How to overcome challenging extrusions

By Rosa Mediavilla 27-Jul-2020 07:30:00

Extrusion is a common process used to manufacture different types of ceramic products, for example, face bricks, ventilated walls, floor tiles, special shaped products and many others. Several parameters affect the operation of the extrusion. These parameters include the nature of the raw materials, their particle size, and their plastic behavior, the water content and the additives you use.

Using clay conditioners to optimize the drying of large structural bricks

By Bill Daidone 26-Apr-2018 12:01:00

 Structural Bricks

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.

How to optimize brick production through faster drying

By Jonathan Savage 07-Sep-2017 07:31:00

Before bricks and tiles can be fired the majority of water used in its moulding needs to be removed from the clay product. Any excess residual water or moisture left in the article as it enters the kiln to be fired will be removed very quickly leading to major problems such as blow out, warpage or in the extreme – as has been seen on numerous occasions – to explode causing serious damage to the kiln and production.
