ACCURACY OF REDUCTION

VF 1 Vibratory feeder provides an adjustable supply of material from the hopper through the discharge nozzle. Since the rotation speed of the trays of the divider is constant, the sample is dividing between the trays proportionally to their volume.

OPERATIONAL SAFETY

The rotating elements of the divider are covered by casing. The end switch excludes start-up of the divider with the cover open. In the open position, the cover is securely fixed.

NO SAMPLE CONTAMINATION

The loading hopper, tray and discharge nozzle of the feeder, as well as the adjustable tray of the divider are made of stainless steel AISI 321.

ADJUSTABLE DEGREE OF REDUCTION

Tray with a movable partition provides a smooth adjustment of the degree of reduction from ⅛ to 1/80 of the total sample volume.

SET OF TRAYS

Rotating sample divider is equipped with trays of different sizes:

• 3 trays for 1/4 of the sample;
• 1 tray for 1/8 of the sample;
• a tray with a partition that provides smooth adjustment of the degree of reduction from 1/8 to 1/80 of the total sample volume.

Rotating sample divider can be equipped with trays of other sizes upon special order.

NO LOSS OF SAMPLE MATERIAL

Tight installation of the trays, as well as the sealing between them, excludes the spilling of the sample past the trays.

COMPATIBLE WITH CONTROL PANEL

The control panel is designed to start and stop the equipment and provides:

• automatic power off when exceeding the maximum current value or short circuit;
• protection of the operator from electric shock;
• motor overload protection.

The control panel eliminates the start of the Vibratory feeder when the Sample divider is off.

The aggregate consists of three parts: VF 1 Vibratory feeder, Rotating sample divider and support frame. The feeder is mounted on the support frame installed on the top of the divider. Material flows from the feeder to the divider through the flexible hose.

The structure of the Rotating sample divider includes a receiving bin, trays, a gear motor and a shaft. The gear motor transmits rotation to the receiving bin, in which five removable trays are mounted. Three trays have the same volume — ¼ of the original sample. Two trays have a volume of ⅛ of the original sample, while one of them has a movable partition providing a reduction of the sample from ⅛ to 1/80. The adjustable tray is made of stainless steel. The trays are connected with sealing, which increases the representativeness of the reduced sample.

OPERATING PRINCIPLE

The sample loaded into the hopper is evenly fed from the vibrating tray through the flexible hose into the trays of the divider. Since the rotation speed of the receiving bin is constant, the sample is dividing between the trays proportionally to their volume.
