8/1/2019 Jaw Crusher, also known as concrete crusher, is usually used as the primary equipment for concrete crushing. It is also suitable for metallurgy, mining, construction, chemical, water conservancy and railway sectors, and used as a device for fine and medium crushing of ores and rocks with compressive strength below 250 Mpa.[email protected]
The effect of stone dust deposition on the rate of transpiration in Shorea robusta was studied in three principal seasons in a polluted forest in comparison to an almost non-polluted forest. The extent of particulate pollution was determined by measuring suspended particulate matter in the air and dust fall on leaf surface. Macroscopic and microscopic leaf injury symptoms were studied.

Chemical analyses of dust were done to check on the toxicity of dust from the quarry, so as to predict its pos-sible impacts on human health and the environment. A Casella dust sampler and a GPS were used to collect dust onto the filters and to mark the sampling points respec-tively . 3. Results
3/24/2020 Introduction of sand and gravel production line. The river stones are uniformly sent to the PE600×750 jaw crusher by the vibrating feeder for coarse crushing into 65-160mm size. And then the coarsely crushed material is sent to the PSG900 cone crusher by the belt conveyor for secondary crushing into 13-38mm, then is fed into the sand maker for further crushing.
It can effectively reduce the dust discharging and make the dust pollution be the least one. Function of spray water dust suppression device There are many factors affecting the dust producing in the mineral ore raw materials stocking, taking, transporting process, such as the particle distribution, moisture content, air humidity, wind speed, material flow and fall and so on.
