Grading

Material Grading to Specific Requirements

Different applications require different material sizes. Rawmat provides custom material grading from 0–50 mm, allowing processed material to be prepared according to individual client requirements.

Our grading process forms part of the controlled processing cycle, combining crushing and screening to achieve the required material size. By tailoring production to client specifications, we can provide material that is prepared for its intended application rather than relying on a single standard output.

Our Grading Capability

• Custom grading from 0–50 mm
• Client-specific size requirements
• Controlled screening and separation
• Consistent material sizing
• Integration with crushing and re-crushing
• Production tailored to specifications

Whether material requires a particular size range or further processing to correct an oversize fraction, our team can incorporate grading into the overall processing requirement.

Sorting

Manual and Mechanical Material Sorting

Effective sorting is an important part of maintaining control over the material entering and moving through the processing cycle.

Rawmat provides manual and mechanical sorting services to separate and prepare raw materials for further processing. This allows material to be assessed and handled appropriately before continuing through crushing, screening, grading or other processing stages.

Our team combines practical experience with the appropriate sorting methods to support consistent and efficient production.

Our Sorting Capability

• Hand-sorting of raw materials
• Manual material separation
• Mechanical sorting techniques
• Preparation of material for processing
• Identification and separation of unsuitable or differing material
• Sorting according to processing requirements

Sorting can be incorporated into a wider processing project or used as part of a reworking requirement where existing material needs to be refined or prepared for further processing.

 Reworking

Refining Material to Meet Requirements

Not all incoming material is immediately ready for its intended use. Material may require additional sorting, screening, grading or crushing before it reaches the required specification.

Rawmat’s material reworking service provides an additional stage of processing for material that requires further refinement.

This can include correcting oversize material, re-crushing material, refining raw feedstock and adjusting the output through additional screening and grading.

Our objective is to bring material closer to the required specification while maintaining consistency and reliability throughout the process.

Our Reworking Capability

• Oversize material re-crushing
• Additional screening
• Material grading
• Hand and mechanical sorting
• Refinement of raw feedstock
• Processing according to client specifications

Our team works across the processing cycle to determine where additional work is required, helping ensure the final output aligns with the client’s requirements.

Material Recovery

Turning Suitable Waste Into Reusable Resources

Material recovery is an important part of Rawmat’s processing operation.

We work with suitable refractory and other raw materials that can be processed and returned to productive use. Through controlled crushing, screening, grading and sorting, material that would otherwise be considered waste can be transformed into reusable resources.

Our approach is focused not simply on recovering material, but on processing it to a consistent size and quality suitable for its intended reuse.

Our Recovery Capability

• Recovery of suitable refractory materials
• Processing of recovered material
• Crushing and screening
• Sorting and grading
• Transformation of waste into reusable resources
• Focus on consistent size and quality

By combining material recovery with our established processing capabilities, Rawmat helps maximise the usable value of suitable materials while maintaining controlled processing standards.

Materials

Refractory Materials We Process

Mag Carbon Grog

These materials and specifications are taken directly from the company profile.

Packaging

Ready for Handling, Transport and Reuse

Once material has been processed, screened and graded, Rawmat provides 1-ton bulk-bag packaging for finished material.

Bulk-bag packaging provides a practical method of handling processed material and prepares it for transportation, storage and eventual reuse.

Packaging forms the final stage of the processing cycle, allowing processed material to move from the production environment into a practical format for clients.

Our Packaging Capability

• 1-ton bulk-bag packaging
• Packaging of processed materials
• Practical material handling
• Transportation-ready packaging
• Prepared for reuse

This packaging capability is specifically identified in the company profile as part of Rawmat’s processing operation.

Processing Built Around Your Requirements

Every material presents its own processing requirements. Rawmat therefore focuses on understanding the required output and applying the appropriate combination of crushing, screening, grading, sorting, reworking and recovery to achieve it.

With four closed-circuit crushing plants, a skilled plant workforce and a commitment to consistent quality, we provide processing solutions designed around the requirements of our clients.
