Gravimetric precision dosing in the cement industry

Gravimetric dosing systems are classified by their short-term and long-term accuracies. In this market review the cement process requirements for precision dosing are discussed and the latest technology trends are presented.

1 Introduction

Cement production requires accurate metering and dosing of bulk materials in each production step from raw material grinding to cement grinding and finally to cement mixing and blending. The better the accuracy of the short and long-term feed rate, the more stable are the processes, the better the processes can be optimized and the higher the quality of the clinker and cement. Take, for example, the raw meal dosing as an example, with relatively short processing time, less than 30  s, for the material in the preheater, where high dosing accuracy is necessary for a stable...
