- The operating stages in mineral processing have remained the same for thousands of years. Crushing and screening is the first controlled size-reduction stage in the process. Reducing the size of minerals, ores, and rocks is almost always accomplished in stages. A classical three-stage crushing approach consists of three steps.Full story
- Dry separation equipment first appeared over a century ago when Edwin Steele and Henry Sutton, principals at Sutton, Steele & Steele, Dallas, Texas, invented the fluidized-bed separator, then called the specific-gravity separator. The firm held dozens of patents on dry concentrating methods that used static electricity, air, vibration and combinations of the three to accomplish their purpose.Full story
- While most engineers in the dry process industry know what a gravity separator does, precisely describing how it works can be difficult. The statement “a separator classifies dry, free-flowing, granular mixtures by weight or bulk density or specific gravity” is accurate. But a more precise definition would add the qualification “if all of the particles in the mixture are the same size and shape.” With equal accuracy the statement could be turned upside down “if all of the particles are the same shape and specific gravity, the separator will classify them according to size.”Full story
When considering capital equipment purchases, end-users often fall into the trap of focusing narrowly on the purchase price. This a particularly hazardous misstep when it comes to investing in conveyors for industrial process applications. Total cost of ownership is a better measure than purchase price when considering the ultimate return on investment for conveyor systems.
The ongoing costs after you’ve written the check for that piece of capital equipment are just as important as the purchase price.

Few companies in the U.S., or the world for that matter, are as easily identifiable by their package as the Campbell Soup Company. A long time proponent of advertising, the Camden, New Jersey-based food processor is as recognizable for its “Mmm, Mmm Good” slogan and iconic soup can as it is for the contents inside. Andy Warhol’s interpretation of the can during the pop art move ment of the 1960s only pushed Campbell’s brand recognition to greater heights.

As overall equipment effectiveness (OEE) insinuates itself in every sales opportunity, OEMs know that customers have a certain number in mind that represents their required OEE.
The problem for OEMs is determining how their customers define that number. One company might perceive another company’s accepted efficiency differently, as there are many ways to calculate—downtime related to changeovers, product in vs. product out, etc. There is also a variety of calculators out there for determining OEE.

Adding production capacity to an already crowded processing line can feel like asking for your cake and eating it too. Most often, increasing production means building a plant addition. But one potash producer was able to ncrease production by finding a more efficient screener.
- Using fluidization, any dry mixture can be separated by density, shape, or size. Fluidized bed separators and the Stoner are a means to separate any dry, granular mixture that you might have. This paper aims to provide an understanding of each device and demonstrates why you should be using them.Full story
- This paper describes the application of vibrating conveyors to the handling of ash from mass-burn incinerators. The characteristics of two different kinds of conveyor, the natural frequency vibrating conveyor and the differential velocity, or “horizontal differential” conveyor, are compared. Factors to consider in selecting and specifying a conveyor design are discussed, in relation to performance, maintenance and abrasive wear.Full story
- Horizontal motion conveyors, or differential motion conveyors, have been used in the mining industry for a long time, but only after a breakthrough by Triple/S Dynamics did these conveyors really become as valuable and efficient as they are today. Triple/S offered a slow-advance/quick-return advantage as well as versatility and extensive application in their conveyors. Today horizontal motion conveyors have made a presence in a wide array of industries for many uses.Full story
- Sometimes you have materials that are not easily transported, but luckily horizontal-motion conveyors are made to handle these difficult materials. Horizontal-motion conveyors move in a way that can handle very fragile elements without breaking them, and also can operate at variable speeds and can operate in reverse. This article points out some advantages of these conveyors and some factors to consider when deciding to buy a conveyor.Full story
- This paper describes the applications of and specifications for trommels as used in various waste processing and resource recovery operations. It provides system design engineers with general guidelines and rules-of-thumb useful in defining performance requirements, as well as creating design and construction specifications for trommels being used in areas such as raw MSW p ocessing, classifying C&D debris, sorting for MRFs, screening mass-bum incinerator ash, and compost processing. Additionally, the paper compares the trommel to alternative screens, such as the vibrating and disk screens.Full story
- Conveyors have become the lifeline of food production, and many features such as robustness, cleaning capabilities, and automation have become important aspects needed for food producers. Two features, accumulation and buffering, have become important in order to provide relief in the face of machine failure and maintain efficiency. Triple/S Dynamics, among other firms, has gone to lengths to provide these features and others to further improve modern material handling.Full story
- Food safety is a real cause for concern and should be taken seriously. As the food production industry moves forward, manufactures of food production equipment must focus on safe design and efficiency. The current and future goals of material handling companies is to make products with quick turnaround and with compliance to food safety initiatives, such as the Food Safety Modernization Act. Read to discover the current, as well as future, technology and conditions of the food production industry.Full story
- Horizontal-motion conveyors can effectively move many different materials for a multitude of applications. Horizontal-motion conveyors offer simplicity and many advantages over other conveyors. Answering some common questions, this article aims to provide a better understanding of these conveyors and how to use them.Full story
- Accumulating equipment can eliminate production slowdowns and improve process efficiency by temporarily storing dry bulk material during process interruptions and holding it for later release, After describing various types of accumulating equipment, this article explains how to choose equipment that can handle your material, fit your available space, and meet your other requirements.Full story
- Hopkinsville Elevator has been around since 1968, and since has expanded to multiple locations and a storage capacity of 15 million bushels. When they decided to expand the cleaning capacity of their cooperatives, they selected none other than the Texas Shaker. The Texas Shaker didn’t meet their expectations, it exceeded them.Full story

- After being consulted by a food producer frustrated with their existing parts, Triple/S Dynamics was faced with a task to make come custom conveyor gates. Triple/S designed the gates from scratch and sent the customer their new prototype. When Triple/S received some very positive feedback, they started carrying the prototype as a standard part for the Slipstick conveyor.Full story
- Angular-pitch vibrating conveyors and horizontal differential-motion conveyors are two common means to convey dry, granular solids. Angular-pitch vibrating conveyors are made up of a trough and a mechanism to oscillate it and come in a brute-force type and a natural-frequency type. Horizontal-differential motion conveyors move objects by way of differential friction while offering smooth and safe handling of the objects. Provided are some quick facts of both conveyors and some considerations to look at when selecting either conveyor.Full story
