Liner UHMW Polyethylene Sheet for Granulation Machine Corrosion
Resistant in Fertilizer Industy
Di-ammonium workshop of one chemical plant, the temperature of
granulation machine is 90-95 degree Celsius. In the past, they used
rubber sheet as liners, but the service life of rubber sheet was
only 6 months. As the temperature is too high, the rubber liners
were easy to deform, damage and stick material. So the sizes and
shapes of the productions were not round and symmetrical.
Then they installed UHMWPE liners manufactured by our factory (
Hongda Engineering Plastics Factory). The liners do not stick
material or pilling, which also reducing the load of the
equipments, saving power energy and reducing production cost. Also
the sizes of products are symmetrical and shape are round.
Cost Diferrences Between Rubber Liner and UHMWPE Liners
Bellow we would like to calculate the cost here ( the unit is RMB,
now the exchange rate is 6.3).
Material Cost: Rubber liner sheet for one set is around 40,000, the
service life is half a year, so need 80,000 a year. Need of 20 pcs
of UHMWPE sheet as liners, and total cost is 54,000, so there will save 26,000.
Labor Cost: we calculate according 6 person group, 200 x 3D = 3600.
So if UHMWPE liners will save 3600 labor cost.
Production Cost : we calculate according to specification of
granulation machine3.6m X 6m. Install one set liners need to stop
production line for 3 days, so there will be 3000 tons less production for 3 days.
We just calculate cost here for one year, the service life of our
UHMWPE sheet is at least a year.
Seen from above we know that rubber liner sheet seems cheaper, but
indeed it is not. As the labor cost and production cost caused will
High temperature Resistant
Low moisture absorb, so non-stick of material
