The problem of processing of silt deposits is solved. Extremely important achievement of SP-Co plant.

A series of experiments on development of technology of processing (utilization) of sludge deposits of fields of a filtration (solid part of sewer drains) has come to the end with success. The first experiments have been made in 2012, however they haven't led to positive result on the reason of extremely high stickiness and viscosity of initial raw material. At hit in the Unit of drying crushing AS-4 the most part of silt stuck on Unit walls, and only the insignificant part was brought out of the Unit in the dried-up form. For the solution of this problem and in coordination with the potential customer from Hungary the decision on carrying out experiment on processing of silt in mix with an organic filler has been made. As such filler damp wood sawdust has been chosen. However, at the same time there was one more complex technical challenge – production of the equipment capable to continuously make homogeneous mix of two materials having absolutely different physical characteristics. And such mixer has been developed and manufactured by us. The silt taken for experiment had initial humidity about 80%, was black color, possessed such stickiness and viscosity, as dough (solid oil). At the exit of the technological line powder of dark gray color with a size of particles 0,5 … 3 mm, humidity suitable for a granulation, briquetting or direct burning (12-14%) has been received. Thus, LLC SP-Co has successfully finished development and test of technology of utilization of silt deposits, has solved a problem which for many cities of the world is one of the most painful today.
