Dry-mixed mortar production method and production line

Abstract

The invention discloses a dry-mixed mortar production method and production line. The dry-mixed mortar production line comprises production equipment. The production equipment is provided with a sand silo used for storing sand and a powder silo used for storing powder. The production equipment further comprises a preparation device, and the preparation device comprises a crusher and a separating unit. An inlet of the separating unit is connected with an outlet of the crusher. A sand outlet of the separating device is connected with a sand conveying pipeline, and a powder outlet is connected with a powder conveying pipeline. According to the dry-mixed mortar production method and production line, the sand and powder required for preparation of dry-mixed mortar can be both obtained from broken materials after stone is broken, in other words, part of or all the sand and powder required for preparation of the dry-mixed mortar are separated from the broken materials after stone breaking, and it actually means that machine-made sand and machine-made powder are used for replacing part of natural sand and natural powder. Hence, dependence on the natural sand in dry-mixed mortar production process is reduced, production cost and energy consumption of the dry-mixed mortar are lowered, and production efficiency of the dry-mixed mortar is improved.

Description

technical field [0001] The invention relates to a dry powder mortar production method and production line. Background technique [0002] At present, the concrete used in traditional building construction is wet concrete, that is, after the user purchases it, it can be poured directly, and the concrete will harden to form strength after waiting for an hour or two. However, dry powder mortar is required in the construction of walls, ceilings and floors. Dry powder mortar is slightly different from our common wet concrete. After purchasing, users must add a certain amount of water and mix it well. Related construction can be carried out. In developed countries, the ratio of wet concrete and dry powder mortar is about three to two. Ready-mixed dry-mixed mortar has achieved remarkable results in improving the construction environment, reducing labor intensity, reducing material loss and reducing dust and noise pollution. Dry-mixed mortar is being rapidly popularized nationwide....

AI Technical Summary

Problems solved by technology

However, because the production line uses natural sand to dry and then adds powder and additives to mix into dry-mixed mortar, it is affected by factors such as sand mining cost, efficiency, and energy consumption of natural sand and powder, so the production line is preparing dry-mixed mortar. Mortar has the problems of low production capacity, high energy consumption, large investment, consumption of natural sand and environmental impact
