Production system and production method of machine-made gravels

TLDR: In this paper, a production system consisting of a feed hopper, a feeding machine, an early crushing system, and a medium crushing system is described, where the feed hoppers are used for delivering an aggregate into the feeding machine; the early-crushing system is used for early crushing the aggregate; the medium-crumpling system was used for crushing the aggregates again; a gravel-making machine for further crushing aggregate was arranged behind the mediumcrumbling system; and a first screen was used behind the gravel making machine and was used to outputting the aggregate meeting

Abstract: The invention relates to a production system and a production method of machine-made gravels. The production system comprises a feed hopper, a feeding machine, an early crushing system and a medium crushing system, wherein the feed hopper is used for delivering an aggregate into the feeding machine; the early crushing system is used for early crushing the aggregate; the medium crushing system is used for crushing the aggregate again; a gravel making machine for further crushing the aggregate is arranged behind the medium crushing system; a first screen is arranged behind the gravel making machine and is used for outputting the aggregate meeting a first particle size section; the aggregate not meeting the first particle size section is shaped by a gradation adjustment system and then returned to the gravel making machine; and all modules are connected with one another by virtue of an aggregate conveying system. By adopting the production system and the production method of the machine-made gravels, the output of the machine-made gravels meeting a required fineness modulus can be improved by controlling reasonable gradation, and the quality of the machine-made gravels is improved by reducing the content of flat and elongated particles by the gravel making machine.
