Our photo this week shows a rotary ore agglomerator preparing for shipment. The drum, weighing in at around 55 Tons, is being lifted by a crane onto a base while it awaits shipment. Ore agglomerators are used in heap leaching processes around the world for …
Our photo this week shows the interior of a rotary drum with a rubber liner installed. Flexible rubber liners are often used in rotary drums to help prevent buildup caused by material sticking to itself and the sides of the drum. Rubber liners are used …
Non-pressure agglomeration, also known as tumble growth agglomeration, is a process which uses a tumbling motion and binding agent to grow material fines or powders into a spherical pellet form. Non-pressure agglomeration methods include: Pelletizing (rotary drum or disc pelletizer): a process where material fines …
As a booming global population and emerging economies put pressure on existing resources, and high grade ores become a thing of the past, mining companies are looking for technologies that will allow them to economically recover target materials, namely metals, from low-grade ore sources. One …
Today’s photo shows the gear mesh of a gear and pinion drive, the mechanism that causes a rotary drum to rotate. The face of the teeth here are worn, an indication that the gear should be replaced, or they may break off. In most cases, replacement …
This week’s photo highlights a girth gear run-out procedure in action. A black strap (pictured) is mounted along the gear’s teeth. A dial indicator follows the strap’s path, and measures the tip of the teeth along the strap. This procedure reveals the amount of wear …
Pelletizer plant process audits provide a valuable tool to plant managers struggling with changes in production, under-performance, yield, and more; even for those pelletizing plants performing well, a process audit can reveal inefficiencies that when corrected, can significantly add to the bottom line. The following …
Conditioning is an important part in bulk solids processing, allowing producers to alter the material to fit their unique needs. While there are many reasons to condition a material, three central objectives are highlighted below. To improve the efficiency of the process. Conditioning a material …
The roofing granule industry is projected to grow in tandem with demand for asphalt shingles in the coming years as consumers face an increase in extreme weather events, more stringent regulations, and aging homes. As a result of the aggressive nature of the materials being …
This week’s photo highlights a ball and tube knocking system. Knocking systems are often implemented to combat build-up inside of a rotary dryer. The systems are usually externally fitted on the inlet end of the dryer, where the incoming material is most wet and sticky. …
