Method for improving qualified rate of limestone granularity
The invention discloses a method for improving a qualified rate of limestone granularity. The method comprises the following steps: 1) subjecting limestone to pretreatment, digging unnecessary topsoil and interlayer impure soil out of the limestone by using a hook machine or a loading machine; 2) transporting the pretreated limestone to a limestone mineral position without the unnecessary topsoil and the interlayer impure soil by using a mine car; 3) mixing the treated limestone and the limestone without the unnecessary topsoil and the interlayer impure soil according to a ratio of 1: 3-5 so as to prepare mixed limestone; and 4) transporting the mixed limestone to the position of a crushing machine, tightly regulating a wall-bar screen of the crushing machine, and carrying out crushing according to requirements. According to the invention, the limestone with topsoil and the interlayer impure soil is pretreated, and the pretreated limestone and good limestone are mixed according to a certain ratio and transported to the crushing machine for crushing, so the crushing machine is prevented from blocking by the limestone; blanking is unobstructed; and the qualified rate of the limestone granularity is ensured.
