A blower casing having an inlet in a side wall thereof and having an outlet in an upper portion of a peripheral wall thereof, and an impeller to rotate within the blower casing take in a composite including solid resin through the inlet and throw the solid resin radially outward and toward the outlet, are included. Multiple crushing blades each of which is in the form of a saw blade are arranged at intervals on an inner peripheral surface of the peripheral wall of the blower casing, the multiple crushing blades being configured such that the solid resin is crushed by collision with the multiple crushing blades.

A vacuum cylinder shredder for lawn debris using at least one string trimmer assembly and a collection mat.

An autogenous impact mill (10) is operative to size reduce friable material particles processed through operation of the mill. At least one impeller (58) rotatable within an interior area (44) of a housing (12) of the mill is operative to produce one or more air jets. The air jets are operative to suspend material particles using the Coanda Effect. Other particles moved by the air jets bounce off ricochet bars (74) and impact suspended particles so as to break and reduce the particles to a suitable size to pass through a screen (110) to an outlet opening (42).

Reflective luminescent markings on a road or sign surface are formed by applying onto the surface a base material which is liquid in an initial state for application and sets or cures to form a solid layer after application where the base material contains a fine/medium filler material of glass ground from recycled materials in a rotary mill. Coarse material from the grinder is separated out and supplied as a separate material to be applied onto the surface of the layer of base material and fine ground glass. The base material is connected or impregnated with a luminescent material such as photo luminescent 2 4 6 trichlorophenyl in a binder such as polyurea.

A circulating mill, comprising primary mills (47, 57) and secondary mills (49, 61), and first and second inner circulation pipes (48, 58, 52, 64). The first inner circulation pipes (48, 58) are connected to air outlets of the primary mills (47, 57) and inner circulation pipe interfaces (3, 11), and the second inner circulation pipes (52, 64) are connected to air outlets of the secondary mills (49, 61) and the inner circulation pipe interfaces (3, 11); the inner circulation pipe interfaces (3, 11) are located on a housing (1) of the primary mills (47, 57) or the secondary mills (49, 61), or located on feed pipes (56, 60) of which one end is connected to the air inlet of the housing (1); a kinetic energy recovery device is mounted in the feed pipes (56, 60), and the kinetic energy recovery device is connected to an impeller in the housing (1).
