Multistage screening and crushing linkage machine and screening production line thereof

Abstract

The invention discloses a multistage screening and crushing linkage machine and a screening production line thereof. The multistage screening and crushing linkage machine comprises at least two standcolumns, a first driving device, a multi-layer sieve and a crushing device, wherein the first driving device is used for driving the stand columns to swing, the multi-layer sieve is used for screeningore, and the crushing device is used for circularly crushing the ore; the multi-layer sieve comprises primary screening sieves and a finished product sieve, wherein the primary screening sieves are located above the finished product sieve, and the primary screening sieves and the finished product sieve are hinged to the two stand columns; and a feeding case of the crushing device is arranged on one side of a first discharge outlet of the primary screening sieves, and a discharging case of the crushing device is located above the primary screening sieves. According to the multistage screeningand crushing linkage machine and the screening production line thereof, the multi-layer sieve is divided into multiple layers, the screening efficiency is high, the multi-layer sieve is designed basedon a parallelogram-shaped planar connecting rod mechanism, the motion mode of the multi-layer sieve adopts large-amplitude swing for replacing an existing vibrating sieve, and the phenomenon that sieve pores are blocked by ore blocks is greatly reduced.

Description

technical field [0001] The invention relates to a multi-stage sieving and crushing linkage machine and a sieving production line thereof, which belong to the technical field of stone ore crushing equipment. Background technique [0002] In the production process of ore products, it is often necessary to crush and sieve the ore to achieve the particle size required for powder making, but the linkage between the crushing and sieving equipment is poor, and a long conveyor belt is required between the crushing and the vibrating screen The floor area is large; the vibrating screen mostly uses a vibrating motor as the vibration source, and the vibration force of the vibrating screen is small, and the phenomenon that the quarry blocks the screen hole often occurs, which is not suitable for the screening of ore blocks; the discharge rate of the screening process is low, resulting in fine particles. Low yield. Contents of the invention [0003] In view of this, the present inventi...
