Keywords: Vibrating screen; mining industry; mineral processing 1. Introduction Frequent mining machine breakdowns are limiting the competitiveness of mining industries globally, which leads to fluctuating mineral market conditions [1], high cost of purchasing and maintaining machines [2-4].
Moreover, time series of stock prices are non-stationary and non-linear, making the prediction of future price trends much challenging. To address them, we propose a novel State Frequency Memory (SFM) recurrent network to capture the multi-frequency trading patterns from past market data to make long and short term predictions over time.
For example, assuming a shaft speed of 350 rpm, the inner fault frequency for bearing 1 is: 10.75×350 = 3762.5cpm= 62.70Hz. If the above frequency (or its harmonics) is present in the associated frequency patterns mined by SAFP, then there is …
