Cement Plant Application Areas for Rotary Valves, Slide Gates and Dump Valves


Rotary airlock valves (rotary valves / feeders) in a Cement Plant:


Coal Feeding For Clinker Processing
Very High Abresive,
80 kPa Pressure,
<95 micron particle size


5 Bins — rotary feeders dosing corrective materials into the raw-mill feed.
6 Raw Mill — under the raw-mill dedust filter/discharge.
7 Dedusting (ESP) — discharge of collected raw-meal/kiln dust from the precipitator hoppers.
9 Cyclone Preheater — meal/dust discharge from the cyclones.
11 Coal (Mill) — under the coal-mill baghouse, plus pulverised-coal dosing to the kiln/calciner (this is a severe-duty / RFS-type point).
14 Air-to-air cooling / 15 Dedusting — clinker-cooler dust discharge (hot, abrasive).
16 (coal-mill dedust cyclone) — dust discharge.
18 Cement Mill / 19 Filtering — cement-dust discharge from the mill filter/separator.
20 Bulk Loading / 21 Packing — under the loading/packing dedust filters.
Fly Ash Handling
Very High Abresive,
15 kPa Pressure,
<4mm particle size
Temperature 200C
Alumina Processing
Very High Abrasive Alumina
15 kPa Pressure,
<45 mikron particle size
350C Fly Ash resistance
Clinker Feeding
Very High Abrasive
20 kPa Pressure,
<25 mm particle size
Air Seal Critical
Material Buildup and Clogging critical
Slide gates (isolation) in Cement Plants:
3 Storage and 4 Additives — under the storage piles/corrective-material bins.
5 Bins — bin outlets (above the feeders).
8 Homogenizing — raw-meal silo outlet.
16 Clinker Storage — clinker silo/bin outlet.
17 Gypsum/Minerals — additive-bin outlets.
18 Cement Mill feed and 20 Bulk Loading cement-silo outlets.

Dump / flap valves (hot, abrasive, lumpy) in Cement Plants:
13 / Clinker Cooling — hot clinker/dust discharge under the grate cooler.
15 Cooler Dedusting — hot cooler-dust discharge.
7 ESP and 9 preheater dust catcher — where the collected dust is hot (>150–200 °C).
Anval DH
Opening sizes: 150, 200, 250, 300, 350mm
Handling Hot Clinker In Cement Plant Cooling Under Grate System
