Coating drums continue to receive attention as a way to meet the requirements of specialty products in industries using granular bulk solids; by adding a drum coating machineto an existing organic fertilizer production line, producers can improve their control over handling characteristics, product performance, even the ability to modify the chemical composition or formulation of a material.
1. Process development capability of coating machine
Coating drum operation is usually simple and usually does not require extensive development work to obtain an effective machine. However, when efficiency, product quality or specific processing conditions become a priority, process development capability is critical to project success.
Again, depending on project requirements, a high degree of customization in the design may be required. This is typical in roof granule coatings, as the effectiveness and longevity of asphalt shingles depends largely on whether the granules are consistently applied to specification. Producers looking to purchase coating rollers should be aware that not all coating roller manufacturers offer custom solutions; many offer standardized units and select the unit that best suits a given application.
3. Mature experience
As with any capital investment, buying from a reputable supplier can save you a lot of hassle and expense in the long run. Look for vendors who can demonstrate past success through program profiles, testimonials, and references.
4. Parts and Service Support
Choose a supplier with a strong parts and service program for aftermarket support. This may include assistance with start-up and commissioning, provision of spare parts, routine maintenance, annual inspections and process audits.
5. High quality standard
Coating drums are a major investment, so the life of the coating drum is important. Several factors can affect the quality and life of a coated drum, including materials of construction, welding techniques, manufacturing practices, and more.
