ADVANTAGES

CRUSHING EFFICIENCY

The «tooth- trough» jaws combination provides high crushing performance.

SIMULTANEOUS CRUSHING AND REDUCTION

The combination of JC 10 jaw crusher and Rotary sample divider into a single technological complex eliminates the stage of sample overload, which reduces dusting and increases productivity.

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.

ADJUSTABLE TRAY FOR ROTARY SAMPLE DIVIDER

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

Rotary 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.

Rotary 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 Jaw crusher when the Rotary sample divider is off.

DESCRIPTION OF THE DEVICE

The aggregate consists of three parts: Jaw crusher, Rotary sample divider and support frame with a funnel. The crusher is mounted on the support frame installed on the top of the divider. Crushed material flows from the crusher to the divider through the discharge funnel.

The aggregate consists of two parts: Jaw crusher and Rotary sample divider. The crusher is mounted on the top plate of the divider. Crushed material flows from the crusher to the divider through the discharge funnel.

The structure of the Rotary 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 is comminuted in the Jaw crusher, and then passes through the discharge funnel 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.
