Our products
The mining, processing of bentonites and the subsequent production of products based on them represent the core pillar of the production program of KERAMOST, a.s. The unique properties of this raw material provide the prerequisite for its versatile use.
The product created by processing bentonite raw material is increasingly popular with cat and other small animal owners. Natural and therefore ecological materials of all types and colors meet the demanding requirements of customers in the European Union
Metakaolin is ground, heat-treated floated kaolin. It is used as an additive in refractory materials, concretes and mortars, as a filler in rubber and plastics, and for other applications.
An extrusive igneous rock used as a flux for ceramic materials and some glass stocks. The use of Phonolite reduces the melting temperature and shortens the firing time. The resulting energy savings are primarily reflected in lower operating costs.
KERAMOST, a.s. produces and supplies crushed aggregate - basalt for use in all areas of the construction industry. Various fractions are available according to customer requirements.
Floated kaolin is a raw material sought after especially by the paper industry for its exceptionally high whiteness and low abrasion. Metakaolin is applied as an additive to concrete, mortars and plasters, rubber and plastics, where it improves their prop

This video presentation summarizes the basic process procedures for the production of bentonite bedding. However, the introductory part is also the same for the extraction and processing of bentonites for further use in industrial applications such as construction, foundry, etc. We always pay attention to the economical use of all natural resources so that they remain preserved for future generations. The production process has a number of inter-operational controls, where parameters such as humidity, dustiness or granulometry are monitored. Before the actual shipment, the given production batch must be approved by the output laboratory control according to the customer's specifications. The final products always have guaranteed safety, quality and homogeneity of deliveries.
