Automatic Block Production Line

A turnkey fully automatic concrete block production line integrating mixer, batching, forming, conveying, stacking and pallet return under one PLC system, making hollow blocks, solid bricks, porous blocks and pavers by mould change (up to ~2100 blocks/h). OCALWA supplied this type of line to Colombia.

Turn cement and aggregate into blocks and pavers

A concrete block machine mixes cement, sand, aggregate and water, then vibrates and presses the mix in a mould to form hollow blocks, solid bricks, porous blocks or paving stones. Changing the mould changes the product, so one machine makes a full range of masonry and paving units.

Machines range from compact semi-automatic units to large fully-automatic PLC lines with mixer, batching, conveyor, stacker and pallet return. OCALWA supplies single machines or complete turnkey block production lines from a verified factory, and has supplied a full automatic line to Colombia.

Configurations & options

Output, block/panel sizes, motor power and configuration are matched to your production target, raw material and site. Send us your target blocks or m3 per hour and product sizes and we specify the right machine or line.

Why choose these block machines

One machine, many products

Swap moulds to make hollow blocks, solid bricks, porous blocks and pavers on the same machine.

High density and strength

Forced vibration and hydraulic pressing make dense, strong units that meet construction standards.

Scale to your investment

Start with a compact machine or a full automatic line, and add capacity or a second line as demand grows.

Frequently asked questions

By changing the mould, one machine makes hollow blocks (e.g. 390x190x190mm), solid bricks, porous/perforated blocks and interlocking road pavers. We supply the moulds for the products you want.

Output depends on the model: from about 380 standard hollow blocks per hour on a compact machine up to 1,900-2,100 per hour on a large fully-automatic line, and thousands of solid bricks per hour. We size the machine to your target.

Yes. Hydraulic press models compact cement mixes as well as fly-ash, slag and other industrial-waste raw materials into high-density bricks with no firing, saving cost and using local materials.

A turnkey line includes the host block machine, a twin-shaft forced mixer, aggregate batching, belt conveyor, a brick separator/palletizer (stacker), automatic pallet-return feeder, PLC control, interchangeable moulds and pallets. This is the type of line OCALWA supplied to Colombia.

Lead time is typically a few weeks to a couple of months by machine size, FOB China. Main machine parts carry a 12-month warranty; moulds and wear parts are consumables. Exact terms come with each quote.

Yes. We provide foundation and layout drawings, and for lines we send engineers for on-site installation, commissioning and operator training, plus spare-parts supply and technical support.

Yes. We deliver single machines or complete turnkey lines (block production, batching or road-base plants): layout design, manufacture, shipping, on-site installation, commissioning and operator training, from a verified factory. OCALWA supplied a complete automatic block production line to Colombia.
