Silo Discharge Sleeves & Conveying Socks

KMH Spares supplies rubber discharge sleeves and conveying socks for silos and aggregate handling across Ireland and the UK. Also known as rubber socks, cement socks or conveying sleeves, these flexible sleeves channel material from the silo or conveyor outlet, contain dust during discharge, and take the wear so the surrounding equipment does not.

Because they sit directly in the flow of abrasive material, discharge sleeves are a consumable wear part, and keeping the right size on hand avoids downtime when one needs replacing. We supply a range of diameters to suit silo discharge, aggregate conveying and chute applications, with reliable lead times so a planned replacement does not become an unplanned stoppage.

What our discharge sleeves are used for
▸ Silo discharge channelling cement, powder and aggregate from the silo outlet while containing dust
▸ Aggregate conveying flexible connection on conveyors and loading points where abrasive material would wear a rigid fitting
▸ Chute and loading directing material into trucks, hoppers and bins with dust containment
▸ A range of diameters sized to common silo and conveyor outlets, so you can match or replace an existing sleeve directly

Choosing and replacing a discharge sleeve

Diameter

The main thing to get right. The sleeve must match your silo or conveyor outlet diameter. If you are replacing an existing sleeve, measure it or quote its size and we will match it directly.

Material and wear

Discharge sleeves are a wear part by design, taking the abrasion so the rigid equipment around them lasts. For abrasive materials, expect to replace them on a schedule, and keep a spare on hand to avoid downtime.

When to replace

Replace when you see thinning, splitting or perishing of the rubber, or dust escaping where the sleeve no longer seals. A worn sleeve stops containing dust and lets wear reach the equipment it was protecting.

Silo Discharge Sleeves FAQs

What is a silo discharge sleeve or sock?

A flexible rubber sleeve, also called a rubber sock, cement sock or conveying sock, fitted at a silo or conveyor outlet. It channels material during discharge, contains dust, and acts as the wear part so the surrounding equipment is protected.

What sizes do you supply?

We supply a range of diameters to suit common silo and conveyor outlets; 220mm, 280mm, 320mm, 450mm. If you are matching an existing sleeve, tell us its diameter and we will confirm the correct replacement.

How often do discharge sleeves need replacing?

As a wear part, service life depends on the material and throughput. Abrasive materials wear them faster. Replace when you see thinning, splitting or dust escaping, and keep a spare on hand to avoid downtime.

Do you supply across Ireland and the UK?

Yes. KMH Spares supplies discharge sleeves and conveying socks throughout Ireland and the UK, with reliable lead times so a planned replacement does not become an unplanned stoppage.
