Damen shipyard upgrades cement carrier
16 January 2018Netherlands: The Damen shipyard at Oranjewerf in Amsterdam has upgraded the cement carrying capacity of the Lelie C owned by Cebo Marine. Eight new cement silos, with a capacity of 40m3 each, have been installed on the vessel alongside general maintenance.
The silos were previously fitted on the VOS Symphony prior to it going for scrap. Damen Shiprepair Oranjewerf removed the tanks, refurbished them and then installed them on board the Lelie C. The shipyard also built a silo foundation and fitted it in the vessel’s hold. 80m of stiffeners were welded into place in the double bottom tanks to provide the necessary support. Alongside this, approximately 100m² of grating walkway was fabricated and fitted on the deck to give access to the manifolds on each of the new silos. The supply and discharge and air pipe system for the two existing silos was also refurbished to accommodate the new capacity.
“Two years ago we installed the original tanks from the Ritske, a vessel belonging to the same client, and now we have repeated the process again, this time on a much larger scale. The Lelie C began her life as a general cargo vessel, but now her transformation into a cement carrier is complete,” said Jeen van der Werf, Commercial Manager at Damen Shiprepair Oranjewerf.

Dangote Cement building upgrades at Mugher plant in Ethiopia
13 February 2017Ethiopia: Dangote Cement is building a bagging plant and a third silo at its Mugher cement plant. The US$19m bagging plant will have a capacity of 120 million bags/yr, according to the Ethiopian Reporter newspaper. It is scheduled for completion by July 2017. The silo should be completed by the third quarter of the year.
Deep Kamara, the managing director of Dangote Industries Ethiopia, also said that the company is considering building a second production line in the country. However, procuring spare parts is proving difficult for the plant due to shortages of foreign currency and delays in shipping new parts. The company is expecting help from the government and it needs to spend up to US$15m on spare parts for the plant.
The Mugher cement plant opened in 2015 with a cement production capacity of 2.5Mt/yr. Equipment at the plant was set on fire in late 2016 in a series of riots in the region.
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.
Qatar: Qatar Primary Materials Company (QPMC) plans to inaugurate its new cement silo project in the first quarter of 2017. The project is located at the Port of Mesaieed and includes two cranes, two conveyor belts, 12 silos each with a storage capacity of 5000t and a total of 60,000t, according to the Gulf Times newspaper. The silos will have a discharge rate of 250t/hr with a total of 1000t/hr. QPMC’s chief executive Eisa al-Hammadi said that the silos were to ensure a ‘sustainable’ supply of cement in the country. The site is intended to store and discharge over 2Mt/yr of cement.
QPMC completed its Bulk Materials Handling System in late 2016, a 4.8km conveyor belt system connecting the Port of Mesaieed to storage areas. The conveyor operates at a speed of 3m/s allowing material to be transported to the destination in under 30 minutes. The building materials distributor says that the conveyor is the first in the Middle East and one of the longest in the world.
