Pioneer Cement to install four Loesche mills

Published by
World Cement,

Loesche is to supply four vertical roller mills (VRMs) for a new cement production line at Pioneer Cement’s plant in Chenki/Khushab region of Punjab province, Pakistan. The new line will expand the plant’s production to around 8000 tpd.

The four VRMs will be used for grinding cement raw meal, clinker, and coal, Loesche said in a press release. The raw meal mill will have throughput of 630 tph; two cement mills will have a processing capacity of 235 tph each; and the coal mill will have a capacity of 60 tph.

The raw meal mill will also be supplied with a HURRICLON cyclone technology from Loesche subsidiary, ATEC. According to the German engineering company, “HURRICLON technology plays an important part in reducing the total energy requirement of the plant, due to the low pressure loss and high degree of separation.”

In addition, the HURRICLON system reduces the steel construction and installation costs, as a result of its lower weight compared to conventional cyclone technology.

Loesche Dynamic Classifier (LDC) is already used in the plant and will ensure appropriate fineness in the cement grinding circuit. “The patented vortex rectifier and optimised flow characteristics [of the LDC] produce significantly lower energy consumption and therefore lower operating costs,” the company said.

The order was placed through Chengdu Design & Research Institute, part of Sinoma International Engineering, which has been contracted to install the plant. Following installation of the VRMs, a total of 32 Loesche mills will be located in Pakistan.
