Hammer mill pulverize is used to crush bigger particles into powder form by use of hammer. It is generally used for ethanol plants, fruit juice production, milling grain, sawmills, grinding spices. hammer millspulverize usually consists of a single set of hammers with a single crushing area, and it consists single gear teeth at the upper compartment and a sieve screen is placed at discharge area. While the process takes place in pulverize some of the particles gets struck in the sieve screen and on the gaps between them. In this paper work, an attempt is made to design and fabricate a new hammer mill pulverize which will reduce the particles that getting struck on the sieve and in the gaps between them.so that the labor work required for cleaning the particles will be reduced and increase the efficiency of the machine. Literature survey is carried out on hammer mill pulverize and various optimized hammer mill pulverize. The modelling of the system was designed using solid works and the entire system will fabricated. [ABSTRACT FROM AUTHOR]

In this paper, DMAIC – Six Sigma concept is applied for the selection of suitable polymer composite material reinforced with green natural fibers to make composite wall brick. There were two separate decision-making approaches are obtained from the result of six sigma process and the same has been implemented namely qualitative and quantitative methods. From these two approaches, coir fiber was suggested suitable selection for making this Epoxy based wall bricks. DMAIC framework from the Six Sigma process played a significant role throughout the material selection process with several techniques in each stage. As a result of this, coir fiber was chosen as natural reinforcement material and urethane as epoxy composites in final selection process. [ABSTRACT FROM AUTHOR]

In the arena of Material Science, the advancement of hybrid Metal Matrix Composites has turn out to be a vital area. MMCs offer superior properties compared with alloys. An isotropic material cannot fulfill all the desired properties. Characteristics of MMCs can be customized based on the requirements of numerous applications by appropriate mixtures of reinforcement, matrix, and processing methods. Intention of the present research is to predict the mechanical characteristics of Aluminium based Metal Matrix Composites with the presence of Silicon Carbide and Alumina. Al7075 is taken as a matrix material and Silicon Carbide act as reinforcement. Composite material is developed through stir casting process. The mechanical characteristics of MMC's such as tensile property, fracture toughness and hardness were predicted as per the ASTM standard. Experimental testing has been performed by varying weight proportions of Al7075 (80%, 85% and 90%), SiC (5%, 10% and 15%), and while maintaining all other factors constant. It has been observed that the increasing weight percentage of SiC results with increasing tensile strength, hardness and decreasing impact strength. [ABSTRACT FROM AUTHOR]
