"Detchai" is the brand name of the rice mill rubber roller produced by Detchai Rubber  Company. In the local market or ball is named “Sport Man”.The rubber used is 100% synthetic rubber . It has high abrasion resistance. With the abrasion resistant rubber plus the highly selected supplement of grade A the rubber mill can work at least for 50 hours.


 

 
 


  :: Rubber rice roller

The objective in milling rice is to separate the rice husk from the grain. If possible ,the grain should not be broken.Thus Detchai rubber rollers have been designed to meet the need of each type of grains in different rice mills. The strength is in the range of 87 +_5 IRHD Shore A. Besides the size of the roller is an important factor for specifying the rotation speed ( rpm). The size is 10”x10” ( 254mmx254mm).This is the standard size with the suitable rotation speed to cause the slip stick condition. Many customers misunderstand that if the velocity is increased more grains can be obtained. 

But in fact if the velocity is increased the slip stick condition is reduced because the rubber surface’s molecule is wavy across the surface are and the friction between the rubber surface and the milling stone is reduced. The percentage of the husks peeling off is thus reduced


The abrasion between the two surfaces causes heat between them. The tensile strengthand the modulus are reduced. But because of the formula used by Detchai which uses fillers with high tensile strength the abrasion can be lessened by 20 percent from our lab experiment.


The core of the rubber roller is an important part . We have our own factory to produce  these cores. Thus we can design our cores to suit our needs.

 



         
   We have a research unit to measure the rubber by our own high-tech laboratory to keep and control the best quality of our rubber rice roller. 
 




Because of this and other details that our company emphasizes we are confident to Present the Best Number 1 rubber roller in Thailand to you.

:: Rubber brake block


 

 
Ma Li means jasmine in Thai language. Jasmine rice, a world class agricultural product, is a pride of Thai farmers. 
Therefore, Ma Li was chosen as a name of our rubber brake block. 
With the carefully selective materials, high standard production process, and more than 40 years experiences, we bring you an innovation of rice whitening assistance, the rubber brake block 
named “Ma Li”.
