Sludge is the sediment, particulate matter, and floating matter produced when wastewater is treated by physical, chemical, physicochemical, and biological methods. Sludge generally refers to a thick substance between liquid and solid, which can be pumped, but it is difficult to separate solid and liquid by settling. Sludge dryer is a very mature drying and drying equipment produced by mining equipment manufacturers, suitable for drying sludge, magnetic, heavy and floating concentrates of metal and non-metallic mines and clay of cement industry and many other industries. Sludge dryer is suitable for urban sludge drying. The drying of sludge makes it possible to use sludge for agricultural purposes, as a fuel, for incineration and even for the reduction of landfill sites.

The price of sludge dryer varies in the market, because the price of sludge dryer is mainly affected by the following factors:

First, the price of steel affects the price of equipment. The main raw material of sludge dryer is steel, steel price changes will inevitably affect the price of sludge dryer changes, in addition to China's regional economic disparity is relatively large, the price of steel in various regions are different, so the price of sludge dryer is also different.

Secondly, sludge dryer production costs affect the price. Different sludge dryer manufacturers to produce sludge dryer input manpower, material and financial resources are different, general input production technology is more sludge dryer manufacturers, the production of sludge dryer technology content is high, good performance, sludge dryer offer relatively high, on the contrary, those manpower, financial and material inputs are not in place of the sludge dryer manufacturers, the sludge dryer itself is not very good, so the sludge dryer offer will not be too high. The sludge dryer offer will not be too high.

Finally, sludge dryer market supply and demand and competition. There will be competition if there is a market, and the current situation of China's sludge dryer market is that the supply exceeds the demand, and the market competition is relatively fierce. Sludge dryer manufacturers in order to improve brand share, increase sales, dryer price pressure phenomenon is very serious, so that the market supply and demand affects the price of sludge dryer.
