Подвійний ролик гранулятор

The double roller granulator works by pressure instead of moisture. Dry, finely crushed material is fed between two counter-rotating rolls; under high pressure the particles cold-weld into a dense sheet, which is then broken by a crusher and screened into pellets of the required size. No binder is needed, no water is added and there is no drying stage — the product leaves the machine already at the moisture it will be sold at.

That dry process is a significant economic advantage. A wet granulation line's dryer is its largest energy consumer, and it also represents a large share of the capital cost. A double roller line omits the dryer, cooler and much of the dust-collection system, so both investment and running cost per tonne drop noticeably. The trade-off is a pellet derived from a pressed sheet rather than a rolled sphere, so the shape is slightly flatter and the formula must be dry and free-flowing.

New types double roller extrusion granulator for sale in our company

It is the new version of double roller extrusion granulator in our company. The function of new type one is the same as traditional one. Both of them adopt dry granulation method to produce compound fertilizer. Однак, new version has different characteristics by comparison. По -перше, we can add mixing device to the feeding inlet in order to ensure uniform feeding with uniform speed. По -друге, we can equip the main frame of the box with self cleaning device to prevent material from sticking to the roller sheet. по-третє, the adjustment of roller gap adopts step-by-step variable gear adjustment to ensure that clearance is well proportioned and the operation is convenient. Нарешті, adjusting roller sheet adopts adjusting spline inside the gear to ensure that the pair is neat and not misplaced. Словом, those strengths decide our products have high quality around the world. Отже, why not think about it?

The details of work principle of double roller granulator for sale

The motor drives triangle belt, belt pulley, and speed reducer, making the granulator machine works. The mixed materials are fed from the feeding hopper, pass through the counter-rotating rollers, and are extruded into slices under the strong extrusion force. Through the driving chain, the power is transferred from the press rollers and screened to get the required granular fertilizer. The granular fertilizer are discharged fro the outlet, while powdery materials are returned to be extruded. Then the process of granulating is finished completely.

How to operate a double roller press granulator to get high quality pellets? After you feed raw materials into the granulator, the materials will move to the two roller shafts because of the gravity. Driven by the motor and reducer, the counter-rotating roller shafts will press the materials with strong power. And the strong extrusion can shape the materials into big plates. There are many grooves in the roller sheet, and groove shapes decide the pellet shapes. Through the driving chain, the shaped plates many be send from roller sheet to the crushing room. It can crush the shaped plates into oval pellets. And the finished pellets will get out from the outlet. What benefits can you get from dry type double roller granulation machine? First of all, high quality roller press granulator at reasonable price is optional. Отже, in our company you use low consumption get best roller press granulator machine. There is no need of drying facilities in our company. Загалом, people can use vapor granulation widely in granulating while the finished dry pellets must wipe off the water by drying machine. Певною мірою, it reduces or saves the cost of making fertilizer. Висока швидкість гранулювання до 85% can help you reduce material waste and make the full use of material No pollution to environment in the whole process. Він використовує лише електроенергію, яка не забруднює навколишнє середовище. Тим часом, it reduce the pollution for some special materials Why choose our double roller granulator or choose our company as manufacturer?

Часті запитання

Do I need a binder with a double roller granulator?

Usually not. The pressure alone bonds the particles. Some formulas benefit from a very small amount of water or a dry lubricant, but the machine is specifically designed as a binder-free process, which keeps the nutrient analysis of the finished product higher.

What are the advantages of a roller granulator?

No dryer, so no drying fuel cost and no drying-related pellet breakage; no steam generation; a compact footprint; a product that leaves at sale moisture; and excellent performance with heat-sensitive raw materials such as urea and ammonium nitrate.

Which materials suit dry granulation?

Urea, ammonium sulphate, ammonium chloride, potassium chloride and sulphate, mono- and diammonium phosphate, and premixed NPK formulas. Materials that are already moist, sticky or fibrous — such as compost — need wet granulation instead.

Is pellet strength as good as a drum granulator's?

In most cases better. Pressure-formed pellets are denser than agglomerated ones, so they resist handling and transport well. The visible difference is shape: roller pellets have a slightly flatter, pressed profile rather than a perfect sphere.
