Brick & Block Manufacturing Accessories
Supporting Reliable Production, Consistent Quality and Scalable Output Across Africa
At PJR Engineering, we know that a high-performing brick or concrete block plant is not defined by the main machine alone. Long-term production stability, product consistency and return on investment are achieved through correctly specified accessories that support every stage of the manufacturing process.
This accessories range is aimed at brick and block manufacturers, contractors, developers and industrial producers operating in South Africa and across Africa, who require dependable production support rather than catalogue-driven equipment sales.
Why Accessories Matter in a Concrete Block Plant
Inconsistent batching, worn moulds or poorly matched auxiliary equipment typically result in:
-
Variable block strength and surface finish
-
High reject rates and material wastage
-
Production bottlenecks and unplanned downtime
-
Increased labour dependence and rising operating costs
Well-specified accessories protect your capital investment, stabilise daily output and ensure that your block machine operates within its intended performance envelope.
PJR Engineering approaches accessories as part of a complete production system, not standalone add-ons.
Concrete Batching Equipment
Concrete batching equipment forms the foundation of consistent block and brick quality. Accurate proportioning of cement, aggregates and water is essential for achieving predictable compressive strength and dimensional stability.
Where it fits in the line
Batching equipment sits at the front of the production process, feeding measured material volumes into mixers and downstream block machines.
Problems it solves
- Inconsistent block strength caused by manual batching
-
Excess cement usage due to poor measurement control
-
Labour inefficiencies and slow cycle times
Key selection considerations
-
Required production volume per shift
-
Aggregate size and moisture variability
-
Level of automation required
-
Ease of maintenance and calibration
Best suited for
-
Start-up block plants transitioning from manual mixing
-
Established manufacturers seeking tighter quality control
PJR Engineering assists clients with batching equipment selection that aligns with both current output targets and future expansion plans.
Batching Station
A batching station provides a structured and repeatable approach to material handling, storage and weighing. It centralises batching control and improves overall plant workflow.
Where it fits in the line
The batching station acts as the operational hub between raw material storage and concrete mixing.
Problems it solves
Disorganised material flow and plant congestion
-
Inconsistent batching accuracy between shifts
-
Reduced production efficiency in high-output plants
Key selection considerations
Aggregate and cement storage capacity

Concrete Batching Equipment (Systems & Mixers)
The QT6-15 Block Machine is designed as a fixed, entry-level automatic block production solution for businesses moving beyond manual or semi-manual manufacturing. It offers a stable foundation for commercial block production while remaining practical and cost-effective for African operating environments.
Unlike the mobile configuration, this model is typically installed as a semi-permanent or permanent plant, making it suitable for operations that have secured a site and are planning consistent production.
Best suited for:
- New block yards establishing commercial-scale production
- Contractors producing blocks on-site for ongoing construction projects
- Developers stabilising block supply for housing or infrastructure programmes
- Businesses transitioning from manual production to automation
Key capabilities:
- Automatic hydraulic forming and vibration compaction, delivering consistent block density and repeatable quality
- Designed for continuous daily operation, supporting reliable output without excessive mechanical complexity
- Supports multiple product types, including hollow blocks, solid blocks, pavers and kerbs through interchangeable moulds
- Fixed plant configuration, providing improved stability and alignment compared to mobile systems
- Integrates into complete production lines, allowing connection to mixers, conveyors, stackers and curing systems as operations expand
Operational Context
The QT6-15 Block Machine is commonly selected as a first permanent plant. It allows manufacturers to establish predictable production, train operators on automated processes, and refine mix designs before scaling into higher-capacity systems.
Many operators use this model as a platform for growth, expanding output by upgrading supporting equipment rather than replacing the core machine prematurely.

Frequently Asked Questions
How do I choose the correct batching capacity for my plant?
Batching capacity should be aligned with your target daily output, block machine cycle time, number of shifts and mix design. Oversizing increases capital cost without benefit, while undersizing creates production bottlenecks.
PJR Engineering assists clients with capacity matching during the specification stage to ensure balanced production flow.
What is the difference between basic batching equipment and a batching station?
Basic batching equipment focuses on accurate material measurement, while a batching station provides a more structured system incorporating storage, weighing, feeding and control. Batching stations are typically used in higher-output or more automated plants where workflow efficiency and repeatability are critical.
Can accessories be integrated into an existing brick or block plant?
In many cases, yes. Accessories such as batching equipment, mixers, moulds and splitters can often be integrated into existing operations, subject to compatibility, layout and capacity assessment. A technical review is recommended to avoid mismatched output or inefficiencies.
How does mould quality affect block strength and consistency?
Mould quality directly impacts compaction efficiency, dimensional accuracy and surface finish. Poor-quality or worn moulds lead to inconsistent block sizes, higher reject rates and reduced strength. Correctly engineered steel moulds improve repeatability and extend service life.
Do accessories influence production downtime?
Yes. Incorrectly specified or poorly integrated accessories are a common cause of downtime. Issues such as batching delays, mixer wear or mould changeover inefficiencies can significantly reduce output. Selecting accessories as part of a complete system helps minimise these risks.
What information is required to receive an accurate quotation?
To provide a meaningful quotation, PJR Engineering typically requires the plant location (country), target daily output, product range (blocks, pavers, pipes), available footprint, power supply details and preferred automation level. This ensures that recommendations are technically appropriate.
Are spare parts available for accessories supplied?
Accessories supplied through PJR Engineering are supported with access to appropriate spares planning and maintenance guidance. This helps clients maintain uptime and avoid extended production interruptions over the life of the equipment.
Can accessories support future expansion or automation upgrades?
Many accessories are modular and can be scaled or adapted as production requirements grow. Early consideration of future expansion allows batching systems, mixers and structural components to be specified with long-term scalability in mind.
Is crushing and sand washing equipment necessary for all plants?
Not always. Its necessity depends on local aggregate quality. In regions where sand contains excessive fines or contaminants, crushing and washing equipment can significantly improve block strength and finish while reducing material variability.
Can accessories be integrated into an existing brick or block plant?
In many cases, yes. Accessories such as batching equipment, mixers, moulds and splitters can often be integrated into existing operations, subject to compatibility, layout and capacity assessment. A technical review is recommended to avoid mismatched output or inefficiencies.
