Los molinos planetarios son ideales para la molienda ultrafina de materiales duros, semiduros, blandos, quebradizos, viscosos y húmedos. El material a moler se tritura en su mayoría mediante impacto de alta energía por medio de bolas de molienda en vasos de molienda rotativos.
La molienda se puede realizar en seco, en suspensión o bajo gas inerte. Además de para moler, los molinos planetarios se pueden emplear para mezclar y homogeneizar emulsiones y pastas o para aleaciones y activaciones mecánicas en la investigación de materiales.
Cross Beater Mill - cast iron grinding insert
The fast mill for all tasks
With a freely adjustable rotor speed of 2,000 – 4,000 rpm, the FRITSCH Cross Beater Mill PULVERISETTE 16 is the ideal universal mill for fast and gentle pre-crushing and fine-grinding of medium-hard, brittle materials up to a Mohs hardness of 6 in laboratories, pilot plants and industry.
Comminution can take place batchwise or continuously. The maximum feed size for bulk solids is up to 25 mm. For batchwise operation, a 5 litre collecting vessel with filter hose is delivered as standard. A 30 litre collecting vessel with filter hose is also available for larger quantities. The final fineness depends on the selection of the bottom sieve and the breaking properties of the respective material. A final fineness of < 100 μm can often be achieved after the first step due to the powerful drive and a rotor speed of up to 4,000 rpm.
The PULVERISETTE 16 offers highest operational safety: if the quick-clamping lock is opened unintentionally, a safety switch activates the motor brake so that the rotor comes to a stop.
Impact, friction, shearing
Comminution in the Cross Beater Mill takes place through impact, friction and shearing forces. The feeding funnel guides the grinding material directly into the centre of the grinding chamber, where it is comminuted between the cross beater and the teeth of the grinding insert. The selected bottom sieve determines the final fineness. The rotating cross beater also creates airflow through the funnel that accelerates the discharging of the ground sample into the collecting vessel. The supplied filter hose can be integrated here to effectively reduce the release of fine dust.
Configure your Cross Beater Mill PULVERISETTE 16 exactly to your specific application
The Cross Beater Mill PULVERISETTE 16 is equipped with a grinding insert and cross beater made of cast iron, and impact plates made of hardened steel. Also included is a stainless steel 5 litre collecting vessel with filter hose and a bayonet lock that ensures an especially convenient and dust-free connection. The bottom sieve must be ordered separately.
Bottom sieves made of stainless steel with trapezoidal and square perforation determine the final fineness of the sample. In general, the finer the desired final fineness, the smaller the perforation of the bottom sieve should be; the larger the perforation, the higher the throughput.
For batchwise operation, a 5 litre collecting vessel with filter hose is delivered as standard. A 30 litre collecting vessel with filter hose is also available for larger quantities. The PULVERISETTE 16 can be easily fixed to a table or the FRITSCH Universal support stand may be ordered.
The Cross Beater Mill PULVERISETTE 16 is also available with a grinding insert made of harder stainless steel
