A sample splitter is formed by a chute that is sloped towards its discharge end and is oscillated back and forth on a horizontal path that is substantially perpendicular to the axial center line of the chute. The chute itself is substantially symmetrical on opposite sides of the axial center line and the walls are sloped upward so that the material forming the sample to be split moves along the chute with a sliding or rolling action back and forth across the axial center line of the chute without significant bouncing of the discrete pieces of the material. An elongated V-shaped plow is positioned at the discharge end of the chute with the apex of the plow forming a substantially straight line that is in axial alignment with the center line of the chute at the mid-point of the oscillation of the chute. The oscillation motion of the chute causes the material of the sample to slide down the chute and to be projected off the discharge end on one side or the other of the apex of the plow.
A sample splitter for particulates or small elements comprising at least one chute slopped downwardly from a rear end towards a discharge end, means for oscillating said chute on a substantially horizontal path substantially perpendicular to the axial center line of said chute, said chute being substantially symmetrical on opposite sides of said axial centre line, side walls on said chute on opposite sides of said centre line, said side walls being slopped upwardly in a manner such that the material forming said sample moves with a rolling or sliding action in a zig zag path on said chute and without significant bouncing of the material down said chute as said chute is oscillated, an elongated V-shaped plow at the discharge end of said chute to intercept material issuing from said chute, the line forming the apex of said V-shaped plow being substantially in alignment with axial centre line of said chute when said chute is at the mid-point of its oscillation.
