Automatic bar counting and separation system installation in Saudi Arabia

Project: Installation of automatic bar counting and separation system in Rajhi steel, Saudi Arabia

Time: November 29, 2022, to January 5, 2023

The engineers of LMM Group (DBM parent company) came directly to the factory site on November 29th for on-site inspection.

The customer wants to use his own center extension, so the site has not been dismantled. After on-site measurement and inspection, it is found that if we use our center + flip, the customer needs to remove a large beam and the existing center extension, which will damage the existing structure and require a lot of Time and energy, after evaluating the customer’s idea, the engineers proposed that we can use our counting + end division + customer’s own steel division, which is very feasible, and decided to implement this plan after negotiating with the customer.


After deciding on the plan, everyone put into the intense installation and transformation work.

At the same time, hold a joint meeting with relevant personnel to explain our installation plan and other conditions, and clarify the work that each person in charge needs to do.

The customer temporarily reported that due to on-site reasons, the repairing time of the rolling workshop was extended, and the customer liked the installation video we sent to Turkey very much. The customer decided to dismantle their current center extension and install our center extension.

Once a new installation plan has been developed, implementation begins

At this steel mill in Saudi Arabia, we replaced Danieli’s steel-splitting counter. Let me share with you the comparison between Danieli’s steel-splitting counter and our counter.

Danieli steel bar counting system


1. The screw rod needs to be replaced every time a specification steel bar is changed in the Danieli counter. It takes at least 10-20 minutes to change the screw rod, but our equipment only needs 5 seconds to click the mouse to change the specification.

2. The spare parts of Danieli equipment are very expensive. I learned from the customer that each screw costs 10,000-12,000 US dollars, and it needs to be replaced every year. A few screws are enough for the price of our equipment.

3. The accuracy rate of Danieli equipment is very low, while the error rate of our equipment is within 5/10000, which is far superior to the other party in terms of accuracy rate.

4. Counting speed. It was found on the spot that the speed of Danieli’s steel counter chain is more than 90-100 mm/s, and the speed of our steel counter chain is allowed to reach 570mm/s
