Size Reduction Equipments and Machinery
Size Reduction Equipments is commonly used in modern construction, and its main function is to make material into smaller , useful material. According the size of the scope, size reduction equipment can be divided into two categories.
One category is crushing Equipments:
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated. Crushing is the process of transferring a force amplified by mechanical advantage through a material made of molecules that bond together more strongly, and resist deformation more, than those in the material being crushed do. Crushing devices hold material between two parallel or tangent solid surfaces, and apply sufficient force to bring the surfaces together to generate enough energy within the material being crushed so that its molecules separate from fracturing, or change alignment in relation to deformation, each other. The earliest crushers were hand-held stones, where the weight of the stone provided a boost to muscle power, used against a stone anvil. Querns and mortars are types of these crushing devices.
The other one is milling Equipments:
A milling machine is a machine tool used to machine solid materials. Milling machines are often classed in two basic forms, horizontal and vertical, which refers to the orientation of the main spindle. Both types range in size from small, bench-mounted devices to room-sized machines. Unlike a drill press, which holds the workpiece stationary as the drill moves axially to penetrate the material, milling machines also move the workpiece radially against the rotating milling cutter, which cuts on its sides as well as its tip. Workpiece and cutter movement are precisely controlled to less than 0.001 in (0.025 mm), usually by means of precision ground slides and leadscrews or analogous technology. Milling machines may be manually operated, mechanically automated, or digitally automated via computer numerical control.

Working principle:
Regardless of the crusher or mill, are driven by the motor, the machine's moving parts, mechanical force, the material crushing, beat, make it the size of the working chamber of the material physical changes, rupture, impact, crushing, cracking and other effects, and ultimately the material size gradually becomes smaller, and eventually reach the desired size.
Liming Heavy Industry is one of the largest size reduction equipments manufacturers in China. It has the strength of the leading technical force, and the main production is the crusher and all kinds of milling machines.
