New Sponsor : Minox/Elcan

Jacksonville Beach, FL -- We are pleased to announce that Minox/Elcan has become a sponsor of Powder and Bulk Dot Com.

Since 1985, Minox/Elcan has worked with customers to find and implement advanced screening solutions. Prior to 1997, the primary technology utilized to improve screening performance over traditional vibratory screening machines was Minox Tumbler Screeners. The gentle 3 dimensional motion settings and unique anti-blinding devices. Through superior customer service as well as very profitable returns on our improved screening performance, we developed a brand recognition as Minox/Elcan.

Minox/Elcan now works with Kroosh Technologies developing a different type of screening machine. The Kroosh adapters provide high amplitude/ high energy to the un-tensioned screen surface. The Kroosh machines can be used in wet or dry separations and are available in round or rectangular configurations.

"The solution to fine and difficult screening problems"

Minox/Elcan also offers Toll Processing services. Customer demands for developing new products, outsource low volume products, improve experience/techniques, or hassle free outsourcing of difficult to screen materials initiated the expansion that doubles our processing space. We work with all different size quantities and separation requirements.

FLSmidth acquires Conveyor Engineering

Copenhagen, Denmark -- FLSmidth and the shareholders of Conveyor Engineering, Inc. have entered into a stock purchase agreement effective 1 March 2009.

Conveyor Engineering specializes in the design and supply of major bulk material handling systems for cement, mining and heavy industrial facilities worldwide. The purchase price will depend on the earnings performance in the coming years.

The acquisition of Conveyor Engineering will enable FLSmidth to continue to strengthen its global growth strategy within the minerals industry while at the same time supporting FLSmidth's cement business.

"This acquisition demonstrates that even in temporary market downturns there are investment opportunities that are so good strategically that they improve shareholder value considerably. Conveyor Engineering's capabilities and technical resources will strengthen FLSmidth's position as world leader in distinctive and specialized material handling solutions," Group CEO Jørgen Huno Rasmussen comments.

Established in the early 1950s, Conveyor Engineering is headquartered in Boise, Idaho, USA with offices in Santiago, Chile and employs 48 people. In 2008, Conveyor Engineering delivered a turnover of approximately USD 50m.

Conveyor Engineering's heritage, track record and reputation for providing high capacity large delivery systems will augment FLSmidth's portfolio of equipment, systems and technology. In addition to high performance, high tonnage cross country systems, Conveyor Engineering designs and supplies in-plant conveyors, belt feeders and heap leach stacking systems for the cement and minerals industries.

Free : TurboSim Software for Belt Conveyors

Crailsheim, Germany -- Conveyor systems in mining applications are reaching higher and higher outputs. On the one hand, this makes increasing demands on materials and functionality, on the other hand, plant engineers request detailed information on the anticipated start-up behavior already during the project stage.

Voith TurboSim is a simulation tool for the evaluation of drivelines with hydrodynamic couplings. This applies especially to belt conveyors. Voith TurboSim simulates the actual operating torque and consequently serves as a basis for dynamic plant calculations. The software program allows the computer-supported design of fluid couplings, provides higher planning safety, reduces operating risks, and helps with the evaluation of output reserves.

In order to minimize risks that might occur during the design and commissioning phase, computer programs for the evaluation of critical operating conditions of belt conveyor systems are becoming increasingly popular. If belt tensioning forces, the lift-off of the belt, belt slip, or voltage drops can be evaluated already during the project stage, the risk of a later operating failure is much reduced.

The increasing output rates of conveyor systems also affect the drive system; after all, the start-up procedure plays an important role for the load on the belt. Here, the torque characteristics of the fluid coupling are a key factor. They decide the start-up behavior of the driven machine and hence ensure that belt conveyors start smoothly.

The Entire Operating Procedure Can Be Simulated

The introduction of torque to the belt via the hydrodynamic coupling can be optimized by demand-oriented curve characteristics. But the characteristic curves of hydrodynamic couplings cannot be calculated mathematically. The calculation program TurboSim therefore has a comprehensive database of the characteristic curves of constant-fill couplings collected during empiric studies in test series.

These curves focus, for example, on start-up times, the possible number of subsequent start-ups and the behavior of the motors. As these characteristic curves are processed directly, plant engineers receive near-realistic representations. Once these limitations have been taken into account, the start-up procedure can be simulated. The simulation covers the entire operating process.

The program consists essentially of two elements. The first element is used for the automatic pre-selection of a coupling type on the basis of fixed criteria. For this purpose, the plant operator provides the central performance data of the system (speed, load collective, motor output, and mass inertia). With this data, TurboSim can compile an overview of possible coupling types that would be suitable for this application. Customer requirements, such as torque limitation, ambient conditions, and frequency of start-ups are then added, in order to narrow down the selection even further.

With the second element, start-up procedures of Voith fluid couplings for all kinds of plants and load collectives, for example single or multimotor drives, as well as all operating conditions (start-up, nominal operation, shut-down, and special applications such as creep speed for inspection runs) can be simulated. The results from these simulations can provide valuable insight, especially when evaluating output reserves.

Assessable Program Results Lead to Cost Optimization

These early-stage evaluations offer project engineers more scope for deciding which drive is the most suited. They increase planning safety, from projecting to commissioning and operation. They also show possible effects on the functionality of the entire system. Here, the program resorts to the database containing product details from case studies and test series. The processing of these data sets during the project stage allows secure statements regarding the anticipated operating conditions of the fluid coupling in the driveline.

With the help of TurboSim, plant engineers receive realistic characteristic curves of the fluid coupling for plant calculations – namely torque values that might occur at any time in dependence on the speed of the belt conveyor. On the basis of assessable program results, the introduction of power into the belt, as well as other plant components, can be optimized, resulting in possible cost optimizations.

New Dust Caps prevent material accumulation

Neponset, IL -- Martin Engineering has introduced Martin® Dust Caps, a simple yet effective way to prevent the problems of material accumulation and corrosion at the base of conveyor structures.

The buildup of fugitive material on the floor or ground around belt conveyor supports creates a mess and potentially a fire hazard. These buildups also capture moisture, leading to the corrosion and weakening of the conveyor structure. Installed on the “legs” of the conveyor, Martin Dust Caps prevent these material accumulations.

Made from accumulation-resistant molded polyurethane, Martin Dust Caps are pyramids that cause the material to fall away from the conveyor foot, making it easier to collect dust clean by washing down or sweeping around the conveyor.

New Martin Dust Caps are safety orange in color, for improved visibility. They are available in 3- and 4-inch sizes (and metric sizes) to fit the structural steel angles used in conveyor construction and can be installed on new or existing conveyor systems.

Covered by pending patents, Martin Dust Caps are one of the first products from Martin Engineering’s New Architecture for Modern Conveying.

Mr. Nichols needs to meter wet PTFE from blender:

I am looking for a material handling solution for moving wet PTFE (~10-20% solvent) from a PK Blender to a system that will meter the material into a cell. The PTFE cannot be piled to high because it will pack.

If this is something that you may be able to help with, I can provide more details.  (to post reply, click here)
