Description

The PMSA® VB4 brick, block and paver making machine is a top-class large-capacity machine. This powerful concrete brick, block and paver making machine is capable of producing 108 000 bricks, 64 800 pavers, 56 000 maxi bricks or 18 000 hollow blocks (140 mm width) per 9-hour shift on a 1 400 mm x 760 mm wood or composite production board. Depending on the level of automation, plant configuration and options, a plant can be operated with approximately 20 production and product handling staff with manual packing of products and approximately 8 production and product handling staff with a fully automated plant.

The VB4 is designed to consistently produce high-quality bricks, industrial strength pavers, hollow blocks, decking blocks, retaining wall blocks and garden kerbs. The PMSA® VB4 is reliable and Built to Last® owing to its robust heavy-duty channel frame.

Due to the high productivity, technology and life span of the VB4, it can produce industrial strength high-quality products with low production costs for decades.

Productivity

PMSA® customers have found the VB4 is capable of exceeding production capacities. The technology used in the VB4 allows for dependable output every day.

Due to PMSA®’s excellent market leading technical support and immediately available spare parts support, many PMSA® customers exceed the stated production capacities, resulting in improved productivity and increased profits.

Technology

Design features of the VB4 block machine include a heavy-duty channel frame designed not to fail or crack after decades of working under normal operational conditions. The VB4 is supplied standard with full PLC controlled operation, rubber bellows for mould box clamping, and tamper vibrators and VSD (Variable Speed Drive) direct driven twin-shaft oil bath vibrator (including forced air motor cooling). These technical design features of the VB4 result in lower cement consumption due to high compaction, excellent dimensional consistency of products and fast cycle times.

PMSA® provides technology training and workshops for our customers to assist them in continually improving production, quality and profitability.

Built to Last®

Buy once, buy right! Having a machine that lasts for decades means you don’t have to replace your VB4 every few years; it has been Built to Last®. PMSA®’s VB4 brick, block and paver making machine will continue to produce profits that can be reinvested into expanding your business instead of replacing inferior equipment. Our customer’s success stories prove the PMSA® Built to Last® philosophy, with many customers operating the VB4 range of machinery for more than 35 years – still in daily production. This results in PMSA® customers enjoying greater success.

PMSA®’s VB4 is Built to Last® and the ideal large size machine for a brick, block and paver making business. Features of the VB4 include:

Mechanical Features

  • Heavy-duty channel frame for long life and machine rigidity, which results in the production of quality concrete products consistently for decades.
  • 4 hard-chromed guide columns with easily replaceable wear-resistant guide bushes for accurate tamper and mould box movement to ensure dimensional consistency of products.

Vibration System Features

  • Direct driven twin-shaft oil bath vibrator-boxes with forced air motor cooling for vertical table vibration, providing consistent compaction over the full mould area, resulting in uniform product density, increased compaction of concrete products and reduced cement consumption.
  • Adjustable vibration frequency/speed control via VSD (Variable Speed Drive) provides optimum compaction for different product types being manufactured, reducing machine maintenance costs and increasing productivity.
  • Dynamic main vibration braking for reduced cycle times.
  • Electrical control panel includes timer-controlled pre-vibration for optimal mould filling.
  • Main vibration is controlled either over time for product density or upon reaching product height, or both.

Mould Filling and Feeder-box Features

  • Fixed concrete silo and adjustable feeder-box assembly is easily adjustable to accommodate different moulds.

Tamper and Mould Box Features

  • Optional tamper vibration for increased product density and smooth top surface.
  • Pneumatic mould clamping with rubber bellows for better vibration control.
  • Heavy-duty tamper brake assembly to lock tamper movement during mould lifting, preventing product damage.

Hydraulic Features

  • Powerful hydraulic system for fast and smooth mould, tamper, feeder-box and production board-feeder operation, giving faster cycle times, lower maintenance costs and extended component life.
  • Hydraulic power pack and machine controls are placed away from the machine for operator safety and unobstructed view of machine operation.

PLC and SCADA Features

  • Standard PLC controlled operation.
  • All machine parameters can be changed using a touch-screen interface while the machine is in operation for instant adaptation to changing moisture content and aggregate consistency, without stopping the machine.

  • High-performance powerful hydraulic system with accumulator, high response proportional hydraulic valves and encoders for closed loop PLC feedback and variable speed during the stroke of every hydraulic operation (for smooth, precise and fast movement of tamper, mould, feeder-box and production board feeder), resulting in faster cycle times,lower maintenance costs and extended component life
  • Hydraulic oil cooling and/or heating systems
  • Ceramic lining of feeder-box table
  • Mould-changing arm for faster mould change

Weigh batching and mixing options

  • Aggregate weighing and feeding
  • Automatic cement scale fed by inclined cement screw conveyor from cement silos or bag breaker and holding bin assembly
  • Water addition can be done by manual or automatic operation
  • Fully automatic weighing and batching option with PLC control of aggregates, cement, water, admixtures and mixing times is available
  • Moisture compensation in aggregates and moisture control in mixer
  • Increased mixer size is available (PMSA® P1500 counter current) when utilising moisture control

Production board, product handling and curing options (designed to suit customer needs)

  • Rail travelling stacking gantry to remove wet product on production boards from the chain conveyor and stack on either side of chain convey or used in conjunction with the PMSA® standard or premium packing range
