Dozen arenaceous machine, make arenaceous aircraft equipment produce a mechanism arenaceous in Shi Fenhan estimates a demand- - SBM
Our country now still with the river arenaceous regard main fine aggregate as origin, dozen arenaceous machine, make arenaceous aircraft equipment produce the research with arenaceous mechanism and application to still be in start level, GB is arenaceous to hitting machine, make arenaceous aircraft equipment produce a mechanism arenaceous in Shi Fenhan estimates a demand stricter. With natural arenaceous photograph is compared, make the arenaceous machine, mechanism that controls production of arenaceous aircraft equipment arenaceous grading is poorer, fineness modulus slants big, have the face acuteness of coarse, grain has the characteristic such as edges and corners, this is advantageous to the felt of aggregate and cement, but also increased concrete to mix at the same time the obstruction of flow closing matter, the liquidity that creates concrete very easily is undesirable. The dosage of material of gel of excel in concrete is bigger, return mix into among them person silicon pink in order to assure intensity, the mix into of silicon pink is entered still can add powdery form content, make water requirement increases, cause the accretion of viscosity inevitably so, how to make the mechanism arenaceous concrete that make up satisfies pump to send the demand of concrete, make its have good character of service, it is the problem that remains to solve. Want to make arenaceous machine, make arenaceous aircraft equipment produce quality admirable mechanism is arenaceous be about to choose make arenaceous aircraft equipment suitably, the requirement of the respect such as the granuality size with the arenaceous mechanism that differs as a result of utility is different, what choose so it is OK to make arenaceous aircraft equipment the size that gives makings size according to the adjustment with effective agile demand, can be adjusted so when produce according to demand, the can better concrete raw material that produces different utility. Give the size of makings besides OK and convenient adjustment beyond, equipment has productivity to wait for an advantage by force even, because the demand of concrete is very big, dozen of arenaceous machine with only powerful productivity, make ability of equipment of arenaceous aircraft equipment satisfy manufacturing requirement, plus people is more powerful also to the consciousness of environmental protection now, so equipment cannot is opposite in producing a course the environment comes into being pollution, and equipment is handling the side such as difficulty also is to have a demand, present equipment wants in a word facilitate safeguard, operate and environmental protection productivity is strong, ability suits to make arenaceous demand. Our country in recent years freeway the development that wait, make the demand of concrete very big, and this demand still is in as the development of these industries grow ceaselessly, but the natural arenaceous resource of high grade fine aggregate is less and less, have some of area restriction as a result of natural condition, do not have natural arenaceous resource basically, this makes a mechanism arenaceous use in concrete the quantity is increasing. And progress as concrete technology, people hope concrete has more superior performance, if high strenth, senior engineer makes gender and tall wear,also be in ceaseless implementation is worn. The quality of the concrete that current our country produces basically had realized these demand, the quality of concrete depends on the quality of producer goods, must ask the dozen of arenaceous machine, mechanism that controls production of arenaceous aircraft equipment is arenaceous so have good quality.
