Embodiment Construction

[0025] Such as figure 1 As shown, the crushing roller of the present invention includes a roller base 1, on which a metal body 2 having a hardness different from that of the roller base 1 is arranged, and the metal body 2 on the roller base 1 is formed on the roller base 1 Slotted inlays evenly spaced around the circumference (see figure 1 ) or inserts (not shown) or columnar inserts (see Figure 4 , Figure 5 ).

[0026] The inlaid metal body 2 can also be distributed on the roller base 1 in a V shape, such as figure 2 As shown, or the inlaid metal body 2 is distributed on the roller base 1 in a zigzag shape, such as image 3 shown.

[0027] The roller base is made of high-hardness, high-wear-resisting alloy obtained by casting and heat-treating one of high-chromium alloy, high-manganese alloy, high-tungsten alloy, high-vanadium alloy, multi-element alloy steel, high-carbon steel, and white cast iron. The metal body adopts one of medium and low carbon steel, low alloy,...

Abstract

The invention discloses a crushing roller of a roller type high-frequency vibration crusher and a manufacturing method thereof. The crushing roller comprises a roller base body. The crushing roller is characterized in that the roller base body is provided with a metal body which is different from the roller base body in hardness. The roller base body of the crushing roller is provided with the metal body which is different from the roller base body in the hardness so that an invisible tooth roller is formed; in the use process, the metal body and the roller base body have the hardness difference and have different wear resistances; and the metal body and the roller base body are subjected to different abrasions to naturally form tooth shapes from an invisible tooth shape to a visible tooth shape; and the tooth shapes are kept all the time in the roller abrasion process and the aims of not sliding and having a fine crushing effect are achieved in the process of crushing materials.

Description

technical field [0001] The invention belongs to crushing equipment, in particular to a crushing roller of a roller-type high-frequency vibration crusher and a manufacturing method thereof. Background technique [0002] Roller crusher is widely used as medium and fine crushing equipment in non-ferrous metal ore and non-metallic ore processing, building materials and other industries due to its simple structure, light weight, reliable operation, low price, uniform product size, and less over-crushing phenomenon. middle. The crushing drum is the key component in the roller crusher. Because the existing crushing roller adopts the same homogeneous material, the material is easy to slip when crushed on the roller surface, resulting in fast wear, low efficiency, and uneven crushing particle size. Contents of the invention [0003] The object of the present invention is to propose a crushing roller of a roller-type high-frequency vibration crusher and a manufacturing method ther...
