BEUMER Group offers robust belt apron conveyors: Economic transportation of cement clinker

Tue, 30 Apr 2019 22:34:05 +0000

Robust apron conveyors (SZFs) are used in cement plants to transport clinker safely and economically from the kiln cooling system to the silos. BEUMER Group is the only manufacturer who offers a special variant, the belt apron conveyor (GSZF): Using a belt instead of a chain as traction element allows higher speeds and a slimmer design while still delivering the same level of performance. The GSZF is therefore particularly suitable for modernisations. In general, the clinker comes out of the cooler at 80 degrees plus ambient temperature. But during the process, a so-called kiln flash can occur caused by a raw meal flash from the preheater tower or by caked clinker coming off the kiln: Within a few seconds several tons of raw meal or clinker shoot through the cooler. The material to be conveyed cannot cool down sufficiently and reaches the conveyor at temperatures of 500 to 800 degrees Celsius. With its apron conveyors, BEUMER Group provides robust and reliable solutions. The specific design of the cells allows safe, low-friction transportation of any hot material. Sealed and overlapping side walls and bottom plates in the cells prevent the clinker from exiting and minimise the escape of dust. The traction element in this conveyor is usually a single or double strand sprocket chain. The system supplier is the only manufacturer on the market who offers apron conveyors with the tried and tested BEUMER steel wire belts from the bucket elevator technology instead of a chain as traction element. Here the cells are attached to the long-lasting, steel-wire reinforced belt in a way so that the heat of the clinker in the steel cells is not transferred to the belt. Partition plates are attached in the feeding area below the cooler and can be easily removed for maintenance, protecting the belt against hot clinker in case of a kiln flash. One decisive advantage of the belt apron conveyor: with speeds of 0.6 metres per second, it can reach double the conveying speed compared to apron conveyors with a chain. This makes it perfect for retrofitting and modernisations. If operators want to increase the kiln capacity for example, they can replace an existing chain apron conveyor with a belt version of the same size – this means double the capacity without having to make any changes to the steel structure or the conveyor bridge. The cement plants also benefit from a new construction application: The thinner, lighter design of the GSZF reduces costs for steel structure and freight. Furthermore, the decreased net weight lowers the static and dynamic loads which affect the clinker silo and foundations for example. A new construction project can be designed for a smaller load and is therefore more cost-effective to build. The lightweight design also lowers operational costs. Quiet, low in maintenance, reliable The entire belt lies with its surface on the drive and return pulley which avoids the unwanted polygon effects caused by the chain. The particularly smooth running of the machine also reduces noise emissions considerably. The noise is less than half as loud as conventional SZFs with chains, which is advantageous for both the employees and the environment. The use of the durable BEUMER steel wire belt lowers the maintenance costs, and extends maintenance intervals. Chains can break, if preventive maintenance is not performed properly, which will lead to the conveyor collapsing. The rubber of the steel wire belt only becomes brittle with age, but it would never completely break. Lubrication is also not required for the belt, whereas used frequently on a chain, if for no other reason than to reduce noise levels. Grease and oil are not only a cost factor, but also detrimental to the environment and the conveyor. The clinker dust gets stuck on it and settles in the chain links, which accelerates the wear and tear.

What lighting does your lift truck need?

Machinery is involved in more than 30% of the most serious industrial accidents. Visibility plays an important role in this. Also for you, as a forklift driver, it is important to be sufficiently visible on the shop floor. So don’t just make sure that you have a clear view of your surroundings, but also that nobody loses sight of the vehicles in and around your company. In function of the safety and visibility on the shop floor, we provide you with a number of guidelines to optimize the lighting of your forklift truck. Which work lights are mandatory? Legally speaking, your forklift truck must be equipped with a lighting system that sufficiently guarantees the safety of the employees during the work to be carried out. The most obvious solution is to mount LED or halogen lights on the fork carriage or overhead guard. This way, you have an amply illuminated zone in front of the forklift truck. Good front and rear lights make you easily visible, even in dark areas such as warehouses. Can you use your lift truck on public roads? Yes, but you have to observe the traffic regulations with your forklift truck. There are also a number of other conditions attached. First of all, a number plate with number plate lighting is mandatory. Furthermore, your forklift truck must be equipped with: Both dimmed headlights and parking lights at the front Indicators at the front and rear Hazard warning lights Red reflective triangle at the rear Two rear lights Two brake lights At least two reflectors Finally, all lights must have an E-marking in order to be allowed on public roads. Make your truck even safer with projection warning lights The standard equipment for your forklift truck ensures that you as a driver can clearly see where you are driving. Meanwhile, various projection warning lights have been launched onto the market that also warn pedestrians for an oncoming machine. Blue spot warning lights By means of a red or blue spot on the floor in front of or behind the forklift truck, everyone can see the machine coming before you come around the corner. The blue spot is a safety light that you can easily mount on top of the machine. Red zone light With a light that marks out a red zone along the machine, you can demarcate a safe distance for everyone in the workshop. This light can also be mounted in combination with the blue spot. By combining these warning lights, you create a safe zone in the front, back and on the sides. Do you wish to know more about lights?
