For better realizing goal of the invention of the present utility model, can further by its refinement;
Be made up of two magnetic separation rollers arranged side by side at described sorting unit further.
Between described motor and magnetic separation roller, reductor is installed further, shaft coupling, bearing block.
Bottom further in described separation chamber is provided with sub-material dividing plate.
On the outer wall of described separation chamber, just sub-material dividing plate adjustment door is being provided with to the position of sub-material dividing plate further.
The utility model classification dry-dressing machine is according to the difference of material of different grain size magnetic separation characteristic, first pan feeding is divided into size fractionated, and then carry out dry separation operation and effectively can improve the efficiency of separation, adopt the magnetic separation roller of different field intensity and different linear velocity to sort supplied materials according to material of different grain size simultaneously, thus substantially increase sorting index, reduce tailings grade simultaneously, reduce metalliferous mineral loss.
With conventional dry optional equipment ratio, the beneficial effects of the utility model are:
1, magnetic separator separation chamber top is provided with vibrosieve charging gear, before material carries out dry separation, carry out pre-classification to material;
2, sorting unit is made up of two magnetic separation rollers arranged side by side, and material of different grain size carries out sorting operation by different magnetic separation roller respectively, effectively can improve the efficiency of separation;
3, in separation chamber, the magnetic field intensity of two magnetic separation rollers arranged side by side and magnet drum linear resonance surface velocity are selected respectively according to material of different grain size characteristic, effectively can improve sorting index, reduce metalliferous mineral and run off;
4, the utility model can be installed and used according to the scale of practical object and feature, also can form complete approved product, and Plant arrangement is flexible, and construction is simple;
5, this classification dry separation equipment only needs the simple operations of execute-in-place work and maintenance, investment and operating cost low, actual effect is good, is applicable to iron ore pre-selecting before grinding and throws useless operation.
