Abstract

The invention discloses a lump mineral crushing and primary screening device which comprises a base. Two first supports, two second supports and two third supports are arranged at the top end of the base, the top ends of the two third supports are fixedly connected with a screening box, the top ends of the two second supports are fixedly connected with a crushing box, an inner cavity of the crushing box is provided with a supporting partition plate and divided into a left cavity and a right cavity by the supporting partition plate, two mutually symmetric rotating shafts are arranged in the right cavity, rollers are arranged on the rotating shafts, inclined second guide plates cover the top of the left cavity, the top ends of the two first supports are fixedly connected with a feeding device, and a fine screening mesh is arranged in the middle of an inner cavity of the screening box. The feeding device slowly performs feeding through vibration, centralized feeding of mineral aggregate can be effectively prevented, overload operation of the inside of equipment is prevented, and lump ores can be simply screened and screened by the crushing box and prevented from entering the screening box and damaging the fine screening mesh of the screening box.

Description

technical field [0001] The invention relates to the technical field of mineral screening equipment, in particular to a bulk mineral crushing primary screening device. Background technique [0002] Sieving is a method of separating particle groups according to particle size, specific gravity, chargeability, magnetic properties and other powder properties. 2. Using a sieve surface with holes to divide the mixed materials with different particle sizes into various particle size levels is called screening. Sieving is the operation of separating solid materials according to the required particle size by using sieves with different sieve sizes. [0003] Ore screening generally adopts a screening machine, and the screening machine shakes to screen ores of different diameters. However, it is not easy to use a screening machine for the primary screening of large quantities of ore. There are large pieces of ore in the primary screening, and the large piece of ore entering the scree...
