Stacking, Blending & Reclaiming
Stockyard Machines for Coal Handling
|
A little unexpectedly, coal has become something like the fuel of the future. This can also be seen from the large number of projects for coal handling facilities world wide. Most of the times, stacking and reclaiming equipment forms a major, and often quite impressive part of these facilities. This article provides examples of such equipment for handling of coal from Sandvik Mining & Construction. |
Plant Automation
Always on Top- Cranes for Automatic 24-hour Operation in Refuse Incineration Plant
|
The conversion of two refuse cranes into fully automatic systems marks the first 24/7 solution implemented by Demag Cranes & Components in Copenhagen, Denmark. The additional use of a scanner-guided height measurement system also achieved a significant increase in handling capacity. |
Silo Technology
Large Screw-Floor Discharge in a Squat Steel Silo in Brazil - Flow and Pressure Analysis
|
In Brazil, a large multiple screw-floor discharge system has been applied to a squat steel silo with the purpose to dry Soya grains by means of aeration. The advantage is that aeration is applied to the hot grain coming from the dryer and continues to dry it in the silo. |
Stacking, Blending & Reclaiming
Automation for Bulk Handling Machinery
|
Due to their size, capacity and complexity todays bulk handling machinery can hardly be man-controlled. Furthermore, quality assurance demands the retraceability of the complete production process which can only be guaranteed by a completely controlled system. At the example of their own installations the author describes how modern automation systems work. |
Stacking, Blending & Reclaiming
Paddle Feeder Discharge Arms - A Study on Performance Characteristics
|
Rotary paddle/plough feeder performance and efficiency depends to a great extend on the shape of the plough. This paper provides calculations for the design of such feeders, illustrated by an example, to increase their capacity and lower the power consumption. |
Coal Handling
The NTPC Vindhyachal Coal Handling Plant
|
To improve the electricity supply of the country, India depends to great extent on coal as the power plant fuel. Following, the extension of a power plants coal handling system and the problems which needed to be solved are presented in brief. |
Silos, Bins & Bunkers
Silos for Pulverized Solid Fuels
|
Due to the latent hazard of formation of an explosive dust/air suspension in silos for pulverized fuels (PF silos), precaution is required. The protective technologies used are not uniform, but in certain industries, like the cement industry, a “state of the art” on a good level has developed and is widely accepted. There are different ways to arrive at the state of the art level. |
Ports & Terminals
Port of Ust Luga - A Modern Coal Terminal at Russia’s National Territory
|
In 2006, finalisation of the second extension project at the Port of Ust Luga lead to an annual handling capacity of 3 million tons of coal, and at the end of 2008 it will reach a capacity of 8 million. The paper provides an insight into this impressive bulk materials handling project, which, at the end, will create a port with an annual handling cpacity of 35 million tons of coal. |
Dust Control
Dust Collectors at Cement Terminals - Longer Filter Life and Easier Change-out
|
Bin vent dust collectors are important to the function , operational costs, and working conditions in cement terminals. This article presents two examples of how proper design of bin vent dust collection systems can improve not only working conditions, but also functioning and operational costs of cement handling facilities. |
Fire & Explosion Protection
How to avoid the "Big Bang" of Bulk Handling
|
Dust explosions in processes handling combustible materials are responsible for many deaths and injuries every year, as well as millions of pounds worth of damage to plant and equipment. In this article, explosion panel manufacturer Elfab Ltd, presents possible safety measures. In particular, they focus on venting, probably the simplest and most common course of action. |
