Why DIAMOND chains are used in mining
In the mining industry, roller and conveyor chains work under demanding conditions: abrasive dust, impact loads, moisture and continuous shifts. DIAMOND chains are used in equipment such as crushers, mills, screens and conveyor belts, where the chain must maintain power transmission or material transport.
In crushers and mills, chains transmit motion from the gearmotor to the shafts that crush or grind the ore. In vibrating screens, chains can drive the exciters that generate the vibration needed to classify the material. In conveyor belts, chains are used in drag systems, feeders or slat conveyors that move the ore along the process.
When choosing a chain for mining, it is advisable to consider the type of load, the operating speed and the presence of contaminants. We sell these chains and help you identify the correct reference for your equipment.
DIAMOND roller chains for power transmission in mining equipment
DIAMOND roller chains are used to transmit power between shafts in crushers, feeders and other mining equipment. They are standard-pitch chains, such as series 40, 50, 60 and 80, which are mounted on sprockets or toothed wheels. In mining, large-pitch chains are also used, such as 200H.
One example is the 40LG roller chain, from series 40. Another option is the 60LG, from series 60, with a 3/4-inch pitch, which is used in mill or agitator drives.
To order a roller chain, you need to know the pitch, the width between inner plates and the roller diameter. It is also useful to know the number of links or the total length. If you have the DIAMOND code stamped on the links, such as 200H, you can request a quote for it directly with us. We distribute DIAMOND chains and quote the reference that corresponds to your equipment.
DIAMOND conveyor chains for ore handling
DIAMOND conveyor chains are used in conveyor belts, bucket elevators and drag conveyors that move bulk ore. Unlike roller chains, these chains usually have larger links, with straight or curved side plates, and may include attachments to hold buckets or slats. They are designed to support the weight of the material and resist abrasion.
In mining, conveyor chains are used in crawler feeders, submerged chain conveyors and bin extraction systems. For example, S81X, 43SB and 63SB are DIAMOND conveyor chain references.
When ordering a conveyor chain, it is key to indicate the pitch, the inner width, the pin diameter and whether it has attachments. It is also advisable to know the total length and the number of sections. If you have the DIAMOND code, such as S81X, you can send us a photo of the chain and we will quote the exact replacement. We work with DIAMOND chains for mining and advise you on selection.
How to identify the correct DIAMOND chain on your equipment
To order a DIAMOND chain, you first need to identify what type of chain your equipment uses. Check whether it is a roller chain (with rotating rollers between plates) or a conveyor chain (larger links, often with straight plates). Also check whether any code is stamped on the links, such as 40LG or S81X, which makes quoting easier.
If you cannot find the code, measure the chain pitch: the distance between the centers of two consecutive pins. Also measure the inner width between plates and the roller or pin diameter. With those measurements, we can identify the equivalent DIAMOND chain. It is important to measure accurately, because a difference of millimeters can change the reference.
In mining equipment, chains are sometimes very worn and the measurements do not match the originals. In that case, it is advisable to consult the equipment manual or look for the reference on the sprocket. If you do not have the manual, you can send us photos of the chain and the sprocket, and we will help you identify the correct chain. We sell DIAMOND chains and know mining applications.
Data you should send to get a quote for DIAMOND chains
To quote a DIAMOND chain, we need some basic data. If you have the DIAMOND code, such as 60LG or 43SB, that code and the quantity of meters or links are enough. If you do not have the code, send the measurements: pitch, inner width, roller or pin diameter, and total length. A photo of the chain and the equipment also helps.
Also indicate the application: whether it is for a crusher, a mill, a screen or a conveyor belt. That allows us to verify that the chain is suitable for the load and speed. If the chain has attachments, such as buckets or slats, specify the type and the distance between attachments.
You can send us the data via WhatsApp or email, and we will reply promptly with the quote. If your chain is from another brand, we can also look for the DIAMOND equivalent. We distribute DIAMOND chains for mining and advise you with no obligation.
Common mistakes when ordering or installing chains in mining
One of the most common mistakes is ordering a chain by serial number without verifying the pitch. For example, a 60 chain has a 3/4-inch pitch, but two chains of the same pitch can differ in width or plate type. It is always advisable to confirm the measurements, especially if the original chain is very worn.
Another mistake is not considering the type of lubrication. In mining, chains work in environments with dust and moisture, so they need adequate lubrication to prevent premature wear. When installing a new chain, check the alignment of the sprockets and the correct tension: a chain that is too tight or too loose reduces its service life.
It is also common not to order the correct number of links. If the chain is for a conveyor, measure the total length needed and add a margin for adjustment. If you have doubts, consult us before cutting the chain. We help you avoid mistakes and choose the right DIAMOND chain for your mining equipment.

Frequently asked questions
Which DIAMOND chain is used in a crusher?
Crushers use roller chains, such as 40LG, 60LG or 200H. The choice depends on the pitch and the load. Send us the code or the measurements and we will quote the correct chain.
How do I identify the pitch of a DIAMOND chain?
The pitch is the distance between the centers of two consecutive pins. Measure it with a caliper and compare it with standard chain tables. If you have the stamped DIAMOND code, such as S81X, send it to us and we will identify it.
Can I use a DIAMOND chain on a mining conveyor belt?
Yes, there are DIAMOND conveyor chains for drag conveyors, such as S81X or 43SB. We need to know the pitch, the inner width and whether it has attachments to quote the right chain.
What data do I need to quote a DIAMOND chain?
If you have the DIAMOND code, that code and the quantity are enough. If not, send the measurements: pitch, inner width, roller or pin diameter, and total length. A photo of the chain and the equipment also helps. We will reply promptly.
Does MR Accesorios Industriales distribute DIAMOND chains in Argentina?
