Design and experimental study of a conical lattice divider suitable for 3 mm particle size
In response to the high demand for material supply 0f he divider,the author developed a 3 mm conical lattice divider and conducted experimental research on it.The research conclusion was:the number of lattices on both sides was 12,the average width of the lattices was 10.52 mm,the coefficient of variation of lattice width was 12.97,which meet the requirements.The coal sample flowed smoothly,the average mass deviation of the retained samples on both sides after dividing was 0.56%,which meet the requirements.The precision of the divider meet the requirement,and both retained samples after dividing were unbiased.Using a 3 mm conical lattice divider as the equipment method and the 3 mm divider as the national standard method,the equipment method could replace the national standard method.The 3 mm conical lattice divider could reduce the difficulty of operation and minimize the error in sample preparation.
