A Drying Plant Designed Around Your Material: Dolomite, Calcite and Silica

In dry-mix mortar and construction chemicals production, drying is the first step that decides product quality. Damp sand clumps in the bag, does not blend evenly with cement and throws the recipe off, which is why we design each dryer around the material it will handle rather than a standard template.

Every unit is built as a finned or honeycomb type, taking into account the kind of product to be dried, its grain size and the level to which its water content has to be brought down. Dimensions, burner capacity and insulation are only fixed once the material analysis is complete, and the advanced design provides proportional combustion so that drying is done in the most economical way.

The target moisture also depends on the end product: a ceramic tile adhesive and a screed mortar do not tolerate the same moisture. Grain size directly affects drying time as well; fine material dries quickly, while coarse grains need longer to release the moisture they hold.

Which materials can be dried?

The plant is designed for dolomite, calcite, silica, quartz, volcanic minerals, pozzolan and similar industrial products.

Equipment

• Drive pinion and girth gear, both hardened by heat treatment
• Tyre rings that have also been heat treated
• Temperature regulated via a thermocouple
• Insulating jacket made of rock wool

Drawing on more than 50 years of manufacturing experience, we can work out the right dryer capacity for your plant from a sample of your material.
