本指南包括通过体积测量和连续搅拌（VMCM）生产混凝土的设备（通常称为移动式搅拌机）的基本设计和操作的简短历史和信息。讨论了定义、应用和质量保证测试。该设备的使用与称重分批混合设备进行了比较，以突出一些有限的差异。

This guide includes a short history of and information on the basic design and operation of equipment, frequently called mobile mixers, used to produce concrete by volumetric measurement and continuous mixing (VMCM). Definitions, applications, and quality assurance testing are discussed. The use of this equipment is compared with weigh-batch-mixing equipment to highlight some of the limited differences.
