Qualitätssicherung Mahlwerk Letschert

Quality Assurance

To guarantee the excellent quality of our products we analyse the distribution of the grain sizes and measure the iron values of every grinding charge.

The monitoring of the grain size is carried out with a EML machine. The substance of magnetic elements is analysed with a laboratory vibration chute and an integrated magnetic separator.

Environmental protection is an important topic for us. In addition to our technical precautions to control dust formation and oil separation in production and logistics our final product contributes to our environment.

Our grinded chamottes consist to 85 % of recycled materials.

Our Story

Ernst Letschert KG was founded in 1936. In the early years, the company focus lied on providing transport and logistics however, soon developed to be a major player in the raw material industry. Today, the products of Letschert grinding plants play a significant role in the ceramic industry in Germany.

In the late 50s, Ernst Letschert started to grind flat glass for the ceramic industry in the production plant Ransbach-Baumbach. With the economic development of the ceramic industry the demand for grinded chamottes increased. To satisfy the demand for grinded chamotte stones he installed a ball mill: one of the first steps in the development of the raw materials company.

The construction of the grinding plant located in the industrial area of Ransbach called “Im Rohr” was a milestone in the company’s history in 1976. Manfred Zinndorf was leading this significant step for the firm. In the years from 1971 to 2005 he was director of the family business.

From 1992 on he was actively supported by Junior Director Christian Zinndorf who became authorised officer in 1996. After the loss of Manfred Zinndorf he then became Director of Ernst Letschert KG. Today, the grinding plant “Im Rohr” is the firms centre for production. Step by step, the areal of 15.500 square meters was extended to a highly flexible preparation plant including three separate grinding lines.
