For almost half a century, I-MAK has been developing special solutions for the quarry and stone crushing sector. In South African giant mines, Polish salt mines, Moroccan phosphate pits and Indian quarries, I-MAK solutions are used to crush, scan, wash and transport tones of stones, sand and minerals every day.

I-MAK products are adapted to dusty environment, heavy loads and non-stop operation. The special features of I-MAK gearboxes contributed to lower operational costs, reduce energy consumption and minimum downtimes. The bevel geared motors – IRK series are perfect alternatives to shaft couplings and belt drives. Designed for direct coupling with the conveyor drums, the IRK Series are increasing the security of the installations, in the same time they are providing increased protection against the water and dust intrusions.

To keep a close eye on the technology and demand evolutions, I-MAK works in close collaboration with equipment manufacturer to design and adapt the geared motors to the requirement of this demanding sector. With the increase of raw materials and mineral prices the sector is getting ready for a new wave of investment in 2019-2022 period.

I-MAK also developed a tight network of distributors and service centers to provide fast assistance and support on the exploitation fields. These centers are supported by I-MAK technical centers around the world that supply complete geared motors and gears set in reduced time.

I-MAK propose a large range of products and solutions for the mining and quarries industries, helical geared motors IR Series, bevel geared motors IRK Series, shaft mounted gearboxes IRO Series, shaft mounted gearboxes IRN Series, bevel helical heavy duties gearboxes A Series, parallel shaft geared motors YP Series. As our new solution for 2019, we are now proposing monitoring solutions for our customers. Using a special set of sensors and software our customers are now able to follow the health and dynamic of our gearboxes and electrical motors. Our engineers our now working on the standardization of this product to provide it to a larger range of customers.

Van Tongeren America unveils jet fabric filter dust collection system



Process equipment manufacturer, Van Tongeren America, has unveiled a dust collection system that is proven to remove more than 99% of particulates from an airstream. This meets environmental emissions standards.

The dust collection system features a proprietary design that controls airflow direction through the baghouse. The system sets the gas entry inlet near the top of the pulse jet collector, directing a portion of the particulates into the hopper below before contact with the filter bags.

With the system, dust load on the bags is reduced, their service life is extended, and downtime for maintenance is minimized. A smaller unit on a more compact footprint can be specified than with traditional baghouse systems.

The collector has been developed to provide the final cleanup step in dry particulate screening and classifying systems. The system is able to capture fine particles from processing aggregates, manufactured sand, cement, lime, salt, fertilizer, and a variety of other materials at a wide range of temperatures. The modular system comes in a range of nine different standard sizes, as well as custom sizes to match the proper amount of filter bags and cloth area with the airflow rate and dust load.
