Galvanizing: Zinc Ash recovery system.

When you are a galvanizer, you will face some waste to treatment includes Rinse water, Spend acid, Sludge, Dross, Ash...etc. Some of them are valuable like dross and Ash; some of them need to pay for treatment like spend acid or sludges. Today we would like to introduce our Ash recovery system, even ash is a valuable product but we still can get more add values. 

The ash will be created each dipping than workers are skimming to the side for quality reason. When ash accumulate more and more, workers will scoop up ash from kettle to drum. This is the traditional practice, Some Asian countries will ask workers to re-fill ash on kettle then pushing till ash color changes, but it will create lots of fumes and it is hard jobs. So it was not easy to teach workers to scoop the ash from kettle, it needs experience accumulation and practices harder. Once you have a machine, you don't need to worry the worker creates money loss.

Our system is easy to operate. Worker scoops ashes into our drum directly beside the kettle. When the drum has 80% full (Max. 800kg/drum) then put the cover on and move it into our system by forklift. After 4 hours machine running, open the hole on the drum you can get the metal zinc back. Then let the drum cooling remove residues from it will complete a cycle. 

The calculation:
If ash created 800 kg/day and recycle one drum per day.
Our average recovery rate is 70%
The zinc price base on USD 2,000 / ton for calculation as below:
  1. recycled zinc value:(0.8 ton × 70%) × USD 2,000 / ton = $ 1,120
  2. residues value:(0.8 ton × 30%) × USD 2,000 / ton × 10% = $ 48
  3. ash price:0.8 ton × USD 2,000 / ton × 40% = $ 640
  4. max fuel cost:16 m3/H × 4 H × 0,7 USD/m3 = $ 44.8
  5. worker/amortization:$ 40/drum. day

The BENEFIT = (1) + (2) - (3) - (4) - (5) = $ 443.2 per day

If your ash created 20 tons per month, then you can save $ 11,000 per month.
The system ROI will less than 6 months!!!

Below are some of our system photos.

Galvanizing: Zinc pump

If you are a galvanizer, did you out source the kettle change to other company or you handle the job by yourself? what ever your decision you must to have a reliable pump.

Our pump is made in Taiwan with frequency control, (It can adjust the pump speed for fitting worker tempo.) It also can dipping to bottom of kettle. (don't need to move down with zinc level). The blade around 100mm hight which can make sure remain zinc level less than 100mm. (less weight for kettle lifting.)

RUF press system technology (briquette machine)

Welcome to RUF, your Partner for sustainable cost optimisation! 

RUF system technology is worldwide employed to profitably reduce the volume of shavings and swarfs, to recycle wood and compress biomass. RUF Hydraulic machines compact saw dust, wood chips, bark and wood dust and biomass such as peat, hay and miscanthus. Even residues such as paper, cotton, styrofoam or dusts can be disposed of safely and clean by means of a briquetting machine. RUF metal presses compact scrap metal, aluminium, steel and castings. They a improve the melting yield, drain-off water and de-oil. RUF Briquetting systems offer a compact solution for almost any kind of organic and inorganic material.
