The crusher's body is made from welded carbonated steel sheets. Inside the body, there is a shaft with two discs with attached hammers. On the inside, the crusher is lined with abrasion-resistant material; additionally, grate bars can be installed at the bottom. The space between grate bars is individually set. They allow for the already crushed material of a given maximum granulation to traverse downward. Due to high wear and tear, the hammers, grates and linings are made from abrasion-resistant material.
