The ring die machine is characterised by high output, beautiful pellet shape and high density. No additives are required for pelletizing. The wear balance of the roller ring die reduces the wear and tear of the easy to wear. The ring die pelletizer is a great helper for pressing concentrated feeds, with a high output and low power consumption that is unmatched by flat die pelletizers. Due to the slower speed than the ring die pellet maker, the output of the flat die pellet maker is smaller than that of the ring die pellet maker and due to the excessive pressure and fine material density, the ring die pellet maker can squash more efficiently than the die pellet maker. There are advantages flat die machine has the advantage of low energy consumption, good mobility, suitable for small family workshops, but not for large factory enterprises. In addition, the structure of the flat die pelletizer has the advantage of less wear and tear, but the output is relatively small, usually between 300-3000 kg. So if you want to do more than 3 tonnes on one machine, you can opt for a ring die pelletizer. This is ideal for pelletizing maize straw, which is easy to press. The disadvantages are low yield, low pressure, difficulty in vacuuming and poor formability. If the working surface is widened, the balance of wear between the press rollers and the die is lost and the output does not increase. The accessories are troublesome to dismantle and install, and maintenance is troublesome. Secondly, the ring die granulator uses mechanical feeding, high speed rotating centrifugal distribution into the granulation chamber, the material is distributed through the scraper, making the feeding uneven; using the material self-weight vertical pressure chamber, feeding evenly. The size of the ring forming wheel is limited by the diameter of the die, whereas the flat die is not, allowing more carrying space. The ring die granulator rotates at high speed and has a high breakage rate of the discharge material. Flat die granulators are low speed and have a relatively low breakage rate. The ring die pellet mechanism produces materials that are difficult to shape and is suitable for materials such as wood chips, straw and grass flour; easy to shape. , corn, etc.
