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. Мындан тышкары, 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
Чынында, if you use common NPK materials or certain mineral powders, it won’t cause more wear and tear on the rollers. Адатта, under standard conditions, double roller fertilizer granulator can last up to 1500 тонна of NPK granular fertilizer production. For example, карбамид, ammonium sulfate, ammonium chloride, calcium carbonate, limestone, zeolite, bentonite and other similar powder or lumps. Мындан тышкары, when extruding NPK fertilizer powder directly for granulation, you needn’t to add other auxiliary materials. Бирок, if you make compound fertilizer granules from finer mineral powder, the extrusion pressure between the two rollers alone is not enough forming. Ошондой эле, you can add 20% water appropriately for better granulation effect.
≤800 Tons of Corrosive Materials Roller Press Granulating
In general, some compound fertilizer materials are slightly acidic. When the rollers press these materials, the temperature will rise up. Ошондуктан, through certain physical and chemical reactions, these raw materials can corrode the roll coating and ball socket shape over a long period of time. Чынын айтсам, this extruder pelletizer can produce approximately 800 tons of fertilizer granules from corrosive substance. Мисалы, you can use ammonium chloride, potassium nitrate, calcium chloride, calcium nitrate, manganous sulfate, monoammonium phosphate, жана башкалар. to make fertilizer pellets. Дагы эмне, regular cleaning and maintenance can extend the service life of the roll dies.
≤500 Tons of Organic Fertilizer Granule Compact Production
Чынында, organic fertilizer granulation raw materials include chicken manure, pig manure, kitchen waste, sawdust, bean dregs, biogas residues, mushroom residues and so on. Башында, 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. Натыйжада, double roller compaction pelletizer has a maximum lifespan of processing 500 тонна of organic waste.
How to Extend The Service Life of Fertilizer Roller Granulator Machine?
Proper maintenance can significantly extend the service life of roller granulating machine. Биринчиден, regular cleaning is crucial. And you remove residues, especially when processing corrosive materials. Экинчиден, proper lubrication reduces friction and prevents the machine parts from wearing out prematurely. Кошумча, operators should avoid overloading the granulator, as excessive load can accelerate wear. Акырында, you should frequently inspect the roller skins for wear and tear. Анда, you can replace worn-out parts promptly to prevent further damage.
