High-quality sand making and dry-mixed mortar integrated production line

Abstract

The invention relates to a high-quality sand making and dry-mixed mortar integrated production line. The production line comprises a sand making building and a dry-mixed mortar station; a raw materialaggregate bin is connected with a graded sand making machine and a grain shape optimizing machine, raw material aggregate enters a vibrating screen through a semi-finished product bucket elevator after being crushed by the graded sand making machine and the grain shape optimizing machine, the aggregate enters a first sand finished product bucket elevator after the stone powder content of the aggregate is controlled by a winnowing device, and part of the aggregate returns to the graded sand making machine and the grain shape optimizing machine to be treated; fine sand in a stone powder separator returns to finished product machine-made sand, the treated stone powder enters a stone powder storage bin, and the stone powder storage bin sends the stone powder into a stone powder bin; fine sandtreated by the stone powder separator is fed into a dry sand storage bin through the first sand finished product bucket elevator, and then is fed into a dry sand temporary storage bin through a second sand finished product bucket elevator; and all the materials are stirred by a stirrer, enter a dry-mixed mortar finished product bin and are stored through a dry-mixed mortar finished product bucketelevator. The production line has the following advantages: the integrated design is adopted, the occupied area is small, and the process arrangement is compact and reasonable.

Description

technical field

[0001] The invention relates to an integrated production line for high-quality sand making and dry powder mortar. Background technique

[0002] The river sand used in construction projects is increasingly in short supply or exhaustion in our country, and the promotion of machine-made sand has become the general trend. Dry powder mortar refers to a granular or powdery mixture of aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and admixtures that have been dried and screened in a certain proportion. Or transported to the construction site in bulk, the material can be used directly after mixing with water. The high-quality sand making line produces high-quality machine-made sand that meets the requirements such as fineness modulus and gradation, and then transports the high-quality machine-made sand to the dry powder mortar station. The high-quality machine-made sand that meets the requirements is then classified by a probabi...
