In many processing facilities, the grinding or milling of products is a key element in the process. However,

transportation and conveying are often an afterthought to the design and implemen-tation of the production process. Many times, conveying is added or altered due to increased production capacity, or changes in the production process. Whatever the reason, often the planning of conveyor selection and design doesn’t receive the consideration it deserves, thereby making it a ripe target for many of the problems that a processing facility with a focus on milling can face.

In January 2013, society saw a focus on controlling the risk of explosions within ham-mer mills, with much of the risk associated with these dangerous dust explosions being placed directly on the shoulders of the proc-ess that creates the dust in the first place: bucket elevators and pneumatic conveying systems.

A balancing gameThese systems produce dust as a result of

their daily operation, thus, when using bucket elevators or pneumatic systems, decreasing the risk of dust explosions now requires additional technology and sensors, as well as safety personnel and dedicated cleanup

staff. These advances in technology and the increase in regulations, codes and standards have increased the safety in plants and have reduced the occurrence of dust explosions; but one big problem still exists: they do not address the underlying issue of dust. These means of conveying inher-ently generate dust, and without first addressing this issue, prevent-ing the risk of dust explosions will always be played as a game of ‘catch-

up’.Dust control plays

a critical part in the conveying puzzle. If a transport system is not specifically designed to prevent the prolifera-tion of explosive dust, the processing facility must play a dangerous balancing game between funding additional tech-nology and adding labor force. Cutting cor-ners on

either, and you will risk dangerous explosions that can damage machinery and, most importantly, your workforce.

a huge problem to the milling industry. Over the years, solutions have been sought in varying conveying systems such as bucket, screw, and drag, dilute and dense-phase pneumatic. While each system has its strengths and weaknesses, none control nor reduce the generation of dust.

The superior solutionTo address the problem of

dust generation, Modern Process Equipment (MPE) of Chicago, IL, USA has developed the Chain-Vey, a tubular drag chain

system that utilizes molded-on, food-grade discs pulled by a 316 stain-

less steel chain through a stainless steel tube. The result? A fully enclosed convey-ing design that contains dust and reduces product degradation through gentle and energy-efficient conveying. As a point of reference, the Chain-Vey acts similarly to a bucket elevator, gently carrying segments of product from one location to another. More specifically, the Chain-Vey offers a multitude of additional advantages including: - Completely enclosed design - Flexible design configurations - Long conveying distance capability - Multiple inlets and discharge points - Few moving parts and low

maintenance - Energy efficiency

Typical Chain-Vey configurations

Case 1 (Figure 1)Typical configurations can range from

single inlet or single outlet, to a system with 10 inlets and 10 outlets with multiple twists and turns along the way. No matter the length or complexity of the design, gentle product handling is maintained throughout the conveying process.

Case 2 (Figure 2)In both cases above, (Figures 1 and 2),

the product moves through the Chain-Vey via stainless steel chain and molded-on discs. This chain is extremely durable and will not stretch, fray nor deteriorate.

Turns or corners in the system are accommodated through the use of ‘sweep elbows’ that can range from 10-90 degrees and are designed to minimise friction. When necessary, the design utilizes ‘live corners’ with rotating wheels that eliminate resist-ance, thereby enabling long runs and multiple turn situations.

Typical power requirements for the Chain-Vey range from 1-5 HP and, when compared to alternative conveying systems, such as dilute or dense-phase pneumatic systems, the energy savings can be as much as 90 percent. Assume that the requirement exists for a 100-foot conveyor length at a run rate of 12 hours a day and 250 days

a year. A Chain-Vey will achieve electrical energy savings between $5,000 USD and $10,000 USD per year.

In summary, MPE's development of the Chain-Vey conveyor technology meets the increasingly challenging demands of bulk product transport and is a flexible and efficient alternative to traditional conveying methods.

About MPEModern Process Equipment Corporation

(MPE) is a leading manufacturer of parti-cle reduction equipment. MPE Granulizers achieve a very uniform particle grind distribu-tion with minimal ‘fines’ for various products ranging from dry foods to chemicals and even abrasive minerals. MPE specialises in dry grinding applications where particle uni-formity and grind consistency are desired. MPE also manufactures the Chain-Vey, a tubular drag conveyor that is specifically designed for food, chemical and other bulk powder products. The MPE Chain-Vey can transport products up to 200 feet with mini-mal product degradation. Sanitary and CIP Chain-Vey designs are also offered.
