The crushing for Concrete in road construction could be mainly divided into two steps
Sep 3, 2014-China-As the introduction from the technician from Famous China www.machine-crusher.com
supplier Zhengzhou Unique Group Co., Ltd, Concrete plays a vital role
in road construction and civil engineering. Concrete is generally used
as a cementitious material of cement, sand, stone for aggregate; and
water meets by a certain percentage, after mixing, molding, maintenance
derived from, and sometimes according to the needs of the construction
process, you can add additives and admixtures to improve concrete
performance, sand and gravel aggregate crushing and screening technology
also play an important role.

Pre-screening
machine can be mixed in the sand mine in the physical separation of the
wet clay in order to achieve these types of materials hard rock crusher
with a single paragraph break. The screening machine can withstand
large impact loads of ore, in line with the needs of pre-screening, it
has self-cleaning function, can eliminate the sticky and wet adhesion of
materials, smooth operation. Fluctuations in pre-screening machine will
roll the powder pre-screening of low-grade, may become available to
improve the quality of ore. Screening material will be sticky and wet,
you can remove the plug crusher, the ore particle size in the
pre-screening qualified to carry out the separation of the crusher can
reduce wear and improve the broken system or reduce the productive
capacity of the crusher specifications. Jaw stone crusher and configure
pre-screening machine before passing material isolated material, and can
reduce the use of too crushed. With the wave roller pre-screening
technology continues to mature, now almost more than one mainframe
limestone used in the pre-screening single-stage crushing system.
For the larger abrasive limestone, it usually uses two stage crushing. This machine commonly use wagon drill
or a cycle. Broken up in the model and the type mill, ball mill
grinding the case of raw materials, can be used in hammer crushers, the
material of its smaller, higher fines content; if follow-up is the
vertical roller mill grinding, the Cone can use pieces of broken
machines. If the coarse particle size of ore passes broken out after the
screening, you can reduce the size of broken machines, so that
selection has energy saving effect.
For the limestone
deposits of the Quaternary cover, the ingredients if the ingredients
meet the requirements, you cannot be stripped and used as raw clay. A
combination of both would be more economical crushing method. If the
second plant material used is high plasticity clay and more water, which
separate processing, transport and stockpiling are extremely difficult,
even under such circumstances should be taken mixed with limestone
crushing method.
