Gabion - mesh wire - making process

 Gabion is a large rectangular box of netted wire (mesh) used in civil engineering works. Gabion has long been used as a transition method of construction and engineering for protecting river banks from erosion, for hardening the shoulder of roads and the face of slopes to prevent landslide. Gabion is also used for the foundation of water reservoirs.

The plant itself is a simple one. The most important things are power to move the machineries and transporting the heavy raw materials and products.

Galvanized iron wire is set on an automatic wire netting machine and knitted into diamond shaped wire netting. In order to shape the wire netting into the designated tubular form or rectangular cube form, the backbone framework is made. This backbone framework is

Electrocoating paint processing flow sheet

Electrocoating is a wet paint process used on many parts of products because of its unique ability to resist chipping, scratching, rusting, UV, and the like.  The electrocoat paint covers and protects the entire part or product so that even corners, edges and recessed areas are completely protected.

Edible oil refinery process flow sheet

First process is neutralizing the oil in the neutralizer to remove the Free Fatty Acids (FFA) by adding caustic soda. Then soap stock formed due to chemical reaction is separated from the oil in centrifuge.

Neutralized oil is drawn into the second vessel called bleacher where colour of oil is removed by bleaching process with aid of clay or chemicals such as carbon black and bleaching earth. Oil is generally heated up to 110°C by

Floor Coverings and mat of VULCANIZED RUBBER

Introduction

Floor coverings and mat of vulcanized rubber are flat colored and patterned piece of material used to cover floors of houses and automobiles. Since they are washable with water and durable in comparison to other type of floor coverings, they are widely utilized for covering the floors of automobiles.

Raw materials

The major raw & auxiliary materials for the production of floor covering and mat of vulcanized rubber are natural and synthetic rubber, carbon black, process oil, whitening powder, zinc oxide, stearic acid, anti oxidant, normal sulfur and accelerator.

Process Production

The manufacturing process of floor coverings and mat of vulcanized rubber can be broadly be classified into three stages, mixing, building and vulcanizing process.

Rubber is mixed with other ingredients

Production Process

Different vodka manufacturers employ several variations to the vodka manufacturing operation; however the basic vodka manufacturing process is pretty simple and presented as follows:

Mash preparation

The grain for example in the form of wheat or vegetables is put inside a mash tub. The tub is very similar to a washing machine. While the tub rotates it breaks down the grains. Ground malt is

Silk Yarn Production Process

Raw materials

The main materials are silk fiber, Spools, cops, reels and cons.

Production Process

Hatching of eggs

Sericulture, or the raising of silkworms, involves the incubation of the tiny eggs of the silk worm moth until they hatch and becomes worms. After hatching, the worms are placed under a layer of gauze, on which is spread a layer of finely chopped mulberry leaves. For six weeks, the worms eat almost continuously. At the end of this period, they are ready to spin their cocoons, and branches of trees or shrubs are placed in their rearing houses.

Silk Production

The worms climb these branches and make their cocoons in one continuous thread, taking about eight days for the process. The amount of usable silk

Recycled plastics making process

Recycling plastics

It involves the following major operations:

o Granulation

o Washing

o Drying

o Extrusion and pelletizing

o Packing

Alternative Plastic recycling technology:  

Mechanical recycling 

Mechanical recycling of plastics refers to processes which involve the melting, shredding or granulation of waste plastics. Plastics must be sorted prior to mechanical recycling. Technology is being introduced to sort plastics automatically, using various techniques such as X-ray fluorescence, infrared and near infrared spectroscopy, electrostatics and flotation. Following sorting, the plastic is either melted down directly and molded into a new shape, or melted down after being shredded into flakes and then processed into granules called re-granulate.
