Description

Ore crushing device

Technical Field

The utility model relates to the technical field of calcium carbonate production and processing, in particular to an ore crushing device.

Background

Calcium carbonate is the main component of materials such as limestone, marble, calcite and the like, so the preparation of the calcium carbonate is mainly realized by throwing ores of the materials such as marble, calcite and the like into a jaw crusher for crushing into sand materials during the preparation of carbon, and then grinding the sand materials into fine powder through a grinder.

The jaw crusher is easy to generate the phenomena of returning materials and blocking materials in the using process, the returning materials refer to the phenomenon that ores fly out from a feeding hole in the crushing process, mainly because the equipment is produced in an irregular way, the materials are subjected to upward force and insufficient friction force when crushed, the materials are stressed and fly out upwards, the size of a discharging hole is overlarge, the abrasion of a movable jaw and a fixed jaw is serious, the size difference of the materials is large, and the like, therefore, part of manufacturers can weld protection plates at the position of the discharging hole, so that the potential safety hazards to surrounding personnel and equipment caused by the material fly out during returning materials are avoided.

Although the material flies out when can effectively avoiding returning charge through welding the guard plate, still there is returning charge phenomenon, consequently the guard plate is inside after using for a long time because the striking number of times that withstands is too much, leads to the guard plate to appear local fracture, local uplift phenomenon etc. and the material still can fly out when the continuous use is most likely to lead to the guard plate to fracture and lead to returning charge, and guard plate welded fastening and breaker feed inlet, the operation is very loaded down with trivial details when dismantling and installing, need cut the welding seam at present and polish the welding face again and level, later with new guard plate welded fastening.
