设计简介
摘 要:混凝土搅拌站主要由称量系统、输送系统、搅拌系统、贮存系统和控制系统组成，本次设计目标是设计出一种双缸双轴式搅拌机和一个相匹配的输送机。通过对生产率的要求来设计输送系统，再通过计算出来的相关数据确定搅拌系统的数据从而进行设计。通过查阅资料，在设计过程中有详细的计算设计，让搅拌站各个系统统一协调。
关键词:混凝土搅拌站；双缸双轴搅拌机；带式输送机
Abstract: Concrete mixing plant consists of weighing system, conveyor system, mixing system, storage system and a control system. The design is to be aimed at creating two-cylinder two axle mixer and matching belt conveyor. The conveyor system design is based on the requirement of productivity, and the mixing system is based on data which is calculated from relevant statistics got from the former steps. By consulting sources, the whole design derives from sophisticated calculation to make sure that systems in the mixing plant are working in coordination.
Key words: Concrete mixing plant; Double-horizontal-shaft concrete mixer; Belt conveyor
