Claims
- 1. An apparatus for producing slurry comprising:
- a mill;
- a storage tank;
- a liquid feed means for feeding a first liquid from said storage tank into said mill;
- a solid feed means separate from said liquid feed means for feeding a lumpy solid into said mill, said lumpy solid containing a second liquid therein;
- said mill having a crushing, mixing and stirring means for crushing said lumpy solid in the presence of said first liquid and mixing said crushing lumpy solid and said first liquid to produce a slurry;
- said mill having a heating means for heating said slurry and said lumpy solid and said second liquid to a predetermined temperature such that said second liquid is substantially evaporated while said first liquid is substantially unaffected;
- said apparatus further comprising a removal means for removing said evaporated second liquid and a heat-exchanger means for effecting the exchange of heat from said heated slurry to said first liquid in said storage tank, whereby thermal energy is economized.
- 2. An apparatus as in claim 1, further comprising means for selectively removing particles of said lumpy solid within said slurry having a size greater than a predetermined value.
- 3. An apparatus as in claims 1 or 2, wherein said first liquid comprises an oil.
- 4. An apparatus as in claims 1 or 2, wherein said lumpy solid comprises coal.
- 5. An apparatus as in claims 1 or 2, wherein said second liquid comprises water.
- 6. A process for producing slurry comprising the steps of:
- providing a mill;
- feeding a first liquid into the mill;
- feeding a lumpy solid into the mill separately from the feeding of the first liquid, the lumpy solid containing a second liquid therein;
- crushing, mixing and stirring the lumpy solid in the presence of the first liquid to produce a slurry;
- heating the slurry and the lumpy solid and the second liquid to a predetermined temperature such that the second liquid is substantially evaporated while the first liquid is substantially unaffected;
- removing the evaporated second liquid and extracting heat from the slurry and using the extracted heat to heat the first liquid.
- 7. A process as in claim 6, further comprising the step of selectively removing particles of the crushed lumpy solid having a size greater than a predetermined value.
- 8. The process as in claims 6 or 7, wherein the first liquid comprises oil.
- 9. The process as in claims 6 or 7, wherein the fed lumpy solid comprises coal.
- 10. The process as in claims 6 or 7, wherein the second liquid comprises water.
