Capable of causing costly damage to equipment, as well as process inefficiencies and unnecessary downtime, corrosion is a common problem faced when working with rotary dryers. This is particularly true of dryers that were not designed with corrosion in mind. Fortunately, there are several ways …
FEECO recommends keeping a number of bucket elevator parts on hand to facilitate a quick change out in the event of a failure. What follows is a summary of these parts, as well as helpful tips in minimizing downtime, and the information original equipment manufacturers …
While demand for frac sand is nowhere near where it was during the boom seen over a decade ago, the industry is seeing somewhat of a resurgence, putting rotary dryer services in high demand. In the 2010s, producers were looking to get their new plants …
Whether working with a dryer, granulator, kiln, or otherwise, an annual rotary drum inspection is the best way to uphold process efficiency, prolong equipment life, and avoid costly downtime and maintenance. These inspections allow plant managers to catch potential problems early and prevent them from …
Maximizing the reliability and service life of a rotary dryer is the focus of many plant managers. One of the most important, but most overlooked aspects of rotary drum maintenance is ensuring proper alignment, or the positioning of the drum on its bases. Why Rotary …
The disc pelletizer, also known as a pan granulator, is a preferred approach to agitation agglomeration (wet granulation) for soil amendment producers, mineral processors, and chemical manufacturers, favored for its high on-size yield, ability to fine-tune product, and the premium round granules it produces. And …
Rotary drum tires and trunnion wheels can become worn over time, and result in the following changes: Chattering or vibrational noises Pitting Spalling Rolled over edges Timing marks Ridges Taper wear Washboarding The characteristics mentioned above can cause the weight of …
This week’s photo highlights a pneumatic hammer knocker. Hammer knockers are one of many knocking system options FEECO provides to help combat material build-up inside of a rotary drum. Pneumatic hammers are mounted above a strike plate on the drum. An operator controls the hammer …
This week’s photo shows laser alignment in progress. A FEECO Customer Service Engineer is performing the laser alignment on a rotary drum. A state-of-the-art laser tracking system uses a laser beam to measure 3D coordinates (angles and distances) along the rotary drum, which is then recorded and analyzed …
This week’s photo shows pitting on a trunnion wheel. Pitting, or deep indentations, can develop from improper lubrication and/or normal wear and tear associated with trunnion wheel operation. Pits are never ideal; they will expand and cause the weight of the drum to be unevenly …
