Centerless grinding operates on the principle of removing material from a workpiece without the need for a center point. It involves a centerless grinding machine with two grinding wheels, one fixed and the other adjustable. The workpiece is placed between these wheels, and the adjustable wheel, known as the regulating wheel, exerts …

Abstract. Industrial grinding circuits are known to be extremely complex and difficult to model. We present a novel approach for data driven modelling using Recurrent Neural Networks (RNN) for enabling surrogate assisted nonlinear feedback control of grinding circuits, leading to energy sustainability in mineral processing industries.

With the in-feed method, the regulating wheel spins the part at one speed while pushing it towards the grinding wheel, which is spinning at a faster speed. The greater the difference in speeds, the faster the removal rate. 4. The choice of grinding wheel is critical. Another key factor in centerless grinding is the choice of grinding wheel.
