Compost Screening Equipment

Screening is the process of separating particles according to their size. most machines sieve material through a moving mesh, allowing smaller material to pass through then fall onto a conveyor or a specific area from which it can be moved to a suitable storage location. some use air-separation.

Screening compost is the most common method of adding value, the key aims of which are to create compost grades with particle size ranges suited to the product type (eg, soil conditioner, mulch, top dressing, ingredient for manufactured topsoils and growing media) and remove any physical contaminants that may be present in the unscreened composted material. The particle size range for a specific compost grade will depend upon your product type, the markets in which it is intended to be used and any specific requirements of individual customers.

Trommel screens, deck screens and star or finger screens are the most commonly used types of screening machines. A variety of sizes and types are available, some with very sophisticated feeder mechanisms, variable speed motors and interchangeable components and accessories. When making your choice, take into account your processing efficiency requirements.

Trommel screens

Trommels are the most popular type of screen and consist of large rotating mesh drums, positioned at an angle. The material is deposited into the drum and as it rotates, the material passes through holes in the mesh onto a conveyor. The oversized material remains in the drum and is discharged onto another conveyor when it reaches the end of the drum.

The diameter of the holes in the mesh determines the size of the screened fraction and the length
of the drum and its rotation speed determine the throughput. A variety of mesh hole sizes are available and some manufacturers make screens with two or more different mesh sections, which creates more than one particle size range of compost.

Star screens

star screens use rubber star shaped components or discs, mounted on a series of rotating shafts. As the material passes over these, the smaller particles drop between the shafts onto a conveyor while the larger particles are carried forward. The speed at which the shafts rotate dictates the particle size range of the compost.

Deck screens

Deck screens are fitted with the desired mesh size and operate on a horizontal plane or at an incline. The machine vibrates the compost across the mesh and particles smaller than the size of the mesh holes fall through, leaving the oversized matter on the mesh
or discharged at the bottom if the mesh is set on an incline. Finger screens are similar but utilise rubber fingers rather than a mesh.
