P250-K2 EP-HD Heavy Duty Interlocked Pan Conveyor Chain for Cement Plants
P250-K2 EP-HD heavy duty interlocked pan conveyor chain: 250 mm pitch, 30 mm pin, 90 mm sidebar, 650 kN.
The SHINING P250-K2 EP-HD heavy duty interlocked pan conveyor chain is the high-tonnage build of our P250-K2 EP pan conveyor line for cement plants. It runs on the same 250 mm pitch with 90 mm sidebars in 12 mm plate, a 30 mm pin in a 45 mm bush, attachment plates at every pitch for the pans, and a minimum tensile strength of 650 kN.
It is the chain for the stretches where a pan conveyor works hardest: hot clinker off the kiln and cooler discharge, long centres and steep climbs to the clinker silo top, with full pans and abrasive material all day. The interlocked joints hold the line on the way up, so the pans stay butted edge to edge.
The light-duty build of the same P250-K2 EP line has its own page - see the P250-K2 EP Interlocked Pan Conveyor Chain.
Kiln and cooler discharge: the highest-tonnage hot clinker duty, straight off the kiln outlet and cooler.
Long steep inclines: long centres and grades up to 37 degrees on the climb to the clinker silo top.
Heavy pan conveyor retrofit: dimension-for-dimension replacement for a worn heavy chain on an existing conveyor.
High-capacity clinker silo feed: full pans on long centres, day in and day out.
The outer link plates are waisted at both ends and the inner plates carry raised bosses beside the pitch holes. The joint closes against these stops: it articulates freely in the line of travel and cannot fold back on itself. On the loaded up-run the links cannot rotate back and open a gap between the pans - the hot clinker stays on the pans.
The deep, heavy sidebar carries the bending load of a full pan over long centres, and the bent form keeps the carrying line close under the material bed.
Pans bolt to the attachment plates at every pitch, so the load is shared along the chain line - the spacing is set for the heaviest clinker loads.
The 40Cr/42CrMo pins are surface induction-hardened and the 20Cr/20CrMo bushes are carburized, so the wear is taken at the pin and bush bearing surfaces where it can be managed, and the chain keeps its pitch.
Sidebar height, plate thickness and the fixing pattern are made to your drawing or to a worn link, so the chain drops into the existing conveyor.
Matching sprockets are built from the same works to the same drawing, so chain and sprocket wear together.
The table gives the heavy-duty build of the chain: the outline and joint dimensions with the tensile rating.
| Parameter | P250 heavy duty |
|---|---|
| Chain pitch P (mm) | 250.0 |
| Overall link length L (mm) | 410.0 |
| Sidebar height H (mm) | 90.0 |
| Height above pitch line h1 (mm) | 70.0 |
| Overall height h2 (mm) | 115.0 |
| Sidebar thickness T (mm) | 12.0 |
| End-to-pin distance E (mm) | 80.0 |
| Pin diameter d1 (mm) | 30.0 |
| Bush outside diameter d2 (mm) | 45.0 |
| Width between inner plates b1 (mm) | 62.0 |
| Tensile strength Q min. (kN) | 650 |
Material and heat treatment are selected for the duty. The sidebars and attachment plates are cut from quenched-and-tempered 40Cr/40Mn alloy steel - they carry the chain load. The 40Cr/42CrMo pins are surface induction-hardened and the 20Cr/20CrMo bushes are carburized, so the wear is taken at the pin and bush surfaces where it can be managed, and the full service life of the chain is extended.
Matching sprockets are covered too: the customized sprocket built for this 250 mm pitch chain has its own page - see the P250M14-C-8T Customized Sprocket.
SHINING has manufactured conveyor chain and sprockets for cement plants for over twenty years, with drop forging, welding, machining and heat treatment under our own control. Every production batch is tensile-tested before shipment, and our quality system is certified to ISO 9001:2015 (46026Q00958R053) and ISO 14001:2015 (46026E00959R053).
We build to interchange. Send the OEM part number, an old link or a drawing, and we will confirm the match and reproduce it dimension-for-dimension, with sprockets and attachments cut to suit.
Standard production lead time is 60 days from receipt of the order and confirmation of the drawing. For breakdowns and planned shutdowns we can discuss an expedited slot - tell us your date and we will plan the delivery around it.
Our engineers support station and duty review, chain selection, wear and elongation analysis, maintenance planning, and genuine replacement parts. Send your conveying duty and we will size the chain for you.
Tell us your duty, your drawing or the OEM part number, and our engineers will come back with the right chain and a price. Email the sales team at sales@shiningco.com.
