Sustainability is increasingly important in everything from manufacturing to construction practices. The materials that are used in construction are now also scrutinized for their environmental impacts and sustainable manufacturing practices. In light of a push for sustainability, concrete recycling has become more common since the 1980s....

Screen mesh blinding occurs when fines become stuck inside the holes of the screen media. Blinding of mesh prevents other fines from passing through the screen. As a result, efficiency is limited, production is reduced, and time will be needed to clean or replace the...

Aggregates — such as gravel, sand, or crushed stone — are among the world’s most important building materials. Roughly 60-75% of concrete is comprised of aggregates, and aggregates make up around 90% of paving asphalt. To create strong, stable construction materials, the aggregate used must...

Flip-flow screens, also known as flip flop or elastic mesh screens, are machines designed to efficiently screen sticky, wet, and other difficult materials. Flip-flow screens are used in a number of industries to separate everything from aggregate and minerals to inhomogeneous recyclables, construction waste, and...

Sand is an important construction aggregate used in the production of concrete mixes. However, before it can be used for concrete and cement production, sand must meet specific grain size and cleanliness requirements. As concrete mix specifications change, so too must the aggregate used in...

Vibratory screens are one of the main types of industrial screening equipment. There are several mechanical screening solutions available across the solid waste management, recycling, and aggregate industries; however, vibrating screens offer a number of unique advantages that make them a first-line option for a...

Since the inception of single stream recycling, there has been a back-and-forth debate on which process is better: single or dual stream. This has been a persistent issue for MRFs, haulers, and municipalities alike. The debate has centered on which collection method provides the safest,...

Material Recovery Facilities (MRFs) play a vital role in waste management, scrap processing, and the recycling industry. MRFs specialize in separating, sorting, and ultimately preparing recovered materials for sale to an end buyer. However, increasingly strict international regulations have made recycling contamination a growing concern for...

There are a number of available material screening solutions. Material specifications will dictate the type of screening equipment that is most efficient for the given process. Trommels are one of the most commonly deployed screens for a number of jobs - from compost to municipal...
Read More In Part 1 of our discussion on manufactured sand (mansand) we talked about the Ortner® Sand Washer and its ability to remove unwanted fines from screenings while using very little water. But what if washing is not an option, due to: No water available Cost...
