Introduction
General The Martin®DT2 Inline Cleaner XHD is used in conjunction with a head
pulley primary cleaner such as the Martin®Primary Cleaners. To introduce
product back into the product flow, a Pre-Cleaner is installed on the face of the
head pulley. On a dual cleaner system, the Secondary Cleaner is installed
immediately following the Pre-Cleaner to remove stubborn material left on
the conveyor belt. If a Pre-Cleaner cannot be used because of space
limitations, the Secondary Cleaner is installed alone. If the material-handling
process or product could be affected by contamination from the use of these
belt cleaners, the user is responsible for taking the necessary steps to prevent
contamination. Consult Martin Engineering or a representative for alternate
belt cleaners or belt cleaner locations to use where contamination may be an
issue.
The Martin®DT2 Inline Cleaner XHD contacts the belt as it leaves the head
pulley or another accessible position on the return belt with proper support.
The blades of the Martin®DT2 Inline Cleaner XHD, when tensioned, lay in
the direction of belt travel giving a negative angle and presenting no snag or
danger to the belt or splices.
The cleaner can be supplied or retrofitted with a variety of cleaning blades.
These include:
• Tungsten Carbide—For very abrasive materials.
•Urethane
• Reversing—Above options in reversing form for belts that drive in both
directions.
Note: When mounted slightly away from the head pulley or pressure roller,
the Martin® DT2 Inline Blade will handle small amounts of belt reversal or
roll-back with no adverse effects. When fitted with Reversing Blades, the
Martin®DT2 Inline Cleaner XHD becomes a fully-operational reversing belt
cleaner.
Installations
Without
Chutework
These procedures were written for equipment that is being installed on
enclosed pulley chutework. If the pulley is not enclosed, the equipment should
be installed using the best available field resources and methods to ensure that
the critical dimensions are followed for proper installation.
Belt Cleaner
Inspection Access
If the belt cleaner is installed on enclosed pulley chutework, a Martin®
Inspection Door should be installed. Martin®Inspection Doors are available
from Martin Engineering or your representative.

Installing Belt Cleaner
IMPORTANT
Read entire section before beginning work.
To install the belt cleaner, follow the procedures corresponding to the
following steps:
WARNING
!
If installation is to be done in an enclosed area, test
atmosphere for gas level or dust content. Follow all welding
and safety guidelines. Protect belt surface from weld splatter
with appropriate shield.
NOTE
For original equipment installation, where cleaner cutouts
and brackets have been fabricated into the chute during
construction, ignore steps 1, 2 and 3.
NOTE
Solid backing of the blade is essential to ensure proper
operation and efficient cleaning. Install the cleaner adjacent to
the head pulley or a flat pressure roller to obtain best cleaning
results. See Figures 1a and 1b.
NOTE
For installation on enclosed head pulley chutework, draw all
dimension lines on chute wall. In applications where head
pulley is not enclosed, use the best available field resources
and/or methods to ensure that these critical dimensions are
followed for a proper installation.
Locating Cleaner
Centerline
1. On the return side of the belt, locate the tangent point at which the belt
leaves the head pulley. Measure a distance 2 in. (50 mm) and draw a line
perpendicular to the belt at this point. See Figures 1a and 1b.
2. Note: For installation below pressure rollers, mark the vertical line 2 in.
(50 mm) from the centerline of the roller. See Figure 1a.
