Dust pollution is an important feature of the production of traditional large-scale mixer equipment. In the past, people did not pay much attention to environmental protection. In the case of large demand for concrete in the market, traditional large-scale concrete mixer equipment is widely used in the market with its high efficiency production mode. With more and more serious environmental problems, environmental protection has been put on the agenda. The state and government departments propose to give consideration to environmental protection while developing economy, so as to achieve harmonious development with the environment.

扬尘污染是混凝土搅拌机常见的环境污染，砂石、水泥的运输、堆放、上料以及卸料过程中都会产生扬尘污染，因此，原材料在上料、配料、搅拌设备都必须实现全封闭，搅拌主机也要配置吸尘装置，定期更换和保养。

Dust pollution is a common environmental pollution of concrete mixer. Dust pollution will be produced in the process of transportation, stacking, loading and unloading of sand, stone and cement. Therefore, the raw materials must be completely closed in the feeding, batching and mixing equipment. The mixing host should also be equipped with dust suction device, and be replaced and maintained regularly.
             

混凝土搅拌机的骨料配料仓应采取封闭式筒仓；布设在密闭搅拌楼外的粉料筒仓及骨料简仓必须配置除尘设施，且有专人管理，定时清洁，确保除尘设施正常运行;粉料简仓上料口应配备密闭防尘设施，上料过程应有专人监控，防止粉料泄漏。

The aggregate batching silo of concrete mixer shall adopt closed silo; the powder silo and aggregate silo arranged outside the closed mixing building must be equipped with dust removal facilities, which shall be managed by special personnel and cleaned regularly to ensure the normal operation of dust removal facilities; the feeding port of powder silo shall be equipped with closed dust prevention facilities, and the feeding process shall be monitored by special personnel to prevent powder leakage.

混凝土搅拌机的骨料输送带必须全密闭，运行时不得有通往大气的出口，杜绝骨料输送过程中出现粉尘外泄。

The aggregate conveyor belt of concrete mixer must be fully closed, and there shall be no outlet to the atmosphere during operation, so as to prevent dust leakage during aggregate transportation.

混凝土搅拌机原材料堆码场除车辆进出口外设置了围挡、顶棚等封闭式，实现原材料装卸、装运、配料在室内完成；原材料堆码场车辆进出口和卸料区配置喷淋设施降尘等装置，并有专人负责管理；尽量避免现场破碎石料和筛分砂石，若确需现场作业，应在全密闭的厂房内完成，并配置喷淋设施降尘或负压收尘等装置。

In addition to the vehicle entrance and exit, the concrete mixer raw material stacking yard is equipped with enclosure, ceiling and other closed type, so that the loading and unloading, loading and batching of raw materials can be completed indoors; the vehicle entrance and exit and unloading area of the raw material stacking yard are equipped with spraying facilities, dust reduction devices and other devices, and special personnel are responsible for the management; try to avoid crushing stone and screening sand and stone on site, if it is necessary to work on site, it should be fully closed And equipped with spray facilities or negative pressure dust collection devices.

传统大型混凝土搅拌机设备粉尘污染严重、污水处理不合格以严重危害人们生存环境，为避免被市场所淘汰，传统搅拌机需大力进行改造，解决好粉尘污染及污水排放问题。而对于大型搅拌机行业来说，产品除了要突出强大的生产能力外，环保节能、智能化水平也需要得到体现，这也是搅拌机设备多元化发展、突破传统发展瓶颈的根本问题。

The traditional large-scale concrete mixer equipment has serious dust pollution and unqualified sewage treatment, which seriously endangers people's living environment. In order to avoid being eliminated by the market, the traditional mixer needs to be vigorously transformed to solve the problems of dust pollution and sewage discharge. For the large mixer industry, in addition to highlighting the strong production capacity, the environmental protection, energy saving and intelligent level also need to be reflected, which is also the fundamental problem of the diversified development of mixer equipment and breaking through the traditional development bottleneck.
