Description

Material moving hammer for crusher or crusher, crusher and crusher Technical Field The utility model relates to the technical field of hammer element structures for crushers or crushers, in particular to a material moving hammer for crushers or crushers. In addition, the utility model also relates to a crusher or a crusher comprising the material moving hammer. Background Crushers and crushers are equipment commonly used in industrial production mainly for reducing bulk material to smaller particle sizes. Can be widely applied to the industries of chemical engineering, metallurgy, building materials, mines and the like. A crusher is an apparatus for reducing bulk material to smaller particle sizes. Crushing modes of the crusher include extrusion, splitting, breaking, shearing, impacting or beating, and the like, and are usually mixed by multiple modes of action. Crushers can be classified into coarse crushers, medium crushers and fine crushers according to the feed and the particle size of the product. A pulverizer is a device that pulverizes a material into fine particles by mechanical force. It mainly comprises three parts of a crushing mechanism, a transmission mechanism and a motor. The working principle of the pulverizer is based on the principle of crushing mechanics, impact force, shearing force, crushing force and the like are applied to materials through a mechanical device, and the binding force among molecules in the materials is destroyed, so that the materials are loosened and are easy to crush. The structural design of the pulverizer directly influences the pulverizing effect. In crushers or crushers, a transfer hammer (also called a hammer head) is a key component which generates violent impact, shearing and grinding actions on the material by rotating at high speed, crushing or crushing the material. The design and arrangement mode of the material moving hammer directly influence the crushing or crushing efficiency and the service life of the hammer head. The other function of the material moving hammer in the crusher or the pulverizer is to push the materials to pass through the crushing cavity or the pulverizing cavity, and crush or pulverize the materials, so that the refinement and classification of the materials are finally realized. The existing material moving hammer has the following problems: 1. The material moving hammer is worn after long-time working and needs to be replaced regularly, which increases the operation cost. 2. The hammer may break due to iron pieces entrained in the ore, improper control of chemical composition or improper heat treatment process. Disclosure of utility model The utility model provides a material moving hammer for a crusher or a crusher, the crusher and the crusher, and the hard alloy blocks are embedded in a hammer body, so that the structure of the hammer body and the design of a crushing surface are optimized, the wear resistance is improved, the fracture risk is reduced, the crushing effect is optimized, the service life is prolonged, and meanwhile, the operation safety is improved, and the technical problems that the conventional material moving hammer is easy to wear and fracture, high in cost and low in efficiency are solved. According to one aspect of the utility model, a material moving hammer for a crusher or a crusher is provided, and the material moving hammer comprises a hammer body, wherein a shaft hole is formed in the hammer body, the hammer body is provided with a material moving surface and a crushing surface, the material moving surface is arranged at the lateral direction of the hammer body, the crushing surface is arranged at the end part of the hammer body, the material moving surface is arranged in contact with the crushing surface, a hard alloy block is embedded in a matrix of the hammer body, and the hard alloy block is arranged close to the material moving surface.
