Then these crushed samples will be divided by the sample divider, and the final sample will be collected into the collection bottle and the redundant coal will back to the coal ...
the sample is collected into the sample hopper and the rest is dropped back to the truck. After the hopper is full, the sampler returns back to the home position to discharge the sample into the chute of the processing line for further sample processing. From the chute the sample is transported to the crusher to be sized down to 10mm.
For a compact crusher, our JC1250 can handle a high workload up to 5 kg samples comfortably. It has impressive throughput up to 140 kg/hr. With a heavy duty kW electric motor, JC1250 equals that of our JC2501, but with half the crushing chamber width, providing extra torque and power.

The heavyduty, general purpose Essa JC3000 Jaw Crusher is a well proven, highly productive primary crusher used in sample preparation and plant applications. More powerful than the JC2000, it is suitable for higher workloads and can handle large core and lump crushing.
Jeffrey's involvement with coal. For instance, when coal was shot down from the face, the pieces were often too big to fit into fireplaces and furnaces, so Jeffrey got into the crusher business, and before long it was selling more crushers for wood pulp, sugar cane, limestone, and eventually municipal waste, than for coal.
Dependable, heavyduty crushing options for low feed rates is a market niche covered by the McLanahan line of sample crushing products. From Jaw Crushers, to Hammermills, to Double Roll Crushers, an option likely exists within the McLanahan product offering that will meet your low tonnage, high dependability requirements.
Our Flagship Brands. In 2012, three legendary brands Gundlach Crushers, Jeffrey Rader and Pennsylvania Crusher were brought together to form. TerraSource Global. The Gundlach brand has long been known as an innovation leader in size reduction solutions, having helped redefine and expand the potential of crushing equipment.
TerraSource Global's Jeffrey Rader sample crushers are ideal equipment for moderatevolume sampling applications. These smaller hammermills keep the same high capacity range as our larger mills and are a cost effective solution for facilities with space constraints. We manufacture multiple sizes and configurations of our sample crushers.

Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.
