Want to know about the mixing process of a Prima concrete block machine?

First of all, it should be said that vibro-compressed concrete elements are produced in practically every country in the world due to the high quality and demand of this economical material in housing construction. A wide variety of raw materials can be used to produce vibro-compressed concrete units in different sizes and shapes.

However, it should also be pointed out that despite all the details that must be taken into account, the process of producing concrete blocks in a factory with Poyatos equipment is quite simple and includes the following process:

1. Dosing Unit

The aggregates that make up the concrete must be evenly distributed throughout the mix which is of primary importance to avoid the appearance of lumps.

2. Hoppers for sand and gravel storage

Secondly, the aggregates are stored in hoppers built by the client in concrete or metal prefabricated units. The aggregates are separated by type and size depending on the required mixing process.

3. Volume-based dosage belt conveyors

Once the second step has taken place, these belts transport the material from each hopper via a horizontal collecting belt, or skip, and from there to the mixer.

4. Aggregate elevator belt or Skip

The purpose of this belt is to elevate the measured aggregates to the mixer. These are custom designed for each project.

5. Cement Silos

The use of bulk cement is recommended. A silo is required for correct storage.

6. Mixer support frame

This is a metal or concrete structure that is used to support the mixer.

7. Mixer

The quality of the final product from the concrete block making machine begins with the drum capacity; therefore it is important to pay special attention to the mix design and mixing capacity

8. Water dosage timer

This is an automatic device which controls the quantity of water (pre-established for correct humidity levels) which the system requires in order to work automatically in optimum conditions.

9. Control desk

The entire process of dosage and mixing is managed by an automatic system that controls the input of aggregates, cement dosage and the degree of humidity required by the process.

10. Installation and safety according to EC regulations

Includes proximity sensors for mixer cover safety, protection rails on conveyor belts, permanent protective railings surrounding work areas and automatic shut-down.

11. Wooden trays

The pieces are manufactured on wooden trays which can be supplied in accordance with the regulations of the block machine model.

12. Curing chamber

This is the area where cement is worked using a semi-dry, semi-wet mixture.

13. Molds

There is a mold for each type of product which is supplied on request.

14. Other optional steps in the mixing system process of Basic Prima concrete block machines

Remote assistance via MODEM, computerized control system for visualization on touch screens and process management via PC. Double layer concrete device for paving stones and curbstones. Planetary countercurrent concrete mixers. Microwave water dispenser. Automatic cleaning systems for mixers…
