- Abstract
The lubricating oil sludge from steel wire drawing factory contains organic compounds mainly of fatty acids, which has good binding property and combustion performance. In this paper, briquette is prepared from pulverized coal with this industrial sludge as binder. The viscosity of sludge was tested to be 2.44 Pa•s. The effects of sludge content, forming pressure and drying time were studied by single factor test. The falling strength of briquette was increased first and then decreased with the increase of forming pressure from 6 MPa to 14 MPa, and the suitable forming pressure was determined to be 12 MPa at last. The suitable sludge content was determined to be 16% because too much sludge would lower the strength of briquette. Under the conditions of sludge content of 16% and forming pressure of 12 MPa, the cold compression strength of briquette reached maximum when the drying time was 12 h, and then tended to be stable. Based on the results of single factor tests, the optimum conditions are as follows: 12 MPa of forming pressure, 12 h of drying time, 16% of sludge content.
