Key Players in Hopper Dryer Market Adopting Strategies to Promote Business Growth Some of the main players in the hopper
dryer market are ACS Group; Bry-Air Conair; Dri-Air Industries Inc.; Kenplas Industry Ltd.; Motan Colortronic; Novatec, Inc.; Summit Systems; and Yann Bang etc.
Because the Hopper Topper covers the business end of the auger, which turns in the hopper
as it's powered by a power take-off shaft of a tractor, injuries can be minimized, Dismuke said.
Because the material in the hopper
is fully dried, off-loading can be done either in batches or continuously.
The horizontal conveyor has multiple discharge ports to apportion material across the length of the discharge hopper, and automatically starts and stops to maintain a preset fill level in the hopper
. A small-diameter, rotating agitator along the bottom of the hopper promotes uniform discharge through an adjustable screen that spans a gap along the hopper bottom.
Usually, there has been little or no powder testing, so the material's flow properties are not accommodated in the hopper
The ram position indicator shows the position of the ram or plunger in the hopper
of the mixer, and is considered part of the hopper assembly, it is an extremely valuable tool for optimizing the batch weight for both Banbury and Intermix mixers.
The open design enables users to load more items in the hopper
. Rolling on phenolic casters, the hopper is designed to easily move from one location to another.
When the crane operator has loaded approximately 450 kg, a button in the cab is pressed enabling the CPU to record the amount of steel in the hopper
The X-ray pictures show distinctive patterns of dark, sloping bands, which correspond to areas where the sand is more loosely packed, or less dense, than elsewhere in the hopper
. The bands form within a well-defined, narrow central region extending from the hopper opening to the top of the sand wedge.
The result is that despite a nominal 4-hr residence time in the hopper
, some material exits the hopper in as little as 2.5 hr, and that material can contain twice as moisture as the average for the hopper as a whole.
In the hopper
assembly, there is a ram (Banbury terminology) or plunger (Intermix terminology) that can be raised or lowered, allowing raw materials to be added into the mixer and then forced down into the mixing chamber.
The Mini-Feed ensures that the dried material is kept in the hopper
until the receiver calls for new material.
Two rollers on the valve close and pinch off the flow of material in the sleeve at an elevation that is actually below the bottom opening in the hopper
. When the material is ready to be discharged, the rollers open and the head of material drops, emptying the hopper quickly and completely.
A new manifold allows use as a central dryer for multiple processing machines, and a new sight glass allows a sensor to confirm material level in the hopper
. New easy-access surge hopper and built-in drain chute on resin canisters speed material changes.
Level sensors can also be provided in the hopper
to synchronize with the roller section motor in order to coordinate batch evacuation from the SPM with the mixer batch cycle time.
