Copper is a versatile metal used in many of the products that modern civilization relies on, from electronics to infrastructure. For decades, smelting has been the primary approach to copper extraction. Although this method has proven to be effective for high grade sulfide ores, it …
This week’s photo highlights a rotary dryer’s direct drive assembly, the arrangement which causes the drum to rotate. The direct drive assembly is ideal for small to medium size drums running up to 75 horsepower. Here’s how it looks: A shaft is mounted to a …
Retention time, also called residence time, is the amount of time that the material must be processed in the rotary dryer in order to achieve the desired results. The retention time required for a given application is determined through balancing the necessary process parameters – …
When looking for versatile manufacturing equipment capable of producing granules, rotary drums are often the equipment of choice. However, confusion frequently arises in choosing between an agglomerator and granulator. Because rotary drums are flexible in design and capable of processing large capacities, they are extensively …
This week’s highlighted resource is a project profile on a gold ore agglomeration drum. Agglomeration drums, also known as agglomerators, are frequently used in processing gold ore at heap leaching operations to improve heap permeability. In this specific instance, FEECO was commissioned to replace a …
This week’s resource highlights rotary drum girth gears. The gear on a rotary drum in a gear and pinion drive assembly setup is an integral component, providing both structural support and rotation. As such, worn gears should be replaced immediately to prevent damage from affecting …
While the heap leaching process has proven to be efficient and cost-effective, efficiency and ore recovery can be further improved through the addition of an agglomeration drum. The following covers an introduction to heap leaching, and how agglomeration greatly improves this essential beneficiation process. A …
As gold continues to be one of the most widely used precious metals, more and more companies are expanding their reach in the gold mining and processing industry. And as with any finite resource in a world of growing demand, reclaiming as much of this …
As the world leader in tumble growth agglomeration, FEECO provides a variety of services and equipment for iron ore pelletizer plants. As the needs of the steel industry change, one production component looks to be increasingly important in meeting the needs of the modern steel …
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: …
