More than 30 million tonnes of potash are produced worldwide each year, making it an important mineral for a number of product manufacturers, as well as an integral component in fruitful crop production. However, potash’s widespread use does not mean it is always easy to …
Limestone and gypsum are regularly pelletized for use as soil amendments and other products. Unbeknownst to many, however, limestone and gypsum respond so readily to agglomeration, that they are often employed as an additive in the pelletizing (agitation agglomeration) process when working with hard-to-agglomerate materials. …
Micro-pelletizing is the process of agglomerating material fines into small pellets, or micro-pellets, from 20-60 mesh. It is can be carried out in either pin mixer, or a pin mixer/pan pelletizer setup. Pin mixers alone are ideal when only small pellets or material conditioning is …
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 …
When processing any material, it is important to recognize key characteristics that will affect manufacturing operations and the product generated. Even well-known minerals such as gypsum require testing on a case by case basis to ensure quality results. The following list outlines key material characteristics …
From drywall to soil amendments, and even tofu, gypsum products surround the average person every day. In fact, the United States alone consumes more than 30 million tons of gypsum annually. Gypsum has many unique characteristics that contribute to its popularity, and gypsum processing works …
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 …
Bulk solids processing is perhaps the most fundamental aspect of modern industry. Each and every day, bulk solids are handled and processed by the ton to convert mined ores into refined metals, produce market-ready products from raw materials, and so much more – all to …
