Vibrates the feeding engine in the production process, may massive, the granulated material from store in the bunker even, fixed time, to give continuously is expected in the installment, may evenly feed the material continuously in the sand and crushed stone production line for the stave machinery, and carries on the coarse fraction to the material, vibrates the feeding engine widely to use in professions and so on metallurgy, coal mine, dressing, building materials, chemical industry, grinding compound stave, in the screening combination plant
振動給料機在生產流程中，可把塊狀、顆粒狀物料從貯料倉中均勻、定時、連續地給到受料裝置中去，在砂石生產線中可為破碎機械連續均勻地喂料，並對物料進行粗篩分，振動給料機廣泛用於冶金、煤礦、選礦、建材、化工、磨料等行業的破碎、篩分聯合設備中 -
Coarse grained soil is composed of sand and gravel, stone residual, blasted stones etc., which has a characters of less cohesive force among grains and strong ability of water penetration. it is a kind of soil of loose grain structure with better utilization properties in the engineering
粗粒土是指砂礫石、砂卵石、石渣、爆破開採的石料等粗顆粒土石混合料，具有粗顆粒間粘結力小、透水性強的性質，是一種鬆散的顆粒狀結構，具有良好的工程使用性能。 -
Firstly, the environment harm of the waste rock is studied ; secondly, we research the physics and mechanics property of the waste rock of the dabagou tunnel and get the physics and mechanics property index of waste rock ; thirdly, after comminuting the waste rock and compounding concrete as coarse aggregate, we make the comparison between it and the songshan stone in the fuxin building market at present, it proves to possess extension application value ; fourthly, on the foundation of it, we utilize waste rock as coarse aggregate to compound high strength concrete, steel fiber high strength concrete, polymer cement concrete, asphalt concrete by uniform design and research their mechanics property index by experiment
首先闡述了排矸石對環境產生的危害，其次對大巴溝隧道排矸石的物理力學性質進行了試驗研究，獲得了排矸石的物理力學性能指標。將排矸石粉碎后，作為粗骨料配製成混凝土，與目前阜新建築市場上所用的松山石子進行比較，證明其具有推廣應用價值。在此基礎上，利用均勻設計法，將排矸石作為粗骨料配製成高強混凝土，鋼纖維高強混凝土，聚合物水泥混凝土，瀝青混凝土，通過試驗測定其力學指標，獲得了各種排矸石混凝土的優化方程和最佳配合比。
