Fire is the major hazard in conveyors of any industries. Reasons of fire many which can produce ignition in conveyors like- coal material accumulate, rubbing the belt, friction in between conveyor. To eliminate the any fire incident in tunnel conveyors provide a fire fighting system which is running in auto mode. This auto mode system works when temperature rise above 65 0 C sensed and then water spray in the conveyor and control or eliminate a big fire incident. This paper present modification in manual mode fire fighting ststem to auto mode fire fighting system in tunnel conveyors.

Losses of conveyor belt due to rupture caused by foreign materials is the major losses of belt in conveyors of any industries Reason of full length belt cut due to foreign material stuck in skirt board . To eliminate the full length belt cut due to foreign material stuck in skirt board provided a Belt Rupture Devices (BRD) in all conveyors after the receiving chute at 5-10mtr distance. Whenever belt get through cut, carrying material will fall on the BRD plate.The moment material weight become more on the BRD plate then the counterweight of the BRD (hardly max 300 gms), limit switch will operate & belt will be stopped and thus prevent further damage to the belt.

The production and/or worldwide consumption of chicken at an industrial or domestic level lead to a considerable quantity of chicken feather residue as a waste by-product. Chicken feathers have a possible application in preparing lightweight composites. The use of chicken feathers as a constituent to prepare hybrid composites leads to a solution for disposal of the feathers. In this study, chicken feathers were used as filler material to prepare hybrid composites. Different varieties of composites were prepared by a chicken feather hand-layup technique, and by varying the percentage weight of the chicken feathers. Specimens were prepared and tested according to ASTM standards. The 10 wt. % chicken feather-filled hybrid composites indicated the maximum tensile strength (193 MPa), flexural strength (148 MPa) and impact strength (3.65 Joules). Scanning Electron Microscopy (SEM) analysis was carried out to find the fracture and interfacial characteristics of the composites. The results indicated that, these composites can be used in domestic, automobile and structural applications which carry nominal loads.

In recent years advanced polymer material composites are used to manufacture a fishing boat in glass fiber with polyester resin. To enhance the properties of GFRP, in this work, cement was used as filler material with glass fiber - polyster resin matrix. The composites were fabricated by varying the weight percentage of cement in matrix material, 0 wt%, 5 wt% and 10 wt% respectively. The composites were fabricated by hand- layup process, following with compression molding. As per ASTM standards, the specimen were prepared and studied experimentally for mechanical properties. The results were compared for different percentage of filler material. It was observed that addition of cement lead to increase in mechanical properties of GFRP.

This paper presents the recent trends in the mechanical characterization of composite materials with different fillers materials to make it a hybrid composite.

The unique and diverse characteristics of composite materials have increased their utilization worldwide industrial applications. The use of fiber reinforced composite materials is becoming more popular due to their high strength to weight ratio combined with easy manufacturing methods. The present work is focused on to analyse the influence of chicken feather as filler materials on the mechanical behavior of Eglass fiber, reinforced in unsaturated polyster resin matrix. Different types of composites are fabricated using 5wt% chicken feather, 7.5wt% chicken feather and 10 wt% chicken feather with 50% wt fiber, rest matrix material. The composite is manufactured by hand-layup process. Specimens were cut and tested according to ASTM standards. The mechanical properties were studied viz:, tensile strength, bending strength, impact strength and hardness of the material. The results were compared for different percentage of filler material.

The unique and diverse characteristics of composite materials have increased their utilization worldwide, from featherweight fly fishing rods to high performance airplane parts, the use of fiber reinforced composite materials is becoming more popular due to their high strength to weight ratio combined with easy manufacturing methods. Fiber reinforced polymer matrix consists of reinforcing fibers and polymer resin. The fibers are considered as the main load carrying constituent of the composite, while the role polymer matrix is to transfer and distribute the load between fibers as well as provide corrosion resistance, damage tolerance and thermal environmental stability. Here, the primary objective is to determine mechanical and chemical properties of glass/epoxy composite with asbestos as filler material in different percentage. The composite is manufactured by hand-layup process. Specimens were cut and tested according to ASTM standards. The mechanical properties were studied viz, tensile strength, bending strength, impact strength and hardness of the material. The results were compared for different percentage of filler material.

This paper represents the study of drilling characteristics on hybrid composite using conventional twist drill. Drill tool dynamometer has been utilized to measure the thrust force and torque. L16 orthogonal array has been selected for the study and experiments have been carried out on the bases of the selected orthogonal array. The ANOVA have been deployed to study the influence of process parameters on the thrust force and torque. Regression equations have been formulated for estimating the predicted values of the thrust force and torque

Composite materials play a vital role in many industrial applications. Research scholars are working on fabrication of new composite materials worldwide to enhance the applicability of these materials. In view of this, the present work is focused on to analyse the effect of hematite ore content on the mechanical behaviour of Bi- directional weaved E-glass fiber, reinforced in Orthophthalic polyster resin matrix with methyl ethyl ketone peroxide catalyst and cobalt octet accelerator were used with hematite ore filler.

The ultimate objective of manufacturing industries is to increase productivity with high quality. At present, many manufacturing companies are facing problems such as high quality rejection, high inventories, high lead time, high costs of production, and inability to cope with customer orders. By implementing and practicing the lean production system many problems can be solved without employing high-tech and high-touch approaches but by involving people on the shop floor in Kaizen activities. Kaizen is one of the powerful tools of lean manufacturing. Kaizen refers to continuous improvement in performance, cost and quality. Kaizen ensures that manufacturing processes become leaner and fitter, but eliminate waste (problem) where value is added. The main objective of this paper is to provide a background on kaizen, present an overview of kaizen concepts that are used to transform a company into a high performing lean enterprise. A case study of implementation of Kaizen‟s has been discussed
