COUNTERCURRENT COOLER

In the area of pellet cooling, a countercurrent cooler is the solution with the best price / quality ratio. By means of a rotary distributor, the granules are uniformly cooled in the refrigerating chamber. The incoming cold air turns the pellet, which gradually cools from bottom to top, so the cooling time increases. The La Meccanica counterflow cooler is equipped with: a condensate trap driven by a 1.1 kW-21 rpm geared motor with brake and limit switch, variable discharge speed through the front flywheel, stainless steel rotary valve, reinforced sheet steel walls, inspection door made of robust glass, fixed and adjustable product dispenser, two rotating sensors, pneumatic closing in case of power failure.

    • lattice unloader It is driven by a 1.1 kW -21 rpm self-stopping motor equipped with a switch. The unloading speed is adjusted with a handwheel. Standard grate: 3-10 mm pellets, maximum length 30 mm. Pneumatic cleaning included
    • rotary valve 350 stainless steel with motor 0.75 kW -28 rpm gear motor
    • walls and extractor: stainless steel with external reinforcements of regular steel; tempered glass inspection door with door switch.
    • Product dispenser: stationary type, manually adjustable
    • two product sensors: swivel with holder for adjustment
    • bunker: with central unloading, 250 x 250 mm
    • surface treatment: spray painted with one thick coat of RAL 1015 paint
    • pneumatic unloader closes when there is no power supply.

Optional

The rollers are adjusted by a hydraulic piston driven by a hydraulic device located outside the machine and controlled from the control panel.

The position of the rollers is calculated by means of an angular potentiometer mounted behind the rollers (inside the main shaft). The potentiometer signals the angular position of the roller pins. By operating the entire system from the control panel, the distance between the rollers and the die can be calculated using the signal transmitted by the potentiometer.

At the electronic panel, the operator chooses the roller position. The panel pressurizes the hydraulic circuit and moves the piston until the rollers reach the desired position.

From the electrical panel, the operator determines the position of the rollers by applying pressure to the hydraulic system and moving the piston until the rollers reach the desired position. Once the desired position has been reached, the system is locked and held in position by two valves.

The maximum pressure reached by the hydraulic system is 250 bar, and the required pressure for moving the piston and adjusting the rollers is 150 bar.

The adjustment is done quite quickly: you can move the rollers closer or further away from the matrix by 7-8 mm, in each direction in about 15 seconds.

The device allows replacing the matrix in 10-20 minutes, depending on its size. The system includes a tapered stainless steel ring that is closed and held in place by Belleville disc springs.

This ring locks the die in place. The matrix is released by pressure on the hydraulic system, which pushes the springs to release the elastic ring.

The system consists of a hand pump and a piston, which are needed to dismantle the die.

The piston is installed between the rotor and the reinforcement flange so as to push the die out of its seat.

This system includes a high viscosity grease pump.

It is equipped with blades to break up possible air bubbles. The system is connected to the press via a rotary distributor connected directly to the main shaft.

Lubrication is controlled by an electrical panel that is included in the delivery. The panel allows you to measure the required amount of grease using two timers to regulate the time for applying grease and pause.

 

The pump has the following characteristics:

● the flow is adjustable from 2.9 to 17 cc / min.

● motor 0.185 kW, 400V, 50Hz

● steel tank for 10 kg

● filter

● pressure relief valve

● pressure gauge

● indicator of minimum lubricant level

● progressive dispenser for distributing grease at two points

● inductive PNP sensor for cycle monitoring

● control valves for 1/8 outlet
