UK: Hanson is considering spending around Euro23m on building a new clinker mill and other improvements at its Padeswood Cement plant. At present the site use four mills that are only able to grind about 40% of the kiln’s output, according to the Daily Post. A second phase of the upgrade project, dependent on production levels being increased, is planned to rebuild a railway link to the plant.

Qatar: Qatar National Cement Company plans to commission two cement mills for its Plant 5 during the first half of 2017 to increase its production capacity to 5500t/day. Then, construction work on the kiln will be completed in the second half of the year, according to comments made by Salem bin Butti Al Naimi, chairman and managing director of the company, that were reported by the Peninsular newspaper. The company intends to increase its production capacity of washed sand and calcium carbonate to capture an anticipated rise in market demand. It also intends to sell its Plant 1 to Umm Bab following an agreement in mid-2016.

The cement producer’s revenue fell by 2.6% year-on-year to US$313m in 2016 from US$321m in 2015. Its cement sales volumes fell slightly to 3.7Mt during the period. Its net profit rose by 2.3% to US$130m from US$127m.

Myanmar: South Korea’s Yojin Construction & Engineering has placed an order for two cement mills from Loesche for installation in Myanmar. The order for a cement and slag mill is Loesche’s first in the country. The mills will be used at a grinding plant owned by Yojin Myanmar Engineering in Thilawa. They will each produce 75t/hr of cement with a fineness of 3300 Blaine. Operation is scheduled for mid-2017. Yojin is building its new grinding plant in the Thilawa Special Economic Zone south-east of Yangon. The site has an ambition to produce 1Mt/yr of cement.

Egypt: Hoffmeier Industrieanlagen has delivered a ball mill to Misr Beni Suef Cement. The mill has a diameter of 6m, a length of 17.3m and its weighs 190t. The installation of the mill will start in April 2017 and is to be commissioned by the end of the year. Hoffmeier will also support the customer with its installation knowledge during the assembly phase. The German engineering company produces industrial heavy machinery including tube mills and rotary kilns.

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.

Egypt: Misr Beni Suef Cement has delayed the installation of a coal mill at its Beni Suef plant to the third quarter of 2017. Farouk Mostafa, managing director of the company, said that the delay has been caused by a shortage of US Dollars needed to pay to import the mill and its spare parts and general currency variations with the Egyptian Pound that has raised prices, according to Daily News Egypt. The mill was originally planned for December 2016.

Georgia: Gebr Pfeiffer has received an order to supply a mill for HeidelbergCement Group’s Kaspi plant. The vertical roller mill will be used in a new 3000t/day kiln line at the site. The order was placed through the China’s Sinoma Chengdu in November 2016.

The type MPS 4000 B mill, equipped with a SLS 3750 B type classifier, has been designed for a capacity of 270t/hr of raw meal. The mill will be delivered with an enlarged housing to allow the raw material with a moisture of up to 10% to be dried almost exclusively with the available preheater gases.

Commissioning of the plant is scheduled for 2018.
