A portable roller compactor for compacting waste located in a container, which is open on the top, has a frame-like basic structure and an articulated arm, one end of which is supported by the basic structure, and the other, free end of which supports a roller compactor that essentially can be rotated about a horizontal axis of rotation. The articulated arm of the roller compactor is pivotably attached to a sliding carriage, which is mounted on the frame-like base structure and can be moved in a longitudinal direction.

A device includes a compartment for separating the solids and liquids. The compartment includes a base that is concavely curved according to a cylindrical portion having a transverse axis and is formed of a sieve, an idler roller mounted transversely on an arm, a drive which actuates the arm, and resilient means for adjusting the pressure exerted by the rollers. Both the contact interface between the sieve and the roller and the rotational interface between the roller and the arm are made of a non-metal material on at least one of the two contacting surfaces that form each of the interfaces, such that, there is no metal-on-metal contact between surfaces moving relative to one another at the interfaces.

The invention relates to an apparatus (1) for dewatering wood material (2). The apparatus (1) comprises a first roll (3) and a second roll (4) that form a nip (N1) in which water can be pressed out of the wood chips (2). An endless permeable conveyor (5) is arranged to pass through the nip (N1) and carry wood chips (2) through the (N1). The invention also relates to a method of dewatering wood material in which the inventive apparatus is used.

A small-scale waste processing device includes a housing, wherein a conveying cavity is provided in the housing, a screw is rotatably provided in the conveying cavity, a rotating cavity is provided in the housing, and the rotating cavity and the conveying The cavity is connected, and a rotating block is rotatably provided in the rotating cavity. A squeezing mechanism is provided in the rotating block. A first filter is fixedly arranged on the right wall of the rotating cavity. The present invention can pass kitchen wastes through Most of the water is squeezed out, and then the water in the waste is thrown out by throwing water to make the waste more dehydrated. The discharged waste water can be directly discharged to the sewer, which avoids clogging of the sewer and saves maintenance costs. The dehydrated waste passes through Grinding and squeezing makes it difficult to make full use of the packing space during the later packing process of waste materials, and at the same time avoids the leakage of waste water from the waste materials, causing pollution to the environment.
