Embodiment 1

[0029] The sand casting method of the ceramic composite cone crusher liner includes:

[0030] Step 1: Prepare ceramic blocks. The pottery is divided into cylindrical ceramic block 3 with a diameter of 15-25 mm and a length of 15-50 mm or a frustum-shaped ceramic block 3 with a diameter of 18-25 mm at a large end and a diameter of 15-23 mm at a small end and a length of 15-50 mm. Select stainless steel welding wire to weld steel nails on one of the bottom surfaces of the cylindrical ceramic block 3 or the small bottom surface of the round table ceramic block 3, then polish and clean the ceramic block 3, and apply nickel on the surface of the ceramic block 3: borax: water weight ratio is 1: 4:5 nickel-containing supersaturated borax solution, adding nickel powder to borax can improve the wettability between the molten metal and the ceramic block 3, increase the fluidity of the molten metal on the ceramic block 3, and make the wall of the mortar 1 and broken A good metallurgical...

Embodiment 2

[0036] The lost foam casting method can also be used to complete the preparation of the ceramic composite cone crusher liner. It differs from the sand casting method in that: when preparing the sand mold, a hole matching the ceramic block 3 is excavated at the position where the ceramic block 3 is distributed in the liner foam plastic model, and the ceramic block 3 is placed in the hole; there is no need to adjust the sand during casting. The box is preheated, and the molten metal is directly poured into the sand box.

[0037] The tensile strength Rm of the ceramic composite cone crusher liner produced by the above-mentioned preparation method of the ceramic composite cone crusher liner is ≥ 735 MPa, the yield strength Re ≥ 440 MPa, the elongation after breaking A ≥ 15%, and the reduction of area Z ≥ 15 %, impact toughness Aku≥180J / cm 2 , Rockwell hardness is 65HRC.

[0038] Therefore, the present invention adopts the preparation method of the above-mentioned ceramic composi...

Abstract

The invention discloses a liner plate of a ceramic composite cone crusher, which comprises a rolling mortar wall, a crushing wall and a ceramic block. The ceramic block is inlaid and cast on the inner surface of the rolling mortar wall and the outer surface of the crushing wall. The surface of the ceramic block close to the crushing cavity is in the same plane as the inner surface of the mortar wall and the outer surface of the crushing wall, and the ceramic block is metallurgically bonded to the mortar wall and the crushing wall. The preparation process of the ceramic composite cone crusher liner is: preparation of ceramic blocks - preparation of sand molds - casting - boxing - heat treatment. The composite liner produced by the method for preparing the ceramic composite cone crusher liner in the present invention has the advantages of long service life, high hardness, good wear resistance and impact resistance.

Description

technical field [0001] The invention belongs to the technical field of cone crushers, and in particular relates to a preparation method of a ceramic composite cone crusher liner. Background technique [0002] The cone crusher liner is the main part of the cone crusher used for crushing ore, which is composed of the rolling mortar wall and the crushing wall. When the crusher is working, the motor drives the eccentric shaft sleeve to rotate, and the axis line of the crusher performs a pendulum motion under the force of the eccentric shaft sleeve, so that the surface of the crushing wall sometimes approaches and sometimes leaves the surface of the rolling mortar wall, so that the ore is crushed The crushing cavity formed by the wall and the wall of the rolling socket is continuously squeezed and bent to be crushed. The liner of the cone crusher is prone to severe wear due to frequent strong impacts, resulting in uneven particle size, decreased production efficiency, and increa...
