Essa® Dry Bulk Rotary Samplers

Our range of Dry Bulk Rotary Samplers are low-maintenance sampling solutions for your operations. Our samplers are made with high-grade steel to ensure long wear life and come with easily replaceable cutters and inspection doors that ensure ready access for cleaning and maintenance.

Our range of Essa Vezin Samplers are designed to produce a truly proportional cross stream sample for primary, secondary or tertiary applications. A rotating sample cutter, located inside a fully enclosed unit, passes at constant uniform speed through the falling stream of sample entering from above.

Our Vezin range operates in accordance with recognised international sampling protocols using correct cutter geometry design with radial cutter edges, which accurately cut a fixed portion of the stream. The cutter is direct driven by a fixed-speed, three-phase electric motor and gearbox combination. Up to four cutters can be fitted to ensure the required amount of representative sample is collected. The replaceable cutter lips are manufactured from Ni-Hard steel.

• The Essa Vezin Sampler is specifically designed to be a minimum maintenance unit.
• The cutter and liners are readily replaceable in the field.
• Radial (wedge-shaped) cutter opening cross section as is required for rotary style samplers.
• Convenient access/inspection panels.
• Optional internal rubber lining.
• Optional automatic internal washdown.
• Proximity switches to ensure cutter parking is out of the stream.

Our Essa Dry Arcual Sampler is a fully enclosed unit containing a traversing radial sample cutter that passes at uniform speed through the falling stream of ore. These samplers are designed for cross-stream sampling of free-flowing granular material in a vertical pipe installation .

As with the Vezin sampler, the design and operation of the DAS is designed in accordance with recognised international sampling protocols, using correct cutter geometry design with radial cutter edges that accurately cut a fixed portion of the stream. The cutter is direct driven by a fixed-speed, three-phase electric motor and gearbox combination, with a cutter spoon designed to ensure that the required amount of representative sample is collected.

The sampler is constructed from wear-resistant steel with replaceable cutter lips, manufactured from Ni-Hard steel fitted to the cutter spoon.

• Flanged connection to process pipe/chute work.
• Inspection door and top openings for cutter adjustment and cleaning.
• Easily replaced cutter blades.
• Electric drive for constant speed control.
• Proximity switches to ensure cutter parking is out of the stream.

We’ve designed our Essa Rotary Tube Samplers to ensure a precise amount of sample material is delivered to each chute discharge. This is achieved by splitting the sample material between in-feed hoppers and the material discharge chutes at the base of the machine body.

The sampler includes a braked gear motor with a belt drive, contained within a head unit that rotates a material chute. Separate discharge chutes are fitted under the body of the head unit to divide the material. These discharge chutes are available in configurations ranging from two chutes to multiple chutes in a number of combinations to give the desired split percentages. Several differing percentage combinations of chute can be fitted at the same time.

• Two hinged inspection doors with mesh screens behind.
• Belt-driven rotating head via a braked gear motor.
• Replaceable cutter blades enclosed in the outfeed discharge chute assembly.
• Options for different in-feed chute sizes and multiple out-feed chutes of various percentages for split of the sampled material.
• Reliable, accurate and precise sample collection and division.
• Radial (wedge-shaped) cutter-opening cross-section as is required for rotary style samplers.
• Easily replaceable cutter lip assemblies.
• Convenient access/inspection panels.
• Proximity switches to ensure cutter parking is out of the stream.
