чертеж цементной мельницы Kai Hing mine machine combined construction waste crushing plant and crusher construction waste and asphalt concrete pave the way Kai Hing mine machine combined construction waste crushing plant and crusher construction waste and asphalt concrete pave the wayResurfacing asphalt concrete road in front, often due to the dismantling of the old road surface to produce large amounts of waste asphalt concrete. Developed countries each year due to theчертеж цементной мельницы removal of road surface to produce a lot of waste asphalt concrete, its recycling has become one of the waste material is used as the main part of the building materials. China with the development of highway construction, the annual number of generated waste asphalt concrete has increased year by year. Waste asphalt concrete can be recycled as a building material for paving a new asphalt concrete pavement.Recovery methods Leng Rong recovery and hot melt recycling.The former is the crushed waste asphalt concrete Leng Rong shop on the lower deck, on which the laying of new asphalt concrete pavement; latter grinding waste asphalt concrete as part of aggregate mixed with new asphalt concrete, made recycled asphalt concrete. Incorporation of waste asphalt concrete up to 15% to 50% (by weight). Quality and the impact of the incorporation of the quality of the recycled asphalt concrete by waste asphalt concrete waste asphalt concrete, the better the quality, the greконструкция вибропитателяater the proportion of incorporation. Containing the excessive deterioration asphalt recycled aggregate can not be used in the manufacture of recycled asphalt concrete.Prepared by heating the recycled asphalt concrete hybrid method and apparatus are as follows:(1) raw aggregate and new aggregate mixed together heated, or various types of aggregates were heated to the same temperature before mixing. Achieve the heating apparatus of a mixed manner, there are two, one is the cylindrical dry mixing machinery, recycled aggregate and the new aggregate input from the combustion chamber side of the cylinder. Another batch-type mixing machine, the recycled aggregate and new aggregates were dried by heating (or the use of a two-layer structure of the dryer), the new aggregate input from the combustion chamber side, recycled aggregate is added by the middle of the drum.(2) recycled aggregate or pre-heating of recycled aggregate at room temperature and heated to high temperatures, new aggregatсреднее дроблениеes are mixed and heated together with a mixer. The heating method is to use more batch-type heating and mixing machine, heated batch-type mixing machine, such as shown, for heating the recycled aggregate at room temperature then mixed with the new aggregate after the high-temperature heating heat, recycled aggregate pre heat to a certain degree, and then heated together in mixed manner.Either way the temperature of the asphalt heat must be controlled so that it does not degenerate and to ensure adequate mixing of raw materials. In addition, recycled asphalt concrete construction methods and ordinary asphalt concrete, so demolition waste recycled asphalt concrete block can also be recycled asphalt concrete pavement after repeated use as recycled aggregate.Add your comment
