Popularizing Knowledge About Granulation and Pelletizing Machines
Time：May 08,2021
1. The feeding section primarily ensures uniform material input into the roll gap by delivering materials in a controlled,定量 manner. The screw feeder is driven by an electromagnetic speed-regulating motor, which transmits power via belt pulleys and a worm gear reducer to forcefully push the compressed material into the main feed inlet. Thanks to the constant-torque characteristics of the electromagnetic speed-regulating motor, when the material pressure generated by the screw feeder matches the required feed rate of the main machine, a stable feeding pressure is maintained, ensuring consistent pellet quality. If the feed rate becomes too high, the feeder motor may experience electrical overload; conversely, if the feed rate is too low, pellet formation will fail altogether. Therefore, skilled operational techniques are essential for maintaining the smooth and efficient operation of the pelletizing process.
The ball press machine technology boasts reliable quality, versatility, and powerful compression capabilities, making it ideal for large, medium, and small enterprises looking to establish production lines of varying scales. It is perfectly suited for forming a wide range of materials, including industrial gasifiers, boiler-grade fuels, cold-pressed briquettes, ignition coal, household coal, as well as applications in civil metallurgy, refractory materials, pharmaceuticals, and more. After years of industrial use and continuous improvement, this robust ball press machine outperforms similar products on the market, offering notable advantages such as high ball-forming efficiency, low energy consumption, and a compact design that simplifies maintenance and adjustments.
Spherical Granulation Pelletizer
The high-pressure balling machine, developed and produced using advanced technology, has been extensively refined and improved over the years. Today, it is widely used in industries such as fertilizer production, metallurgy, mining, coal processing, refractory materials, abrasives, and ceramics. This spherical granulation and pressing machine can firmly compress powdered materials like iron ore, copper ore fines, iron oxide scale, iron-containing dust sludge, silico-manganese alloy, coke powder, and coal powder into dense, block-like shapes—ready for direct smelting and application.
Constructive composition
The ball press machine consists of three main parts: the feeding section, the transmission section, and the forming section.
1. The feeding section primarily ensures uniform material input into the roll gap by delivering materials in a controlled,定量 manner. The screw feeder is driven by an electromagnetic speed-regulating motor, which transmits power via belt pulleys and a worm gear reducer to forcefully push the compressed material into the main feed inlet. Thanks to the constant-torque characteristics of the electromagnetic speed-regulating motor, when the material pressure generated by the screw feeder matches the required feed rate of the main machine, a stable feeding pressure is maintained, ensuring consistent pellet quality. If the feed rate becomes too high, the feeder motor may experience electrical overload; conversely, if the feed rate is too low, pellet formation will fail altogether. Therefore, skilled operational techniques are essential for maintaining the smooth and efficient operation of the pelletizing process.
2. In the transmission system, the main drive consists of the following components: electric motor → V-belt → gearbox → open gear → rolling rollers. The main unit is powered by an electromagnetic step-speed motor, which transmits motion via belt pulleys and a cylindrical gear reducer, ultimately driving the driven shaft through a pin-and-tube coupling. The driven shaft and the active shaft are synchronized via an open gear mechanism. Additionally, a hydraulic device is installed behind the passive bearing housing. This hydraulic protection system uses a hydraulic pump to deliver high-pressure oil into a hydraulic cylinder, causing the piston to move axially. The front connector of the piston rod is mounted on the bearing housing to ensure optimal production pressure requirements.
3. The forming section primarily refers to the main machine unit, with the roller assembly serving as its core component. When excessive material is fed between the two compression rollers or when metal blocks enter the system, the hydraulic cylinder piston rod experiences overloading pressure. In response, the hydraulic pump automatically shuts down, while the accumulator helps cushion sudden pressure fluctuations. Simultaneously, the relief valve opens to redirect excess oil back to the reservoir, and the piston rod retracts slightly, widening the gap between the rollers. This allows hard objects to pass through safely, restoring the system pressure to normal—thus protecting the rollers from damage.
Adjusting the pressure allows for flexible and responsive production, meeting the requirements for pellet density.
