Provides standard tests as well as special customized testing
The Pyro Research and Test Center (PRTC) can provide standard tests as well as special customized testing. All test pricing and material requirements can be provided through the Danville PRTC manager upon request.
PRTC TEAMWORK is the ability to work together toward a common vision. It is the ability to direct individual accomplishment toward common objectives. It is the impetus for allowing common people to attain uncommon results.
At Metso we take care to ensure that your visit to our facility is a safe one for both you and our staff. The test center adheres to industrial codes as part of the Metso HSE strategy. The PRTC is permitted by the Pennsylvania Department of Environmental Protection for operation.
The test center is unique in its ability to pilot test a complete flow sheet with many different unit operations which can be assembled to represent a commercial plant. In addition, Metso's process engineers 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.
The Test Center
The test center performs necessary test work for sizing and design of commercial equipment using bench, batch and continuous pilot plant scale testing.The test center has performed over 100 continuous pilot tests since 1950 to simulate commercial operations for 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.
How it works
The Pyro Research & Test Center is at the forefront of pyro processing 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 and fluid bed applications for drying, calcining, roasting, direct reduction, thermal conversion, and soil decontamination and waste treatment.
Metso Limestone Evaluation (LSE)
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 outside of our organization. However, because Metso has tested over 900 stones and has also been able to witness the performance of many of the stones in various types of kiln systems, we have developed quite a “baseline” for evaluating potential kiln feed material.
Although the Metso evaluation does provide an indication of several stone characteristics, the primary use of the evaluation is to determine how much the stone will physically breakdown during the calcining process. As each style or type of calcining system is capable 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.
The impact crushability test gives a Work Index (W.I.) that can be applied to three types of crushers. For a primary gyratory crusher the W.I. can be used to determine the horsepower. For an impactor the W.I. is only used as indication of the hardness. For cone crusher applications the W.I. is used to rate the material to determine if a heavy duty or an extra heavy duty crusher is required.
The paddle abrasion test results are in the form of an Abrasion Index (A.I). The A.I. can be used to help determine whether or not an impactor is feasible for a particular application. For cone crushing and impactor applications, the A.I. can also be used to calculate the approximate liner life for the crusher.
The french abrasivity/crushability test gives an abrasivity index and a crushability index that will rate the material in comparison with other materials. The french abrasion test is mainly used to estimate hammer wear life in impactor applications. The crushability index is a measure of how easily the material breaks down. The test also includes the specific gravity or solid density of the material.
