Getting ready for the grinder season: Colourizer Tips
As spring approaches and temperatures begin to warm up again, many companies that convert wood waste into valuable mulch are both excited and eager to thaw out their grinding and colourizing equipment and get started as quickly as possible.
Before the work begins though, taking a few preventative steps to ensure equipment is prepared for the season will provide the best opportunity for success and profitable results.
First, be sure to thoroughly clean all colourizer lines. This can be done by simply running water through the lines to ensure any dirt, debris or containments are cleared out.
Next, inspect injection lines at the top of the grinding chamber to make sure they are not restricted. Even a small amount of buildup in this area should be cleaned and removed to ensure the process is as efficient as possible.
Check the water supply and the water lines. Make sure they are clear, clean and that all connections are fitted correctly. Also check the colour pump lubricant level to ensure a sufficient amount is present in the pump.
Finally, be sure to test the colourizer system before starting, especially if you're starting the colour pump for the first time after the winter. Testing can be done by simply running a five-gallon bucket of water through the system to ensure all components are working properly.
As mulch producers navigate through the spring months when weather can continue to be unpredictable, and especially as temperatures can dip back below freezing, a few additional helpful tips are listed below.
If you are operating in temperatures that are below freezing, it is important to drain the colourizer system after use to prevent any liquids from freezing within the colourizer or water lines in the system.
Also, do not use frozen colourant. Using frozen colourant can lead to unequally mixed colours and damage and obstructions to the colourizer lines.
Lastly, be sure you are utilizing the correct screen sizes. If the feedstock you are using is wet, utilizing larger screens will prevent clogging up the machine and slowing down the process.
If, after following these steps, something is not working property or your output is not providing the results you need, contact your equipment's customer support team to assist with any questions.

The Eddy Current Separator (ECS) is one of the most important pieces of equipment in a recycling operation. For operators of MRFs, auto-shredders or e-scrap facilities, it's usually one of the biggest revenue generators. Keeping the ECS running is important to the recycler's bottom line, therefore it is essential to reduce unexpected downtime.

Long before a single load is booked or any wheels turn, someone - usually a fleet manager - needs to determine exactly what is going to separate the road and the load. There's a lot riding on this decision because, as much as some would like to think otherwise, a trailer is never just a trailer. It can be manufactured to many different specifications, with multiple raw material options, dozens of load and geographical considerations, various top speed requirements and hundreds of possible axle configurations coming into play. And it all comes down to one objective - the ideal trailer for an operation's specific loads.
Bridgestone Americas, Inc. has announced the expansion of its off-the-road (OTR) product portfolio to include a new size of the Bridgestone VSMS2 tire. The tire is now available in size 29.5R25 in the U.S. and Canada.

Pegnitz, Germany - Recently, BEKAWORLD held a groundbreaking ceremony for a new plant in Wannberg, Germany.
Approximately twenty years ago, those of us working in the off-road heavy equipment industry regularly witnessed a high amount of failures in machines operating on cement or other hard surfaces. Extended steel rims were used with small, hard, rubber wheels. When these rubber tires chipped and chunked, vibrations and bouncing sent shockwaves into the machine, causing shortened life and expensive repairs, not to mention stress on operators. Drivetrain components (U-joints and articulation joints) in particular often suffered from stress cracks caused by vibrations and a bouncing machine.
The forklift fork is often overlooked and under-inspected. Many are unaware of how often one should inspect their forks, and how to inspect them. Federal law (OSHA Standards 29 CFR 1910.178) mandates that forklift forks which see around-the-clock use should be inspected on a per-operation basis. As part of a pre-operation inspection, forklift forks should ideally be inspected for signs of cracks, bends, excessive wear or damage to either the fork tine or the positioning lock when using an ITA mounted fork.
As one of the leading Off-Highway tire manufacturers worldwide, BKT has been able to find solutions even for the most demanding and toughest operating conditions in recycling applications by means of specially designed products for loaders and material-handling machinery. This sector and any related application areas appear to be fairly interesting in terms of tires that are subject to severe strain. Not only do they have to meet the requirements as far as resistance and durability are concerned, but they must also offer stability to the equipment and thus a certain level of comfort to the operator.

According to a recent survey of Independent Equipment Dealers Association (IEDA) members, the EPA’s Tier 4 mandates are driving up the demand of non-Tier 4, used construction equipment and predicts this trend will continue for the next several years. For many equipment categories, used equipment availability is outpacing demand, but for other categories, including excavators, backhoe loaders, wheel loaders, dump trucks dozers and compact equipment, IEDA members are seeing resale pricing increase by as much as 20 percent. Also, more than 50 percent of survey respondents noted that quality used equipment is getting harder to find.
Fuel quality is critical to keep Tier 4 engines running smoothly, and the Association of Equipment Manufacturers (AEM) has released a downloadable infographic to help equipment owners and users keep their machines up and running.
