Switzerland: Switzerland-based ABB is launching the ProKiln inlet gas sampling system to help cement producers reduce the volatility associated with using higher levels of alternative fuels (AF) and allow kilns to run for longer. The product offers probe cleaning with increased mechanical strength, which includes a dual probe retraction system to ensure no sampling interruption.

The supplier says that its product uses an extractive filter in the tip of the probe which separates sample gas from the dust load to reduce problems faced with scaling of material when gathering data. It also uses two air blasters to clean the tip to maintain a sample path for analysis. A three-dimensional printed stainless steel nozzle is intended to ensure that no blockages at the tip of the probe occur and the system is mounted on a buggy running on a retractor which carries the probe in and out of the kiln allowing it to be cleaned automatically. Measuring 3m long, the gas probe is water cooled with an extractive filter placed at the sample and flow is maintained by the blasters. A cooling system also provides recirculating water for temperature control.

The ProKiln has been tested for six months at Holcim’s Lägerdorf site in Germany, a cement plant that has an AF substitution rate of over 80%.

Germany: Vecoplan has launched the VRZ 2500 shredder and the VPC 1600 pre-shredder, which can be combined with the VHZ single-shaft shredder.

The new addition to the VRZ series is intended for recycling and reprocessing waste wood. The unit is equipped with sickle-shaped ripper teeth and is intended for minimal maintenance through the use of HiTorc direct drives. The drives have a capacity of 2 x 138kw and are resistant to tramp materials. They are also dynamic, offering improved start-up and reversing behaviour. “During the development of the new VRZ series shredder, we placed great emphasis on making it robust, resistant to intrusive materials, reliable and low-maintenance,” said Martin Baldus, Head of Industrial Shredding development at Vecoplan.

The VPC 1600 is a pre-shredder intended for use with voluminous objects and bulky wooden items such as pallets. Notably, the new version of this product can be combined with the VHZ single-shaft shredders (VHZ 1600 and VPC 1600) to increase throughput by up to 50% and to save space. With its working width of 1600mm, the 800mm-high VPC is designed to fit exactly onto the VHZ with a sliding frame connecting the shredder and the pre-shredder. The VPC is permanently fixed during operation but it is designed to be moved at other times if an operator has to change the counter-knives in the shredder. The filler port of the new pre-shredder measures 1605 x 1605mm and the drive power is 2 x 9.2kw. Sixteen counter-crushers have been integrated into the machine and it also has two independently running rotors, each with a speed of ten revolutions per minute.

Netherlands: N+P has reported the successful performance of Subcoal Pulverised Alternative Fuel (PAF) quality, a type of its refuse-derived fuel (RDF) pellet product, in a series of industrial tests at Mitsubishi Heavy Industries’ (MHI) Research and Innovation Centre. It says the fuel “achieved a stable flame” without support fuel on a 24MW burner. In the tests, Subcoal ground by a vertical roller mill to a fineness of 90% under 3mm, was fed using existing handling systems into the burner at a rate of 4t/hr. The Netherlands-based recycling company says this proves its suitability for 100% substitution of conventional fuels for industrial applications.

N+P has also introduced the PAF grade Subcoal product to some of its clients in the cement and lime sector. It intends to research how these producers can replace the last 10 - 40% of their fossil fuel load. The first trials are expected to be carried out from late 2020.

Austria: Untha has announced the supply of an Untha XR3000C mobil-e primary shredder to Austrian Tyre Processes. The supplier says that the model’s twin 132kW motors produce refuse-derived fuel of a homogenous 50mm size, suitable for further processing into a cement fuel additive.

Its director of global business development Gary Moore said, “With the world’s raw materials rapidly depleting – and businesses and consumers alike demanding more environmentally responsible solutions – this is a fantastic example of clever engineering and innovative thinking coming together to change the face of the industry.”

Austria: Andritz has announced its upcoming line of ADuro primary and secondary shredders. The shredders, which it says are ‘for shredding refuse-derived fuels and municipal solid waste, as well as commercial or industrial waste,’ become available in July 2020. Andritz said, “The Andritz automation tools can be tailored to individual customer needs and provide powerful capabilities to monitor machine behaviour and improve plant reliability.”

Hungary: Italy-based Entsorga has completed the installation of an automated alternative fuel (AF) line at a Hungarian cement plant. The plant is believed to be Nostra Cement’s 1.0Mt/yr integrated Kiralyegyháza cement plant, which in early 2020 received an AF fuel store expansion aimed at bringing AF substitution rates to 80% from 60%. The upgrade consists of an Entsorga Spider crane and Pelican power system which will be able to maintain a continuous feed to the plant’s calcination system 24 hours a day.

Entsorga CEO Francesco Galanzino said, “Bringing a commission to a successful conclusion in the middle of the maximum intensity period of the coronavirus crisis has been a great satisfaction. The cement plant will make significant savings in CO₂ emissions.”

US: Geocycle North America has received a new Untha XR mobil-e waste shredder at its plant in Dorchester, South Carolina. The mobile unit with 2 x 177hp motors, will process non-hazardous post-industrial waste to produce refuse-derived fuel (RDF) for LafargeHolcim’s Holly Hill cement plant. The shredder is currently configured to manufacture 10t/hr of RDF and the plant aims to generate 35,000 – 40,000t/yr of the fuel. Untha says that the new product replaces a previous shredder from another manufacturer.

Finland: Metso has launched two new pre-shredders in its K-series. The new products are intended for sites with production requirements between 5 – 45t/hr. They are intended for market development in Asia. Particular features of the K-series include: both a synchronous and asynchronous shredding system with two shafts; a knife geometry that the company says reduces the risk of wrapping on the shafts; a modular system; and a build that allows easy access for maintenance.

Ecuador: Geocycle has commissioned a XR3000C mobil-e type shredder from Austria’s Untha for its Guayaquil operations. The product will be used to process various waste streams including plastic, paper and wood from industrial waste producers to support cement production. Biomass and municipal solid waste (MSW) processing is planned for the future.

“With Untha’s help, we’re helping Ecuadorian businesses transform waste into ‘ready for co-processing’ materials. We’ve invested in flexible, high capacity, single step shredding equipment, supported with world-class engineering support, so we are extremely excited about this plant becoming fully operational,” said Dorin Pepenel, Geocycle Ecuador.

Belarus/Hungary/US: Italy’s Entsorga is working on alternative fuel projects for cement plants in the US, Belarus and Hungary. In the US it has signed a contract to supply a Pelican feed line at Argos Cement’s Martinsburg plant in West Virginia. It follows a long-term off take agreement in place with the cement producer to supply alternative fuels. The 60,000t/yr feed station is similar to a feed station already delivered in 2016 in Nazareth, Pennsylvania.

In Belarus the waste engineering company plans to install an alternative fuel feed line at the Krasno cement plant. Local subsidiary EntsorgaFin will define the material acceptance standards and provide the design for the fuel feed station and feed line.

In Hungary Entsorga was awarded a contract for the supply of an alternative fuels automated handling and feeding system in January 2019 with an unnamed global cement producer. It will provide its Spider and Pelican products to the end user. Commissioning of the plant is scheduled for early 2020.
