CBM 25 Block Making Machine Installation – Mali

The first thing you notice in the photos from this installation is the rows of fresh blocks in front of the machine: hollow concrete blocks straight out of the mould stand in neat rows on the pallets, with the machine that pressed them right behind. For a customer in Mali, we installed and commissioned a CBM 25 block and paving stone machine in its standard version, without the pallet stacking robot. Our team ran the first production with the customer's operators and trained them in operating the machine, changing moulds and daily maintenance.

What the freshly moulded blocks tell you

A fresh block has to carry its own weight before it has hardened, so the first pallets are the best indicator of whether the mix and the machine settings are right. In the rows in the photo, the corners are full, the edges sharp, the cavity walls upright and the surfaces evenly textured, with no slumping, cracks or broken corners. That shows the moisture of the mix and the vibration and pressing settings of the CBM 25 were set correctly at commissioning.

A single outdoor line: from hopper to pallet

The plant was set up on open ground enclosed by a block wall, with the machine and equipment standing on a concrete base. This is the path the material takes along the line:

1. Belt conveyor: an inclined belt conveyor carries the prepared concrete mix up to the top of the machine.
2. Hopper: the mix collects in the large orange hopper above the machine and from there fills the mould.
3. Second hopper: the unit on the left of the press in the side view is the second hopper of the CBM series; for double-layer paving stones it supplies the concrete of the top (face) layer.
4. Press: the press, with İBAR MAKİNA lettering on its front frame, fills the mould under vibration and compacts it. The hydraulic hoses reach the machine through metal channels along the ground, and the control cabinet stands right beside the line.
5. Pallets: the blocks leave the mould on pallets in front of the machine; the side view shows pallets loaded with fresh blocks between the second hopper and the press, with an operator beside them.

Why a CBM 25 without a robot?

Another of our installations in Mali is a CBM 25 R line with a pallet stacking robot: the same press and the same moulds, plus a robot that stacks the fresh pallets on top of each other. Here the customer chose the standard CBM 25, in which the pallets leaving the mould are taken to the curing area with a pallet trolley. The investment is lower and the line simpler; where labour is easy to find, that is a sensible way to start production. Capacity is the same in both versions. For anyone thinking of a smaller start, our BLOCKMASTER 8 installation in the same country is a useful comparison.

Capacity by mould

According to our product record, the CBM 25 produces per cycle and per day:

• Block 100x400x200 mm: 18 pcs per cycle, about 18,000 pcs a day
• Block 150x400x200 mm: 12 pcs, about 12,000 pcs a day
• Block 200x400x200 mm: 10 pcs, about 10,000 pcs a day
• Curbstone 150x700x300 mm: 3 pcs, about 3,000 pcs a day

The machine has twin hoppers, so with a change of mould it can also make double-layer paving stones (25 per cycle, about 500 m² a day).
