Van de Kraats en Bouw B.V. has again decided to buy a DSP-30 static pulverizer from Demarec, a member of the Kinshofer Group. “Back in 2012 we had already invested in a Demarec pulverizer. Seven years of trouble-free operation made it easy for us to choose a replacement.”
The directors Wim Bouw and Jan van de Kraats about their latest investment in the Demarec DSP pulverizer:
“We are simply happy with the quality of the Demarec pulverizers. They have a very compact design, a high performance and exchangeable wear parts. The contact with the Demarec employees is also great. That is very important for us when doing business together. After seven years of work with our old Demarec pulverizer, we thought it would be time to get a new one, although the old is still working perfectly.”

This time, the company Van de Kraats and Bouw chose the Extreme-version of the DSP-30. It is equipped with the patented DemaPower-System 2.0. This unique cylinder technique has been developed by the Demarec engineers. The DemaPower-System possesses a double-acting differential technology, resulting in extremely fast cycle times oft he pulverizer. The jaws open and close within 5 seconds only.

Furthermore, the cylinder achieves up to 20% more power then conventional cylinders thanks to the use of 4 pressure chambers. This results in an enormous performance increase during work that can reach up to 30%. Demarec is always a very economic solution.

It is unique with all Demarec pulverizers, that upper and lower jaw are constructed completely with exchangeable wear part. Welding works are almost unnecessary, and the base material is mainly protected from fatigue. The mobile jaw is equipped with an exchangeable base tooth plate, which again hast wo exchangeable teeth. The fixed jaw is equipped with exchangeable scraper teeth. The covers in the fixed jaw are not only exchangeable but can also be turned. Demarec pulverizers have very low operating costs.

Wim Bouw: “The fact, that Demarec pulverizers have so many exchangeable wear parts, was crucial for the decision to buy.”

Van de Kraats en Bouw B.V. was founded 52 years ago and its 10 employees are working in demolition, recycling and trade of used construction materials – always focusing on quality and safety.

The company is based at Kievitsmeent in Ede, Holland.

Jan van de Kraats: “Our fleet includes a mobile screener, different trucks and pick-ups, three buckets and an excavator with the Demarec DSP-30-Extreme pulverizer. We often also rent out additional machinery.“

The office is responsible for the daily administative work like e.g. the calculation and planning of demolition jobs. Futhermore, the waste recycling is also coordinated from there.
Wim Bouw: “Our clients are mainly demolition colleagues, the government and companies from the area Ede, Utrecht, Apeldoorn and Anrhem. Our vision for the future is not so much growth, but to keep the quality of our service consistent.”
