Building construction machinery and equipment — Concrete mixers —

Part 1: Commercial specifications

1 Scope

This document establishes the content for commercial literature for concrete mixers used either as individual machines on building sites or as components of batching plants. Definitions refer to whole machines, their structure and parameters. The commercial specifications establish technical characteristics of the whole machines and their components. Truck mixers, as defined in ISO 19711‑1, are excluded from this document.

2 Normative references

There are no normative references in this document.

3 Terms and definitions

For the purposes of this document, the following terms and definitions apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

3.1

concrete mixer

machine designed for the production of concrete by mixing of measured (by mass or volume) proportions of water, cement, aggregate and possibly chemical additives, within a certain time limit

Note 1 to entry: A concrete mixer can be furnished with the following accessories: charging skip hoist, fixed or wheeled, or self‑propelled supporting frame, mechanical shovel, water dosing equipment, and a skip weighing system.

3.1.1

batch-type concrete mixer

concrete mixer ( 3.1) in which charging with concrete constituents and discharging of the drum are carried out periodically, in batches

3.1.2

continuous-type concrete mixer

concrete mixer ( 3.1) in which charging with concrete constituents and discharging of the drum are carried out continuously as an uninterrupted flow

Note 1 to entry: See Figures A.15 and A.16 for examples.

ISO 18650-1:2021

3.1.3

gravity concrete mixer

free-fall concrete mixer

concrete mixer ( 3.1) where mixing is performed by repeatedly elevating the mixed concrete and dropping it from a certain height, inside a mixing drum, during its rotation

3.1.3.1

reversing-drum concrete mixer

reversing concrete mixer

gravity concrete mixer (3.1.3) with a reversible direction of rotation of the mixing drum where discharge of mixed concrete is by reversing the rotation of the drum

Note 1 to entry: See Figures A.4 and A.5 for examples.

3.1.3.2

tipping-drum concrete mixer

free-fall concrete mixer (3.1.3) with a tipping mixing drum, open at one end for charging and discharging of the concrete mix where discharging is carried out by tilting the drum

Note 1 to entry: See Figures A.1, A.2 and A.3 for examples.

3.1.3.3

discharging-chute concrete mixer

free-fall concrete mixer ( 3.1.3) with a mixing drum open at both sides where charging is carried out from one side and discharging from the other by means of a chute entering the drum

Note 1 to entry: See Figure A.17 for an example.

3.1.3.4

self-loading mobile concrete mixer

gravity concrete mixer ( 3.1.3) with a reversible direction of rotation of the mixing drum where discharge of mixed concrete is by reversing the rotation of the drum, integrated into a self‑propelled frame equipped with a self‑loading attachment intended to use for a complete production and batching of concrete, including transportation on road and off‑road to reach the pouring site

Note 1 to entry: See Figures A.23 and A.24 for examples.

3.1.4

compulsory concrete mixer

concrete mixer (3.1) with mixing effected by the action of one or more agitators moving inside a mixing chamber with either a vertical axis (pan) or horizontal axis (trough)

Note 1 to entry: See Figure A.18 for an example.

3.1.4.1

pan-type concrete mixer

compulsory concrete mixer ( 3.1.4) with agitators rotating about the vertical axis of a stationary or rotating pan

3.1.4.2

turbo concrete mixer

compulsory concrete mixer (3.1.4) with an agitator rotating about the vertical axis of a stationary pan, charged from the top and discharged by opening a segment of the pan bottom

Note 1 to entry: See Figures A.6, A.7 and A.8 for examples.
