Precise feeding of process materials is critical to maintaining product quality, but measuring and ensuring steel raw material quality control can be challenging. We offer belt scales with a range of conveyor speeds and levels of accuracy. Our weighbelt feeders provide a consistent flow for blending or batching, from light materials at low feed rates to heavy-duty loads requiring faster feeds. Our online elemental analyzer helps monitor and control sintering process fluctuations, inhomogeneous mixtures, and other parameters that affect productivity, physical and metallurgical quality, and raw material consumption and costs.
Gain significant economic benefits for the iron ore sintering process and the blast furnace with the Thermo Scientific CB Omni Fusion Online Elemental Analyzer configured for the sinter feed application. Chemical composition is one of the most important parameters for the efficiency of the sinter process. The CB Omni analyzer for sinter measures sinter feed chemistry on-line and provides minute by minute, reliable chemical analysis data to enable control of basicity in real time.
Monitor your conveyor belt scale feed with high accuracy even in the most demanding industrial applications with Thermo Scientific Ramsey Conveyor Belt Scale Systems. Ramsey belt scale systems monitor steel raw material feed to crushers, mills, screens, preparation plants, and coal-fired power plants to help ensure precise feeding of process materials and maintain product quality.
Sinter is the primary feed material for making iron in a blast furnace. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace.
Sinter feed composition control is important because the various sinter feed materials are not perfectly characterized and their chemical makeup varies within a batch and between batches.
As the raw feed material chemistry changes, the additive feed rates should be adjusted to smooth out these variations in the sinter strand feed chemistry.
The basicity of sinter feed material is an important parameter in the efficient operation of the sintering and iron making process. Basicity is a calculated chemical parameter composed of the ratio of two or more elements that are known to affect the alkalinity of the material. Stabilization of the basicity of the sinter product delivers benefits not only to the sinter operations but to the downstream iron making process.
The CB Omni Online Elemental Analyzer can help control the sinter feed basicity and provide a more consistent feed to the sinter strand. The benefits of real-time chemical analysis data provided by the CB Omni analyzer include:

The CB Omni analyzer uses Prompt Gamma Neutron Activation Analysis (PGNAA) or Pulsed Fast Thermal Neutron Activation (PFTNA) to determine elemental concentration in bulk materials. The method is deeply penetrative and measures through many centimeters of material making it an ideal technology for real-time elemental analysis of bulk materials on conveyor belts.
