Hot, hotter, JOEST!

JOEST supplies a spiral elevator for active carbon with a feed temperature of up to 300° C.

In June 2018, JOEST sold an approximately 7 meter high spiral conveyor to a customer in the Netherlands. The customer’s goal was to cool the product feed temperature, which is up to 300° C, to a maximum of 60° in the conveying process.

First activated carbon is added directly from an upstream process in the spiral conveyor. The product with different quality levels can be entered into the conveyor via two material feeding units.

For better wear protection, the inlets and outlets are exchangeable.

The sections of the spiral, called flights, are combined in several circuits and connected to the cooling water supply, which provide for a temperature reduction. JOEST has provided a connection for customer dedusting of the product space in the spiral conveyor. Since the product can be flammable, the customer has additionally opted for an Atex certified version.

The spiral conveyor has a non-stationary, resonating cladding that has been painted with a special heat-resistant coating. This cladding has been equipped with side inspection openings for better accessibility.

A particular challenge was the assembly at the premises of the customer. The spiral conveyor had to be incorporated into an already existing steel construction. For this, the cladding had to be retrofitted to the spiral conveyor. Since the customer operates his production fully continuously, only a small time window was available, which JOEST had to meet for the assembly.

Since November 2018, the spiral conveyor has been used by the customer in production and runs to the customer’s complete satisfaction.

Resonance Conveyor for Slag

The high requirements of waste to energy plants as well as systems with low energy demands are no novelty for JOEST.
With these resonance conveyors for Hitachi Zosen Inova, the material can optionally be fed to another unit via an intermediate opening with integrated JOEST Grizzly Screen. Another highlight is the low drive power of only 4 kW.

Lithium Process
Equipment

In recent years, JOEST Australia has increased its footprint within the Australian battery metals industry. JOEST Australia has delivered a package of 20 new machines comprising 18 different sizes and configurations, from dry scalping and sizing through to wet screening applications, to process the spodumene ore used in the conversion process to yield lithium hydroxide for the expanding battery industry. Due to the project‘s specific requirements, JOEST Australia personnel worked in close collaboration with the customer’s process design team to optimise the feeding and screening equipment used in this latest landmark greenfield project.

Technically most modern iron ore mine worldwide

Recently, JOEST Australia has successfully supplied and commissioned its largest single package of machines, under contract to a major iron ore supplier. This contract comprised seven double deck multi-slope screens and vibrating feeders. The customer’s iron ore processing facility is purported to be one of the most technically advanced iron ore mines in operation. The collaboration of JOEST Australia personnel with the customer’s Engineering Procurement Contract Managers (EPCM) enabled the condition monitoring for the equipment package to be integrated into the plant process control.

JOEST System Solution for dry ice dosing

To dose dry ice pellets from their transportation boxes into special isolation containers, JOEST delivered a system solution to the global specialist ASCO Carbon Dioxide this year. Realistic tests at the JOEST Test Center gave insight to the handling of dry ice at extremely low temperatures – at standard pressure -78°C – and the effects it has on the equipment. This data was analyzed by product specialists at JOEST and implemented in the details of the engineering design. The client’s demand was to dose the dry ice pellets with high precision, but without destroying them. A big challenge was the large difference in temperature between the product and the environment. Varying transportation boxes on the feed end, adjustable batch sizes and intermediate storage of the box volume were additional features demanded for the system solution.
