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 …
This week’s highlighted resource is a Slideshare presentation on the use of a pin mixer for processing gypsum. Gypsum is widely used as a soil amendment, but it is first processed into granules for improved handling and application characteristics. Using a Pin Mixer to Process …
This week’s highlighted photo shows material being processed in a paddle mixer. The photo was taken at FEECO’s Innovation Center, located in Green Bay, Wisconsin (USA). Paddle mixers, also commonly referred to as pugmill mixers, work by utilizing two paddle shafts within a horizontal trough. …
While some materials may be self-binding, in most cases, the right binder is vital to agglomeration success. In general, binders: Improve bonding forces and pellet durability. Help to achieve the appropriate wet strength and dry crush strength. Are inexpensive and readily available. …
Gypsum, or calcium sulfate dihydrate, is a common element found worldwide. In fact, over 90 countries mine more than 110 million tons per year. Gypsum’s global prevalence is fortunate considering its versatility. It is a key ingredient in cement, plaster, and even building materials. Gypsum …
Today’s photo highlights a set of replacement paddles for a pugmill mixer. Abrasive or corrosive materials may cause premature wear on paddles. Regular wear, over an extended period of time, may also serve as a reason to seek new paddles. No matter the reason, paddles …
Our photo this week comes from the FEECO fabrication facility, where a large disc pelletizer is under production. Disc pelletizers, commonly referred to as pan pelletizers or pan granulators, are used to turn material fines into easy to handle pellets, and are often chosen for …
The pugmill mixer is an incredibly diverse machine, lending itself to blending, conditioning, mixing, and agglomeration processes throughout a host of industries. While a well-designed and properly manufactured pugmill mixer is generally reliable, it is not immune to issue; changes in process conditions, the presence …
