The amount of separator reject circulated back to the mill was 480 t/h with a circulating load of 370%. Download : Download full-size image; Fig. 2. The sampling point of the cement milling circuit.

    How to Improve Cement Ball Mill Performance in Closed

    The closed-circuit grinding system formed by a ball mill and a separator is a type of widely used cement milling system in cement plant. There are many factors that may affect the ball mill’s working efficiency and product quality during the operation. In this article, we will discuss the measures that can improve the ball mill’s performance.

    PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL

    A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at

    Open and closed circuit dry grinding of cement mill

    Mill capacity and the stirring speeds were the investigated parameters for the open circuit tests, whereas closed circuit tests were carried out at a constant stirring speed but variable discharge rate. Five speed levels used in the open circuit grinding tests are 200, 400, 600, 800 and 1000 rpm. The capacities were determined to obtain product Blaine surface areas in the limits between 2000 and 5000 cm 2 /g. Closed circuit
