NDC's New Non-Contact Moisture Analyzer

Irwindale CA -- NDC introduces a new model to its established 710 Series of on-line analyzers for industry. The new CM710 moisture gauge has been developed to provide reliable performance in the harsher industrial operating environments found in the minerals, ceramics, ore processing, chemical, sinter and similar processes.

Mounted 250mm above the product on the conveyor and able to measure over fluctuating product heights, and even discontinuous product flows using the optional High Speed Gating system, the patented non-contacting NIR reflectance (backscatter) optics are designed for best accuracy and maximum long-term stability without ever needing to be recalibrated.

With a range of available housings with sealing ratings up to IP67 for full hose-down areas, as well as ATEX certified options up to Zone 20 dust-hazard, CM710 is designed to operate in ambient temperatures up to 50 degrees C, or hotter with an optional cooling attachment.

The CM710 displays the product moisture content on its full color Operator Interface and measurement outputs are available with a choice of formats, from a scalable analogue output to full network connectivity (Profibus, Modbus Plus, DeviceNet, Ethernet) to enable integration into PLCs and factory DCS or SCADA systems to provide closed-loop control of the drying process.

With mounting fossil fuel prices, industry expends huge resources in drying powdered and mineral products down to target moistures. Introducing closed-loop control based on the stable drift-free output of the CM710 enables users to introduce energy savings whilst maintaining uniform product quality and eliminating the need for routine grab-sampling for off-line testing. Designed for robustness, ease of installation, lowest maintenance costs, and maximum long-term stability, the CM710 is supported by NDC’s worldwide Customer Care Team.

Bolt‘N Go - Drop Forged Conveyor Chain

Leeds, UK -- Flight installation and chain assembly made easy. 4B Braime is pleased to announce the launch of the new revolutionary Bolt‘N Go drop forged chain system.

The new Bolt‘N Go system is a very flexible system of high strength hollow pins, heavy duty washers and nylock nuts, which enable bolts to pass through to connect the links together and attach flights.

There are no circlips to become loose and there is no intricate assembly. There is no welding required on the flights, no need to remove chain from the conveyor for installation, and no issues with strength. Just bolt the links and the flights together. It’s easy, simple and reliable.

The Bolt‘N Go system’s advantages:
- No more welding of flights
- No need to remove chain from conveyor
- Reliable secured link, pin and flight
- Reduced maintenance cost and down time
- Steel or plastic flights

Founded in the UK in 1971, 4B Components, Ltd. has been an industry leader in developing high quality, innovative, and dependable material handling components for the agricultural and industrial sectors. From elevator buckets to forged conveyor chain and level monitors to hazard monitors, 4B is a company you can rely on for the equipment you need.

Quick-Access Screener Speeds Cleaning

MILLBURN, NJ -- A new “Air-Lift” quick-access system for circular vibratory screeners allows rapid interior cleaning, inspection and screen changes while reducing manual effort, according to Henry Alamzad, president of Kason Corporation.

The device consists of two vertically mounted air cylinders that are located on opposing sides of any circular screener and affixed to mounting brackets on the lower and upper screening frames.

To operate, a quick-acting band clamp connecting the frames is removed and a remote air valve is actuated, raising the upper frame(s). The procedure is reversed to reconnect the frames.

One entire raise/lower cycle, including disconnection and reconnection of the frames, can reportedly be accomplished in five minutes, reducing downtime during inspection, cleaning and screen-changes. In addition, one operator can now perform what was previously a two-person task, depending on screen diameter.

Safety features include a safety lock-out that secures the frames in the open or closed position when the upper screener housing is raised or lowered, safety bars that prevent the housing from accidentally descending while in a fully-raised position during screen changes or wash down, and optional enclosures that cover the pneumatic cylinders.

Click to watch Kason's Air Lift in action.

The Air-Lift device is available on any new Kason screener, and can be retrofit to any circular vibratory screener of any make or model from 40 in. to 84 in. (1000 mm to 2135 mm) in diameter, including screeners having single or multiple decks, and screens with or without center holes and/or anti-blinding devices.

Kason screeners equipped with the device are available in mild steel, or in stainless steel finished to 3-A, cGMP, USDA, FDA or industrial standards.

The screening assembly is suspended on springs that allow it to vibrate freely while minimizing power consumption and preventing vibration transmission to the floor. Beneath the assembly is an imbalanced-weight, gyratory motor that creates multi-plane inertial vibration for the purpose of controlling the flow path of material on screen surfaces and maximizing the rate at which material passes through the screen.

The company manufactures a broad range of circular vibratory screeners, centrifugal screeners, and circular fluid bed dryers, coolers and moisturizers.

Mr. Gentile wants to level off powder in a mold:

I am trying to level off powder that is dispensed into a mold and I am not sure of the best technique.

Our process at this time is lab scale, and not fully automated. We have a mold which will be filled by weight with the powder. Currently this is done by hand, but we intend on having the powder metered into the mold.

Our current leveling technique is done by hand, with a fixed height doctor blade that has slits cut into it...similar to a comb. This technique works OK, but it doesn't lend itself to automation, and I'm sure we still get some density variation after we press the part despite the fact the part comes out with only .001" thickness variation over a 1.5" span.

Can someone enlighten me on techniques that are used to level powders in a mold? the process will need to be something that can be scaled up for automation purposes. (to post reply, click here)

Mr. Sam wants to calculate load based on free-falling ore:

I'm hoping to get some guidance on my problem here.  We have a hopper with inlet dimension 9' x 20' and outlet dimension 5' x 20' and its height is 12'. Below this hopper is apron conveyor. We use vertical skirting to seal the material from flowing to sides and back of apron conveyor (the hopper construction is similar with feed chute).

80 tons of nickel ore is dumped from dump truck directly to empty hopper and fill the hopper and also create impact on apron conveyor due to free fall. Nickel Ore is sticky material (limestone look alike) with 30 % moisture.

I want to know how to calculate load/pressure distribution on apron due to impact from free-fall ore because I want to determine the minimum required power needed for this apron conveyor. Is there any formula to calculate this? I've read some silo books and it only mention about pressure distribution along silo/hopper wall.  (to post reply, click here)
