Shaker carries an object to conduct linear or circular motion at different speeds, and then mix
the material.
Fig. 1 is the schematic diagram of Shaker SK-D3309-Pro. There are Speed display, Time
display, speed control knob, and timer knob on instrument control panel; power switch, on
the side of instrument; After properly connect the power cord and turn on power switch, users
set experimental conditions on the control panel by speed control knob and timer knob, and
real-time observe parameters setting values and actual values on screen.
Power supply: 220/110V → power outlets → PCB → system control power supply
Movement: motor drives Movement Module to rotate. According to a different lock screw
location on Rocker Plate, the movement pattern of shaker is different.
Speed feedback: the motor speed is accurately measured by the Shaft Encoder fixed on the
motor along with photoelectric switch and a feedback is given.
LCD display: LCD PCB is connected to Master Control Board and displays user’s settings
and current equipment operation information.
