Raw material deconditioning for masterbatch mixture preparation incorporation extruder line

Processed powder: cobalt, calcium carbonate CaCo3, titanium dioxide TIO2.

Masterbatch and additives.

 

Tunisian specialist in the compounding of engineering plastics offering a wide range of products for the automotive, electrical and electronic, construction and sanitary sectors.

The objective of the installation is to discharge raw materials while maintaining a healthy atmosphere without pollution and without loss of material.

Solution implemented:
CaCO3 and TiO2 preparation unit.
A manual Sacktip® S bag emptying station is installed on a platform. It is fitted with a dust collection system and a bag compactor. The stainless steel containers mounted on wheels are positioned under the platform and are connected to the bag emptying station by a filling head with a telescopic cylinder and a flexible connecting sleeve. The operator manually doses the material into the container by counting the number of bags. Overfilling is avoided by a level sensor in the filling head. Once the high level is reached, the detection flashing light is activated. The same equipment can be used for CaCO3 and TiO2 with a washing operation between the two stages.

Master mixing unit 
The ingredients are lifted up onto the platform using a manual hoist.
The deconditioning of raw materials is carried out on the first floor. 
All additives are metered on the laboratory balance below the suction booth. The materials are dosed in masked time during the duration of the previous mixing. Once the pre-weighed materials are introduced into the bag emptying station, the valve is opened and the powder is introduced into the mixer.
CaCO3 and TiO2 are introduced into the industrial mixer in a maximum of 15 minutes. The 1000 and 500L containers are moved manually to the station and the connection is made manually by a flexible sleeve that can be dismantled without tools.

M50 extruder feeding
The M50 extruder is fed either from a container for CaCO3 or from a bottle for master batch. These equipment are lifted on the platform using the existing hoist. The request for CaCO3 is controlled by the level sensor of the hopper D5 in order to open or close the automatic butterfly valve. 

M72 extruder feeding
The CaCO3 is supplied by pneumatic conveying. The storage containers are connected to the VFlow® pneumatic conveying system through a suction pipe. The shared vacuum pump is used to supply the cyclone of the SF1 or SF2 dosing unit according to the signal from the buffer hopper. The master mixes are lifted on the platform using existing hoists. They are connected to existing hoppers with flexible connection sleeves that can be dismantled without tools.
