Hello Raju, Since both are a measure of particle size, residue is normally linked to Blaine But not always It depends on the particle size distribution of the cement and this is driven by several things including mill design, ball charge (or grinding pressure in a roller mill), clinker hardness, gypsum content, and the quantity and hardness of mineral fillers used (eg limestone)Residue Curve Principle A residue curve describes the change in the composition of the liquid phase of a chemical mixture during continuous evaporation at the condition of vapor–liquid equilibrium (open distillation) Multiple residue curves for a single system are called residue curves map Residue curves allow testing the feasibility of a separation of mixtures and Residue curve Wikipedia2017年9月11日 In this study, an extensive sampling study was carried out at vertical roller mill of ESCH Cement Plant in Luxemburg Samples were collected from mill inside and around the circuit to evaluate the (PDF) Performance Evaluation of Vertical Roller Mill in Cement Figure 82 shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier This is a normal setup as the primary function of a rod mill is to provide a uniform sized feed to the ball mill Figure 83 shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the ball mill whose primary function is OpenCircuit Mill an overview ScienceDirect Topics
