roof-tiles

Roof-tile manufacturing involves several stages. Clay material is separated based on specific factors to fit the final product. Then, the material is rolled, and a mixture of fiberglass and cement, called fiber cement, is added in the mixing tank. Fiber cement is durable, water-resistant, and does not crack or rot.

In some cases, customers have installed the SDM WT in the underflow of the mixing tank to measure the % of solids and control the fiber cement’s thickness. The measuring instrument’s output is used to regulate the process using valves for water addition and slurry mass.

Due to frequent temperature changes, a PT-100 is necessary for real-time temperature compensation to accurately measure the % of solids. Controlling the % of solids ensures the correct product quality before the slurry is transported to the molding phase where roof-tiles are produced.

Measuring the % of solids in the feed to the machine is crucial because the mass of solids directly affects the roof tiles’ thickness. The end product requires a specific roof tile thickness. Failure to monitor and control the process can cause variations in density and affect the final product’s outcome.
