Cement processing reaction plant by sand washer
Cement processing reaction plant by sand washer
The construction of water conservancy, housing, roads, railways and other facilities have been increasing demand for high-quality aggregate. Thanks to strong market demand for sand and gravel production line has become a hot investment. Sand and gravel production line vibrating feeder. The sand washing machine is an artificial sand (natural sand) washing equipment.
Cement
production points: the first important reaction to occur is the calcining of
limestone (calcium carbonate) into lime (calcium oxide) and carbon dioxide,
which occurs in the lower-temperature portions of the kiln–up to about 1650°F
(900°C). The second reaction is the bonding of calcium oxide and silicates to
form dicalcium and tricalcium silicates. Small amounts of tricalcium aluminate
and tetracalcium aluminoferrite are also formed. The relative proportions of
these four principal compounds determine the key properties of the resultant
portland cement and the type classification (Type I, Type II, etc.). These
reactions occur at very high temperatures with the ingredients in molten form.
As the new compounds cool, they solidify into solid pellet form called clinker.
The clinker is then ground to a fine powder, a small amount of gypsum is added,
and the finished cement is bagged or shipped bulk to ready mix concrete plants.
Some work points on jaw crusher
operation as following: The degree of tightness of the check V-belt crusher,
wear, such as tight loose or badly worn, and should promptly adjust or replace
the belt. Feeding should be uniform, not allowed to join other material. Keep in
mind the material circumstance, if any blockage, should be promptly dredge.
Before the shutdown, must be small jaw broken palate material blocks all broken
before downtime.
The sand washing machine is widely used in the washing of
the material in gravel pits, mining, building materials, transportation,
chemical industry, water conservancy and hydropower, concrete mixing stations
and other industries. It can remove the cover of the impurities on the surface
of sand and gravel, at the same time destroy the vapor layer of the coated sand,
in order to facilitate dehydration, played the role of efficient washing of sand
cleaning. Concrete is produced by mixing cement with fine aggregate (sand),
coarse aggregate (gravel or crushed stone), water, and–often–small amounts of
various chemicals called admixtures that control such properties as setting time
and plasticity.
