CHALLENGE
Cement is the most expensive component of the concrete compound
The workability of the final concrete mix and the amount of cement used are two of the most important parameters in concrete production. These parameters, in turn, are mainly affected by the quality of sand used in the process.
The consistency of the sand can be a challenge when using natural or crushed sand that has not been produced in a well-controlled industrial process. Inconsistent sand quality leads to a higher safety margin, which results in an unnecessary increase in the amount of cement used. Cement is the most expensive component of the concrete compound, representing more than 50% of the cost of raw concrete, but less than 20% of the volume.
Characteristics of fine-sized aggregates in concrete are also crucial. Only a perfectly cubical and rounded shape of all fractions and their consistent quality can form an easily workable concrete mass. This allows the lowest possible amount of cement to be used in the final cement mix.
SOLUTION
Crushing process
Nowadays artificial sand is widely used in highway construction, concrete making, and relevant construction fields. Due to the gradual shortage of natural sand resources and the booming construction industry, machine-made artificial sand becomes even more popular in the market. Various types of rocks can be processed into sand including granite, natural river pebbles, basalt, and limestone etc.
The raw material is fed regularly by the vibrating feeder to the primary jaw and secondary jaw/cone/impact crusher for crushing. The crushed material is then transported by a belt conveyor to the vibrating screen for sieving. After sieving, proper sizes (<30mm or <40mm) would be transported to the sand making machine directly, while the oversized material will be returned to the secondary crusher for reprocessing. The crushed material from the sand making machine will be transported to another or the same vibrating screen for sieving again. The sand which meet fineness requirement can be transported to a sand washing machine for cleaning, and then be retained as final products. Oversized material will be returned to the sand making machine and screen for repeated crushing & sieving until all the materials are turned into sand. We can provide professional solutions to meet different capacity requirements.
