The process of hardening or setting is actually a chemical reaction called
hydration. When water is added to the cement, it forms a slurry or gel that
coats the surfaces of the aggregate and fills the voids to form the solid
concrete. The properties of concrete are determined by the type of cement used,
the additives, and the overall proportions of cement, aggregate, and
water.
Operation of the process of sand production line work, the motor through V-belt, reducer, gear reducer driven
impeller rotating slowly, sand and gravel to the trough into the wash tank, then
roll in the impeller, driven, and each other grinding, remove the cover on the
gravel surface impurities, while destruction of the vapor layer coated sand, in
order to facilitate dehydration; then add water to form a strong current, timely
impurities and a small proportion of foreign body away, and from the wash tank
overflow export discharged to complete the cleaning effect.
In the crushing
of the grinding operation, has an
irreplaceable role, but how can we effectively promote the development of the
mill?
Ensure proper cylinder speed, raw materials and grinding media formed
into the falling movement. Speed is too slow, the centrifugal force is small,
the friction is small, the grinding media can not be increased with the cylinder
wall, it is impossible to form into the falling movement, on the contrary, the
speed is too fast, the centrifugal force on the friction and grinding body close
to the cylinder wall rotation, can not be formed into the falling movement, into
the falling movement, grinding body the raw materials, the formation of the
collision, and only abrasive, reduced efficiency, cylinder speed is too slow or
too fast are not desirable.
Clean sand from the leaves away, the final sand
and gravel from the rotation of the impeller into the trough, to complete the
cleaning effect of the entire sand and gravel. Clean aggregate to improve the
quality of the concrete, engineering and construction companies favor the
object. Clean gravel material on the market price is relatively high. Sand
production line sand washing machine is not a core equipment, Zhengzhou Hongxing
proposed sand and gravel production lines, investors take into account in the
purchase of equipment, sand washing machine, sand washing machine, a relatively
low price, the quality of the aggregate there are a big improvement.
