Title

BRIQUETTES FROM MAIZE COBS AND CEIBA PENTANDRA AT ROOM TEMPERATURE AND LOW COMPACTING PRESSURE WITHOUT A BINDER

Pages

  1-7

Abstract

 This paper reports the findings of densifying ground MAIZE COBS and CEIBA PENTANDRA sawdust at room temperature using low compacting pressure without a binder. The MAIZE COBS were crushed using a hammer mill. Particle sizes of MAIZE COBS and C. pentandra used for the study were£1 mm. The two materials were combined at mixing percentages of 90:10, 70:30 and 50:50 (C. pentandra/maize cobs). BRIQUETTES were produced using a laboratory hydraulic press. Compacting pressure was varied from 20 to 50 MPa at an interval of 10 MPa. The results indicated that the RELAXED DENSITY of BRIQUETTES produced from particles of MAIZE COBS only ranged from 541 to 659 kg/m3 whilst that made from a mixture of MAIZE COBS and C. pentandra ranged from 565 to 774 kg/m3. COMPRESSIVE STRENGTH in cleft of BRIQUETTES produced from MAIZE COBS only ranged from 0.12 to 0.54 N/mm whilst that produced from a combination of MAIZE COBS and C. pentandra ranged from 7.72 to 59.22 N/mm. Additionally, at all compacting pressure levels, BRIQUETTES made from MAIZE COBS only had an IMPACT RESISTANCE INDEX of 0%. Whilst those made from a combination of MAIZE COBS and C. pentandra ranged from 115% to 500%. Thus, BRIQUETTES with adequate physical and mechanical characteristics could be produced from MAIZE COBS at room temperature using low compacting pressure when MAIZE COBS are combined with sawdust of C. pentandra. These findings could enhance the existing technology for densifying agricultural residues, for example, MAIZE COBS, especially in rural communities.
