Description of equipment

Extremely powerful and compact FRITSCH jaw crusher PULVERISETTE 1 with a drive power of up to 3 kW, it delivers extremely high throughput and is the ideal instrument for fast and efficient primary crushing. Operation: the sample is crushed vigorously in the jaw crusher under high pressure between one fixed and one movable crushing jaw in a closed chamber. It allows for the grinding of hard or very hard, brittle materials up to the hardest iron alloys! The freely accessible crushing chamber and the smooth surfaces in the crushing chamber allow easy cleaning and prevent sample cross-contamination. A Plexiglas cover allows visual inspection of the crushing chamber and monitoring of the action. The slit, which determines the final granularity of the sample, can be determined externally with millimetre precision.

Technical data:

• 3 kW, which provides a higher grinding capacity;
• Input particle size is 95 mm, final size 0.3 - 15 mm;
• simple design for fast and efficient cleaning;
• the final grit size is adjustable in 1 mm increments;
• adjustable jaw movement to achieve a more uniform final grit size;
• the minimum quantity of sample to be crushed shall be 20 ml;
• Maximum capacity: 140 kg/h at the lowest grit size up to 250 kg/h at the highest grit size;
• the possibility of sequential or continuous sample addition;
• Tungsten carbide jaws for grinding extremely hard materials and for minimal sample contamination;
• easy cleaning to prevent cross-contamination of samples.

FRITSCH disc mill PULVERISETTE 13 is used for efficient fine grinding of hard and medium hard materials. It is ideal for crushing medium sized particles in mining and metallurgy, ceramics, rock and soil, glass, soil exploration. The filling can be batch or continuous. In a disc mill, the material is crushed under pressure and sheared between two opposing grinding discs. Due to the specially shaped teeth on the disc, the material is automatically fed through a pre-adjustable slot for the grain size of the output grinding and falls into a collection drawer. The desired final grit size can be set by simply digitally adjusting the width of the slot in 0.05 mm increments. Cleaning is made easy by the removable infeed hopper and the smooth surfaces of the grinding chamber, while the sealing of the grinding chamber provides further protection against contamination or sample loss. Grinding is dust-free thanks to the special exhaust system and the sealing of the drawer.

Technical data:

• electronically adjustable final grit size;
• Capacity 150 kg/h;
• suitable grain size up to 20 mm;
• final grain size up to 0.05 mm;
• Crushing principle: Strig;
• minimum sample quantity: 20-30 ml;
• the sample can be added in stages or continuously;
• tungsten carbide disc for grinding extremely hard materials and for minimal sample contamination;
• easy cleaning to prevent cross-contamination of samples.

The connection system between the PULVERISETTE 1 and the PULVERISETTE 13 consists of a custom-built feeder carrier that links the two machines into a single, compact and powerful shredding system:

• allows continuous pre-grinding and final grinding in one column;
• compact design that combines both instruments into a single system;
• suitable for small batch shredding;
• vhodna zrnavost <95 mm, izhodna zrnavost>0.05 mm.
