Juli column crusher can realize a highly-efficient crushing process by grinding and crushing the material with rollers and pushing and screening at the same time. There are powerful crushing mediums and a set of pushing device in the crushing chamber. The crushed particles of acceptable size are squeezed out of the column crusher from the small sieve holes and become qualified products, while the unqualified particles are pushed forward and crushed continuously by the rollers until they are qualified and squeezed out of the machine after times of crushing.
Features:
1, Particle size produced by Juli column crusher and system ≤ 8mm; less powder; the distribution curve falls into the theoretical distribution range of the boiler;
2, Turn two-stage crushing into single-stage crushing, the maximum particle size of feeding coal for the preparation system is up to 300mm;
3, Drying and impurity treatment are not required for the sticky and wet coal or the coal containing many impurities;
4, Replace multiple screening machine with single pneumatic sorting machine, which improves sorting efficiency and the service life oft wearing parts is up to several years;
5, Preparation system works under negative pressure, with advantages of no pulverized coal, low noise and good working environment;
6, The technology of the coal preparation system is simple and quantity of equipment are reduced; therefore, the operability, the maintenance and the reliability of the system are greatly improved;
7, Both electricity costs and worn parts costs for the preparation system can be reduced by 50%;
8, Significantly reduce investment costs for the power plant.
