Testing an Automatic Concrete Block Making Machine With Your Own Concrete
A buyer's guide to demonstrating an automatic concrete block making machine using the buyer's actual concrete mix, with practical checks for cycle time, mold output, and acceptance testing.
Ask the supplier to run the demonstration with your own concrete mix, not a reference blend. Your aggregate grading, moisture, and cement content affect filling, compaction, and stripping, so a machine that performs well on the supplier's mix may behave differently on yours. Confirm the mix design and moisture range you will supply in advance, and request that the trial use that material.
During the trial, record the molding cycle against the reference range of 15–25 s and note whether it holds with your mix. Check the example mold output of 6 blocks per cycle at 390 × 190 × 190 mm as a reference value only, and ask what output your chosen mold and mix can realistically achieve. Verify pallet compatibility with the 850 × 680 mm pallet size and confirm the total motor power of 33 kW suits your site supply.
For acceptance, agree measurable criteria: block dimensions, green strength handling, surface finish, and cycle consistency across repeated runs. Ask how the machine responds if your mix moisture drifts.
Before requesting a quote, confirm with the supplier which mold sizes and pallet dimensions are included, the concrete mix parameters the trial will use, how cycle time and output are measured, and what acceptance tests and documentation accompany delivery.
