Jaw crushers. Jaw crushers were invented in 19 th century and are mainly used as primary crushers to produce material that can be transported by belt conveyors to the next crushing stages. The crushing process takes place between a fixed and a moving jaw. Shaft rotation, along with the toggle plate, causes a compressive action of the moving jaw.
4. Grinding process. In the ball mill, the material is mainly crushed by impact and friction. In the vertical grinding mill, the material is mainly extrusion, and grinding is the auxiliary. The residence time of the material in the vertical mill is 23 minutes, while in the ball mill it takes 1520 minutes.
one as a floating roll. The required comminution pressure is transmitted by a hydraulic system via the floating roll. The following features distinguish the POLYCOM® highpressure grinding roll from other grinding systems: m A hydropneumatic spring system builds up a pressure of up to 250 MPa in the layer of material between the rolls.
The roll crusher is mainly composed of fixed roller, movable roller, machine frame, shield, protecting guard. The machine is driven by the Vbelt of the motor, which makes the two rollers rotate through the speed reducer chain, with the result of crushed materials. The roller is the main part used for crushing materials.

Raymond Roller Mills: More than 2,000 roller mills have been supplied since the first mills were designed in the late 1800's. These early machines were the forerunner of the heavyduty, rugged ringroll mill manufactured today. The roller mill provides the needed flexibility to economically and efficiently process a wide variety of materials.
Roll crushers are arbitrarily divided into light and heavy duty crushers. The diameters of the light duty crushers vary between 228 and 760 mm with face lengths between 250 and 460 mm. The spring pressure for light duty rolls varies between and kg/m.

Crushing is usually more energy efficient, but this becomes less clear for very fine crushing in tertiary or later stages. Commonly used machines for large scale crushing include gyratory and twin roll crushers (for primary crushing) and high pressure grinding rolls (HPGR) and cone crushers (for secondary crushing).
