Process for producing a particulate recyclate from quartz composite

A process for producing a particulate recyclate from quartz composite, comprising the steps of:

• comminuting quartz composite moldings composed of a polymer matrix with inorganic and/or organic filler particles embedded therein, in which precomminuted pieces of molding are comminuted in a hammer mill to form particles that form the recyclate;
• removing a first particle fraction, using a sieve, having a maximum grain size greater than a target grain size of the particles that form the recyclate from the hammer mill;
• and then, in a downstream sieving device, removing, from the first particle fraction, a second particle fraction containing particles having a grain size equal to or less than the target grain size that form the recyclate and separating out a third particle fraction containing particles larger than the target grain size.
