Since 1956, TCKI has built up a wealth of knowledge and experience relating to ceramic production processes. Many companies have been able to improve their processes based on our advice.
The processes for raw material preparation, shaping, drying and firing must all for their own function well. The production and product quality must also fit together optimally.
Clients can trust our professionals in the laboratory, the measuring group, the drawing office and the consultancy group. Together they support companies with measurement and advice in optimizing and renewing their production processes.
Of course we can also apply the knowledge gained to other production processes with similar characteristics.
Mixing clay with sand or other additives has the aim to obtain a homogeneous mixture. TCKI advises companies in the ceramic industry and other industries when it comes to handling of clay, sand and other bulk materials in raw material preparation installations.
There are various machines on the market, with different characteristics, for the mixing of clay, sand and other additives. We can assist you in selecting the machine that best suits your specific situation, based on:
Based on the composition of the raw materials, we advise which machines are the most suitable as far as production efficiency and energy use are concerned. TCKI uses a specific measuring method to quantify the mixing action of various types of raw material preparation machines.
The shaping behaviour of clay can be characterised based on different laboratory analyses on a raw material. Due to our many years of experience, we can indicate for each raw material composition which shaping method is most suitable for achieving the desired production quantity and quality.
For most cases we can advise on how the shaping behaviour can be influenced or improved.
TCKI has expertise in the field of damage-free drying of many types of products. Our vast expertise in the field of drying processes can also be applied to other sectors.
The damage-free and energy efficient drying of wet shaped clay products can only be performed properly if the drying process is completely controlled. Based on our laboratory research, we can characterise the clays and give a first estimate of the required approach.
Measuring and recording
We use a laboratory climate chamber to conduct drying tests on single products in order to search the drying limits. We use a pilot dryer to conduct production tests on site. We use this to determine the correct lay-out, equipment and processes in an industrial dryer, or we establish that modifications in the current situation are required. We can measure and record the atmospheric conditions and physical parameters of the products in dryers that are used in practice in order to optimize the drying process, step by step.
Ceramic products get their characteristics by a firing process, at which, under certain atmospheric conditions, the products are exposed to high temperatures to sinter.
One of the key competencies of TCKI is knowledge about firing clay-like raw materials to ceramic products. This knowledge is based on years of experience in analysing raw materials, firing trials in a laboratory gas-fired kiln, atmospheric measurements, measurements of firing curves, energy and mass balances and the quality evaluation of the fired units.
This forms the basis of the advice to companies about the design and improvement of kilns, adjustments of firing curves and atmospheres and the flue gas and air balance
The shaping of clay products requires various moulding or extrusion machines. We can draw up a lay-out of the machine set-up and a list of requirements for these machines.
We also supervise projects from initial idea formation right through to the delivery of drawings, calculations and advice. TCKI also uses measuring methods to evaluate and if necessary modify the operation of presses in the ceramic industry.
The ceramic industry regularly asks TCKI to assist in the design and selection of handling machines for the transport of
We also advise on the purchasing of
Based on the set of requirements, we can design a complete, new lay-out or we can integrate the new machines in the existing production line.
TCKI performs ISO 17025 accredited flue gas emission measurements, which are used by the authorities to award environmental permits. Our specialised measurement technicians use our van with measurement equipment to record emission concentrations in an accurate and reliable manner. These measurements include the concentrations of:
If the emissions for flue gas components exceed the limits, we can on behalf of the client draw up a list of requirements for flue gas cleaning, request and compare quotes, supervise the implementation of a new installation and provide acceptance measurements upon completion.
In the ceramic industry TCKI performs the engineering and the entire permit course for complete production plants. In consultation with the client, we can design, supervise the whole stretch and assist in realising the entire project. First we use laboratory tests to determine which clay preparation, moulding, drying process and firing processes are required to manufacture the product desired. We define the technical lay-out based on the raw materials composition and the product definition.
And we do much more:
TCKI is able to perform and to supervise all essential project activities in a centralised manner, in order to ensure a prompt completion of the project.
