Limestone and gypsum are regularly pelletized for use as soil amendments and other products. Unbeknownst to many, however, these two materials respond so readily to agglomeration, that they are often tested 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 Continue reading →
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 Continue reading →
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 Continue reading →
Continuous mixers play a vital role in a wide array of industrial process settings, de-dusting materials, promoting product uniformity, streamlining downstream processes, and so much more. And while the capabilities of a continuous mixer are many, so too are the number of manufacturers offering these Continue reading →
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 Continue reading →
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 Continue reading →
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. Continue reading →
With producers and buyers becoming more discerning, the need to produce high-quality granular fertilizer products has never been more important; producing a product exactly to the desired specification has become a necessity in today’s ultra-competitive market, particularly when it comes to specialty fertilizer and soil Continue reading →
Iron ore is a critical raw material in modern society; it is the basis of the steel industry, which provides us with everything from infrastructure to appliances. Courtesy of iron ore, steel is all around us. The production of steel from iron ore has increasingly Continue reading →
