Title:
STONE CLASSIFICATION AND CRUSHING PROCESS
Document Type and Number:
WIPO Patent Application WO/2022/120896
Kind Code:
A1
Abstract:
The present invention relates to a stone classification and crushing process, in which the following process flow is used: a stone bin -> a mud and stone separator -> primary crushing in a crusher -> conveyor No. 1 -> secondary crushing in the crusher -> conveyor No. 2 -> tertiary crushing in the crusher -> a sieving machine. Block stones and a mixture of fine stones and mud are obtained by means of separation performed by the mud and stone separator; the block stones are subjected to the primary crushing in the crusher, the secondary crushing in the crusher, and the tertiary crushing in the crusher, so as to complete the course of stone treatment; and the mixture of fine stones and mud has mud filtered out therefrom by means of a cleaning pool, and is then conveyed to undergo the secondary crushing in the crusher and the tertiary crushing in the crusher, so as to complete the course of stone treatment. The rotation speed of the mud and stone separator is 45 r/min, and the pore diameter of a screen sieve is 50 mm. In the stone classification and crushing process of the present invention, a mud and stone separation procedure is added to an existing technological process flow, so as to treat organic matter such as mud prior to crushing, thereby omitting two subsequent cleaning operations, greatly saving on energy, and improving operation efficiency.
