H.E.R.O (High Efficiency Resource Optimizer) Tunnel Kiln for Heavy Clay & Masonry Blocks & Bricks
Introduction – Clay Brick making
GRM Group of companies takes traditional production systems and applies the most innovative materials, the most recent technology and the most sophisticated process controls so as to ensure outstanding quality and maximum energy savings.
“A good start is half the battle”: that’s why GRM Group of companies carries out careful, accurate analysis and research on raw materials to identify the most efficient solution for each specific project.
Body preparation and forming
GRM Group of companies has an internal laboratory fully equipped with all the instrumentation needed to analyze and characterize raw materials and bodies.
Depending on the technological results of the laboratory tests, GRM Group of companies provides wet or dry-method body preprocessing systems and an extensive range of forming solutions, each designed on a case by case basis to meet the specific needs of the individual customer.
GRM Group of companies supplies every single machine on the production line .
Drying
GRM Group of companies offers its customers technical solutions that optimise energy consumption while providing outstanding production flexibility.
GRM Group of companies-designed drying systems are conceived to allow plenty of scope when it comes to adjusting primary and recirculation flows, the goal being to optimise cycles according to product type and car load layout.
The key feature of the GRM Group of companies drier is the forwards-backwards load movement with deflector cone; fully designed and built by the Group’s production facilities, its purpose is to maximise reliability and minimise maintenance.
Firing
Firing temperatures vary considerably between different clay types and are often quite critical.
During firing, bricks undergo a physical change. Clay particles and impurities are fused together to produce a hard durable and weather resistant product.
This is called vitrification. This is usually accompanied by further shrinkage and a colour change.
Temperatures vary greatly depending on clay type but are generally in the range of 900 – 1200degrees centigrade.
Obviously bricks cannot suddenly be subjected to these temperatures so firing is in three stages.
1. Pre heating – this ensures total dryness of the brick and utilizes combustion oilses in the kiln to raise the brick temperature. (Where wet setting has taken place great care needs to be take at this stage)
2. Firing - A fuel, usually natural oil, LPG, oil or coal is used to raise and maintain the
temperature to the required level over a few hours.
3. Cooling – Cold air is drawn into the kiln to cool the bricks slowly ready for sorting and packing. This air becomes hot and can be drawn off and recycled for use in the drying process.
The range of kilns designed and built by GRM Group of companies consists of refractory brick-built tunnel kilns (FTO) or prefabricated structure (FPO) tunnel kilns; both feature combustion systems with burners installed on the walls or in the roof and a combustion space between one pack and the next.
GRM Group of companies kilns are designed and built according to the customer’s specific plant engineering requirements and feature all the apparatus and instrumentation needed to ensure optimisation of consumption and compliance with product-specific process requirements.
GRM Group of companies designs and produces all the burner types installed on its kilns, thus ensuring comprehensive process control.
Loading/unloading and packaging automation
GRM Group of companies designs and produces cutting-edge plant engineering solutions for each product handling stage, using both conventional Cartesian and robotized systems that adapt perfectly to the specificity of the individual product or plant.
Making the difference...
GRM Group of companies’ substantial R&D capacity is guaranteed by three internal in-plant labs, all fully equipped for the analysis and development of numerous applications in the heavy clay world.
Through these internal facilities GRM Group of companies meets and fully satisfies all the needs and requirements advanced directly by customers. And thanks to smooth synergies with Group companies, GRM Group of companies provides complete turnkey plants for the heavy clay brick industry that cover everything from body preparation to palletization.
Anytime, anywhere, customers can always count on GRM Group of companies’s outstanding heavy clay know-how
It’s time for a H.E.R.O Tunnel kiln (High Efficiency Resource Optimizer)
Introduction of H.E.R.O Tunnel kiln
GRM Group of companies introduced Red brick production machines to produce International stranded Red brick used for building construction, H.E.R.O automatic Tunnel kiln and Red brick production machine group is designed on German technology, and we fully reform the design of the equipment with most up to date international 3 dimension design software (pro ENGINEER), and the design of the automatic production line is in accordance with the national design criteria of the People’s Republic of China. In a tunnel kiln, which is a horizontal moving ware kiln, bricks to be fired are passed on cars through a long horizontal tunnel. The firing zone remains stationary near the centre of the tunnel, while the bricks and air move in counter-current paths. Cold air is drawn from the car exit end of the kiln, cooling the fired bricks. The combustion oils travel towards the car entrance, transferring part of their heat to the incoming green bricks. The cars can be pushed either continuously or intermittently at fixed time intervals. The tunnel kilns have provisions for air extraction and supply at several points along the length of the kiln.
