Due to the significant advantages of its extrusion molding process, counter double roller granulator s have been widely used in fertilizer production and processing. Generally, fertilizer extrusion granulators are more commonly used. Due to the physical characteristics of fertilizer itself, the specific gravity, roundness, and strength of granular fertilizer produced and processed meet good specifications. All of this is due to the roller skin of the extrusion granulator. This article will introduce you to the knowledge of the roller skin.
The double roller granulator is produced and processed using a process without drying at normal temperature. The production and processing capacity of our factory is 1 ton/hour, 1.5 tons/hour, 2 tons/hour, and other models and specifications, which are available for users to choose based on their needs. The machine has low investment, good effect, and good economic returns. It is crucial to ensure simple operation, safe and reliable operation, and convenient maintenance during the production process. Raw materials have a wide range of applicability, and are relatively suitable for granulation of various raw materials such as compound fertilizers, pharmaceuticals, chemicals, and ingredients. The equipment has a high granulation rate.
For a pair of double roller granulator, the pair of roller skins that interfere with its granulation effect is the one. Circular pits of the same depth are regularly scattered on the roller skin. When two circular rollers rotate directly opposite each other, the two half pits fit each other to produce a circular abrasive tool with an overall empty core. During the production and processing of fertilizer, raw materials are continuously pressed into this type of circular abrasive by the roller skin, resulting in circular particles. This type of particulate matter not only has a beautiful appearance, but also has good strength, and is not easily crushed due to bumps or stacking.
For particulate matter, it is very important to standardize the production of the circular pits on the surface of the roller skin of the roller extrusion granulator. It not only interferes with the formation of fertilizer, but also interferes with the ability of the finished fertilizer to shell. If it cannot be successfully shelled, the fertilizer will stick to the circular pits and cannot produce the finished circular particulate matter. Compared to the organic fertilizer extrusion granulator, the corrosion of fertilizer on the roller skin can cause interference due to the untimely cleaning of fertilizer on the roller skin.
Another thing about the roller skin is its material. To put it bluntly, the extrusion granulator relies on the force of extrusion to produce fertilizer, so the roller skin will suffer certain wear under the action of external forces. Generally, good roller skins are made of high-grade materials and undergo strict heat treatment processes, which greatly improves the surface hardness of the roller skin of the extrusion granulator and increases its service life.
So how long is the service life of the roller skin of a pair of double roller granulator? Different roller skin processing manufacturers have their own supply channels, with greatly different materials. Moreover, the quality of heat treatment production can also interfere with its hardness, which can also have a certain impact on the life of the roller skin. More importantly, the frequency of use. If the continuous production and processing of fertilizer, the roller skin will consume quickly, so this issue cannot be generalized.
