Problem of bulk materials

That generally cohesive bulk materials do not flow easily in chutes and hoppers.
Changes in moisture and particle size affect the products flowability. These materials
stick to the hopper walls and will negatively affect productivity. Traditional steel
surfaces also become rough and corroded over time, compounding the problems and
increasing the loss in productivity.

Result of bulk material handling problems

1.Delayed start up – Increased cost
2.Limited live storage
3.Spontaneous combustion (stagnant coal)
4.Quality compromised
5.Segregation
al (silo) vibration or shaking
al (silo) structural failure
8.Wear of equipment
9.Process out of control
10.Operator intervention
11.High risk accident

UHMWPE lining Total Solution
Ultra High Molecular Weight Polyethylene (UHMW-PE) occupies the extreme end of
the polyethylene performance spectrum. With a molecular weight ranging from 3 to 7
million g/mol, UHMW-PE lining polymer chains are 10 times longer than conventional
High Density Polyethylene (HDPE).

The properties of UHMWPE lining:

Applying UHMWPE lining as silo Liner
PE-UHMW 1000 properties have meet the full range of material flow, friction and
wear challenge associated with bulk materials.
PE-UHMW excellent properties that needed to handle bulk material are:
1.Very low dynamic friction coefficient (15)
2.Extreme wear resistance (200% higher than stainless steel)
3.Resistance to chemicals
4.Corrosion resistance
5.High impact strength (up to 170 kJ/m2)
6.Service temperature range -260
Benefit of UHMWPE as a lining material is:
1.No incrustations of bulk material
2.No bridging caused in hoppers
3.Enhanced protection of plant and machinery against wear
4.Faster bulk material flow
5.Cost of lining exist hopper with PE-UHMW is one third of the cost of mild steel
6.UHMWPE is half the weight of steel, despite being three times as thick

UHMWPE Lining for silo

Methods of Fastening easily installed UHMWPE lining

Installing UHMWPE  lining must use mechanical joint fastening to chute liner/truck bed liner base

metal or concrete.PEUHMW low friction coefficient makes it  hard to use chemical

joint adhesive.The fasteners bolts should always be made of stainless steel.

Here by methods of fastening PEUHMW sheet as a liner to metal or concrete.

Screwed Capped Bolts

Capped bolts are driven into place with a gun.Then the sheet are

screwed down with carriage bolts and countersunk screws.

Stud Welding

Studs are welded to the metal surface and then the sheets are fitted

by screwing down with seating nuts or hexagon nuts .The sheet is

closed of with superlining plug.

Plugging

Bolting with noncorrosive female thread studs is often used in the case

of concrete hoppers.

Welding the joints 

As an alternative to the methods available for overlapping, joints can be welded using

hotgas extrusion welding equipment. The surfaces to be joined are heated to welding

temperature with hot air, and the extruded compound is dispensed from the welding

equipment with a welding nozzle and pressed into place.

easily installed UHMWPE lining and End Joint Methods

Sheets are typically installed from the bottom to the top, and overlapped or beveled

with a 45º angle.

Thermal expansion and contraction should be taken into account when choosing a

fastening system. Weld washers/plugs and capped elevator bolts are the most popular

fasteners, however the type used depends on the substrate. from the welding

equipment with a welding nozzle and pressed into place.
