A-3 pro

The A-3 pro high-performance vibrating sieve shaker enables the rapid determination of the quantitative particle size distribution of solids and suspensions in the measuring range from 20 µm to 63 mm. As a throwing sieve shaker with electromagnetic drive, it sets the sieve tower in controlled vertical oscillating movements and is suitable for sieving material quantities of up to 2 kg for dry sieving and up to 100 g for wet sieving.

Automatic amplitude control for exact reproducibility

The top model A-3 pro offers automatic amplitude control (AMPCONTROL) for guaranteed constant amplitude and exactly reproducible sieving results in accordance with DIN 66165-1. The device can be used as calibratable and validatable test equipment in test equipment monitoring in accordance with ISO 9001 and is therefore ideal for fast quality control in incoming and outgoing goods. It is particularly easy to operate via an ergonomic soft-touch pad with digital display of all functions.

Intelligent program selection and control

The microprocessor control allows up to ten individual screening programs to be stored. All functions can be controlled via the RS232 interface - in combination with the AUTOSIEVE software, the sieving process can be monitored via online comparison of the target and actual amplitude. Interval operation shortens the screening time for voluminous material with low density. An energy-saving mode automatically switches the device to standby.

Versatile screening options

The vibrating sieve shaker works with woven test sieves in diameters of 100 mm, 200 mm or 8". Up to ten test sieves can be used simultaneously per work cycle, so that up to five sieves can be used in parallel. The distortion-free EASYTWIST sieve tower tensioning system is included in the scope of delivery. The electric, easy-to-operate TorqueMaster sieve tensioning system, which ensures automatic and reproducible tensioning of the sieve tower, is available as an option.

An intelligent wet screening head with two rotating nozzles is available for wet screening. The optimum power consumption prevents the screening system from heating up and ensures quiet, robust and durable operation. The compact tabletop device with dimensions of 37 x 40 x 20 cm and a weight of 21 kg is designed for worldwide use with 100-240 V/1~, 50-60 Hz.

AUTOSIEVE software for automatic evaluation

The multilingual AUTOSIEVE software controls the A-3 pro and enables automatic evaluation, simple monitoring and documentation of the sieving results. After connecting a laboratory analytical balance, differential weighing is performed automatically before and after sieving. The software saves sieve weights of individual sieves and complete sieve sets and allows convenient input of all parameters such as amplitude, sieving time and interval operation via the computer.

From sieving to grinding in one device

The sieve shaker can be converted into a vibrating micro mill P-0 in just a few simple steps - for grinding and homogenizing small sample quantities with a filling quantity of 1 to 10 ml and a feed particle size < 5 mm. Grinding at low temperatures in liquid nitrogen is also possible with the special FRITSCH Cryo-Box. This modular system offers a wide range of possible applications.
