Abstract
A method can be used to cool bulk material in a fine material cooler. The method may involve admitting bulk material to be cooled into the fine material cooler through a material inlet, conveying the coarse material with a first mechanical or pneumatic conveying unit, and conveying the fine material with a second conveying unit in a conveying direction through the fine material cooler to a material outlet. The bulk material may have a fine material proportion of 70% to 95% and a coarse material proportion of 5% to 30%. The fine material may have a grain size of 10-5 mm to 4 mm, and the coarse material may have a grain size of 4 mm to 100 mm.

A method for cooling bulk material in a fine material cooler, the method comprising:
- admitting bulk material to be cooled into the fine material cooler through a material inlet, wherein the bulk material has a fine material proportion of 70% to 95% and a coarse material proportion of 5% to 30%, wherein the fine material has a grain size of 10−5 mm to 4 mm and the coarse material has a grain size of 4 mm to 100 mm;
- conveying the coarse material with a first mechanical or pneumatic conveying unit;
- and
- conveying the fine material independently of the course material with a second conveying unit in a conveying direction through the fine material cooler to a material outlet.
A fine material cooler for cooling bulk material with a fine material proportion of 70% to 95% and a coarse material proportion of 5% to 30%, wherein the fine material has a grain size of 10−5 mm to 4 mm, the fine material cooler comprising:
- a material inlet configured to admit the bulk material to be cooled;
- a material outlet configured to discharge the bulk material;
- a first mechanical or pneumatic conveying unit configured to convey the coarse material;
- and
- a second conveying unit configured to convey the fine material independently of the course material, wherein the first and second conveying units are configured to convey the bulk material in the conveying direction through the fine material cooler to the material outlet.
A cooler for cooling bulk material, comprising:
- a cooler inlet configured to admit bulk material to be cooled;
- a separation region arranged downstream of the cooler inlet in a conveying direction of the bulk material, the separation region configured to separate coarse material and fine material, wherein the coarse material has a grain size of 4 mm to 100 mm, wherein the fine material has a grain size of 10−5 mm to 4 mm;
- a coarse material cooler following the separation region, the coarse material cooler configured to cool the coarse material;
- and
- a fine material cooler following the separation region and arranged parallel to the coarse material cooler, the fine material cooler configured to cool the fine material, wherein the fine material cooler comprises:
- a material inlet configured to admit the bulk material to be cooled;
- a material outlet configured to discharge the bulk material;
- a first mechanical or pneumatic conveying unit configured to convey the coarse material;
- and a second conveying unit configured to convey the fine material independently of the course material, wherein the first and second conveying units are configured to convey the bulk material in the conveying direction through the fine material cooler to the material outlet.
