A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, 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.
1.4.7 Pulverized Silica or Silica flour. Silica flour is called as pulverized silica. Pulverized silica can be easily added up to 3% which increases the hot strength and finish on the surfaces of the molds and cores. It also reduces metal penetration in the walls of the molds and cores. 2. Different types of Molding Sand:

Coal Specks It is a type of dirt. These are black, insoluble particles that are often in a pulverized condition, as a result of the action of calender rolls. Coating Defects Coating streaks are continuous defects that may be very clear and long, but they can be short and extremely narrow. Other coating defects are skips and splashes.
Brickmaking Processes. PREFACE: There are three processes used in making bricks, varying primarily in the amount of water mixed with the clay. 3 STIFF-MUD/EXTRUDED: In this process, used for most building bricks, only enough water is added to the clay to make it into a stiff paste that can be extruded through a die into a long ribbon or column of clay.
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

First, iron oxide fines, pulverized coal and a binder are formed into pellets. Second, the pellets, two to three layers deep, are heated in a gas-fired rotary hearth furnace for 15–20 minutes to produce sponge iron. Subsequently, the iron must be desulfurized. The coal in the pellets provides much of the energy required in the second phase.
