ADVANTAGES

CRUSHING EFFICIENCY

The «tooth- trough» jaws combination provides high crushing performance. Crushing grains of material from 110 to 1 mm in one pass (90%). Equipping with a 5.5 kW electric motor, as well as a flywheel and a pulley of increased weight, allows crushing materials up to 7 Mohs hardness.

EASY MAINTENANCE

Lubrication of moving parts through grease fittings. Easy adjustment of V-belt drive by rotating slide plate. Quick-release lining armor.

OPERATIONAL SAFETY

The end switch excludes start-up without a loading hopper. Emergency «Stop Button» for quick shutdown. All rotating parts and assemblies are covered by casings.

COLLECTING CONTAINER

Possibility of completing with a collecting container of 15 liters on a roller trolley.

REINFORCED HOUSING

Collapsible housing design eliminates welding breaks. The front and side walls are made of 40 and 20 mm metal sheets with respectively. For assembling the housing M 20x45 bolts are used, which provide reliable walls fastening.

CONVENIENT ADJUSTMENT

Sawtooth threads (instead of metric) reduce the danger of jamming of the adjusting unit. A thread pitch of 3 mm allows to quickly change the gap between the jaws. The lock nut provides a reliable fixation of the gap.

EASY LOADING

Loading hopper configuration eliminates material ejection. An opening for connecting a dust extraction system is made in the rear of the hopper.

QUALITY SPARE PARTS

The moving and fixed jaws of JC 15 are interchangeable, and can also be rotated 180 °. Lining armor made of wear-resistant steel. Bearings manufactured by the Swedish company SKF.

COMPATIBILITY WITH ROTARY SAMPLE DIVIDER

Simultaneous crushing and reduction due to the combination of JC 15 Jaw Crusher and RSD Rotary sample divider in a single technological complex. Aggregation eliminates the stage of sample overload, which reduces dusting and increases work productivity.

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.

DESCRIPTION OF THE DEVICE

JC 15 is a jaw crusher with a complex movement of the jaw, the destruction of the material in which occurs due to compression and shear deformations. The size of the crushed material is determined by the gap between the jaws in the lower part (discharge gap) and the physical characteristics of the crushed material.

The structure of the crusher includes: the loading hopper, the housing with the base mounted in, the connecting rod and the slot adjustment device. In the lower part of the housing there is a receiving container, in the back — the electric motor with a belt tensioner.

Two jaws are located inside the housing: fixed one on the base and movable one on the connecting rod.

The base is suspended on the axis, and its position in the lower part is determined by the adjusting device. The screw of the adjusting device rests against the base through the unit with Belleville springs, which protect the crusher from breaking if an invincible body enters. In the adjusting unit, a sawtooth thread of increased diameter S 36x3 is used, which reduces the danger of jamming of the device.

Torque from the electric motor is transmitted through a belt drive to an eccentric shaft, on which a connecting rod with a movable jaw is mounted.

The loading hopper has a configuration that eliminates material ejection from the crushing chamber. The hopper loading opening is closed by the lid. The hopper is mounted on the housing through a rotary axis and is fixed by two latches. The hopper is equipped with two gas lifts.

In the lower part of the housing there is a nozzle for connecting the crusher to the dust collection system.

The inner surface of the walls in the crushing zone is protected by lining armor made of wear-resistant steel.

On the right side of the casing there is a bracket with the emergency stop button and the end switch that prevents the crusher from starting without a loading hopper.

OPERATING PRINCIPLE

Material is fed into the loading hopper, from where it enters the working space between the jaws. The upper smooth surface of the jaws is not involved in crushing. Middle surface is ribbed, which allows to increase the specific pressure on the particles of crushed material in the zone of preliminary crushing. The lower smooth lower surfaces of the jaws form a parallel zone — a zone of fine grinding, in which the product of the required particle size is obtained.

The complex movement of the jaw (primary horizontal vibrations in the upper part of the crushing zone and vertical vibrations in the lower part) provides a high degree of crushing.
