Embodiment Construction

[0026] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0027] see Figure 1 to Figure 4 shown.

[0028] A kind of crusher for shaping needle flake sandstone of the present invention, comprises: casing cover 1, shaping rolling body 2, the rotatable gap of shaping rolling body 2 is installed in the hollow interior of casing cover 1, and casing cover 1. A plurality of spaced crushing grooves 11 are arranged on the side wall;

[0029] After crushing, the needle-shaped sandstone is brought into the shaping chute 21 on the rotating shaping roller body 2 for spiral rotation, and the finely crushed sandstone falls from the gap between the shaping roller body 2 and the casing cover 1, The elongated needle-shaped sandstone enters the shaping chute 21 and is crushed and shaped for the first time. After elastic deformation and shaping, the needle-shaped sandstone enters the shaping chute 21 and ...

Abstract

The invention discloses a construction process for shaping needle-sheet-shaped gravel. The construction process for shaping the needle-sheet-shaped gravel uses a crusher for shaping the needle-sheet-shaped gravel and comprises the following steps that 2, processed needle-sheet-shaped gravel is conveyed into a machine shell cover through a conveying belt, and a shaping rotary rolling body rotates anticlockwise under the stable supporting action of a bearing as shown in the figure, the rotating speed of the shaping rotary rolling body is 600-780 r / min, the long-strip-shaped needle-sheet-shaped gravel is crushed and shaped for the first time when entering a shaping material sliding groove, the needle-sheet-shaped gravel subjected to elastic deformation and shaping enters the shaping material sliding groove, and when being driven to a crushing groove formed in the axial direction of the machine shell cover, the middle of the needle-sheet-shaped gravel subjected to elastic deformation is released in the crushing groove to complete crushing, and secondary crushing and shaping are completed. The construction process for shaping the needle-sheet-shaped gravel ensures that the needle-sheet-shaped gravel are changed into oblate and square-round shape, the content of the needle-sheet-shaped gravel is reduced to 6% after machining is completed, the problem that secondary machining is needed due to the fact that the content of the needle-sheet-shaped gravel exceeds the standard is solved, and the yield is improved by 3%.

Description

technical field [0001] The invention relates to a construction technique for shaping needle-shaped sand and gravel, and belongs to the technical field of sand and gravel production. Background technique [0002] Basalt has the advantages of compact structure, high strength and stability, hard rock, strong compressive resistance, low crushing value, strong corrosion resistance, wear resistance, low draft, poor electrical conductivity, and asphalt adhesion. , is the best cornerstone for the development of railway transportation and road transportation High-quality sand and gravel raw materials, the quality fully meets the sand and gravel material standards for construction and road laying; [0003] Basalt with a particle size of 9-16 mm is used as the main skeleton material of asphalt concrete road fabric, which has the advantages of wear resistance, noise reduction, dust absorption, and good asphalt adhesion, and has been widely used in modern road construction; With the inc...
