In many process industries there are applications that are specifically engineered for the job they perform. Using a machine that performs exactly the required job can allow for more efficient product treatment, lower process time, and longer machine life. With this in mind, it is important to consider the robust variety of industrial dryer types, as well as the options that dryers can have. In many process operations there is more than one process required. This is where dryers with other operations can excel. Performing both of these processes at once saves time and floor real estate, as there is only one machine required. There are multiple examples of combined process dryers including separation (screening), cleaning, cooling, granulation, and crushing.

Screening is often done as its own process step requiring multiple decks of separation, prior drying and sorting, as well as other requirements. For certain solutions however, there are dryers that can screen up to one separation. This reduces need for further screening down the line in some operations, or even just reduces the amount of separations needed by performing it while drying. These dryers are useful for aluminum scrap and shredded recyclable products. The need to screen after drying is a common problem and alleviating this step can save energy and time. The process works like any regular rotating drum, however the outside of the drum is perforated to let material through. Smaller particles fall through the drum and are separated as they would be in a screener. In certain plants where only one separation is needed, these dryers allow for the removal of a screener. In others where multiple separations are needed money can be saved due to one separation being performed during the drying step.

Dryers are often used when recycling glass and processing stone such as limestone. The issues that arise in these processes are often unwanted particulates or material finding their way into the process flow and compromising the product or causing costly damage to machines further down the line. In the case of recycled glass this would be left over labels or in the case of stone, dirt and other particles. This is where a dryer with cleaning capabilities would be a great fit, saving time and money where separate process and machine would otherwise be needed. The processes for these machines are similar. First the product is dried in a rotating drum. Then the paddles inside of the drum pick up and move the product into the drying air flow. This causes the product to dry and rub against each other. These combined forces remove the unwanted particulates, which are then removed from the machine through the exhaust. Clean product then continues through the process flow. As with all examples of combined dryers, the energy, time, and maintenance saved make this a great solution to your process.
