Clay conditioners can bring several benefits to your production process, but how can you measure effectively its effects on your specific process? We have asked this question to our R&D experts in the ceramic lab and this is what they have answered.
Registration, Evaluation, Authorisation & restriction of CHemicals (REACH) is a regulation that aims to make the handling and commercialisation of chemicals safer. In this blog article we talk about how this regulation affects heavy clay manufacturing in particular.
Once you have decided that using a clay additive will be the best solution for your production problem, you have to decide what quantity is the best for your specific production process.
Blake Stacey, technical consultant in Real Material Solutions (https://real-mat-sol.com) who has worked for many years in the ceramics sector, has written a testimony about solving production problems and finding the best way to work with the difficult clays on Western Australia. Here we share some of his thoughts:
Structural bricks provide greater insulation, more protection from the elements, and the appeal and durability that have always made clay brick a desirable building material. The manufacturing of large structural clay brick presents challenges to brick makers in two of the critical processes involved in brick making, extrusion and drying. In this blog we will focus on the drying part of the process.
Last week Munich hosted one of the largest ceramic exhibitions: Ceramitec 2018. From 10-13 April the international ceramics industry gathered around the exhibition, which was, in general terms, really successful. In case you couldn't attend, we were there to be able to show you.
When it comes to the use of ceramic additives, we must be 100% sure that the one that we are using is the best for their production process. We have talked about different ways to optimize ceramic production processes in several blog articles and we even wrote a blog post on the benefits of using additives in a brick production. However, we have received many questions about how additives can affect a manufacturing process. We will try to answer all of the questions as well as we can. This month's question is: "will the additive block my extruder if there's a production break?"
New aesthetics aligned with new technical requirements in the extrusion of ceramic bodies are demanding a new approach when it comes to additives’ requirements. In the past, lubrication and proper rheology were highly appreciated, but today there are other properties that should be taken into consideration if defects such as cracks, laminations, scumming, etc. can’t appear along the process, mainly due to the higher technical requirements of the raw materials.
Cracking – in whatever stage of production – is a major loss issue faced within all types of clay manufacturing and the reduction/elimination is paramount for increased profitability and yields.
Large Structural Brick
Brick types vary from thin brick to face brick to structural through the wall units. Thin brick allow for less weight and less costly installation. Face brick provide some insulation and are practically maintenance free for the lifetime of a building. Structural clay brick provide greater insulation, more protection from the elements, and the appeal and durability that have always made clay brick a desirable building material. The manufacturing of large structural clay brick presents challenges to brick makers in two of the critical processes involved in brick making: extrusion and drying. In this blog post we will focus on how to avoid breakage in the extrusion part of the manufacturing process.
