Problems solved by technology

This causes the surfaces of the crushing elements to wear relatively quickly and necessitates maintenance or replacement of the crushing elements
However, the use of harder and thus less abrasive materials leads to a reduction in the elongation at break as well, which leads to the failure of the crushing elements for uncrushable objects in the crushing chamber

Embodiment Construction

[0032] figure 1 A crusher 10 , in particular a gyratory crusher 10 , is shown with a movable crushing element, the crushing cone 12 , and a stationary crushing element, the crusher housing 14 . For the sake of simplification, for example, the drives, supports and funds of the gyratory crusher 10 are not shown. The gyratory crusher 10 is designed substantially rotationally symmetrically, the crusher housing 14 having the shape of a hollow cone and the crushing cone 12 is arranged in the hollow-conical crusher housing 14 . The crusher housing 14 has a feed area 16 into which the material to be shredded is fed. The feed area 16 is arranged on the upper side of the gyratory crusher 10 , and the crusher housing 14 has the largest diameter at the feed area 16 . The crusher housing 14 tapers in the axial direction from top to bottom, so that the lower region of the crusher housing 14 has the smallest diameter. The lower region of the crusher housing 14 forms an outlet 18 through w...

Abstract

The invention relates to a breaker (10 for comminuting material, comprising a breaking chamber (20) having a loading area (16), into which material to be comminuted is loaded, and a breaking gap (22)for breaking the material, wherein the breaking chamber (20) tapers from the loading area (16) to the breaking gap (22), wherein the breaker (10) has a stationary breaking element (14) and a movable breaking element (12), which delimit the breaking chamber (20), and wherein the stationary breaking element (14) has a wear-protection element (24), which is formed from a metal matrix composite material having a wear-protection inlay (30) made of a hard metal and / or of ceramic. The invention further relates to a method for producing a wear-protection element (24) of a stationary breaking element (14) of a breaker (10), comprising the steps: positioning a wear-protection inlay (30) made of a hard metal or ceramic in a casting mould for casting the wear-protection element (24), and casting the wear-protection element (24), such that the wear-protection inlay (30) is at least partly enclosed by the cast material of the wear-protection element (24).

Description

technical field [0001] The invention relates to a crusher having a stationary crushing element and a movable crushing element, wherein the stationary crushing element comprises a wear element. Furthermore, the invention relates to a method for manufacturing a wear element of a stationary crushing element of a crusher. Background technique [0002] Crushers, in particular gyratory crushers, jaw crushers, cone crushers or jaw crushers, are often used for comminuting materials such as limestone, oil shale, clay, oil sands or similar mineral materials. One such cone crusher is known from WO 2014 / 187713 A1. [0003] A crusher, such as a gyratory crusher, jaw gyratory crusher, cone crusher or jaw crusher, has a crushing chamber defined by stationary crushing elements and movable crushing elements. The movable crushing element is rotationally driven eccentrically so that the crushing gap increases and decreases periodically. The crushing elements usually consist of wear-resistan...
