Round design to avoid bridging of difficult flowing materials.

Continuous and metered discharge of the material out of the storage silo into a discharge screw by a discharge scraper The compactor feeding screw is continuously adjustable and conveys the material through the center of the stator disc into the working zone. Both screws are controlled via frequency converters.

The silo is equipped with level indicators and a maintenance door with inspection window.

Advantage: Different bulk densities don’t require adjustment / replacement of the conveying screw.

For maintenance purposes the compactor feeding screw mounted on slide bars can be moved manually thus ensuring an optimum access to the compactor discs.

DISK TYPE AGGLOMERATOR

The silo discharge, the screw feeding device and the compacting unit are one process system.

The feeding screw force feeds the material controlled by the current consumption of the compacting unit into the compacting discs. The compacting takes place in the compactor unit between the rotary and stationary compacting discs.

The gap between the discs is automatically adjusted during operation.

For opening the compactor housing. The feeding screw is moved manually to the back. This allows excellent access for cleaning and maintenance work.

Drive oil circulation: approx. 0,18 kW

Drive disc adjustment: approx. 1,5 kW

Support:

Profile steel with belt-guard and motor rails.

1 Conveying system

Connecting pipework from compactor to the central blower

15 kW, connecting pipework to the cyclone separator II with feed hopper to the granulator. Exhaust air to be conveyed to the outside.

Common base frame for compactor, drive and feeding device Advantage: no need for a separate isolated foundation

HOT MELT GRANULATOR

Cutting chamber opening: approx. 780 x 980 mm

Rotor diameter: 600 mm

Rotor length: 980 mm

Rotor knives: 7x2

Stator knives: 2x1

Knife quality:

All knives are manufactured from high quality chrome nickel tool steel.

Cutting geometry:

Double cross cutting action, i.e. the rotor knives are mounted at the same inclined angle but opposed to each other.

Knife adjustment:

this is carried out outside of the granulator in a jig supplied with the machine.

Rotor bearings:

self aligning roller bearings in steel pillow blocks completely outside and separate from the grinding chamber. Closed design with permanent lubrication.

Housing design:

centrally hinged two piece welded steel design - upper and lower housing units meet at an inclined angle. Both bed knives are mounted to opposite sides of the dividing surface.

Consisting of:

Material infeed via rotary valve, approx. 1,1 kW, feed back of fines into the silo via rotary valve, approx. 1,1 kW

connecting pipework, fines separator and cooling unit designed as zig zag channel; in counter direction to the flow of the agglomerate, an air stream is sucked through the zig zag channel to take out the fines and for cooling the material. Including blower approx. 7,5 kW, 45 m³ air/min. The fines are returned to the storage silo.

Material Transport System with BigBag Station

Conveying system for big bag filling,

material blower with 11 kW drive motor,

connecting pipework, a cyclone separator with mounting frame, complete with twin big bag filling nozzles and an extract air hood with hanging filter bags.

Full level indicator and electro-pneumatic diverter valve

OPTION

1 full level indicator for each big bag (With optical or soiund alarm when message “full big bag” is issued)

1 electro-pneumatic diverter valve

The full level indicator detects when the big bag is full and transmits an electrical signal via the control cabinet to the diverter valve which then automatically switches over to the empty big bag. At the same time, a signal (option: optically or acoustically) is released which alerts the operating personnel. If the big bag is not exchanged after a time to be determined (in the control cabinet) and confirmed, the plant closes down automatically beginning at the front.

Service platform

Small service platform for easy hook in of big bags,

Recommendable for big bags higher than 1800 mm,

2 service platforms on 2 sides of the big bag station.

(Optional 3rd platform on the back side)

Electrical control with PLC control type S7-1500

The control cabinet contains all necessary protection devices, relays and fuses to operate the complete system.

Visualization with Siemens Touch Panel HMI 7“.

All drives can be controlled from the touch panel. Additional HMI units can be supplied against surcharge.

Operating conditions including motor failures are represented by symbols.

The operating mode is pre-selected via the touch panel.

1. Manual - Automatic operation / 2. Service mode

Manual: The drives can only be switched on successively according to the enabling sequence. When switching off, successive drives of the quoted plant are also switched off.

Automatic: The drives of the plant are switched on / off successively dependent on time and according to the enabling sequence.

Service: All drives can be switched on / off at will without enabling sequence.

A load interrupter switch (main switch) separates e. g. for maintenance work the plant from the network supply.

Control voltage for field devices (actuators and sensors) is 24V DC.

The compacting process is fully automatically controlled including automatic adjustment of the feeding device and the gap between the discs.

Recording of the operating parameters of the system (e.g. current, temperature, fill levels, speeds etc.).

The electrical control unit meets the relevant up to date EC directives.
