On 12.06.2020, the second mobile stone crushing machine equipped with a hybrid engine was sold to Vao Paas OÜ.

In June 2020, Paekivitoodete Tehas sold another such crushing-sorting line requiring minimal electricity resources. The Keestrack stone crushing machine R6e-C6e has a fully electric rotor transmission. This device, with an additional conveyor S1, was equipped with an advanced power supply system and individual mechanical units!

The Keestrack R6e-C6e line is characterized by the fact that the device can also be used close to residential areas, as it generates much less noise and dust. Another great advantage of the crushing machine is that it runs on both electric and diesel engines, which in turn allows to significantly increase productivity and reduce the cost of crushed stone production and consumption of energy resources, and increase production profitability accordingly.

With extended options, the Keestrack R6e-C6e crusher can be customized for specific applications.

The Keestrack stone crushing machine is a whole class larger and more productive device than those used in Estonia so far.
