The Laboratory Jaw Crusher Pulverisette 1 is recommended for intermittent or continuous pre-crushing of coarse materials.
The maximum feed size is approximately 60 mm (model I) or 95 mm (model II). The maximum throughput is
140 kg/h (model I) or 200 kg/h (model II). The optimum fineness depends on the gap width adjustment for setting the distance between the crushing jaws – and therefore setting the final fineness, which is approximately
d50 = 15 mm (maximum gap width) d50 = 1 mm (minimum gap width)
The funnel of the FRITSCH Jaw Crusher PULVERISETTE 1 classic line is particularly accessible, quickly and easily filled even with larger sample quantities and easy to clean.Its design enables the crushed material to be automatically conveyed into the crushing chamber – blockages are practically impossible.
The crushing jaws can be removed for cleaning quickly and easily with just 2 hand motions.
Especially safe and dust-free: the enclosed grinding chamber prevents users from reaching inside and ensures a safe and dust-free operation of all moving parts. An integrated connection makes it very simple to combine the instrument with a dust exhaust system for automatic removal of the fine dust arising during grinding. The dust exhaust system is also very useful when cleaning the grinding parts.
The crushing jaws and lateral support walls of the Jaw Crusher Pulverisette 1 classic line are available in 6 different materials in order to avoid undesired contamination due to material abrasion. The standard version is equipped with fixed and movable crushing jaws as well as lateral support walls made of tempered steel.
Normally, crushing jaws and support walls of the same material are used. Since the lateral support walls are subject to low stresses, however, the standard lateral support walls made of tempered steel can often be retained.
For completely iron-free pre-crushing of medium-hard brittle samples, for example in the ceramics industry, we can equip your Jaw Crusher Pulverisette 1 classic line with crushing jaws made of zirconium oxide, lateral support walls in zirconium oxide or aluminium, and with a special PVC funnel. So you will have absolute protection against iron contamination, such as for dental ceramics.
Applications: mining and metallurgy, chemistry, geology and mineralogy, glass industry, ceramics, rocks and soils.
