The dry mix mortar production line is a fully automatic complete set of building material production equipment integrating raw material storage, automatic batching, precise weighing, closed mixing, finished product storage, automatic packaging, dust purification and intelligent electric control. Adopting modular design, it is divided into simple mobile type, semi-tower type and full-automatic tower type, with a production capacity of 1–100t/h, and the layout can be customized according to factory size and production categories. The whole line adopts fully sealed negative pressure dust removal design with standard dust emission and high automation. Only 1-2 operators are required for full-process production, completely replacing traditional on-site manual mixing. It effectively solves the industry pain points such as uneven mortar proportioning, unstable quality and serious on-site pollution, and is widely suitable for large-scale production of various ordinary and special dry mortars.
