Effective Utilization of Alternative Fuels
During the most recent decades the utilization of (otherwise) waste materials and biomass as alternative fuels in the cement industry and power plants showed great growth figures. However, the low heat values of alternative fuels require larger handling and storage systems that are more flexible. This article shows, how these materials can be handled.

Considerations about the Cost of Conveyor Belting – Discussing re-evaluated Belt Safety Factors

Safety Factors for Conveyor Belts
New conveyor belts and belt monitoring technologies reduce conveyor belt capital and operating costs by using lower belt strengths than previously thought possible. Key factors are improvements in splice performance, rubbers and real-time belt condition surveillance systems.

New Barge Mounted E-Crane at Mulzer Crushed Stone

The E-Crane ordered by Mulzer Crushed Stone has has a maximum duty cycle capacity of 16.5 t and a maximum outreach of 26.4 m.
Barge Unloading
In early 2016, Mulzer Crushed Stone ordered an E-Crane which will be mounted on a deck barge. The E-Crane has a maximum duty cycle capacity of 16.5 t (18.2 short tons) and a maximum outreach of 26.4 m (86.5 ft). This is a flexible mobile floating offloading platform that allows barge unloading to a shore mounted hopper, floating hopper or direct to trucks depending on the product and location. The floating rig incorporates the latest design for spud operation, barge haul winches and power distribution.

Pipe Conveying the next Stage

Pipe Conveyor Systems
A new conveyor design is set to help reduce conventional heavy-duty truck traffic and the resulting high operating costs in open pit mines. This article presents the design and the initial findings of the feasibility study on the Chevron-Megapipe conveyor for a 350 m-deep open pit mine and a mass flow of 5000 t/h.

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.
