Technical Breakdown
Jaw crusher (primary, hard rock)
First-stage reduction for quartzite, dolerite, granite, and other compressive-hard formations. Feed sizes to 800-1000mm; product typically 100-250mm as feed for secondary crushing.
Impact crusher (primary or secondary)
First-stage reduction for softer rock, sandstone, weathered material, and demolition rubble where reinforcement rules out a jaw. Product ranges from crushed base to graded aggregate.
Cone crusher (secondary and tertiary)
Fine-tuned aggregate production from primary feed. Delivers 0-6mm, 6-13mm, 13-19mm, and 19-26mm streams for civil, road, and concrete supply.
Vibrating screen (double / triple deck)
Classifies crushed material into stockpiled product streams. Double deck for two-product civil work; triple deck where three separate aggregate grades are required.
Mobile deployment
Track-mounted or wheel-mounted plant positioned on site and moved between work fronts as haulage requirements change. Reduces stockpile haulage compared to fixed-plant processing.
Feed rate matching
Loader and dump truck cycle times matched to crusher throughput. Under-feeding wastes crusher capacity; over-feeding creates congestion and stops the line.

Frequently Asked Questions
What crusher type is right for my material?
It depends on hardness and target product. Jaw crushers are the first choice for hard rock — quartzite, dolerite, granite — where the material resists compressive load. Impact crushers handle softer material better: sandstone, weathered rock, and demolition rubble where a jaw would jam on rebar. Cone crushers are the secondary or tertiary stage, producing graded aggregate from primary product. Where multiple product grades are needed, we run a two- or three-stage train with vibrating screens between stages. We confirm the right configuration against your material and product specification at quoting stage.
Can you produce graded aggregate to civil specification?
Yes. Typical output from a two-stage crushing and screening train is graded 0-6mm crusher sand, 6-13mm, 13-19mm, and 19-26mm base course. Screen deck configuration is matched to the grades you need. Sampling and gradation testing can be arranged during production to confirm compliance with SANS-graded specifications. For higher-spec concrete aggregate, we discuss the geological source at quoting stage — some material sources do not produce clean concrete-grade product regardless of the crushing configuration.
What throughput can mobile crushing plant achieve on site?
Throughput depends on material hardness, crusher configuration, and feed cycle management. A typical mobile crushing and screening train processes 100 to 300 tonnes per hour on medium-hardness rock in single-shift operation. Continuous-shift work requires maintenance windows built into the schedule. Feed rate is the bottleneck on most sites — the crusher runs at its throughput ceiling only if loaders and dump trucks are matched to cycle time. We confirm target throughput and haulage integration at quoting stage.
Do you handle demolition rubble processing on site?
Yes. Reinforced concrete demolition rubble is processed through impact crushing — not jaws, because reinforcement bar jams the moving faces of a jaw crusher. Steel reinforcement is separated post-crushing via magnetic separation where the volume justifies it. The end product is typically crushed base course, useful as fill on the same site or on adjacent projects. On-site rubble processing eliminates the transport cost of removing waste to landfill and the return cost of buying imported fill, which is a significant cost lever on redevelopment and industrial demolition projects.
