Malaysia: Engineering company Christian Pfeiffer has released more information about a grinding plant that it completed at the Mambong cement plant for Cahya Mata Sarawak (CMS) in 2016. The engineering procurement and construction (EPC) contract was originally signed in mid-2014 and it also included raw material handling, finished product storage silos and an automated packing plant.

The grinding plant consists of a two-compartment ball mill with a diameter of 4.8m x 15m effective grinding length equipped with a QDK 248-Z separator designed to produce 150t/hr of cement with a fineness of 3500cm²/g according to Blaine. The mill is supported by slide shoe bearings and driven by a lateral drive unit consisting of a girth gear and two pinion gear box with a floating shaft and a 5600kW main motor. The feed materials - clinker, gypsum and limestone - are dosed separately via weigh feeders, while fly ash can be added directly to the separator by a bucket elevator.

The ball mill is equipped with progressive lifting and classifying liners and filled with Allmax grinding balls. The material flow from the first to the second compartment is regulated by a Christian Pfeiffer intermediate flow-control diaphragm in Monobloc design, to ensure an ideal material level and particle size for fine grinding in the second compartment. The fine ground cement leaves the mill by a discharge diaphragm, in a Christian Pfeiffer Monobloc design, and is fed to the separator circuit by a bucket elevator. Separation of the ground cement is achieved by a bag filter application with minimum remaining dust content in the clean gas of below 10 mg/Nm³.

The cement produced is stored in two interchangeable 10,000t silos. One is a mono-cell and the other duo-cell, allowing for the production and storage of three different types of cement. Each silo is equipped with two bulk loading devices for conventional silo truck loading. Cement for the adjacent packing plant is transported via air slides and a bucket elevator. There, it can be filled into big-bags or cement paper bags by a rotary packer at a rate of 3000 bags/hr. At this stage the single packed cement bags can either be directly loaded on trucks or be transferred to a palletiser. The automated palletising system is designed for both pallet and palletless operation.

CMS officially launched the 1Mt/yr grinding plant in late 2016.
