كربونات الكالسيوم

Calcium carbonate (CaCO3), which occurs primarily in the form of the minerals calcite and aragonite, is one of the most prevalent compounds on Earth. Calcium carbonate is not only the main component of marble, limestone and dolomite, it is also found in bones and teeth as well as the exoskeleton of crustaceans, coral, muscles, snails and protozoa. A further modification of CaCO3 is the mineral vaterite, which precipitates out of supersaturated solutions in the form of microscopic crystals. 
There are many varied uses for calcium carbonate:

  • As raw material for the construction material industry (manufacture of cement and quick lime or limestone for building and road construction)
  • As aggregate in the steel industry
  • As abrasive and polishing agent in toothpaste
  • As mineral fertilizer
  • And as mineral filler or pigment in diverse industrial applications (paper, paint, plaster, plastic, carpet)

In addition to kaolin and talc, calcium carbonate is used in the paper industry as a filler and coating pigment in the production of paper. Since calcium carbonate is rhombohedral even when very finely ground, it is primarily used in papers with the highest degree of whiteness and good printability. Examples of these are coated printing papers or highly filled copy and office papers.

® NETZSCH Alpha® - الجيل القادم من مطاحن الخرز الرجراجة

NETZSCH-Feinmahltechnik GmbH has now developed the new Alpha® modular machine platform. Compared to earlier-generation machines, this series is designed such that different grinding systems can be mounted on the same base platform as appropriate for a defined drive capacity.

طاحونة القرص الأفقية نوع LME / LMK

The disk grinding system sets new benchmarks regarding capacity and flexibility. You profit from well-engineered technology that has already been proved for processing different products.

طاحونة القرص الرأسية نوع KE

The optimized, vertical disk grinding system guarantees reliable continuous operation at highest operating safety when processing mineral and ceramic products as well as cocoa masses.

طاحونة الخرز الخلاطة المخبرية LabStar

The multi-functional laboratory mill LabStar enables scientific academic work even at difficult research and development tasks and convinces by easy handling. The laboratory mill LabStar is the smallest grinding unit of NETZSCH-Feinmahltechnik GmbH that enables an exact scale-up to comparable production machines.

طاحونة مصنفة CSM 50 and CSM 80

طاحونة الصدم الميكانيكية بتكنولوجيا تصنيف متقدمة للغاية – مصمتة، متينة وبحد أعلى دقيق لحجم الجسيم. تصلح لدرجات نعومة من 10 إلى 150 ميكرومتر (d97) تتوفر الآلة بقياس سعة هواء طاحن من حوالي 100-180 Nm³/h.

مطحنة البخار® s- Jet

The s-Jet® System (patent pending) is a new innovation in a line of consistent developments being made in the area of air jet milling. Final finenesses in the submicron range (example: d50 0.2 µm) can now be achieved with fluidized bed jet mills. As opposed to conventional dry grinding processes with fluidized bed jet mills, the s-Jet® System uses superheated steam as its milling gas.

جهاز تصنيف نقاوة عالي الكفاءة CFS/HD-S

The requirements of many product applications such as improved separation sharpness and finer cut points, are no problem for the CFS/HD-S range of High-efficiency Fine Classifiers.

Thanks to the maximum predispersion of the product to be classified, the targeted cut point and sharpness of cut can be optimized distinctly.

Available for finenesses from 2.5 to 60 µm (d97).

Machine sizes available for gas volume from approximately 50 to 16.000 Nm³/h.

مصنف نقاوة CFS 5 und CFS 8

Efficient separation of grain sizes and effective results for both coarse material and fine material separation.

For separation limits from 10 to 250 µm (d97).

Machine sizes with gas volume of approximately 25 to 145 Nm³/h.

ماكينات تصنيف نقاوة ذات كفاءة عالية CFS 5 HD-S , CFS 8 HD-S

The smallest for the finest – exact separation results for superfine powder through best possible product classification with the sharpest separation and maximum gains.

For separation limits from 2.5 to 60 µm (d97).

Machine sizes with gas volume of approximately 25 to 145 Nm³/h.
