hot-sale products. Besides, what is the important section of this machine for granulation efficiency. Of course, they are the rollers. Because these parts are the primary contact points where powders are pressed into uniform granules. Recently, many of our customers focus more on what is the roller sheet material we use in double roller granulators. Moreover, the material chosen for the roller sheets must exhibit outstanding strength and durability to withstand the pressure and friction of the process.

    Top 2 Metal Materials of Double Roller Sheets For Your Choice

    The roller skin is a vital component of a double roller granulator, playing a pivotal role in the organic fertilizer or compound fertilizer granulating process. As you operate this machinery, good roller skin benefits the granule production efficiency and longevity of this equipment, and the quality of the final pellets. Thus, choosing the appropriare material to make the roller sheets is our duty for customers’ actual fertilizer granulation and cost-effectiveness.

    Traditional Roller Skin Material of 20CrMoTi For Common Usage

    To be honest, most of the roller press granulators on the market use 20CrMoTi as roller sheets. Indeed, it is a GB standard structural alloy steel with high performance. Also, it’s a carburizing steel, which is usually a low-carbon steel with a carbon content of 0.17%-0.24%. The composition of 20CrMoTi includes chromium, molybdenum, and titanium. After quenching, it contributes to the roller sheets’ hardness and wear resistance, meeting intense requirements of the dry granulation process. Additionally, 20CrMnTi steel has good weldability, small deformation, and good fatigue resistance. So we can easily carve all kinds of shapes for ball socket on the roller skins according to client’s needs.  Its good hardness and toughness and can maintain roll dies non-deformation under high pressure over an extended period. Hence, we ensure that our extrusion granulators meet the rigorous demands of modern industrial applications by using 20GrMoTi.
