Müllerkalk opts for pneumatic conveyance with ceramic rotary valves

The operators of the Müllerkalk and Wotan cement plants have decided in favour of four pneumatic conveying systems by bulk handling equipment manufacturer Kreisel. This article describes the project from its first planning phase through its final implementation.

1 Introduction

Portland cement producer Wotan Zement and lime supplier Müllerkalk are both medium-range, fami-ly-owned enterprises located in Üxheim-Ahütte, in the Volcanic Eifel region. Their products are derived from limestone found in the Hillesheim limestone hollow.
