A Northern California, USA, processor in operation since the mid-1920s, processes barium ore into various barium compounds. The mineral is obtained primarily from holdings in Nevada. The company set out to find a more efficient screening operation for barite ore, barium oxide and barium carbonate.
At that time conventional 3 ft. x 5 ft. rectangular screens were in operation. Two different models of the SWECO Vibrating Screen Separator are now in operation at the California Plant.
Using a 48” diameter SWECO Separator the company now screens barite ore weighing approximately 180 pounds per cubic foot at the rate of 10 tons per hour output at minus 10 mesh fraction. The separation is performed on a 6 mesh stainless steel wire cloth (opening of .1318 inches, 3360 microns) and a 10 mesh stainless steel cloth (opening of .0742 inches, 2000 microns). The desired product is taken at minus 10 mesh.
Barium oxide grinding material is fed through a SWECO single-deck unit at the rate of 2 tons per hour. The separation is made on a 40 mesh stainless steel cloth (opening of .0185 inches, 400 microns). The plus 40 mesh fraction is desired.
A single deck unit with dust cover is used to screen lamp black for consumption within the California Plant. A single deck SWECO Unit with 20 mesh stainless steel cloth (opening of .0340 inches, 841 microns) is used and the minus 20 mesh is the desired product used in a closed circuit with mill.
The SWECO Vibrating Screens Separator are gyratory in principle in that the material is tumbled around, across and vertically on a horizontal screen cloth. More than one cloth can be “decked” one above the other. The cloth is mounted especially on tension rings which in turn can be rotated 45 to 90 degrees at intervals. The company thus extends screen cloth life considerably.

Article snippit from April 2016 VALVE Magazine. By Kate Kunkel, Senior Editor. Greg Johnson president of United Valve also contributed.
The U.S. food industry is forecast to grow at a steady rate of 2.9 percent compound annual growth rate through the year 2022, according to a recent report from PMMI, the Association for Packaging and Processing Technologies. The fastest growing two segments are meat and snack foods.
The 2016 Food Packaging Trends and Advances also reported that the U.S. trails the global market-global growth is forecast at almost twice the U.S. rate. The report says overall growth of the food industry, including food packaging, is driven by emerging markets such as Argentina, Brazil, China and India. It also says that the most innovative food industry segments (snack food, meat, fruits and vegetables, and pet food) are using tools such as films that keep products fresher longer, recycled or biodegradable materials for packaging and single-service portioning.
(Lohre & Associates specializes in marketing food processing equipment, this new product release for our client Roto-Disc is appropriate for this topic so we added it to this post. Currently we are researching economic predictions for future posts on the food, chemical, primary metals and warehousing industries. They will be posted during the Powder Bulk Solids Conference in Chicago next week.)
Roto-Disc, Inc., now offers a full-range of process transitions that make the task of mating equipment and piping with non-matching dimensions easier and quicker. Now the dry process industry has a selection of piping, flange and duct transitions available from stock, eliminating the time, expense and hassle of specifying, designing and fabricating transitions from scratch.
Among the many options available are round-to-square pipe transitions, square and conical reducers, flexible stub adaptors and sanitary pipe/tube extenders with clamp ferrules. Transitions are available with flanges on one or both ends as are flangeless/weld stub transitions. The entire line can easily be adapted to meet custom take-out space requirements and flanges can be drilled to suit. Custom shapes such as offset/oblique, rectangular and double-cone types can also be provided upon request.

From Chemical Engineering Magazine, Webinar June 14, 2 p.m. EDT, $95
This webinar examines the current status of the U.S. chemical industry as well as its outlook over the next several years. We will start with examination of the economic environment, with further emphasis on housing, light vehicles and other important end-use markets. We will then focus on: 1) basic chemicals and synthetic materials; and 2) specialty chemicals.
Our premise is that fortunes of the former segment represent a supply driven gain in output, the result of the shale gas revolution and the renewed competitiveness of the U.S. industry. Changing energy dynamics are playing a role and we will analyze the effects of low oil prices are having on competitiveness, uncertainty and the wave of announced investments. Our premise is that fortunes of the latter segment represent a demand driven gain in output, the result of the manufacturing renaissance currently underway.
We will analyze the effects of the current soft patch in manufacturing and how it affects the various specialty chemical segments. Of particular interest to those in process engineering and chemical company capital programs we will assess the unprecedented wave of capital spending (and capacity expansion) by segment, by asset, and by geography.

I was very touched by this tribute of Vac-Con’s about of the loss of their dealer, Dave Berube.
Those of us that grind out as relevant content as we can, day in and day out, need to take a step back and realize that industries are made up of people. People that have families, friends and business associates. I feel that way about my clients and it’s a privilage to have their sincere interest in my family and interests.
My most recent revelation about marketing is that all those digital clicks and links are real people so treat them like real people. Sure the analytics make it all seem like a bunch of robots but you need to filter that out and pay attention to what matters.
I’m lucky to have some great employees and my wife who polishes my copy and keeps me from being silly. I might be over stepping my bounds now but thank you sincerely Vac-Con, your message shows you’re a great company and care deeply for your associates. Thanks for helping keep all of us grounded and reminding us to take pride in our communities and thank them for what they mean to you.
Here are some pointers for preparing a Food Engineering Field Report—also known as an application story, success story or an application brief for our Dry Processing Technology section.
A Dry Processing Technology Field Report describes a problem and its solution. It may involve any product used in the food processing industry; for example, feeders, screening equipment, size reduction equipment, mixing/blending, bulk bag filling & discharging, mechanical conveying, pneumatic conveying, dust control, weighing systems, storage systems, micro and macro ingredient handling systems, thermal processing equipment (ovens, dryers) packaging equipment, metal detection/magnetic separation, process control system hardware and software, and so on. If you’re not sure whether your product, application or service applies, please call and we’ll brainstorm it. See sample Dry Processing Technology Field Reports attached.
Absolute requirements for publication
A submittal must contain the following or it will not be used.
Body copy of 500 to 700 words
At least two end user (food processor) quotes: perhaps one describing the problem and one suggesting that he/she is pleased with the solution, which should be quantifiable. That is, for example, it saved xx amount of time, reduced energy costs by xx percent, or the process improvements increased OEE by xx percent.
If you are unable to get end user (food processor) quotes, we may still have interest in the application story. We use this version online and in our bi-monthly eNewsletter. Think of these stories coming from a well know cereal manufacture or leading snack producer perspective. We require the same information, without the processor quotes or references.
Name of user company and name and title of person being quoted at the user Company
Quotes from supplier companies will not be used, and will be turned into straight text when appropriate.
Photograph of product, service, software at the food processor’s site—not a straight
product shot! Photograph must be print quality; that is high resolution jpg at 300 pixels per inch (ppi). Recommended physical size is at least 5×7 inches. Do not send Web quality. Don’t forget a suggested caption and photo credit. You may send more than one photo. Do not savescreen dumps as jpg files! Use a non-destructive format (tif). Call for instructions!
Real name of a person, phone number and email at the supplier for more information
Please advise as to where this story may have already been published. If it has been used on a
competing publication’s website or in a printed magazine, we won’t be able to use it. If it’s been
published on a supplier’s website, we can use it as long as it’s not more than a year old. Obviously, if exclusive rights to use the story have already been given to someone else, please don’t send it to us. Please make sure of this first. Also, be sure you have cleared the story with the processor.
Please note: These stories are used on a FIFO basis (first in, first out). Publishing dates cannot be guaranteed, but complete submissions, of course, will be published before incomplete submissions.

(Great article in the recent issue of POWDER BULK ENGINEERING by Dwight Rider, SWECO Global Product Manager for round separation. Every good process equipment marketer knows that if you take the time to educate a person new to the industry, they will remember you when they are looking for solutions to their problems.)
There is more to providing a solution for your application than simply purchasing new equipment. Purchasing a piece of equipment is easy: all you need is money and someone to sell it to you. However, the cost of purchasing the wrong equipment can exceed the money you spend on the equipment itself. Before you go and tens of thousands of dollars on capital equipment, there are many factors that need to be considered.
Testimonials alway tell the best story about your process equipment marketing and the editors can’t get enough of them!
In the case of separation equipment, some types of machinery can last decades. Buying the wrong equipment can have long-term consequences in the cost of consumables, lack of production, downtime, and other factors. For example, the amount of money spent on consumables alone could exceed more than half the cost of the unit. Separation equipment is typically integrated into a large system. By choosing the wrong separation equipment, you could be inadvertently creating a bottleneck that affects the productivity of the overall system. Quite often, the low-cost equipment option may be the costliest in the long run.
Round separators are one of the more common types of separation equipment. Aside from the obvious influences of equipment quality and performance, two of the more important attributes when considering an equipment manufacturer are application experience and local support.
Every separation application is different even if you are screening the same product. Application experience cannot be overlooked when determining which manufacturer you choose. If you expect to get optimum performance from your equipment, there are factors that must be considered, such as machine diameter, screen mesh type, number of screen decks, types of self-cleaning devices, proper surface finish, spout heights and sizes, and many more.
Unit selection and sizing for a particular application can be both science and art, and experience is critical to achieving satisfactory results. The manufacturer should come to your facility, review the application in person, and provide services such as on-site testing with a small demo unit if needed. If larger scale testing is required the manufacturer should be able to provide lab testing and detailed test reports to aid in equipment selection.
For applications similar to an existing one, the manufacturer should be expected to review the process on-site to ensure optimum efficiency of the separation process. New applications should be sourced from existing reference data for similar applications that can be used as guidelines. The equipment needs to be customized to be optimized for both performance and integration into the larger system. Finally, engineering drawings, structural loading information, 3D CAD models, and detailed customized operating manuals need to be available to the customer.
Installation, start-up, commissioning, and on-going support are major factors to consider when choosing a manufacturer. If these elements are not available to the customer, complications could arise from the start. It is extremely important to have an expert readily available in case problems arise not only in the beginning stages, but also through the life of the equipment.
The manufacturer’s local support can also provide equipment training for operators and maintenance personnel. Dynamics such as motor lubrication and change-out, screen changing techniques, electrical interface, start up and shutdown procedures, emergency shutdown, and proper separator clearances and just a few items that the users will need to know. Another function provided by local support is recommending spare parts and how to care for those parts. Spare screens are critical to the process, as they will have a big impact on minimizing downtime.
There are plenty of round separator manufacturers from which to choose, and there are a lot of factors to consider when making the choice. Simply buying the equipment based upon a selling price alone may cost you more in the long term. You need to be sure to consider the factors discussed, so you are finding an application solution rather than simply buying equipment. When you need aftermarket parts, technical service, or assistance with the next application, be sure to choose equipment from a practiced manufacturer who has the knowledge, experience, and support you will need to get the job done right.

With responsibilities expanding, resources declining, and margins narrowing, companies today must scrutinize every dollar spent. Bad decisions are often based on bad data. An informed decision, on the other hand, can be defended in the light of the facts. In this article, we examine three misconceptions – misconceptions which too often lead to poor decisions about training.
If I train my people, they will leave.
In today’s companies where people change positions frequently, training is seen as a risky investment. The correct perspective is seeing the risk involved in NOT training your people. Do you really want your people making costly mistakes by the trial-and-error method of on-the-job training? Lack of training does not just affect the untrained person. Those that have been trained and are doing the job correctly often get pulled aside to explain procedures to the untrained. The bottom line is that people are going to be trained one way or another. What is the most efficient way to do this?
I can’t afford the downtime to send my people to training.
Tools need to be sharpened. This means they can’t be “productive” 100% of the time. “Productivity” needs to be seen as a totally different thing from being “busy.” Once a tool is sharpened, it is far more productive. A dull tool can be “busy” 100 % of the time accomplishing nothing of value. The correct perspective then is that you can’t afford the loss of productivity caused by a lack of training.
All training offered out there is basically the same, so just take the cheapest one.
Training is not a one-way dump of information. Training means that a change has taken place in a cognitive domain, an affective domain, or a psychomotor domain. For automation companies, these three domains are intricately linked. For example, it is not enough to just sit through a safety presentation: you need to know the safety regulations (cognitive), you need to be passionate about why these are important (affective), and you need the skill necessary to implement these regulations by specifying, configuring, and integrating systems (psychomotor).
The best way to train in the psychomotor domain is through hands-on training. Students learn skills best by practicing those skills. For many companies who offer training, training is just a presentation of ideas without the necessary opportunity for participants to try anything for themselves. At Balluff, we have made a substantial investment in equipment, an investment in writing courseware properly, and an investment in training those who conduct the training with platform skills, adult learning skills, and teaching skills. These investments make world-class, performance-based training available to our customers.
