Separating Drums for Safe Sorting

Often copied, never equalled. This MTF discovery sets the benchmark for separation drums. The planet-central adjustment in combination with the counter-running roller pairs is unique.

• Fast and easy adjustment of the separation gap without tools
• Counter-running rollers prevent jams and part damage
• Large throughput capacity
• Separation gap infinitely adjustable between 3 and 53 mm
• Available as standard in two diameters and four different lengths
• Rollers made from PVC, steel or stainless steel
• Steel rollers are foam-covered for noise reduction

Especially large separation drums with separation lengths of 1,000 or 1,200 mm, large drum diameters and steel rollers often require a reinforced base .

• Base infinitely adjustable in height and angle
• Available for all separation drum types and sizes
• Can be combined with soundproofing hoods, covers, etc.
• Available in additional special configurations, e.g. with steel lattices, container uptakes, additional supports, etc.
• Reinforced wheels with large diameter for uneven floors
• Further attachment options available for the die-casing industry - e.g. motor covers, steel cable sheathing as protection for the drive units, etc.

Especially in the die-casting industry or with the separation of harder materials in steel drums, an elevated noise level becomes an issue. In addition to sound dampening by the installation of foam-covered rollers, noise emission can also be significantly reduced with an additional sound-proofing hood.

• Folding cover with foam padding
• Outer hull of anodized aluminium, galvanised steel, stainless steel or acoustic panelling with foam filling
• Folding mechanism allows easy access for adjustment of the separation gaps
• Available for all MTF separation drums

The drum cages of MTF separating drums are driven by a friction wheel as standard. Thus serious injuries to machine operators by the spinning cage are already prevented. However, sharp-edged pieces that come through the separation gaps can pose a safety hazard.

For these cases, MTF Technik offers safety coverings in a variety of configurations.

• Covers from perforated metal or polycarbonate allow a visual control of the separation process
• Lightweight, removable covers made from polycarbonate are available as dust and intrusion protection
• Available for all MTF separation drums

Separable goods with the same height but different surface areas can be perfectly separated in a perforated drum. The design of the hole shape, size and distribution as well as the choice of materials for the drum cage, etc., always depend on the task-specific basis of the pieces to be separated.

• Drum cages made of steel, stainless steel, rubber, silicone, etc.
• High throughput capacity
• Hole cages can easily be changed
• Separating lengths between 500 and 1200 mm standard

Special needs require special solutions. Surface-sensitive and hot pieces can, for example, be separated in a silicone drum.
This version - also as a rubber drum - is also suitable for the pre-deburring of Duroplast pieces. The fine Duroplast skins, which often cling to the pieces after the removal from the forms, can be perfectly pre-deburred in drums with reversible turning direction in combination with special sloughing media.

• MTF develops countless special solutions in the area of separation technology depending on the problem at hand
• Our extensive facility in the pilot plant allows tests with your sample pieces

Whenever pieces can "wander" through the separation gaps of roller separation drums or perforated drums, hedgehog drums offer a solution. The sleeve pipes welded to the outside of the hole cage reliably provide an interlock-free and secure separation result.

• Drum cages normally made of stainless steel
• Separation lengths of 500 to 1200mm standard for the series
• Hole geometry and distribution are designed specifically for the task on the basis of sample pieces
• Often used in clean rooms

If multiple different pieces are produced in the manufacturing process, the separation process must accordingly have multiple steps. This can be achieved by repeated separations - e.g., in one central-adjustment separation drum with multiple settings - or in multi-stage separation drums.

• Combination of different hole and sleeve geometries depending on the task
• Individually designed length and composition of the individual separation zones
• Fall-out shafts separated zone-wise under the drum cage
• Container pick-ups can be integrated in the base
• Different lengths, diameters and materials available

For separation tasks in the clean room or in medical technology, the prevention of wear as well as the protection of the pieces plays a special role. Here MTF Technik offers a multitude of separation devices that already optimally fulfil your task in many clean room applications.

• Form rings can be provided with special coverings in stainless steel functionality
• Available in a variety of diameters, lengths and types
• Simple disassembly and cleaning possible

Pieces that are still connected to the sprue after removal from the form from the tool must next be sloughed before the actual separation process can begin. MTF Technik installs sloughing drums for this purpose. This uses a sloughing medium (e.g., hardwood, plastic, steel rollers, etc.) that is placed free in the drum cage and is carried around with the parts and sprues. The variable turning direction of the drum cage ensures that the sloughing medium constantly falls against the pieces and breaks the connection to the sprue.

• Projection based on sample parts
• Many sloughing media depending on the task
• High throughput capacity
• Drum operation usually as roller separation drum with separate adjustment or as perforated drum

After the patents for the separation drums with individual adjustment as well as the planet-central adjustment mechanism, MTF Technik envisions a further novelty with the patented rectangle drum. The rectangle drum uses separation vents opened by an innovative mechanism defined in the upper area of the drum.

• Defined opening separation gaps effectively prevent piece jams and damage
• Simple and quick adjustment of the separation gaps
• Especially suited, for example, to the separation of softer materials that can otherwise easily jam in separation gaps
