Dry Feeders

POLICENDOS

Construction Features
■ Variable capacity powder dosing unit,hopper with powder level indicator,worm screw with bridge breakerscrapers
■ Water inlet and regulation unit,solenoid valve,pressure switch,disperser nozzle
■ Preparation tank with covers,dividedinto the three sectors of dissolving,maturing and storage
■ Control and command electricalswitchboard including theautomatisms and indicators for fullyautomatic plant running
■ Solution dosage system,generallyconsisting of dosing pumps selectedfrom the numerous versions availablefrom our range (ask for the specificcatalogue)

Function
The preparation tank is divided into three sectors:dissolving V1,maturing V2 and storage V3,interconnected by siphons that form a preferential path necessary for the formation of a topquality solution.The powder from the dosing unit comes into contact with the water,which,appropriately sprayed,from a nozzle,carries out the important action of dispersion.
The water/powder mixture then drops into the tank below where the dissolving phase begins.In dissolving sector V1 a slow agitator keeps the contents of the tank in movement,thusfavoring homogenization of the solution.
The siphon transfers the solution to the maturing sector V2 where another slow agitator keepsit homogeneous until maturing is complete.Then the solution is transferred to storage sector V3from which it can be transferred for use.
The level switches installed in this sector controlplant automatic functions:
High and normal level switch:when the solutionreaches the high level this switch stops the powderdosing unit and closes the water inlet solenoid valve.In the normal level position it enables dosing unitfunctioning and opens the water solenoid valve.
Low level switch:when the solution falls tominimum level this switch stops the dosing pump andlights up an alarm indicator on the electrical switchboard.

POLYMAN

Plant for manual preparation of polyelectrolyte
Polyelectrolyte solution is not very stable and its efficiency decreases with time.So the solution must be prepared only when necessary in order to use the wholequantity prepared and avoid waste.

The POLYMAN line has been designed to offer a complete system for manualpreparation of polyelectrolyte solutions and is the ideal choice for occasional ordiscontinuous use.

POLYMAN systems are available in 1000 liters,and generally consist of:
1.Tanks in translucent high density polyethylene,UV stabilized,working temperatures -40 +60°C,built-in level gauge
2.Inspection cover with vent Ø 155 mm.
3.Disperser and water inlet in PVC
4.Powder loading filler in PVC
5.Slow agitator with shaft and rotor inAISI 316 stainless steel
6.Dosing pump (on request)

POWDER FEEDERS

Powder volumetric feeders are designed to provide a constant and accurate flow for any material grain,fibers and powders.Powder feeders are completely made in stainless steel SS304.
