Selecting the right conveyor or combination of conveyors for your particular
application is easy with Bunting's standard magnetic conveying
equipment. Utilizing standard, pre-engineered components,
Bunting can offer conveyors to handle virtually any type of
ferrous part or scrap by tailoring the physical dimensions
to fit the application.
This selection guide is designed to provide as much detailed
information as possible to assist you in selecting and ordering
Bunting Standard Magnetic Conveyors. You will find a variety
of equipment specifically designed to solve your material
handling problems, along with the detailed dimensions necessary
to determine which will best suit your needs.
While, in some cases, magnetic handling and conveying jobs will
require modification of basic Bunting Conveyors, all units
will utilize standard, modular parts to provide an economical
alternative to custom conveyors and systems. Bunting conveyors
can be used alone or in combinations to accomplish a variety
of material handling tasks.
GUIDE TO CONVEYOR SELECTION
To determine which Bunting Magnetic Conveyors will best
serve your needs, five factors must be considered. The following
specifications have been prepared to help you determine
what conveyor style, angle of incline, belt speed, physical
dimensions, and optional equipment will best fit your application.
DETERMINING PHYSICAL SPECIFICATIONS
Conveyor Style
SC Series Magnetic Curved Slider Bed - Used when
transporting unstable, irregularly-shaped parts, large/bulky
items, or parts which are too heavy to negotiate an abrupt
change of direction.
SP Series Magnetic Pulley Corner Section - Used when product
load is heavy or when production rates require belt speeds
above 120 FPM.
SH Series Magnetic Horizontal Conveyors - Used horizontally
or at inclines up to 15 degrees.
Angle of Incline
Steep incline offer the advantage of minimum floor space.
Shallower angles are used to transfer large parts or to reduce belt
pull when using a Magnetic Curved Slider Bed section under
heavily loaded conditions.
Belt Width
In most cases, belt width is determined by the size of the
product to be conveyed. When moving small parts, we suggest
that the belt be at least 3'' wider than the parts being
conveyed. For scrap conveying, consult Bunting Engineering
Department.
Vertical Height
Vertical discharge height is directly related to the demands
of the equipment being fed. Select a steeper angle of incline
when floor space is at a minimum.
Horizontal Extension Length
Conveyors requiring additional horizontal length can be
ordered by adding an extension to the basic model length.
The length of a horizontal extension is directly related
to the angle of incline and vertical height desired. Lower
angles of incline will require smaller extensions, while
steep inclines will require longer extensions to achieve
a similar overall length.
EXAMPLE
The corresponding horizontal or ''L'' dimension for an SP
708-10-00 per chart is 5'-1''. This figure falls approx.
1 ft. short of a desired 6'-1'' dimension, thus indicating
the need for a 1 ft. extension to the basic model. The extension
is described as an ''X'' dimension and the overall length
of the conveyor computed by adding the ''L'' dimension (5'-1'')
to the ''X'' dimension (1'-0''). Thus, the model number
created is SP 708-10-01
Cross-Section View of Bunting Magnetic Conveyors
If you could see through the moving belt, you would find one
or more rows of stationary magnetic elements containing
specially selected magnets and steel pole pieces. These
permanent magnets form an invisible ''lane'' of concentrated
magnetic force that holds the parts being conveyed against
the moving belt. At product release points, special magnetic
elements gradually reduce this holding force for smooth
transitions and part removal. The number, size, strength,
and reach-out of the magnetic elements are matched to your
application. An experienced design team with a broad line
of magnetic conveying products can keep your costs down
by providing exactly what you need.

DETERMINING PART NUMBERS
Bunting utilizes a nine-digit part number to describe each conveyor
according to its physical dimensions. The two-letter prefix
indicates the frame series and style of the conveyor. The
following three digits specify the angle of incline and
belt width, while the remaining two pairs of digits relate
to the vertical height and horizontal length extension,
respectively.
INCLINED VERTICAL CONVEYORS
Part numbers for inclined and vertical conveyors are constructed
by selecting the conveyor style, angle of incline, and belt
width desired (See PART NUMBER EXPLANATION chart below.)
Vertical height of the conveyor is indicated in one foot
increments by the ''Y-Y'' suffix, while horizontal extensions
to the basic conveyor length are designated by the ''X-X''
suffix. Since all part numbers must contain nine digits,
conveyors which do not require horizontal length extensions
are identified by a ''00'' number as the ''X-X'' suffix.
HORIZONTAL CONVEYORS
Part numbers for horizontal conveyors are also constructed by
establishing the conveyor series. Belt width and horizontal
length (See PART NUMBER EXPLANATION chart below.) The ''Y-Y''
suffix of the part number does not apply in specifying a
horizontal conveyor, and should be identified by a ''00''
number. The ''X-X'' suffix, however, identifies the entire
horizontal length of the conveyor based on the values found
in its corresponding dimensional tables. An entry of ''12''
as the ''X-X'' suffix, then, would represent an overall
horizontal length of 12'-4''.
