HNI DRUMS

NEW JUMBO TECHNOLOGY FOR WOOD AND POLYPROPYLENE (PPH) NEW JUMBO Drums are highly reinforced drums with 4 long shelves inside, permitting usage of increased volume of the drum with a substantial higher loading factor. All NEW JUMBO advantages apply for both WOODEN and PPH drums.

MAIN PROVEN ADVANTAGES

MORE than 60% higher loading factor compared to traditional drums thus resulting in less floor space needed . The NEW JUMBO philosophy is ideal to increase productivity without occupying more factory space by either transforming standard drums or replacing existing drums with NEW JUMBO drums

Big flexibility in load factor, directly connected with the lifting capacity of each shelf at each drum revolution resulting in typical NEW JUMBO hide movement.

Minimum 30% of water saving,

Substantial savings of chemicals. I some cases customers reported more than 7% of chemical saving in the RETANNING/DYEING operation in PPH TT drums

Better mixing and homogenization effect on the float with better and higher absorption and exhaustion of chemicals, explaining also above savings of chemicals and reduced effluent load!

More than 50% of energy savings compared to traditional drums. In various installations

we could prove savings of more than 100% of absorbed energy!

Smooth working of drum with reduced speed, some customers report also area gain up to 5%!

THE ONLY TRUE NEW JUMBO CONFIGURATION GIVING ALL ABOVE ADVANTAGES IS WITH 4 NEW JUMBO SHELVES. THE PATENTED PARTICULARLY ANGLED SHELVES ARE THE MOST IMPORTANT FACTOR IN THE NEW JUMBO CONFIGURATION. NO OTHER LONG SHELVE CONFIGURATION IN THE MARKET COMBINES ALL THESE ADVANTAGES

The additional loading capacities of the JUMBO drums require the largest possible door opening for best unloading Our 140x140cm automatic vertical door thus is an important advantage of Hni drums

MECHANICAL CHARACTERISTICS AND REINFORCEMENT All Hni drums have been carefully analysed and engineered with latest computer simulation technology adding to our decades of experience! These kind of simulations indicate clearly which parts need special reinforcement in order to resist the enormous additional torque forces of the NEW JUMBO drums

Particular attention has been paid to the dimensions and quality of construction materials and type of introduced reinforcements (more and stronger hoops for wooden drums, more and stronger reinforced bolts, special strengthening on of the drum bottom, higher material grades of casting components)

Quality and structure of cast iron components (particularly crown wheel and cross)have been carefully analysed and dimensioned to be able to transmit the high torque factors. The complete transmission line (crown wheel and its teeth, pinion, gearbox, motor and brake) have been specially designed and reinforced compared to standard drums in order to give a long and maintenance free operation of the drums

POLYPROPYLENE (PPH) DRUMS By now Polypropylene material has been used for drums for over 15 years and hundreds of drums are working successfully in the market.

We have already been using polypropylene material for preparation tanks for over 40 years and some of those tanks are still in use today. Mechanical properties and usage of PPH material show less consumption than wood, and some wooden drums are in operation for over 30 years

ADVANTAGES OF HNI POLYPROPYLENE (PPH) DRUMS POLYPROPYLENE DRUM IS A POSITIVE MIX BETWEEN THE STAINLESS STEEL DRUM AND THE WOODEN DRUM, HAVING THE ADVANTAGE OF BOTH WITHOUT HAVING THEIR DISADVANTAGES.

Easy cleaning inside and outside of the drum, giving the advantage of using the same drum for different colours and application without restrictions as they exist in wooden drums

Better thermal insulation compared to stainless steel drum and surprisingly also better compared to

the wooden drum, thus better conditions for the process. Energy savings

Chemical resistance of PPH is better compared to wood and stainless steel, thus opening areas of use for PPH where wooden and stainless steel drums would fail in short time. Mention here is made of the resistance to the following chemicals: hydrogen peroxide, caustic soda, sodium sulphide, organic acids, ammonia, chloric acid and sulphuric acid at highest concentrations!

More internal volume and therefore more loading compared to wooden drums of the same external

dimension, depending on drum dimensions (and therefore thickness of the wood) the volume of PPH drums is approximately 11-18% higher

Lower weight and therefore less mechanical force on drive and foundation

Lower price compared to quality stainless steel drums

No need of swelling time compared to wooden drum, therefore PPH drums are ready for production

in a few days after arrival.

Easy repear in case of damages

Any inside configuration (Standard, shelves, pegs, triplex drum, 2 compartment drums, JUMBO drum) is possible with the PPH drum.

Also the usage of material over time has been analysed and we can confirm that the usage of PPH is less

than the wood, therefore longer life time of the PPH drum compared to both Stainless Steel and wood!

Cost effective reuse of existing wooden drums parts. We offer various rebuild possibilities where existing components can be fully or partially reused (armatures, drive systems, pillars and supports, control panels, installation etc), thus giving a possibility of getting full advantage of a new PPH drum body with existing parts with limited budgets!

For some special applications all inside parts of our PPH drums are completely covered with PPH where no stainless steel parts are allowed due to its chemical reaction to certain chemicals

PPH TT DRUMS Hni has introduced a completely new unique production technology of PPH drums Different than from our PPH AGI drums the TT construction does not need joint welding on the outside. We call this new technology TT-Technology. These cylinders are produced on special machines guaranteeing maximum stability and mechanical resistance. Main characteristics are:

! No outside welding, thus reduced tensions! ! No outside reinforcements (hoops, metal frame) thus optimal construction according to plastic material

construction and no maintenance. All necessary reinforcements are done inside. IT IS A FUNDAMENTAL CONSTRUCTION MISTAKE TO MAKE A CAGE OUTSIDE AS OTHERS DO. THIS MUST BREAK SOONER OR LATER BECAUSE PLASTIC MATERIALS HAVE THEIR ELONGATIONS THAT NEED TO BE CONSIDERED ! Any colour (we have chosen black but any other colour could be produced). ! Diameters: 3600, 3000mm. Others on request

NEW JUMBO PPH RE-TANNING/DYEING DRUMS (TT AND AGI) Hni is the only company in the world offering these type of drums with the proven patented NEW JUMBO advantages. No other company in the world has the know-how and production capacity to produce NEW JUMBO TT drums!

If production needs to be increased in the same space available then NEW JUMBO drums are the solution!

Biggest automatic vertical door available in the market is very useful for fast loading and unloading

PPH LABORATORY AND SMALL PRODUCTION DRUMS Polypropylene drums are more and more requested for laboratory and small production lots, where the main advantages like easy cleaning and flexible lot sizes (Jumbo Drums) are playing an important role. Same as all Hni PPH drums, these drums are available in all different inside configurations. We offer the LAB and SMALL PRODUCTION PPH drums in both Standard (peg/ standard shelves) and NEW JUMBO versions
