Tiger-Tuff : Max-Duty Elevator Bucket Hits 2 Million Sold

Addison, TX -- Maxi-Lift Inc. is pleased to announce that Tiger-Tuff, the industry’s only Maximum Duty elevator bucket has achieved a major milestone. Two million Tiger-Tuff buckets sold. This number is a tremendous achievement considering this product was introduced just 10 years ago.

Tiger-Tuff buckets have been sold into every grain handling category, from ethanol production and oilseed processing, to river, rail and ship loading facilities. It is also successfully used in industrial applications such as cement and sand handling. The bucket is currently in use on six continents in dozens of countries.

“When we introduced the Tiger-Tuff ten years ago, we were told it would never catch on. Two million buckets and thousands of satisfied customers have proven we were right all along. When you build a better product, the market will respond, and they have.” Said Bo Fisher, Director of agricultural products for Maxi-Lift.

Designed to give long life, the Tiger-Tuff is available in polyethylene, nylon and urethane in 14 sizes ranging from 12x7 up to 20x10.

Established in 1973, Maxi-Lift has become the premiere supplier of elevator buckets to customers worldwide. Our product line includes plastic and metal elevator buckets, elevator bolts, elevator belt splices, screw conveyor hanger bearings, drag conveyor flights and UHMW sheeting products.

Maxi-Lift's elevator buckets are used around the world to elevate everything from agricultural products like corn, wheat, soybeans and fertilizer to industrial products like concrete, clay, sand, and cement.

BMH : Houston Cement Company Orders New Ship Unloader

BJUV, Sweden -- BMH Marine, the world leading supplier of continuous screw-type ship unloaders, secured a contract for the delivery of a new high capacity Siwertell ship unloader for cement. The new unloader has inherited its structural design from the Siwertell heavy duty unloaders and its conveying system from the former cement unloaders but with screw conveyors of a larger size.  The well proven unloader of model Siwertell ST 640-D will now for the first time be used for high capacity cement unloading at a marine import terminal. The customer is The Houston Cement Company, L.P. located in Houston Texas, USA.

The efficiency of the new unloader is further improved in comparison with the 800 t/h unit, and additional features originally developed for the 800 t/h unit are also available for the new unloader series ST 640-D. As a part of the new contract, BMH Marine guarantees an hourly rated unloading capacity of 1500 t/h and a through-the-ship capacity of 1050 t/h for the rail-mounted unloader.

One of the reasons to invest in high unloading capacity combined with high efficiency is the high freight rates. With the high capacity and efficiency of the new Siwertell unloader the customer almost reduces the ship costs in port by 50% compared with an 800 t/h unloading system. As a result the reduced berth occupancy will allow other activities on the dock.

The new Siwertell cement unloader will be delivered in February 2006 and is scheduled to be in commercial operation at the mid of the year.

BMH Marine in the early 1980s established an industry standard for 800 t/h cement unloaders with its continuous, screw-type Siwertell units. Now the company sets up a new milestone in the evolution of high capacity unloaders with the introduction of a cement unloader with an unloading capacity of up to 1650 t/h. BMH Marine’s vast experience in high capacity unloading of various dry bulk materials was one of the main reasons to place this contract with BMH Marine. More than 235 Siwertell screw-type unloaders have been supplied since 1974 for a wide range of dry bulk materials, among them 35 with capacities of 1000-2000 t/h, and in total 130 for cement.

Malvern : Introduces New Particle Analyzer at Coatings Show

Malvern, UK -- At this year’s European Coatings Show (26-28 April 2005; Nurnberg, Germany), Malvern Instruments will introduce a new at-line particle size analyzer package for dry powder processes, Stand No: 4-202.

The new Malvern At-Line Insitec OPS is designed to enable powder processors to make automated measurements close to the process line. The at-line approach - using a rugged and proven industrial particle size analyzer capable of measuring large sample volumes at relatively high concentration and throughput - offers users taking manual measurements the benefits of robust on-line technology, secure in the knowledge it can be upgraded to a full on-line system at a later date.

The new package is based on Malvern’s award-winning Insitec Voyager, a self-contained mobile Plug and Play device for on-line particle size analysis that can be moved around a plant for use on different process lines or to sample at various points in the same line. The new at-line system uses the same proven Insitec technology, but does not require dedicated sample ports. Instead there is a pneumatic dry dispersion unit for sample presentation, which can be operated manually or automatically and can be interfaced with existing sampling systems at the user’s site.

Two at-line packages are available, one that is ideal for automated laboratory system integrators and a second which also includes Malvern Link software to carry out all the analyzer control functions.

Livingston, NJ -- The powerful Delumper® HD Crusher offers truly robust construction for a variety of tough size reduction applications. This unit is built to handle heavy loading of salt, coal and other solids intensive applications that can choke or break lesser units. It can handle heavy head of solids loading as from a backhoe or railroad offload feed system.

The Delumper is designed and built for long dependability. It is constructed of heavy welded structural steel and provided with wide flanges for easy hopper connections. Features include one-piece heavy duty cutting rotors with extended crushing teeth force multiplying pick edges that rotate through a heavily constructed bar cage. This provides positive reduction of tough solids without hang-up or heat rise, stagnation or degradation.

All cutting surfaces are hard-faced for long life in abrasive service. Other features include packing shaft seals, splined shafting and three independent hydraulic drives with auto-reversing for jam alleviation.

This unit is a Delumper Model DC4240HD with a 42" x 40" infeed opening. The HD is available in single, double and triple shaft versions to handle a wide variety of capacities.

Mr. Ermini wants information about drag conveyors:

I need to change my material reject process from a vacuum air system to a drag conveyor. The material is wood fiber with resin, bulk density is 10 lb/cft and tonnage of 22 ton/hr. The main problem is the conveyor will need to pick up the material in the horizontal then make a 90 deg, turn upward, proceed about 35 ft up the go back to horizontal.

I think that a SC Enduro-flo Compartmentalized conveyor will work. Is there any other Manufactures of these kind of conveyors? How well does this type of conveyor work? Any help would be beneficial.

Mr. Miller needs help with vacuum conveying of PVC:

I work for a copper wire insulator where we vacuum convey PVC pellets from silos to our extruders. The overall design of the system troubles me and I would like some comments from those more familiar with this area.

We have multiple vacuum pumps equipped with 30-50 HP AC motors running across the line serving about four extruders each. The system is set up to draw 15 inHG vacuum, above that spring loaded valves open to add air to the system. When a particular extruder is in need of compound, the appropriate vacuum pump is started and valving is closed to deliver a load of compound based on a preset timer. Once the extruder is satisfied (could require multiple timed loads) the vacuum pump is turned off and all of the vacuum is relieved to atmosphere.

To me this system design seems terribly inefficient. Why would this not be treated like a compressed air system where there are large tanks, pressure transducers, VFD's or other energy saving approaches. Why build up vacuum and then just let it go to atmosphere? Is this a typical setup? I keep envisioning a large vacuum tank with redundant vacuum pumps running in an alternating master/ slave configuration possibly with a single VFD and the appropriate valving to vent as little vacuum as is practical.
