Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a homogenization feeding device for concrete mixing plants. Background Technology

[0002] Concrete batching plants are mainly used in concrete construction projects. Their main purpose is to mix and blend concrete. Batching plants can be divided into single-unit plants and double-unit plants. As the name suggests, a single-unit plant has one mixing host, a double-unit plant has two mixing hosts, and a multi-unit plant has more than two mixing hosts. Each mixing host corresponds to one discharge port.
