The conveyor vibrating screen is extensive applied straightly in the metallurgy, building materials, chemical engineering, refractor, cement, ceramic, food, mine mountain, coal, building materials, electrical power...etc. every trade inside, used for the operation of graduation to differ the degree to every kind of material. Vibration conveyor mesh porous face is to use the vibration mixing of different particle size material according to particle size grading machine, form basic divided into type and type two kinds. Normally with a type is most common, with eccentric block or eccentric shaft vibration source, the mixture of the two source is relatively common. DSZ - 40800 type vibrating conveyer sieve is a clean sand in lost foam casting equipment, waste residues, dust in through impassability specifications and mesh will get the right material according to particle size grading and sand. It USES a vibration motor drive, simple structure, superior performance, it in high efficiency, large output, sieve surface blocking. KEY WORDS：conveyor vibrating screen，casting sand，Lost Foam casting 目 录 1.1 1 摘 要 I Abstract II 第一章 绪论 1 1.1 毕业设计的目的 1 1.2 设计任务 1 1.3 设计背景及意义 1 1.4 振动机械的分类 3 1.5 振动筛优点及适用范围 5 1.6 国外研究现状 5 1.7 国内研究现状 6 1.8 发展趋势和方向 7 第二章 消失模砂处理系统的作用和设备组成 9 2.1 概述 9 2.2 砂处理系统的作用 9 2.3 砂处理常用设备 9 第三章 振动筛的工作原理及结构组成 13 3.1 振动筛的用途及要求 13 3.2 振动筛工作原理 13 3.3 振动筛的构造 13 3.3.1 激振器
