Blade plate for crusher and crusher

A blade plate for crushers to be installed on a fixed side, comprising a base material part and a plurality of blade parts arranged on a surface of the base material part,

• wherein the blade part comprises:
• a concave blade part arranged on an upper side of the base material part;
• a diamond blade part arranged on a lower side of the concave blade part and having an edge formed of a corner between a belt part and an inclined part;
• a chevron blade part which is configured in a polyhedral shape having an edge formed of a corner between a cross-shaped tip end belt part and a foot part and an edge formed of a corner between an inclined belt part and a foot part, and which is bound to an intersection place of diagonal lines of the diamond blade part;
• and
• a convex blade part having an edge formed of a corner between a belt part and an inclined part, the convex blade part being connected to a part of the chevron blade arranged on the lowermost stage of the base material part.

A crusher comprising:

• a vertically-opening frame which is composed of a pair of side frames provided in juxtaposition, a front frame connecting front sides of both the side frames and a rear frame connecting rear sides of both the side frames, and which has an upper opening part for injecting a material to be crushed and a lower opening part for discharging the crushed material;
• a fixed blade plate which is fixed and supported on a holder provided vertically or slantly to the frame;
• and
• a moving blade plate which is axially supported on a fulcrum shaft constructed between both the side frames, is inclined to the frame at a backward movement limit position, becomes vertical to the frame at a forward movement limit position, and moves forward and backward using the fulcrum shaft as a fulcrum in accordance with the forward and backward movement of a piston rod of a cylinder provided on the rear frame,
• wherein the material to be crushed is supplied to a V-shaped crushing space formed between the fixed blade plate and the moving blade plate, and is crushed upon forward movement of the moving blade plate to the fixed blade plate,
• wherein one or both of the fixed blade plate and the moving blade plate further comprise a diamond blade part having an edge formed of a corner between a belt part and an inclined part;
• and
• a chevron blade part which is configured in a polyhedral shape having an edge formed of a corner between a cross-shaped tip end belt part and a foot part and an edge formed of a corner between an inclined belt part and a foot part, and which is bound to an intersection place of diagonal lines of the diamond blade part.
