The mill is guaranteed to achieve capacities of 132t/hour pure slag, ground to 5000cm²/g acc. to Blaine, and of up to 200t/hour CEM II, ground to a fineness of 3500cm²/g acc. to Blaine. The mill main drive is designed for an installed power of 4600kW, and the SLS 4750 BC high-efficiency classifier, mounted on top of the MVR mill, enables high material fineness degrees of up to 5000cm²/g acc. to Blaine.

In addition to the MVR mill the contract includes handling equipment, two in-feed devices to enable moist slag and dry clinker to be fed to the mill separately, the plant filter, the plant fan, the magnetic drum separator and all ductwork including chutes, expansion joints and the stack. The scope of supply also includes a hot gas generator for the heating of the mill, as well as all electrical drives, starters, frequency converters and the electrical switchgear.

Zimbabwe: Production at the Redcliff cement plant is set to start in February 2017. China’s Mortal Investments Manufacturing has built the plant for a cost of US$20m, according to the Zimbabwe Daily. The plant will operate as Livetouch Cement and it will have a production capacity of 0.4Mt/yr. The project is currently waiting for clearance from the International Organisation for Standardisation (ISO) and an Environmental Impact Assessment (EIA) from Environmental Management Agency. Once operational the plant will produce 22.5 grade cement using locally sourced slag.

Zimbabwe: Mortal Investments Manufacturing Company expects to complete construction of its US$10m cement plant in Redcliff by the end of October 2016. The Chinese investor started construction of the project in August 2016 and testing is set to begin by the end of October 2016, according to the Business Chronicle newspaper. Commissioning is scheduled for the end of 2016. The plant will use slag to make its cement.

France/Ireland: According to the Irish Independent newspaper, Irish cement company Ecocem has invested Euro30m into a new production facility in Dunkirk in the north of France as part of joint venture with the world's largest steel company. The investment is split 30% to 70% in favour of Ecocem and will increase the Irish firm's capacity from 1.4Mt of high performance, low carbon cement to around 2Mt. Ecocem said the main target markets for the plant will be the north of France and the UK.

ArcelorMittal, the company that is investing with Ecocem, is the world's largest steel firm. The investment is a strategic partnership as Ecocem uses a by-product of the manufacture of iron and steel - Granulated blast furnace slag - to make cement.

The news follows recent builds by the company with the Peel Ports Group. The pair built an import terminal in Runcorn on the Manchester Ship Canal and will look to add to it with another two, one in Runcorn and another in Sheerness in England.
Ecocem's continued expansion in the UK is a response to growing demand from the market. The firm has experienced an increase in exports from the UK as a result of a bustling cement market and a shortage of the type of cement Ecocem produces.

Speaking at the time of its UK investment, Ecocem managing director Conor O'Riain said the firm is looking long-term at the market. "We've invested in state-of- the-art equipment to demonstrate to the market that we're here for the long term, and I'm delighted to say that the response from the market has been phenomenal. We've made commitments to sell more in the UK in our first year than our total domestic sales in 2016," he said. Prior to entering the British market Ecocem had already received orders for 200,000t of product for its first year and stopped taking any further offers in the short term.

Ecocem is also trying to make its first move into the US. The company is looking to build a Euro45m grinding mill near San Francisco but has some hurdles to its intentions from its planning applications.

The firm has continued to grow its reputation as a low-carbon cement producer and last month the firm picked up the Green Product Award 2016 for its superfine product.

Indonesia: PT Krakatau Semen Indonesia has ordered a slag grinding mill from Loesche for its Cigading grinding plant in Cilegon, Banten. Krakatau Semen will use a Loesche mill with an LDC classifier to grind ground granulated blast furnace slag to a fineness of 4500cm²/g. The scope of supply for this contract also includes the raw material transport system, the mill dust extraction system, the reject system and the silo equipment. The mill is scheduled for operation by the first quarter of 2017.

Subsidiaries of Loesche are participating in the contract. Loesche ThermoProzesstechnik is supplying the grinding plant with a hot gas generator type LF-36L (fully inline) for the combustion of industrial diesel oil. Automation of the plant is supplied by Loesche Automatisierungstechnik. Loesche Indonesia will provide a service contract including personnel services. In addition, Loesche will monitor the local production as well as the assembly and commissioning.

PT Krakatau Semen Indonesia was founded in November 2013 as a state-run company. In a joint venture with PT Semen Indonesia, PT Krakatau Semen Indonesia is building its first plant of this type with a planned production of 0.75Mt/yr.

UK: Lucideon has benefited from a newly published standard by the British Standards Institution (BSI) for alkali-activated cementitious material and concrete. The materials technology company has been developing and applying its proprietary MIDAR technology based on alkali-activated cements for several years. A recognised building standard gives it a stronger route to market in Europe.

“With the help of our materials experts, manufacturers can develop products using alkali-activated cement technology. This could potentially improve the performance and reduce the raw material costs and carbon footprints of products,” said Rebecca Law, a development scientist at Lucideon.

Lucideon develops materials technologies for a range of industries including construction, healthcare and nuclear sectors. MIDAR is a technology that binds alkalis and aluminosilicate materials, such as those from waste streams including fly ash and blast furnace slags, to form a rigid inorganic material. This technology can be used to make solid or aerated building products.

US: The US Department of Labor Occupational Safety and Health Administration's (OSHA) Cleveland Area Office has cited Essroc Cement for one repeated and 10 serious safety and health violations at its site in Middlebranch, Ohio. OSHA found that the company had exposed workers to machine, noise and respiratory hazards following an investigation started in November 2015 after a complaint was submitted alleging unsafe working conditions. The US subsidiary of Italacementi faces fines of up to US$92,000 for the violations.

"Employers have a responsibility to protect workers from exposure to noise and respiratory hazards that can lead to debilitating health conditions," said Howard Eberts, OSHA's area director in Cleveland. "Essroc needs to immediately re-evaluate its safety and health programs to keep workers safe on the job."

Essroc operates a slag grinding plant and a cement terminal at the site.
