Embodiment Construction

[0024] The sieve shown in Figure 1 is made of alumina ceramic material as a whole, which is made of 95% alumina powder, plus an appropriate amount of additives, and is molded and sintered. Silicon nitride ceramics, fused-cast chromium corundum ceramics, and zircon ceramics can also be used. , silicon carbide and silicon carbide fiber reinforced alumina and other materials are made of higher strength, more wear-resistant, more heat-resistant ceramic screen. The shape of the ceramic sieve is a square sheet, and the sieve surface is provided with 16 truncated pyramid-shaped sieve holes 2 of the same size arranged vertically and horizontally. Horizontal grid 6, establishes four installation press platforms 4 on four corners, and the end face of installation press platform 4 is the cambered surface that is compatible with compression bolt and washer. This structural sieve is suitable for installation on a flat combined sieve plate or directly on the bottom frame of the vibrating sc...

Abstract

The screen deck for sieving apparatus is made of ceramic material or comprises one ceramic surface layer and one bottom reinforcing layer. The screen deck has screen holes in certain geometric shape. The present invention also discloses one kind of combined screen plate with screen decks assembled onto the frame. The screen plate has high wear resistance, low cost, long service life and capacity of local replacement, and is used in different kinds of industrial sieving apparatus.

Description

technical field [0001] The invention relates to a sorting device, in particular to a sieve piece of ceramic material used for the sieve surface of the sieving equipment used for sorting solid particle materials. The invention also relates to a combined sieve plate formed by the sieve piece. Background technique [0002] Screening equipment has long been used as the main equipment for sorting granular materials in industrial production. It is widely used in mining, metallurgy, building materials, and chemical industries. The screen surface of the screening equipment is the part that directly carries the sorted materials and directly bears the impact and friction of materials. Even high-temperature corrosion, harsh operating conditions, and the key component to complete the screening function, its wear resistance directly affects the efficiency and cost of the sorting operation, especially when screening high-temperature materials, the ordinary metal screen surface has poor wea...
