Brushes for belt conveyors are usually grouped according to where they are mounted. The various types include:
Carry Side Brushes
These brushes are fixed on the carry side of the conveyor belt where product loads are placed. Their main role is to clean the residue left on the belt at the point of product transfer. The carry-side brush helps in preventing cross-contamination of products as well as ensures that the same cleaning standards are maintained throughout the belt. This reduces the accumulation of dirt and debris on the surface of the belt, thus promoting hygiene.
Return Side Brushes
Return side brushes are mounted on the underside of the conveyor belt. These brushes are important as they clean the underside of the belt during transportation back to the loading point. They remove material that may have been trapped on the underside part to ensure that when the belt returns, it is clean and free of debris. This reduces hygiene risk and minimizes wear and tear on machine components.
Impact Area Brushes
The impact area is defined as the section of the conveyor where material first contacts the belt. This is the most critical area when it comes to cleanliness, as it is possible that the conveyors top, bottom, or both sides are brushed. Cleaning brushes should be located in this area so that all materials in the conveyor can be effectively cleaned. These brushes can remove most of the debris, thus enhancing cleansing of the materials that come into contact with the belt.
Edge Brushes
Edge brushes are mounted on the sides of the conveyor and primarily focus on cleaning any build-up that may have accumulated along the conveyor edges. They are important for preventing the accumulation of residue on the edges, which can eventually cause the brush to wear or even result in product contamination. Edge brushes help to ensure that all areas, including the side not commonly in contact with the object, are clean.
Guide Strip Brushes
These are specialized brushes that are mostly installed on the conveyor's guide strips or rollers. They are used to prevent belt misalignment and ensure proper tracking of the system. The bristles brush away any debris that may have accumulated on the strip and hence improves its stability. This further helps in decreasing the frequency of adjustments and repairs.
Belt conveyor brushes are widely used in various industries to maintain conveyor belts’ cleanliness. The major applications include:
Food and Beverage Industry
The food industry uses belt conveyor brushes for the hygiene maintenance of their conveyors frequently. The importance of cleanliness is greater here, and brushes are used to eliminate dirt and bacteria from the belt surfaces prior to product transport. This is done to avoid cross-contamination at a the bare minimum and to maintain a clean environment. Moreover, the food processing sector uses these brushes in prevention of accumulation of food residues on the belt which may lead to spoilage over time.
Mining and Minerals Industry
Mining and mineral processing industry heavily depend on conveyor systems for transport of bulk materials like ores and minerals. In this industry, the brush’s main purpose is to clean the conveyor· belt before transporting materials. This cuts down on transfer of dust or any particles from previous conveyed materials to the current one. Besides, brushing also prevents the accumulation of mineral residue on the conveyor, thus prolonging belt life in the process.
Packaging Industry
Conveyor brushes are essential in the packaging industry for keeping their conveyor systems’ clean. This will help to eliminate any residue, labeling debris, or spills that may hinder efficiency. Moreover, maintaining proper cleanliness of the belt using brushes help to eliminate contamination of packaged products. This helps improve overall product quality and hence makes it to have a better shelf life.
Pharmaceutical Industry
Hygiene is a crucial element of any conveyor system's functionality within the pharmaceuticals arena. Conveyor brushes in this area eliminate all kinds of traces of drugs, chemicals, or germs that may have been left behind. This ensures that the belt is clean and safe for transporting drugs, medical equipment, or supplies. It also aids in complying with safety regulations within the industry to avoid contamination.
Agriculture and Feed Industry
Belt conveyor brushes are used in agricultural and animal feed industries to maintain inventory systems like grain, seeds, and feed. The brushes prevent cross-contamination by eliminating residues associated with transported products. They also improve the efficiency of the conveyers by preventing accumulation of large debris that could affect operations.
Belt conveyor brushes come with various special features that enhance their performance. These include:
Material Durability
The materials that are mounted on the conveyor belts are durable enough to work long hour and withstand constant wear and tear. They are often made of metal or stiff plastics. This ensures that the brushes are hard wearing and will not wear out with daily use.
Flexibility
Brushes with flexible bristles easily reach and clean the equipment's complex surfaces. These are vital for cleaning the edge or corner of the belt as well as other hard-to-reach places. Flexibility also enables it to adapt to different surface types for effective cleaning wherever they are fixed.
Mounting Options
This feature varies depending on the type of brush; in other words, if it is carry side, return side, edge, or impact area brush. Varying mounting options ensure that every brush can be properly and practically integrated into existing conveyor systems. This means that each brush is fixed in a way that provides maximum efficiency in cleaning the conveyor belt.
Customizable Brush Pressure
This is another interesting feature; for instance, conveyor belt brush systems allow adjustable pressure. One can increase or decrease the pressure at which the brush contacts the belt. This feature enables users to have an option depending on the type of material on the belt and the amount of mess.
Resistance to Chemicals
Most commercial grade conveyor belt brushes are resistant to chemical and temperature extremes. It may be necessary to have a time-saving and effective clean-up using chemical substances or face the risk of damage to the brush. Likewise, operating in an extreme environment's heat or cold, durability remains intact.
Low Maintenance Requirements
Automated guides and low-maintenance components mean that the brush roller systems require little to no upkeep. Systems that allow autonomous operations increase time efficiency by eliminating the need for frequent manual inspections or brush replacements. This means they are provided with long working hours without strain for the brush conveyors.
Size and Shape
The brush size and shape used on belted conveyors is one of the great factors to consider. Choose the ideal brush length according to the width of the conveyor in question. Decide on the shape circular brushes for rollers and belts, while flat brushes are better on straight sections.
Material
The durability of the belt-driven brush depends on the material that it is made of. Nylon is flexible and wear-resistant, making it ideal for medium tasks. Polyester, on the other hand, is highly resistant to various chemicals, making it ideal in environments with high chemical concentration.
Application Conditions
Application conditions refer to the types of load or materials that one might convey. Soft brushes made of flexible material are advised when conveying sensitive items such as food. Stiffer material should be used for large debris and heavier loads.
Mounting Options
Mounting options should be adaptable to existing systems. Some brushes may require in-depth alterations to the promised solitude, while some will slide in with no problem at all. Aim for one that will need little to no modification to the prevailing conveyor systems.
Customizable Brush Pressure
There are several key elements here. Those that have brush pressure adjustment give the user more flexibility. An additional or less pressure can enable one to adjust depending on load or mess; it is a very important function.
Ease of Maintenance
Maintenance requirements will vary from one brush system to another. As mentioned above, low-maintenance self-wearing brands and materials will work well since this is one of the factors. In this case, convenience will take preference since the users do not wish to have a lot of work on their hands.
