Various embodiments of horizontal shaft impact (“HSI”) crusher systems, methods and apparatus are disclosed herein. Some HSI crusher embodiments are provided an adjustable feed angle. Some HSI crusher embodiments are provided with an adjustable curtain position.

A control method of a crusher for elements to be recycled or disposed of, which includes a crushing assembly, to which the elements to be recycled or disposed of are provided, and pushers acting toward the crushing assembly to push the elements to be recycled or disposed of, includes a measuring step of the current absorbed by the crusher, a comparing step of the current value measured against a first predetermined value, and a reducing step of the push intensity of one or more of the pushers toward the crushing assembly in case the measured current exceeds the first predetermined value, the pushers being controlled separately from each other in order to partialize the push force and the push areas.

A comminuting apparatus for comminuting comminution stock like recyclable material, waste and product residues, including a comminuting rotor mounted rotatably to a machine frame and having comminuting tools arranged thereon, a receiving region for receiving comminution stock and a feed device having a ram device which is moveable in the direction towards the comminuting rotor by a drive device and which is adapted for feeding comminution stock to the comminuting rotor. The comminuting apparatus is distinguished in that the drive device of the feed device has at least two spaced electric actuators which are controlled by a control device and which are connected at the drive output side by a transverse member, wherein the transverse member is operatively connected to the ram device by a resilient damping device.

Crushing mill including a crushing chamber, an inlet pipe of the refuse to be crushed connected to the crushing chamber, and a thruster member associated to the inlet pipe; the crushing mill includes a compactor apparatus for the refuse to be crushed provided with one or more presser elements positioned in correspondence to the inlet pipe of the refuse to be crushed and configured to be moved from at least a first inactive position, in which they allow the loading of the refuse to be crushed into the inlet pipe, to at least a second active position in which they compact the refuse in the pipe; the mass of compacted refuse in the inlet pipe is sent to the crushing chamber by means of the thruster member.

Shredding device for shredding material comprising a housing: a rotor and one or more counter blades which are arranged in the housing such that they interact for shredding the material; a pusher element that is movable such that it pushes the material to be shredded in the direction towards the rotor and the counter blades; a hopper for feeding the material which is arranged movable on the housing between a first and a second position, where, in its first position, the material may be fed to the rotor and the counter blades, and in its second position, the rotor and the counter blades are freely accessible from the exterior of the shredding device.
