ISM HOOK AND SHAKER SCREENS

ISM’s hook screens and shaker screens are typically made with stainless steel market grade woven wire or bolting cloth but can be made with whatever screen fits your needs. Industrial Screen & Maintenance can also supply custom screen or bolting cloth, woven to your specifications. Orders typically ship within 24 hours. A minimal lead time is necessary for custom woven screen and bolting cloth.

When ordering, follow these steps to insure proper fit of hook screen.

1. State which edges are to be prepared with hooks or fitted with hook strips. Specify length of hook strips.

2. Give accurate outside dimension of screen. (See illustration A below.) Measure old screen from outside of one bend to outside of other bend.

3. Be specific about angle and length of hook as shown in illustration B below.

4. When screens are slotted, specify if slots are parallel or perpendicular to hook strips.

5. Specify size and make of vibrator.

When installing, follow these steps to insure screen is not damaged.

1. Be sure there is ample clearance for tensioning on vibrator screens. (See illustration C below.)

 2. Vibrator screens need time to seat into place. Install new screen under partial tension without a load and allow it to vibrate for a brief period of time to seat properly. Then tighten fully to proper tension. Loose installation will cause premature breakage.

3. Bucker up or crown bar rubber strips should be checked every time you change screens. Remember – The rubber wears from the bottom on the rails and wear is not always visible.

4. Check the sizes of all pieces being installed. Also check to make sure screens have hook strips parallel. Tension uniformly to maintain screens in parallel.
