The invention belongs to the technical field of organic fertilizer processing, and particularly relates to organic fertilizer screening equipment with the low damage percentage. The organic fertilizerscreening equipment comprises a shell, a hopper, a first screening unit, a second screening unit, a third screening unit and an object storing box; the first screening unit is arranged below the hopper and comprises a first motor, a worm, a first driving roller, a pushing device, a first driven roller, elastic conveying belts and a first discharging hopper; the conveying belts are arranged to bea set of narrow cloth belts which are staggered up and down through a set of limiting wheels and are arranged in a layered staggering manner; organic fertilizer particles to be screened gradually falllayer by layer, the material falling speed is decreased, and falling damage due to too high speed is avoided. According to the organic fertilizer screening equipment, the first screening unit is usedfor screening chippings, particles with one particle size range are screened out through the second screening unit, and particles with another particle size range are screened out through the third screening unit; and multi-stage screening is carried out on organic fertilizer, and the damage percentage can be effectively reduced.
