Marzoli has always been attentive to the development and design of blow room machines, because an effective opening, cleaning and mixing are the guarantee of the final product quality. Furthermore, proper fiber preparation positively affects production and quality performance of carding, combing and spinning processes.
The choice of the opening machine is a strategic one for the whole production, like the carding and spinning machines.
Even with the Nova line introduced in 2004, all Marzoli opening machines have changed considerably both in terms of production and quality. The beaters with multiple speeds and various combinations of tips, different choices of grids, carding segments, knives and flaps had improved the selection of fibers and consequently the cleaning quality.
The new opening line Galileo pre
sented at ITMA in Barcelona has kept the same line, but introduces new opening and blending concepts that have improved the selection of fibres. This has allowed significant improvements in terms of increasing the cleaning, opening, mixing and waste reduction.
The new working width of 1,600 mm allows to reach a production level of 1,000 kg/h on a single line or 1,600 kg/h with a single line with two fine openers and always with excellent quality results.
The key machines of the new Galileo line are the horizontal opener Duoclenaer B390L and the fine opener Duo Blended Cleaner B380L. Both machines have very innovative ideas for what concerns the treatment of fibers and, with the results being tested and confirmed by several spinning, are gaining a decisive role in the new spinning mills.
In the new Duocleaner B390L the fibers inside the machine turn four times around the first semi-beater with a spiraling d
irection and four times around the second one, for a total of 16 times in the entire machine. No other opener on the market today is able to offer in-depth and selective cleaning.
The different speed of the two beaters, combined with the different configuration and population of the tips, allows to get a progressive and effective opening and cleaning, without fiber breakage.
The different grids with independent settings are easily adaptable to any type of cotton with excellent results on waste reduction.
Several tests in different spinning and with different types of cotton have confirmed a 40-60 per cent trash removal depending on the type of fiber worked. The special configuration of the beaters and the flow of the material around them is covered by Marzoli patent.
The feeding of cotton to the B390L is carried out by the new cage condenser B450L that, thanks to the suction on both sides and to the new increased working width, has allowed a very significant increase of the de-dusting of the material.
The new Duoblended cleaner B380L, thanks to the double feed chambers with air pressure, doubles the mixing of the opening line, with considerable benefits for the homogeneity of the final product.
In the traditional opener, with the table and the feeding roller, the material is clamped and delivered to the opening beater with a very strong acceleration which can damage the fiber. In the new B380L there isn’t the traditional feeding table and the material is introduced freely in a pre-chamber where two pre-opening rollers open the fibers and prepare them for the next progressive cleaning action performed by the two sequential beaters with tips.
The two beaters have different tips, different rotation speed and different settings of the flaps and carding segments. The working width of 1.600 mm allows to reach production up to 1.000 kg/h with excellent efficiency of opening and trash removal. The structure and innovative arrangement of the beaters is covered by Marzoli patent.
These innovative concepts of the progressive cleaning of the B380L have allowed to improve the selection of the fibers, optimize the cleaning and increase the degree of opening, mixing and de-dusting of the material while reducing the percentage of waste. The B380L is very flexible and allows to compose lines without the mixer, saving on space and investment. Other features include easy accessibility for cleaning and reduced maintenance costs.
The Galileo blow room line, in addition to the two new openers B390L and B380L, is composed of the Superblender B 12 with two beaters, the high capacity mixer B143L and, of course, with the new card C701.
This new line is confirming to the various customers, the excellent results that have been reached during the long test of the prototypes.
