Crumb Rubber Production Process

 

Crumb rubber is processed rubber material (bokar) are processed through the stages peremahan.The material itself is processed rubber latex latex garden gardens and clumps obtained from rubber trees.Garden is a liquid latex sap obtained from tapping rubber trees field. This fluid is not experienced either by additional clumping or without pemantap materials.
Raw materials derived from the latex is processed into coagulum and of the lump. Raw materialsThe most dominant is because the processing of crumb rubber lump aims toraise the degree of low quality raw materials into products of higher quality. Stageprocessing include:1. PeremahanBefore undergoing a process of peremahan, bokar cut and washed to remove impurities which mixed in bokar. After it is processed into blankets, which is a sheet with a length of 7-9 m thick, 5-7 mm. This is still wet blanket dried the fastest 10 days to produce a dry blanket. Dry blanket this is further processed into crumb rubber (granula) in diameter (± 5 mm) through the process peremahan in the granulator.Peremahan aims to get the crumbs that are ready to be dried. Propertiesproduced by peremahan is dried so easy to achieve production capacityhigher and the maturity of a perfect crumb.2. DryingDry blanket that has undergone subsequent granula peremahan be dried in the dryer for 3 hours.Entered into the dryer box 12 minutes at a dryer, the dryer temperature to 122oC and 110oC blanket for the WF. Product temperature out of the dryer (rubber temperature before weighing) below 40oC. Drying aims to reduce levels of water to keep it safe limits of insect attacks as well as microbiological, enzymatic and hydraulic. In the drying of factors that could memepengaruhi result is the length of completion, crumbs altitude, temperature and drying time.3. PressingPressing the bale-bale formation of dry rubber crumb. The materials out of the dryer and then weighed 35kg/bandela to be packaged in SW and 33.5 kg / bale for packaging.After that product by using a press machine pressed bale. The size of the presses 60 x 30 x 17 cm.4. Packaging and PackagingThe packaging is intended to avoid absorption of moisture from the environment and free of other contaminants. After the pressed product, then stored on the aluminum table for sorting by using pengutip. After that the product is wrapped with 0.03 mm thick transparent plastic and the melting point of 108 oC. Bale that has been wrapped, then put in containers with interlocking arrangement.
