What is step cleaner in textile?
In the textile industry, a step cleaner is a common machine used in a blower room. It is used to open and clean by opposite spike action, remove heavy impurities, and make smaller tuff cotton.
A step cleaner, ultra cleaner, or super cleaner machine is one of the most important machines used in the blowroom section of the spinning industry. This major beating type of machine is used for opening and cleaning the impurities from the cotton tuft.

Working principle:
Cotton is fed from the reserve tower by a pair of feed rollers. Later it passes to the first beater. From there it is transported upwards by the six (sometimes 4) beater rollers, each carrying profiled bars, the beaters arranged on a line inclined upwards at 450. As you can see in the diagram.
The step cleaner machine diagram is as follows:
The trashes are extracted with the help of opposite spikes and beating functions. It pulls the trash and falls into the chamber through the grid bars hole. Cotton tuft opens and makes small-size tuft with beating action. A baffle plate is in the middle of two beaters, and it controls the flow of material.
Elimination of impurities occurs during the continual passage of the material over the girds arranged under the
beaters. The grids are continuously adjustable and usually also the beater speed.
How to increase beating action in step cleaner?
– By increasing the beater speed
– Increase grid bar
– Increase grid bar angle -150 (Max), 00, – 150
