Coal Mining and Coal Power Generation
Improve quality control and ensure safe operation in the coal mine
From the mine to loadout—we’ve got everything you need to meet quality specifications and ship a more consistent, quality product. Thermo Scientific™ online elemental coal analyzers and blending software provide coal producers with accurate, reliable data to control coal blends and ensure on-spec batches. We also offer belt scales, weigh feeders, and sampling systems that provide the process information needed to manage your operation to its greatest efficiency while giving you and your customers the assurance that you are shipping—and they are receiving—the tonnages required. Create a safer environment for your workers and protect your equipment with our tramp metal detectors, level sensors, belt misalignment switches, emergency pull switches, plugged chute switches, and personal dust monitors.
Products used in coal production
Minimize variations in coal quality, ensure contract compliance, and improve efficiency with the Thermo Scientific CQM FLEX Coal Analyzer. The CQM FLEX is a full-featured analyzer that can incorporate either Prompt Gamma Neutron Activation (PGNAA) or Pulsed Fast Thermal Neutron Activation (PFTNA), and it provides the option of sourcing the neutrons from traditional Cf-252 radioactive sources or via an electrically driven neutron generator.
Facilitate sorting, blending and out-of seam dilution control with the Thermo Scientific ECA Elemental CrossBelt Analyzer. The ECA is a Prompt Gamma Neutron Activation (PGNAA) analyzer designed to mount around an existing conveyor belt and analyze the composition of the total burden of coal on the belt in real-time.
Blend up to six coal sources to meet quality specifications at the lowest cost. The Thermo Scientific COBOS Coal Blend Optimization System controls coal sorting and blending operations with software that continuously monitors coal quality.
PGNAA and PFTNA help ensure coal blends meet specifications
In the coal blending process, different quality coals are mixed to meet requirements for particular applications. Blending decisions impact the total amount of each product that a mine site is able to sell, so it is important that the blended coal meet quality specifications.
Online and At-Line elemental analyzers are used to measure the composition of coal in real-time and proactively address process variations to ensure more consistent coal blends. The analyzer mounts around an existing conveyor belt or adjacent to a main conveyor with an in-line sampling system to continuously monitor coal quality. When combined with coal blending software these unique instruments offer the most effective way to minimize variations in coal quality, ensure contract compliance, and improve efficiency.
Online and At-Line coal analyzers utilize an analysis technique termed either Prompt Gamma Neutron Activation (PGNAA) or Pulsed Fast Thermal Neutron Activation (PFTNA) technology. These technologies are deeply penetrative and measure the entire material volume travelling by conveyor at a high frequency, making them ideal technologies to help ensure that all the coals in the supply mix are properly blended.

Belt conveyer scales are an important part of a mining operation’s bulk material handling system. A belt scale system monitors production output and inventory, or regulates product loadout, while providing vital information for the effective management and efficient operation of your business. There are many options to consider when selecting a belt scale system. How do you know which one is right for your application?
