Waste and dust are usual by-products produced during the early stages of cotton working and represent a possible source of pollution for the work environment.

The pneumatic haulage of the crude materials, along with either the integral or partial fairing of the production machines, can help prevent the dust from being scattered all around the working area.

It is however vital to provide an effective dust collection and suction system to remove waste’s fibrils and dust from inside the machines as well as from the air outlets.

In particular the removal of the wastes discarded by blowing and carding nowadays is only obtainable through substantial, realiable and mechanised suction, conveying and collecting system, thus avoiding any manual as well as hard and unpleasant work.

MAZZINIICI has been working for several years in this specific field and is able to offer different and complete solutions for fibre and dust separation.

The choise of the most suitable solution is entrusted to the competence and experience of our engineering department, where each single determining factor is thoroughly examined, case by case, thus achieving optimum results together with a drastic reduction in energy requirements.

The system uses different separators, fitted to the type of waste and its possible reutilization, as shown on the enclosed flow-sheet diagram.

The diagram concerns a typical solution where it is performed a continous suction both of the air exhausted by the condenser of the supply line and the air used for waste suction.

The dusty air coming from the above mentioned circuits attains one or more inertial separators , whose essential prerogative is the lack of mechnical device, thus assuring operating simplicity together with a virtually nil maintenance.

Wastes and fibrils, separated from the finest dust, are definitilively exhausted by a small final fiber compactor .

As an alternative to this last solution. The massive air volume, flowing from both circuits, could attain a high-capacity condenser-separator unit, from which the wastes, containing most of the fine dust, are exhausted in the form of a mat. This procedure permits not only the heaviest wastes to be separated from the technological air, but also the dust to be subjected to a prefiltering action.
The wastes exhausted can be directly let into the baler hopper or on an opener conveyer belt.

In both solutions, the final air filtration is obtained through an automatic filter, equipped with suitable filtering media, that holds the dust and fibrils.

These residuals are systematically removed by some aspirating nozzles and then conveyed into special containers.
