Primary Crusher

Machine suitable to crush and crumble large lumps of hard shale clay; it can be placed either directly under box feeders or under hoppers used to unload from motor vehicles.

The primary crusher is made of two strong sides in steel construction, where are placed the housings of the bearings that support two rollers placed at a fix distance between the centers and rotate at the same speed. These rollers consist of a shaft on which are assembled some multi-tip crushing stars made of steel, with coatings against wear on the same tips.

The granulometry of the material that comes out grants the good running of the machines downstream. The rollers are actioned by means of epycïcloidal reduction units driven by a system of motors, pulleys and v-belts. A strong hopper in electro welded plate conveys the clay to some crushing discs and support, at the same time, a set of scrapers for the cleaning of the rollers. The side walls of this hopper are protected by a wear proof plate. All the bearings are lubricate with grease.
