2 Pyro Research and Test Center
Metso’s Pyro Research and Test CenterBackgroundMetso designs, engineers and manufactures equipment and systems that increase the economic value of ores, minerals, waste and related materials by changing their mechanical and/or chemical properties through the addition or removal of heat.
Our Pyro Processing capabilities emerge from the technical know-how of:• KennedyVanSaun(KVS)• AllisChalmers• Stansteel• Pyrotherm• Armstrong• Holland• MPSI
Process design begins with an understanding of the feed material’s physical and chemical characteristics and ends with the Customer’s product specifications. Metso Minerals Pyro Processing takes these two endpoints and designs the equipment to go from the feed to the product. Pyro has experience with over 450 different types of ores,minerals,chemicalsandwastes.UtilizingRotaryKilnsandFluidBeds as the key processing equipment, Pyro designs and supplies complete systems, from feed to discharge, chute to stack.
The development of new products and the improvement of existing products and processes are the Metso Pyro goals to meet changing customer’s needs in today’s competitive market. To address these needs, Metso Minerals operates the Pyro Research & Test Center (PRTC).ThePyroResearch&TestCenterisafully-equippedfacilitywith the capabilities to perform complex material evaluations and
process testing, as well as simulating a complete pilot flow sheet. The Test Center is unique in its ability to pilot test a complete flow sheet with many different unit operations that can be assembled to representacommercialplant.Inaddition,MetsoMineralsprocessengineers are involved in the test work from batch feasibility studies and interpretation of pilot plant results to commercial equipment sizing, design, supply, installation and start-up.
The Pyro Research & Test Center is at the forefront of Pyro technology for the division’s worldwide leadership in developing energy- efficient, environmentally sound, and economic processes to extract and use the world’s vital natural resources, including the recycling of waste products and destruction of hazardous materials.
Typical processes investigated in continuous pilot plant circuits include both rotary kilns and fluid bed applications for drying, calcining, roasting, direct reduction, thermal conversion, soil decontamination and waste treatment.

Pyro Research and Test CenterThePyroResearch&TestCenter(PRTC)isafullyequippedpyrotestfacility with the capabilities to perform complex material and pro-cess tests and evaluations, as well as simulating commercial flow sheets.
The Test Center is unique in its ability to generate a complete flow sheet with many different unit operations which can be assembled torepresentacommercialplant.Inaddition,MetsoMineralsprocessengineers are involved in the test work to prepare feasibility studies and interpretation of test results to commercial equipment sizing, design, supply, installation, training and start up.
Equipment available for tests• Mufflefurnaces• Batchdirectfiredrotarykiln-small&large• Indirectfiredbatchandcontinuouskilns• Panpelletizers• Pot-gratefurnace• Fluidbeds• Holo-Flites• Batchlimehydrator• Laboratoryfurnaces• Laboratorycrushers
The Test Center performs necessary test work for sizing and design of commercial equipment using bench, batch and continuous pilot plantscaletesting.TheTestCenterhasperformedover100Continuouspilottestssince1950tosimulatecommercialoperationsfor both private industry and government agencies.
The bulk of the materials that have been processed at the PRTC are naturally occurring minerals or ores such as coal, iron ore, limestone, and soils/clays/sands. Other materials that have been processed are tire shreds, plastics, petroleum coke, and simulated wastes.
Metso Limestone Evaluation (LSE)Purpose:The test is conducted to evaluate any given stone and these tests were developed and standardized by Metso, in-house. The results of the Metso stone evaluation may well mean very little to someone outsideofourorganization.However,becauseMetsohastestedover900stonesandhasalsobeenabletowitnesstheperformanceof many of the stones in various types of kiln systems, we have developed quite a “baseline” for evaluating potential kiln feed material.
AlthoughtheMetsoevaluationdoesprovideanindicationofseveralstone characteristics, the primary use of the evaluation is to determine how much the stone will physically breakdown during thecalciningprocess.Aseachstyleortypeofcalciningsystemiscapable of handling a certain maximum amount of fines/dust, this information plays a vital role in choosing the type of kiln that is appropriate for the application.
