Bulk-bag discharge unit has
low headroom requirements
This patented system (photo) is
custom designed for the safe discharge
of product into the user's
process. It features several
stainless=steel features, including
the Flo-Lock discharge spout-closure
system, which is said to quickly
halt material flow and allow for partial-bag
discharge. The Seal-Master
bag-spout access chamber is designed
for easy operator access,
and the Sure-Seal bag spoutclamping
system is designed to
minimize dust escape. The system
also includes the Flo-Master
bag-massaging system to enhance
powder flow, and pneumatic
piping with rigid 304 stainlesssteel
air lines. - Material Transfer,

The process of relining
grinding mills just got easier
The process of relining a grinding
mill can be challenging, even for the
most experienced crew, says this
company, due to confined spaces,
hot environments and complex
tasks. The 7-Axis Beam Mill Reline
Machines (MRM; photo) can be maneuvered
using a conventional rail
arrangement or tire-drive system,
providing increased flexibility for
transport around the mill deck. Its
traveling liner cart can be maneuvered
for rotating liners, and a crane
with seven degrees of freedom for
manipulation of the liners inside the
mill ensures safe, efficient and reliable
operation, says the company. Safety
features include remote control operation,
state-of-the-art electro-hydraulic
proportional control blocks
with advanced fault detection, safe
machine design and safety-rated
components and systems, says
the manufacturer. - Outotec Oyj,

Advanced screeners can
handle many particle sizes
Partnering with German manufacturer
Rhewum GmbH, this company
offers the Rhewum line of screening
equipment (photo). The latest addition
to this company's advanced
screening equipment family are large,
rectangular screening machines that
incorporate direct excitation of the
screen cloth to achieve high throughput
at lower micron size, says the
company. The customized machines
are available in numerous sizes and
can have multiple decks to enable
the production of several products at
the same time. The machines feature
electromagnetic elements mounted
on the side of the screen housing,
which directly transfers energy into
the screen mesh while the machine
body remains static. - Elcan Industries,

Sanitary, high-lift dumper
handles powders in boxes
Constructed of stainless steel that
is finished to food, pharmaceutical
or industry standards, the Tip-Tite
High-Lift Box/Container Dumper
(photo, p. 32) discharges dustfree
into vessels that are 6 to 10 ft
above the plant floor. The containers
are loaded at the floor level and
hydraulically sealed against a discharge
hood. The assembly is then
hydraulically elevated and tipped,
causing the discharge hoot spout
to seat against a gasketed receiving
ring installed on any receiving vessel
or process equipment. Opening
a pneumatically actuated slide gate
valve at the spout outlet allows controlled,
dust-free discharge, while
closing it allows partially empty
boxes to be returned to the plant
floor. The unit accommodates Gaylords
and other boxes from 36- 48
in. (915-1,220 mm) side length, and
39-44 in. (990-1,117 mm) overall
height. It can also be constructed
