Abstract: The present invention provides a system and method for more efficient utilization of comminution mills. Sensors are provided in the liners placed within the mill shell. The sensors may include RFID tags, liner wear profile sensors (e.g., such as an ultrasonic sensor), an inertial sensor (preferably included both an inclinometer and an accelerometer, and an acoustic sensor, among others. When the liners are installed in the shell, the RFID tag is used to register the location of the liner within the shell. In operation, the information provided by the sensors is collected by a data transmission unit and sent by transmitter over the air to a computer having an antenna and receiver for such data. The data is correlated and the data is reviewable in real time while the mill is in running.

Abstract: The invention relates to a method for the production of martensitic cast steel of high strength and excellent abrasion- and impact-wear resistance, intended for large parts used as anti-wear cladding in crushing and grinding mining operations, having a chemical composition, expressed in percentage by weight, of between 0.35˜0.55% C, 0.60˜1.30% Si, 0.60˜1.40% Mn, 4.5˜6.50% Cr, 0.0˜0.60% Ni, 0.30˜0.60% Mo, 0.0˜0.70% Cu, 0.010˜0.10% Al, 0.0˜0.10% Ti, 0.0˜0.10% Zr, 0.0˜0.050% Nb, less than 0.035% P, less than 0.035% S, less than 0.030% N, optionally 0.0005˜0.005% B, optionally 0.015˜0.080% rare earths, and the rest being iron. The method for the production of cast steel includes smelting, pouring and heat treatment. The smelting can be performed in an electric arc furnace with acidic or basic refractory or an electric induction furnace. Smelting in an electric arc furnace as a normal operation includes melting, oxygen insufflation, blocking, refining and deoxidation.
