Novel dry-method artificial sand manufacturing device and manufacturing process thereof

Abstract

The invention discloses a novel dry method artificial sand manufacturing device and a manufacturing process thereof.The device comprises a first smashing box, a driving box and a second smashing box, a crushing mechanism and a screening mechanism are arranged in the first smashing box, and a transmission mechanism for driving the crushing mechanism to swing is arranged in the driving box; the transmission mechanism controls the crushing mechanism to swing on the upper side of the screening mechanism to hit stones on the screening mechanism; and the second crushing box communicates with the first crushing box so that stone particles can fall into the second crushing box, and a crushing mechanism and a soaking mechanism are arranged in the second crushing box. The stone particles are soaked when the stone particles are crushed, so that the water content of the stone particles is increased, the sand forming rate of the crushing roller can be increased, the amount of stone powder generated in the stone sand making process can be effectively controlled, and meanwhile, compared with a wet sand making process, more water resources are saved.

Description

technical field [0001] The invention specifically relates to the technical field of sand making, in particular to a novel dry-process artificial sand manufacturing device and a manufacturing process thereof. Background technique [0002] Common sand making processes include wet sand making, dry sand making, and semi-dry sand making processes. The wet sand making process usually uses clean water to wash the sand making stones to remove the soil entrained in the stones to reduce the soil content in the artificial sand, and then put the stones into the sand making machine for crushing, and the produced sand passes through the metal grid Screening, sand materials whose size meets the requirements of artificial sand are rinsed with water and stored in the sand field, and those whose size is too large will enter the sand making machine again to make sand again, so that the reciprocating cycle completes the production of finished sand. [0003] For the sand making process in the p...

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of dry artificial sand manufacturing device and its manufacturing process, to solve the sand making process in the prior art proposed in the above background technology, the wet artificial sand production process uses a large amount of water to wash, the production process Although there is no dust pollution in the process, a large amount of water resources are consumed in the production process, and the content of stone powder produced by the dry sand making process is too high, and the moisture content of the sand making raw materials entering the sand making machine in the semi-dry sand making process is relatively low. The problem of low sand making rate of sand making machine
