IMPROVING COLOSSAL GRID OF 5LP LINTING TECHNOLOGY
PROSESSES AND INITIAL IMPROVEMENT

Adjustment of the supply of seed to the linter is performed depending on the
density of the seed mass in the working chamber. The performance of the linter on
the seed is carried out by changing the length of the chain connecting the variator
with the seed density lever in the working chamber and by changing the position of
the load on the lever of the density lever.
Keywords:
Seeds, grate, stirrer, saw shaft, seed comb, air blower.
Introduction
Columns of 5LP linter equipment are made of U8 steel. Lower operating costs
are achieved by installing the improved U13A steel plate shown in the above picture
on the working part of the grate, that is, the working part where the saw disc feeds
the fluff. Also, the installation of the proposed metal plate will save time and
resources (new colostrum) required for replacing spread colostrums, preventing
broken pieces of seed from passing through the fluff due to spreading.
The main task of the linter equipment installed in the linting department of
cotton gins is to separate the fluff from the surface of the seed mechanically, that is,
with saw teeth. Linters are subject to the following requirements: seed and lint
should not be damaged during linting, impurities and impurities should not be added
to the lint, the mechanism (tool-equipment) that controls the quality of lint, the level
of fluffiness of the seed, and the performance of the linter should work.
The main indicators of linter work are the level of fluff separation and the
productivity of the seed.
There are two ways to configure the linter workflow:
- by changing the position of the seed comb;
- by changing the seed supply procedure.

By changing the position of the seed comb, the degree of fluff separation from
the seed is changed. By changing the seeding mode, the linter's seeding performance
is changed.
Adjustment of the supply of seed to the linter is performed depending on the
density of the seed mass in the working chamber. The performance of the linter on
the seed is carried out by changing the length of the chain connecting the variator
with the seed density lever in the working chamber and by changing the position of
the load on the lever of the density lever. The adjustment of the separation of dust
and dirt is done by changing the position of the dust separation rail of the air
chamber.

The linter is equipped with a working chamber lifting mechanism. The
mechanism is controlled by a button on the linter control panel. The kinematic
scheme of the rotary working bodies of the 5LP-linter is shown.
Linter production indicators are characterized by three different indicators:
- Lint separation productivity (kg/hour);
- Productivity of hairy seed transfer (kg/h);
- Lint acquisition percentage (%).
These indicators are interconnected as follows:
R=Q · C/ 100 kg/h
Where: R is linter performance, lint by lint
Q - productivity of seed transfer
S is the degree of lint removal from the seed, in %.

Columns of 5LP linter equipment are made of U8 steel. Lower operating costs
are achieved by installing the improved U13A steel plate shown in the above picture
on the working part of the colosnik, that is, the working part where the saw disc
feeds the fluff. Also, the installation of the proposed metal plate will save time and
resources (new colostrum) required for replacing spread colostrums, preventing
broken pieces of seed from passing through the fluff due to spreading.
The 5 LP linter under development has a linter capacity of 100 kg/h and a seed
capacity of 2000 kg/h. A seed receiver-cleaner (KPP) is installed on the linter.
Seed falling into the working chamber is distributed in the required amount
with the help of the density handle and variator brand IVA-40.
