ADVANTAGES

SIMULTANEOUS CRUSHING AND REDUCTION

The combination of JC 6M jaw crusher and Rotary sample divider into a single technological complex eliminates the stage of sample overload, which reduces dusting and increases productivity.

CRUSHING EFFICIENCY

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

Maximum initial material grain size is 50mm. Compact 1.1 kW electric motor.

The use of a shear pin in the mechanism for adjusting the gap between the jaws protects the crusher mechanism from breaking if an unbreakable body enters.

ACCURACY OF REDUCTION

Constant speed of the divider nozzle rotation ensures accurate reduction.

OPERATIONAL SAFETY

The rotating elements of the divider are covered by casing. The end switches exclude start-up of the crusher / divider without a loading hopper / with the cover open. The Jaw crusher has an emergency stop button for quick shutdown.

ADJUSTABLE DEGREE OF REDUCTION

Tray with a movable partition provides a smooth adjustment of the degree of reduction from 10% to 1% of the total sample volume.

RECEIVING BIN

The trays are designed to collect a reduced sample and the rest of the sample is collected in the receiving bin. Placing the receiving bin on the trolley provides the convenience of unloading sample residues.

SET OF TRAYS

Rotary sample divider is equipped with trays of different sizes:

  • 25% of the sample;
  • 10% of the sample;
  • 5% of the sample;
  • a tray with a partition that provides smooth adjustment of the degree of reduction from 10% to 1% of the total sample volume.

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 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 frame, a plate, a gear motor, a rotating nozzle, trays and a receiving bin. The gear motor transmits rotation to the nozzle through which the sample enters the trays. The trays are designed to collect a reduced sample and the rest of the sample is collected in the receiving bin. Placing the receiving tank on the trolley provides the convenience of unloading sample residues.

OPERATING PRINCIPLE

The sample is comminuted in the Jaw crusher, and then passes through the discharge funnel to the rotating nozzle of the divider. The product is unloaded into the installed trays and the receiving tank. After the crushing and reduction processes are completed, the cover of the divider can be opened and the trays with reduced sample can be removed.

Since the speed of the nozzle rotation is constant, the sample is dividing between the trays and receiving bin in proportion to their size. One or several trays can be installed in the sampler depending on the technological task being solved.
