Abstract

The article discusses the issue of determining the newly formed specific surface of the cement clinker taking into account the lateral surface of the seal area. When developing this technique, the assumption that the newly formed particles have a shape close to spherical, has been made. The obtained ratio determines the work that considers the formation of thecement clinker material new surface, depending on the size of the original and newly formed material. An arithmetic expression is given, defined as the minimum amount of energy that must be introduced into the deformation zone for the destruction of a cement clinker particle to occur. The presented technique is specified taking into account the fact that defects are introduced into the crushed material particle. Taking into account the fact that the grinding ball makes an impact in one cycle of its movement, the value of the newly formed surface of the material in the ball mill is determined in one hour of its operation.

Highlights

Portland cement is one of the main building materials used in construction
For fine grinding of cement clinker and additives, ball mills of various sizes are mostly used [1, 2, 6, 7]
From the relation (18), it is possible to obtain the condition for the cement clinker material destruction, which follows from the positiveness of the newly formed surface value: Q 12πμ2 (1 2μ2 )δ2 σR24 (19)

Summary

Introduction

Portland cement is one of the main building materials used in construction. At the same time, the production of Portland cement is characterized by both thermal and electrical high energy consumption [1, 2]. In view of the above-said, we obtain the expression that determines the formation of a new surface of the cement clinker material, depending on the original and newly formed material size.
