Планетарная мельница
PULVERISETTE 5/2
classic lineПожалуйста, обратите внимание: Для планетарной мельницы PULVERISETTE 5/2 classic line Вам понадобится еще как минимум 2 размольных стакана на ваш выбор и соответствующее количество размольных шаров. К тому же материал размольного стакана должен быть тверже, чем измельчаемый материал. Обычно используются размольные стаканы и шары из одного и того же материала. Для сокращения времени измельчения размольные стаканы и шары высокой плотности и таким образом с большей ударной энергией. Пожалуйста, учитывайте полезный объем, он не идентичен с объемом стакана!
Материал | Основной компонент материала | Плотность г/см³ | Износостойкость | Применение для измельчаемого материала |

Спеченный корунд | Al2O3(99,7 %) | 3,8 | условно хорошо | пробы средней твердости, волокнистые пробы |
Нитрид кремния | Si3N4 | 3,25 | экстремально хорошо | абразивные пробы, измельчение без металла |
Оксид циркония | ZrO2 | 5,7 | очень хорошо | волокнистые, абразивные пробы |

Размольные шары с диаметром 3 мм и меньше нужно взвешивать. Приведенная выше таблица содержит указания по необходимой навеске на размольный стакан.
Количество размольных шаров может быть уменьшено на вплоть до 15 %, однако тогда нужно считаться с повышенным износом. Указанное наполнение шарами на стакан является минимальным количеством; в зависимости от поведения материала, его, возможно, следует увеличить.
Обычно используются размольные стаканы и шары из одного и того же материала. Для сокращения времени измельчения размольные стаканы и шары высокой плотности и таким образом с большей ударной энергией.
Выберите не менее 2-х размольных стаканов в соответствии с вашим объемом проб, предлагаемых в размерах 500 мл, 250 мл и 80 мл. Подробности по полезному объему указаны в руководстве по выбору. Размольный стакан 80 мл: В одном креплении стакана можно зажимать друг над другом 2 размольных стакана на 80 мл или 1 размольный стакан на 80 мл вместе с адаптером.
Для достижения наилучших результатов измельчения все размольные стаканы предлагаются в исполнении из 7 различных материалов. Это позволяет целенаправленно избегать загрязнения проб нежелательной стружкой

Система измерения давления газа и температуры GTM для непрерывного измерения давления газа и температуры непосредственно в размольном стакане превращает планетарные мельницы PULVERISETTE 4, PULVERISETTE 5 и PULVERISETTE 6 серии FRITSCH classic line в аналитическую систему.
Для быстрого и надежного применения в атмосфере защитного газа и для механического активирования и легирования рекомендуется применять газовые крышки classic line.
Также можно получить сертификат IQ/OQ.
This Gas Pressure and Temperature Measuring System developed in cooperation with the Fraunhofer Institute for Applied Material Research (IFAM) in Dresden, is for use with the Planetary Mills PULVERISETTE 4, PULVERISETTE 5, PULVERISETTE 6 of the FRITSCH classic line transform them into analytical measurement systems.
Through the continuous direct measurement of gas pressure and temperature, it is possible to monitor thermal effects as well as physical and chemical reactions or pressure variations within the grinding bowl. To achieve this, the grinding bowl is simply used with a radio transmitter located in the lid, without any modification to the mill itself. The monitored data is passed by a receiver to a computer running a special WINDOWSTM programme and allows for graphical presentation of the measurement values and collating them in an ExcelTM table.
Technical Data
• Data evaluation via PC
• Range of pressure build up to 15 m
• Operating time with fully charged battery approx. 80 h
• Adaptation of measurement rate to the signal dynamic for maximum possible battery life
• Sleep mode of the radio transmitter with consistent measurement signals
• System requirements: Standard WINDOWSTM-PC
• UHF radio transmitter, 10 mW, no approval or fees necessary
• Up to two transmitter components can be operated simultaneously in the mill
• Measurement rate single/ dual transmission operation of up to approx. 200 measurement value/s
• Pressure measurement range 0 to 800 kPa (8 bar)
• Temperature measurement range of the transmitter component 10 to 70 °C
• Resolution of pressure signal: < 0.024 kPa
• Resolution of temperature signal: 0.025 K
• Permissible transient (-2 s) heat of reaction 30 kJ
• Receiver component also functions as charging station for the batteries of transmitter component
• RS232 connection to PC
• 250 ml or 500 ml bowls made of stainless steel
Advantages of the GTM System
The GTM-System can be used wherever batch quantities are ground in a totally enclosed container. Special grinding bowls made of stainless steel in capacities 250 ml and 500 ml are available.
The GTM-System provides valuable information
• Investigations in the area of mechanical alloying for the production of new amorphous and nano-crystalline materials
• Monitoring and optimisation of grinding processes in industrial applications
Through measurement of the grinding bowl temperature, it is possible to make an integral statement on temperature as a process variable that takes account of the effects of all friction, impact and transformation processes. The continuous and highly sensitive measurement of the gas pressure in the grinding bowl allows the detection of very rapid reactions. The measured gas pressure describes, amongst other things, the interactions of the gas with the surfaces created during grinding (adsorption and desorption of gases).
Extremely rapid phase formations can for the first time be observed IN SITU as an adiabatic process without heat exchange from the system.
Adjustment of the grinding parameters rotational speed, balls/ sample material ratio and grinding time can be performed first time without expensive, time-consuming and abortive trials.
Due to precise measurement of reaction times, for example, new materials can be prepared through specific addition of reaction partners, or produced with special mechano-chemical properties.
Equipment: The gas pressure and temperature measuring system (GTM) consists of a 250 ml grinding bowl made of hardened, stainless steel with special lid, transmitter and separate receiver.
If further grinding bowls and transmitters are used, please ask for the respective order number!

This Gas Pressure and Temperature Measuring System developed in cooperation with the Fraunhofer Institute for Applied Material Research (IFAM) in Dresden, is for use with the Planetary Mills PULVERISETTE 4, PULVERISETTE 5, PULVERISETTE 6 of the FRITSCH classic line transform them into analytical measurement systems.
Through the continuous direct measurement of gas pressure and temperature, it is possible to monitor thermal effects as well as physical and chemical reactions or pressure variations within the grinding bowl. To achieve this, the grinding bowl is simply used with a radio transmitter located in the lid, without any modification to the mill itself. The monitored data is passed by a receiver to a computer running a special WINDOWSTM programme and allows for graphical presentation of the measurement values and collating them in an ExcelTM table.

Advantages of the GTM System
The GTM-System can be used wherever batch quantities are ground in a totally enclosed container. Special grinding bowls made of stainless steel in capacities 250 ml and 500 ml are available.
The GTM-System provides valuable information
• Investigations in the area of mechanical alloying for the production of new amorphous and nano-crystalline materials
• Monitoring and optimisation of grinding processes in industrial applications
Through measurement of the grinding bowl temperature, it is possible to make an integral statement on temperature as a process variable that takes account of the effects of all friction, impact and transformation processes. The continuous and highly sensitive measurement of the gas pressure in the grinding bowl allows the detection of very rapid reactions. The measured gas pressure describes, amongst other things, the interactions of the gas with the surfaces created during grinding (adsorption and desorption of gases).
Extremely rapid phase formations can for the first time be observed IN SITU as an adiabatic process without heat exchange from the system.
Adjustment of the grinding parameters rotational speed, balls/ sample material ratio and grinding time can be performed first time without expensive, time-consuming and abortive trials.
Due to precise measurement of reaction times, for example, new materials can be prepared through specific addition of reaction partners, or produced with special mechano-chemical properties.
Equipment: The gas pressure and temperature measuring system (GTM) consists of a 500 ml grinding bowl made of hardened, stainless steel with special lid, transmitter and separate receiver.
