Description
Technical field
The utility model is related to coal preparation plant's coal slime and the mixed uniformly technical field of lump coal, and in particular to a kind of coal slime in small, broken bits
With the uniform hybrid system of coarse grain lump coal.
Background technology
Filter press is the equipment of checking on that coal preparation plant's fine coal de-watering is reclaimed.The filter cake of filter-pressing coal slime has that viscosity is big, moisture
Height, the characteristics of be bonded to cake, has more preferable selling price and approach to allow filter-pressing coal slime, generally require to its it is broken after it is equal again
Even to be mixed into other coal selecting products, such as flotation effect is influenceed by many factors in floatation process, floatation clean coal filter press
The quality of coal slime can have more preferable, more stable Sales Channel, by floatation clean coal in certain interval fluctuation in order to allow floatation clean coal mud
Mud and gravity treatment cleaned coal are uniformly mixed into the production marketing that homogenizes；For another example tail coal mud cake of filter-press, it is generally broken after with
Middle coal is uniformly mixed into the production marketing that homogenizes；Present coal preparation plant is generally entered to coal slime using single blender with lump coal
The uniform mixing of row, as disclosed in Chinese patent literature CN104437188A " blender "；Current technology generally existing problems with,
1. the service behaviour too according to heavy equipment in itself, have ignored for equipment provides good condition of work from process system, 2. side
Method imperfection, material has in follow-up transport and blanking operation and bonds blocking phenomenon again.
Therefore, those skilled in the art need a kind of significantly more efficient, perfect coal slime in small, broken bits of offer badly and coarse grain lump coal is equal
Even hybrid system and its method.
