Cuba: A ‘materials spill’ at Cementos Cienfuegos’ Carlos Marx cement plant in Guabairo on 27 August 2024 resulted in the death of one worker and injuries to five others. General manager Ernesto Gálvez said that a filter in the plant’s Kiln 3 collapsed, leading to the spillage of hot material from a hopper. Granma News has reported that Raymundo Narciso Sarría, an employee of contractor Empresa de Construcciones Ingenieras No. 6, died, while one other worker is in a critical condition, two in a serious or very serious condition and two others in a less serious condition.

West Africa: Germany-based InterCem has successfully despatched its second InterHop hopper to West Africa. The hopper will handle clinker and raw materials for an unnamed customer there. The supplier says that the equipment offers an unloading rate of 14,400t/hr. It produced it in the UAE.

Sweden: UK-based Samson Materials Handling is supplying an Eco Hopper product for installation at the Port of Slite in Gotland. The hopper will be designed to receive clinker, limestone, coal and refuse-derived (RDF) fuel pellets. These materials will be unloaded at the quay area via crane grabs. The hopper will then discharge direct to trucks via a telescopic chute.

The Eco Hopper installation under normal operating conditions and based on the client’s grab sizes and cycle time, will achieve peak discharging rates of: 353t/hr - based on clinker with a bulk density of 1.4 t/m³; 454t/hr - based on limestone with a bulk material density range of 1.8 t/m³; and 420t/hr - based on RDF Pellets with a bulk material density of 0.6 t/m³.

The Eco Hopper product design concept comprises of a specialised reception hopper unit incorporating Integral filter arrangement with a reverse jet filter media cleaning system which returns all material back in to the material stream. In addition, the inlet system of the hopper is based on the Samson Flex-Flap design which reduces the volume of air necessary to control dust both from the opening grab and displaced air from material falling into the inner hopper below. This contributes to the reduction of airflow reducing filter and power requirements of the equipment.

Commissioning and operator training will be provided by Aumund Group Field Services.

Kenya: Samson, a subsidiary of Aumund Group, has delivered four hoppers with ATEX certification to the Port of Mombasa operated by the Kenya Port Authority. The new equipment will be used to import clinker, coal and gypsum to the site. Peak rates of 700t/hr per hopper are expected to considerably improve the import capabilities of the port.

The hoppers are decked with inlet grills with suction capacity, a reverse-jet cleaning system, air compressors, a flex-flap filtration system creating a pressure differential between the inner and outer hopper areas and dust filters on three sides of the hopper. The hoppers are mobile with powered travel and crabbing functionality which lets them be positioned alongside a vessel for unloading and which will allow them to be manoeuvred off the quay and freeing up space when not required. Samson says that these are the first ecological hoppers to be provided with ATEX certification.

This equipment was sourced to fulfil the aims of TradeMark East Africa - Kenya Port Authority Port Resilient Infrastructure Programme to improve port facilities whilst minimising the environmental impact of port operations.
