Roller conveyors are machines that are made from mostly steel and stainless steel that use powered or non-powered conveyor rollers to move the loads of goods or products from one place to another. Roller conveyors help to move items without causing any damage. They are being used in warehouses, factories, and other businesses.

1-A. What is a Conveyor Roller
A conveyor roller is a key component in many conveyor systems. As its name suggests, it is a roller that helps to move items along the conveyor belt. Conveyor rollers are usually made from strong and durable materials such as steel, making them ideal for high-traffic areas.
In its simplest form, a roller consists of a steel tube, a shaft, and ball bearings. They are also often coated with a low-friction material, which helps to keep the conveyor belt moving smoothly.
In some cases, conveyor rollers may also be equipped with additional features such as motors, as is the case with MDR conveyors. These additional features can help to improve the efficiency of the conveyor system.
1-B. What is an MDR Conveyor Roller
MDR stands for motor-driven roller, and these rollers are driven by an electric motor. MDR conveyor rollers are used in various applications, including package handling, assembly line manufacturing, and warehouse automation. MDR conveyor rollers are available in various sizes and styles to suit the needs of any application.
MDR conveyor rollers are typically used in accumulation and high-speed sortation conveyor systems but can also be used in other types of conveying systems, such as gravity conveyors. MDR conveyor rollers are more expensive than conventional idler rollers, but they offer several advantages, including higher capacity, longer life, and better reliability. They also offer a much higher ROI as compared to other types of conveyors. Energy savings alone could be worth the switch to some.

When planning a bulk materials handling operation, choosing the right machine to do each job is very important. Machinery has evolved into extremely efficient &#;tools of the trade&#; since the pick and shovel. Unfortunately, the mindset of many managers for choosing a belt cleaning system is still in the days of the pick and shovel, Today, belt cleaners are engineered machines, each carefully designed to do a specific task.

Installed on the face of the head pulley below the material trajectory, a primary or pre-cleaner uses a urethane blade to remove the overburden of material from the belt.
Secondary cleaners are installed to remove fines and sticky clays at the point where the belt leaves the head pulley or along the return. Shock absorption is built into the cleaner or tensioning device, allowing metal belt splices to pass without damage.
Tertiary or final cleaners should clean grooves, cracks and abrasions in the belt cover while removing water.
The criteria to choose a belt cleaning system should be as carefully developed as the considerations for selecting a continuous miner, roof bolter or underground equipment.
The first thing to consider is the operation&#;s goals for the cleaning system. Do you want a belt that won&#;t drop &#;too much&#; material, or do you need a belt that is &#;white glove&#; clean. Are you trying to keep regulatory agencies &#; EPA, OSHA, MSHA, State DEQ or neighbors &#; happy? Or is your goal to reduce cleanup labor and improve idler life? And most important: given the realities of maintenance budgets and staffing, what level of cleaning are you willing to accept?
It is best to know &#; and spell out &#; in advance what the goals are for the performance of a cleaning system.
Next, the conveyor itself must be considered. You must note the &#;measurables&#; for the conveyor, including:
These specifications establish a &#;duty range&#; for the cleaning system &#; medium, heavy or extra heavy-duty.
The next criteria that must be considered are the characteristics of the material, including:
When specifying a belt cleaner it is best to consider the material in its worst state. That way, the cleaning system will be prepared for adverse conditions when they inevitably occur.
Finally, the issue of cost must be considered. Too often, price is the first criteria to be evaluated when purchasing a component. It is better to place this issue at the end of the selection process.
