Large Industrial Brushes: Uses, 4 Types and Buying Guide

Introduction: choose the right industrial brush and raise production efficiency by 30%

Did you know? One well-chosen conveyor belt cleaning brush can cut production line stoppages by 50%.

Many factory managers have had this experience: dust and debris build up on the conveyor belt, which leads to unstable product quality, faster machine wear and even production interruptions. Traditional manual cleaning is not only time-consuming but also cannot clean continuously.

This is where choosing the right industrial-grade large brush becomes essential. Whether it is dust removal on a conveyor belt, maintenance of machinery, cleaning large floor areas or maintaining boiler tubes, different applications need different brush materials and designs.

This article covers the definition of large brushes, their material classes, industrial applications, buying criteria and maintenance advice, to help you find the most suitable industrial cleaning solution.

Definition and classification of large brushes

What is a large brush?

A large brush usually means an industrial-grade brush with a brush face larger than 20 cm × 10 cm, or an overall length of more than 50 cm. Brushes of this kind are mainly used for cleaning large areas, removing dust from industrial equipment, or in automated mechanical cleaning systems.

Industrial applications of large brushes

Conveyor belt cleaning brushes

This is the most widespread industrial application of large brushes.

Why is a conveyor belt brush needed?

The problem:

• Dust and debris build up on the conveyor belt
• Product quality is affected
• Equipment wears faster
• Production is interrupted

The solution: Install a roller brush to clean the surface of the conveyor belt continuously.

Types of conveyor belt brush:

Single roller brush:

• Suited to light dust removal
• Simple to install
• Lower cost

Double roller brush:

• Cleans better
• One above and one below, gripping the conveyor belt
• Suited to heavy contamination

Spiral brush:

• The filament is arranged in a spiral
• It guides dust to both sides
• Suited to wide conveyor belts

Choice of material:

• Nylon filament: general dust removal (the most common)
• Steel wire: removing adhered material
• PP filament: the food industry (food-grade compliant)

Specifications:

• Filament diameter: 0.3-0.8 mm
• Roller diameter: 50-300 mm
• Length: custom made to the width of the conveyor belt (up to 3 meters)

Case: After a food processing plant installed nylon conveyor belt brushes, the product contamination rate fell from 5% to 0.5%, saving NT$500,000 a year in cleaning labor costs.

Organic solvents:

• Steel wire, brass wire
• Avoid plastic materials

How do you choose a brush manufacturer with professional knowledge of materials? We suggest reading The complete guide to choosing a brush factory to learn the 5 criteria for assessing a manufacturer.

Choose the stiffness by what is being cleaned

The stiffness of the brush must match what is being cleaned.

What is being cleaned:

Precision surfaces (optical lenses, precision instruments):

• Choose very soft filament: horsehair, goat hair, soft nylon (0.1 mm)
• Avoid scratching

General surfaces (conveyor belts, equipment housings):

• Choose medium stiffness: nylon (0.3-0.5 mm), PP
• Both cleaning power and gentleness

Rough surfaces (floors, walls):

• Choose stiff materials: stiff nylon (0.8 mm or more), steel wire
• Removes stubborn stains

Degree of soiling:

Light soiling (dust, paper scraps):

• Soft filament is enough
• Avoid over-cleaning, which wears the surface

Medium soiling (oil stains, dirt):

• Medium-stiff filament
• Use with a cleaning agent

Heavy soiling (carbon deposits, corrosion):

• A stiff wire brush
• A rotary type may be needed for more cleaning power

Choose the specification by the equipment

The specification of a large brush has to match the equipment.

Conveyor belt brushes:

Width:

• Chosen by the width of the conveyor belt
• Usually 5-10 cm wider than the belt
• Ensures full coverage

Diameter:

• Roller diameter 50-300 mm
• The larger the diameter, the larger the cleaning area
• But the installation space has to be considered

Installation method:

• Shaft type (mounted through the bore)
• Flange type (fixed at both ends)
• Confirm the interface on the equipment

Tube cleaning brushes:

Brush head diameter:

• 10-20% smaller than the inner diameter of the tube
• Too large and it cannot get in
• Too small and it does not reach the tube wall

Handle length:

• Chosen by the depth of the tube
• Leave room to operate

Floor cleaning brushes:

Brush face width:

• Hand-pushed: 50-80 cm (too wide is hard to push)
• Mechanical: can be 100 cm or more

Filament length:

• General floors: 30-50 mm
• Rough floors: 50-80 mm

FAQ

1. How do I choose where to install a conveyor belt brush?

The installation position affects the cleaning result. Consider the following factors.

Choosing the installation position:

Above the conveyor belt (the most common):

• Cleans the carrying side of the belt
• Removes debris dropped by the product
• Prevents contamination of the next batch of product

Below the conveyor belt:

• Cleans the underside of the belt
• Prevents dust from building up
• Extends the life of the belt

At both sides of the conveyor belt:

• Cleans the edges of the belt
• Prevents dust from piling up on the rollers

Installation angle:

• A contact angle of 30-45 degrees between the filament and the belt is recommended
• Too small an angle gives too little cleaning power
• Too large an angle damages the filament easily

Pressure adjustment:

• The filament only needs to press lightly on the belt
• Avoid excessive pressure, which causes wear
• An adjustable bracket allows fine adjustment of the pressure
