Compost Turner The compost turner for manure composting utilizes a chain conveyor to effectively mix, decompose and turn over the composting ingredients. This standard composting device is highly efficient and low in operation cost. The machine is able to process large amounts of livestock manure for exceptional results and finely grained organic compost.

Belt Press
Belt press type polluted sludge dryer is a kind of solid-liquid separating technology that integrates modern science. Due to the advantages of high efficiency in polluted sludge treatment, low maintenance fee, safe and reliable automatic operation brought by the belt filter type sludge dryer, it has drawn a lot of attention from worldwide technicians and engineers to complete its research and development. The principle  The principle to design a Belt press type polluted sludge dryer is mainly to conglomerate the sludge by polymer coagulant and apply the combination of squeezing and shearing effects to destroy the interface between polluted sludge and water molecules, so as to achieve the goal of dewatering. Its dewatering speed and moisture rate depend on the application design of roller pressure and the know-how of the shearing angle of sludge entry. Operating procedures  the process of dewatering includes mixing of the entering sludge, gravitational dewatering, wedge preloading, low-pressure roller, medium-pressure roller, and high-pressure roller for squeezing out of water. Mixing of the entering sludge: a unique design of tank mixing the polluted sludge and chemical agents at a constant speed for sufficient conglomerating reactions. Gravitational dewatering: a particular design of guiding plates and separators with appropriate mesh can remove a major portion of the water at the surface without destroy the conglomerate structure of the sludge. Wedge preloading: a method which applies the simple harmonic preload to incrementally increasing the pressure for stabilizing the entry of sludge and avoiding the lateral leakage of sludge. Low-pressure roller: uniform distribution of the holes on the surface is helpful for draining of a large amount of free water. By the effects of the relative velocity and the shear stress between filter clothes and roller, the slight rubbing will recombine the sludge. Medium-pressure roller: the key point is how to
