The invention relates to the method for milling and separation into fractions of solids and granular materials in a controlled airflow. The device for milling and separation of solids and granular materials consists of a round milling chamber with a system of pneumatic separation comprising of a vertical cylindrical body that has an uploading slot for solids and granular materials and unloading channels for the milled products of light, medium and coarse fractions. A rotating disc and a conical divider are located inside a vertical cylindrical body. The rotating disc has plates (hammers) and removable blades of different sizes and configurations. System of pneumatic separation consists of a milling chamber, an air slugcatcher, channels for the milled material, and a chamber of higher pressure. Such construction of the device allows to obtain products of a highest quality, and to improve the separation by dividing the material into three fractions: light, medium and coarse.

An abrasion resistant distributor plate assembly mountable within a rotor of a vertical shaft impact crusher to protect the rotor from abrasive wear caused due to material falling on to the rotor. The distributor plate assembly includes a main body, wear-resistant inserts mounted on the main body having a wear resistance greater than the main body, and an elevated central component directly mounted on the main body, which has a wear resistance greater than that of the inserts.

Provided is a non-belt automatic mechanized sampling system for truck, including: a working platform including a transport channel and a slide rail extending along a first direction, the transport channel is arranged under the slide rail and makes the truck pass; a first frame configured to slide with the slide rail; a sampling mechanism (configured to collect materials from the truck along a second direction perpendicular to the first direction, the first and second directions are arranged horizontally; an integrated sample preparation component including a discharging mechanism and a feeder, a crusher, a constant mass dividing machine and a sample retention barrel. The feeder transports the material to the crusher. The crusher crushes the material and transports the crushed material to the constant mass dividing machine. The constant mass dividing machine divides the crushed material into samples to the sample retention barrel, and the discarded material to the discharging mechanism.

A pulverizer may have such features as an ability to detect wrapping as well as possibly deter wrapping. A processor may also adjust the speed of rotation of the arms within the pulverizer and/or the speed of feed of input for various considerations. In fact the rotation direction may be reversed for at least brief periods of time in an effort to remove wrapped material. Vibration may also be sensed and efforts to prevent damage may be instigated by a processor.
