In cleaning, it is necessary to release the adhesion of the impurities to the fibers and to give to particles an opportunity to separate from the stock.

Dirt, dust, foreign matter, and nepsshould be eliminated.

Owing to machine harvesting, cotton contains more and more impurities, which furthermore are shattered by hard ginning.

The available possibilities for cleaning

natural fibers can be divided broadly three

method.

Chemical cleaning.

Wet cleaning.

Mechanical cleaning.

RN Cleaner is a part of Trützschler machine.

It is a zone-4 (fine cleaning) machine.

In contrast to the zone-2 machines, those of zone-4 must again produce new surfaces, i.e. the cleaning operation must be preceded by opening.

Zone-4 machines therefore almost always operate with clamp feeds.

RN CLEANER

Also, the spacing of the striker elements on the rollers must be finer.

Bladed rollers are generally used, the well-known horizontal cleaner, fitted with rollers instead of drums.

Trützschler cleaner is presented here as a representative of all other cleaners.

To open & clear the

cotton by

combinations of the

beating action.

To remove the

impurities such as

leaves, stalk, motes &

sand without damage

the fiber.

Make the cotton tuft

as much as possible.

Feed roller

Beater

Grid bar

Baffle plate

Feed of material to opening rollers occurs in free flight or clamped condition.

Feed devices can be distinguished according to whether they comprised: a feed roller and a feed

table

A feed roller and pedals

Here in RN cleaner, two feed roller with one spiked roller in feed position.

Feeding the material

in RN cleaner

Uniformly follow the

material

Automatically stop

feed roller by sensor

when reserve tank is

full.

An instrument or device used for beating material

There are so many types of beater used in blow room line. Such as: Pinned beater

Saw toothed beater

Kirschner beater

Multi Type balededbeater

Opening the fiber

Cleaning the fiber

Remove impurities

Remove seeds from

cotton

It is the grid or grid-like structure under the opening assembly that determines the level of waste and its composition in terms of impurities and good fiber.

Adjustments of the grid bar Closed (a)

Open (b)

Aggressive (c)

Glancing (b)

Helps to remove

impurities

automatically

Removing waste

from good fibers

Removing short fiber

from long fiber or

good fiber

Baffle plate (a) is a device which is made of metal that typically rests on the inside of cylinder of beater arrangement.

It is slightly curved shape.

Arrangement: One baffle plate for one beater and placed opposite side of grid bar in RN cleaner.

Controlling the flow

path of material

To block the back

flow of material

To improve the

beater performance

To increase the

cleaning efficiency

This is the zone-4 machine of blow room

line.

It is a good instrument of opening &

cleaning of cotton by the action of

beater.

It also removes ascertain a out of

leaves, stalk & other impurities.
