Ensuring Gypsum Quality

Elements of the ACO DMMS moisture measurement system installed at gypsum production process at E.On's MPP3 Power Plant.
Moisture Measurement
E.ON operate a modern coal- and bio-mass-fired power plant in the Maasvlakte port area in Rotterdam. The necessary desulphurisation is steadily controlled to produce a salable gypsum product. Its product quality is monitored via moisture measurement. Moisture measurement is also advisable to avoid caking in the whole process and to guarantee the best flow characteristics in all following transport systems.

“Clean” Recycling with Atomized Dust Suppression

RAI has successfully employed an atomized mist system to suppress dust in and around its Chula Vista plant.
Dust Control
Reducing the need to landfill huge amounts of reusable debris from road repair includes the processing of these materials during which a great amount of dust is produced. A California company solved its dust problems with an special water mist generator. At first, the company tried to reduce the amount of dust with a sprinkler system. But that just saturated the material and creating a lot of mud, whereas the dust still remained an issue.

Europe’s longest Belt Conveyor for French Cement Factory

Overland Belt Conveyor
Reducing the number of transfer points in long distance conveying results in lower energy requirements as well as in improved product quality due to lower particle attrition. Due to their patented technology a French supplier was able to install Europe’s longest belt conveyor with both flights running side by side, creating a very low construction height. The 6.2 km overland belt conveyor system went into operation at a cement factory in Montalieu, France.

Material Handling of Highest Complexity

Raw Materials Handling
For the expansion of Bhushan Steel’s steel plant at Meramandali, India, Larsen and Toubro carried out the design, engineering, supply, erection, testing and commissioning of the raw material handling system that included 43 kilometres of belt conveyors, a wagon and truck unloading system, eight stacker/reclaimers and three bucket wheel reclaimers.

How to Convey Hot Stuff

Apron Conveyor
Steel apron conveyors are heavy duty conveyors especially for high temperature bulk materials. In the following some design specifications for a long lasting, failure free operation of such systems are presented by means of a newly developed solution.

Down the Rathole

Three air cannons keep the material flowing in a pyramid hopper construction .
Discharge Aids
A cement and concrete manufacturer faced a problem with their storage bins for the raw material, which accumulated in the hopper forming a rathole seriously affecting production. To keep the whole of the material flowing they installed an air cannon system with some interesting specifications.

The CEMA Horsepower Equation

Improved understanding of rubber lies at the root of one of the most important advances in conveyor design. Recognizing this improvement, the latest edition of CEMA offers three different horsepower prediction methods.
Belt Conveyor Design
The 7th edition of Belt Conveyors for Bulk Materials (known as “The Belt Book”) includes a new con­veyor power prediction methodology using “Large Sample Indentation Test” (LSIT) data. This article provides background and insight into how LSIT data is used to design conveyors, and describes the relation between this and the older conveyor power prediction methods. It also illustrates the use of LSIT data by using it to predict indentation losses in a recently commissioned conveyor system.

Vibrators for Hire

A fleet of Martin vibratory drives was rented for a West Texas drilling site, where they operate 24/7.
Screening & Separation
A global leader in engineered vibration for bulk material handling has introduced a new rental program for its line of industrial vibrators, designed for vibratory screens such as shale shakers and other solids separation equipment thus ensuring that customers are protected from surprise repair costs and the associated downtime.
