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

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

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.
