pelletizing. Pelletizing–the forming of spheri-cal or spheroidal pellets–occurs in a rotating disc. Pelletizing principles involve the following se-quential steps: 1. Fine raw material is continually …
The advantage of this approach over disk pelletizers is that the process never stalls or comes to a standstill even if there are fluctuations in the amounts of solids or liquids added. Drums are …
The following is an overview of a typical potash pelletizing process. Potash pelletization is a reliable and beneficial method of processing potash. The following is an overview of a typical potash pelletizing process. ... After conditioning, the potash material is fed onto the disc pelletizer (pan granulator). Using tumble growth agglomeration ...
The process of pelletizing iron ore on disc pelletizers is mathematically modeled. Different methods of regression analysis are used to describe the pelletizing operation, and the equations that are obtained are compared with one another. The objective function is optimized based on the yield of green pellets of the class (–14+5) mm.
3; the load on the pelletizing disc X 4; the rotary speed of the disc X 5. The angle of inclination of the pelletizer is assumed to be constant, since no real-time changes are made to this parameter under production conditions. The granulometric composition of the green pellets can be determined from the equation that describes the opera-
The disc pelletizer, or pan granulator, is the device of choice for processing powdered bulk solids and fines into rounded, dust-free granules, improving handling and transportation qualities, enhancing performance, and creating a premium product.. As with most process equipment, choosing the right manufacturer can quickly become overwhelming. Here are a few …
The document discusses the pelletizing process which involves conditioning materials through mixing, forming pellets using a disc pelletizer or drum, and drying the pellets using a rotary or fluidized bed dryer. Pelletizing is …
Disc Pelletizer. The Mars Mineral Disc Pelletizer is an adjustable pan device utilized in micro-pelletizing, pelletizing and conditioning applications in which a shallow pan and a smaller retained burden are desired. It can be used to pelletize materials such as taconites, copper, nickel, lead and zinc concentrates.
Figure 3 schematically shows a laboratory disc pelletizer. The balling disc basically consists of a pan with a peripheral wall, which rotates with a certain inclination to the horizontal [1].
The values of speed and slope of pelletizer are derived from a theoretical equation based on the equilibrium condition for gravitational and centrifugal force acting on an individual pellet during the pelletization process (Baykal and Doven, 2000, Jaroslav and Ruzickova, 1998) for the given diameter of the disc used and based on observations ...

Disc pelletizers are a "tumble growth" or agitation agglomeration device, meaning they rely on a liquid binder and motion to form and refine agglomerates. The disc pelletizer may be used alone, or in combination with a mixer, most often apin mixer. Material is continuously fed …
The balling equipment that can be either a disc or a drum produces green pellets in a variable size distribution. 3.1. Balling disc or disc pelletizer Figure 3 schematically shows a laboratory disc pelletizer. The balling disc basically consists of a pan with a peripheral wall, which rotates with a certain inclination to the horizontal [1]. In
Local and accurate pelletizing disc control through operators control system; ... Process. Pelletizing discs are used in the agglomeration process to form fine iron ore into uniform green iron ore pellets. Green pellets are fed to a travelling …
2) After pre-conditioning, the material moves on to the disc pelletizer. For those that do not pre-condition, this is where the pelletization process begins. Here, material is continually fed to the disc pelletizer and wetted by a liquid binder spray. The disc's rotation causes the wetted fines to form small, seed-type particles (nucleation).
Process training for pelletizing plants. Proper training provides equipment operators with the ability to maximize production and product quality, avoid downtime and prolong equipment life, making it an essential aspect of …
A high quality disc pelletizer, or pan granulator, is an ideal agglomeration solution when creating a uniform pellet from dry or slightly moist materials. ... These options are customizable and differ based on material and process application considerations. Variable Frequency Drive. The variable frequency drive allows for adjustments to the ...
The disc pelletizer is a device for making green pellets in the pelletizing process. When the disk rotates around the central axis (or center line), the balled material rolls down the bottom of the disk, and the fine-grained material is scattered on the wet surface of the cue ball, so that the cue ball continues to grow to the specified size.
It is critical that the pelletizer plows are all installed at the same offset from the pan bed to ensure a flat and even surface for the pelletizing process. Worn scrapers should be replaced as needed, as they can allow …
The pelletizing process on a disc pelletizer. Step Three: Dry Wet Pellets. Once pellets reach the desired size, they are automatically ejected from the disc pelletizer via centrifugal force. From here, they are carried via conveyor or bucket elevator to the dryer. Not all operations require a drying step; in some cases the pellets will be fed ...
Keywords: Balling disc, pelletizer, balls - pellets, glomerates, vernier caliper. I. INTRODUCTION A balling disc machine also known as pelletizing ... The Marking out process The first stage …
The granulating disc processed with unique technology and 90% pellets diameters are between 3mm to 5mm. Disc granulating machine is friendly to the environment. It adopts wet granulation method, reducing the dust pollution. …
Pelletizing is carried out using either a disc pelletizer or rotary drum, with disc pelletizers (also known as pan granulators) ... so it need not be done on the pelletizer, a process which can be lengthy. Because of this, the use of a mixer prior to the …
PROCESS EQUIPMENT AVAILABLE FOR TESTING. From testing on a single piece of equipment, to a continuous process loop, we offer a variety of equipment types, as well as support equipment to cover the full range of process testing needs. ... Disc pelletizer training is a commonly overlooked, but essential aspect to a successful pelletizing ...
During the pursuit of an effective non-pressure agglomeration solution, the choice between a rotary drum and a disc pelletizer (also known as a pan granulator) often arises. To help determine the best equipment for your material and process, the following should be taken into consideration: recycle, throughput, and maintenance.
A high quality disc pelletizer, or pan granulator, is an ideal agglomeration solution when creating a uniform pellet from dry or slightly moist materials. ... This includes feasibility testing and …
The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process with a special focus on binders. ... in this case using a disc pelletizer, and the induration step. Figure 2. Typical pellet plant using disc pelletizer as balling technology. Source ...
The pelletizer offers several variables, all of which can be adjusted, and work together to create the desired pellet. How Disc Pelletizers Work. Material is fed onto the pan, where it is taken up by the rotation of the pan. Both material feedstock and a binder are continuously fed onto the disc pelletizer, making this a continuous process.
1. Introduction. Disc pelletizers are widely used in pharmaceutical, chemical and steel industries [1].During pelletization, the collision, extrusion and shear-strain effect among granules in mixing procedure in disc pelletizer plays a dominant role in particle size distribution (PSD) and mechanical properties of the products, for instance, hardness, compression …
The disc(or the disk) of Fertilizer disc pelletizer is designed to be a holistic circle-arc, with a rim to hold the tumbling pellets. The linings in the disc are high-duty glass reinforced plastics. They make the pan durable and corrosion-proof. The bottom of the disc is very firm and durable, as we reinforce it with multiple radiant steel plates.
