As a pure natural stone in nature, pebbles are mostly found in rivers and hilly areas and are easy to mine. As an important building aggregate, cobblestone can become high-quality sand after crushing, sand making, and screening. The sand made from cobblestone has uniform particle size, good wear resistance, and low mud content. It is a good material for sand making. However, as the form of environmental protection has become more and more severe in recent years, the environmental protection problem of sand making machines has attracted more and more attention. So, what is the criterion for judging the environmental protection of a sand making machine? What are the environmentally friendly sand making machines?
The environmental protection effect of the cobblestone sand making machine is mainly manifested in two aspects in production. One is low noise, and the other is low dust pollution. Therefore, when judging its environmental protection effect, it needs to be carried out from these two aspects, mainly as follows:
1. When the pebble sand making machine is in use, its start-up noise and running noise must meet the noise emission standard, so as to meet the requirements of environmental protection.
2. When the cobblestone sand making machine is in use, the dust pollution is small. When the machine is tested, this demand is difficult to judge, but we can judge its structure. Generally speaking, it is mainly based on its exhaust. The air system and whether it is equipped with a dust collector to determine the dust emission, if the exhaust system is good and the dust removal equipment is advanced, the dust pollution in the production will be relatively low.
What is the environmental protection sand making equipment for cobblestone?
1. PLS series vertical impact crusher
The new generation of sand making equipment is very cost-effective, and it is one of the most popular equipment on the market. The advantage is that the sand making effect is very good, and the efficiency is very high. It has the dual functions of sand making and shaping, and adopts deep cavity impeller design. It can increase the stone throughput by more than 30%, and the equipment has a sealed cavity design to reduce the impact of dust and noise, and truly achieve green environmental protection.
2. PFL series vertical complex crusher
The complex crusher is also called vertical crusher. It has efficient crushing capacity for limestone and is also widely used in machine-made sand and metal ores. It is ultra-fine crushing equipment with simple structure and mostly cubic finished products. It is suitable for crushing medium-hard and extra-hard materials, and is not affected by the moisture of the material, and the moisture content can reach about 8%. The product is cubic, with high bulk density and minimal iron pollution.
3. PLK series vertical shaft impact crusher
Vertical shaft impact crusher, also known as sand making machine, is domestic, international and leading level high-efficiency stone crushing equipment developed in accordance with the actual situation of domestic sand production. The PLK series vertical shaft impact crusher produced by Luoyang Dahua Heavy Industry Technology Co., Ltd. is mainly used for stone crushing in the building materials industry, road and railway construction and other industries that apply stone. It has a unique structure, simple operation, high efficiency and energy saving, and product granularity, good cost-saving and other features.
Add dust removal and noise reduction system to the sand making machine equipment manufacturing: reserve and install various specifications of dust removal and noise reduction equipment, real-time and effective control of the dust emission and noise release of the sand making machine, which is more environmentally friendly.
