Screening system of mortar drying line

Abstract

The invention discloses a screening system of a mortar drying line. The screening system comprises a sand silo, a multi-stage screening device and a crusher, wherein a discharge outlet of the sand silo is connected with a feed inlet of the multi-stage screening device, a distribution hole of the multi-stage screening device is connected with a feed inlet of the crusher, the crusher is further connected with the sand silo, and a discharge outlet of the multi-stage screening device is connected with a storage silo. Through the mode, the multi-stage circulating screening and crushing can be performed through the screening system of the mortar drying line, the particle sizes of raw materials are guaranteed, and the waste of raw materials can be reduced.

Description

technical field [0001] The invention relates to the field of mortar, in particular to a screening system for a mortar drying line. Background technique [0002] Because the general raw materials usually contain more large-sized stones, they cannot be used in dry-mixed mortar, resulting in a large amount of waste, resulting in waste; in commonly used sand, fine sand accounts for about 50%, and in the commonly used dry-mixed mortar formula, about 65% is used Fine sand, and plastering mortar and most special mortars only use fine sand. During the long-term production of the dry-mixed mortar mixing plant, due to the less use of medium sand and coarse sand, it is easy to cause the sand bin storing medium sand and coarse sand to explode. After the explosion, the materials in the storage bin need to be released through overflow, which is easy to cause material accumulation , The accumulated materials need to be re-transported when they need to be used, which is easy to generate a...
