Development of a laboratory scale procedure for

The throughput capability of a high pressure grinding roll (HPGR), a critical process parameter, has been found to heavily depend on the sample type being processed. Existing HPGR test methods require the use of pilot machines and large sample quantities to assess the throughput characteristics of a certain ore type. Addressing the need for a laboratory scale HPGR test, a laboratory procedure

Modeling the contribution of specific grinding

2009-6-1  The interest in the evaluation of HPGR technology in hard rock grinding, especially for Vale’s green field projects, requires a suitable model for simulation of this type of mill. This paper discusses some of the elements of the development of a procedure for characterizing HPGR grinding and the implementation of a HPGR model in Modsim™.

A Review of the Modeling of High Pressure Grinding

Soon after the introduction of HPGR, Schönert (1985) was the first to publish the key parameters, in the form of equations, for the scale-up of HPGR. Those equations have been widely quoted by others. Throughput, power, and the specific grinding force are the three main scale-up factors required for sizing a HPGR machine.

Advanced modeling of HPGR power consumption

2021-3-1  CL by BNN can quite accurately model power draw of a high-pressure grinding roll. Abstract This study, for the first time, is going to introduce the boosted neural network (BNN) as a robust artificial intelligence for filling gaps related to the modeling of energy consumption (power draw) in the industrial scale high-pressure grinding rolls (HPGR).

Assessment and modelling of quaternary and quinary

The HPGR performance and modelling evaluation for quaternary and quinary applications were supported by a combination of laboratory-scale testing, pilot-scale testing and modelling work. Results obtained from the research showed that the HPGR is suitable for comminuting iron ore in open circuit quaternary and closed circuit quinary applications.
