TrumpJet®Concept

Effective flash mixing of chemicals close to PM headbox brings considerable cost savings together with environmental benefits. TrumpJet patented techonology (US patent) makes it possible to use stock, white water or filtrate containing solids instead of fresh water. TrumpJet flash mixing reduces the amount of chemicals needed, saves energy and reduces carbon dioxide emissions.

TrumpJet®flash mixing versus conventional mixing

See the difference between flash mixing versus conventional mixing 
in the video below.

1. Pioneer innovation

Pioneering innovations challenge conventional process chemistry and efficiently cut raw material costs with sustainable results.

TrumpJet with three nozzles provides instant mixing without delay.

Complete and effective mixing with the main flow allows dosing stations to be installed close to the headbox. It enhances the effects of chemicals. The response time is quick and there is no chemical losses.

2. Pioneer innovation

Clean headbox feed stock completely eliminates use of fresh water or any filtrate- saves energy used to heat up fresh water/filtrate.

ADVANTAGES OF FLASH MIXING ADDITIVES CLOSE TO HEADBOX WITH TRUMPJET®:

  • Efficiency of chemicals will be increased due to thorough powerful flash mixing and very short delay time in process before dewatering and sheet formation.
  • Recirculation of chemicals in the approach flow system will be
    practically eliminated, which further increases efficiency of chemicals and improves
    operational efficiency and product quality
  • Mixing several chemicals together simultaneously will give extra boost for efficiency
    of chemicals, bringing additional savings

ALL THESE LEAD TO SAVINGS IN CONSUMPTION OF ADDITIVES/CHEMICALS, FRESH WATER, AND ENERGY. SAVINGS WITHOUT OPERATIONAL ISSUES (BUILDUPS, HOLES, BREAKS, PROFILE PROBLEMS ETC.) ARE ONLY ACHIEVED WITH COMPLETE FLASH MIXING TECHNOLOGY, WHICH GUARANTEES GOOD DISTRIBUTION AND DISPERSION OF ADDITIVES/CHEMICALS IN HEADBOX STOCK.

Complete flash mixing allows installing dosing stations close
to the headbox

The efficiency of chemicals deteriorates the longer they stay in process

chemical

When dosed close to headbox efficiency of chemicals will be increased due to less time in process before dewatering. Average delay time in position B is only less than a minute compared to thick stock dosing of 7–10 minutes.

The advantages are possible only if mixing is done:

  • by using high mixing energy
  • by using headbox stock as injection media
mixing comparison

High mixing energy is necessary for proper mixing of additives = Good dispersion and good distribution of chemicals and additives.

Unlimited use of headbox flow as injection media allows to increase mixing energy to a right level, which guarantees good dispersion and good distribution of additives in stock flow to headbox.

Using white water from other sources (white water, filtraits, etc.) create operational problems due to impurities and variations. Badly dispersed and distributed additives can further deteriorate PM efficiencies and product quality.
