Mechanism sand machine production line effectively improve the cement concrete aggregate
Inspection of cement concrete strength evaluation methods for unity, improve enterprise management level, ensure the quality of the cement concrete strength, countries are now approved the cement concrete strength inspection evaluation standard (GBJ107-87) as the national standard. Ordinary concrete cement market at present is mainly composed of cement, coarse aggregate, fine aggregate (gravel and pebble) (sand), additive and water mix, the hardening of an artificial stone. Main production equipment by professional mechanism sand production line equipment, efficient vsi sand making machine and a full set of production line equipment composition.
Concrete aggregate processing need use stone crusher and sand making equipment( such as pulverizer, grinder, mill and so on) to complete processing of coarse and fine aggregate, fine aggregate such as sand grain size distribution is reasonable, low silt content was beneficial to the improvement of the strength and workability of sand. Cobble sand making machine adopts the hammer head is more durable, eliminating the screening program, use the straight-through sanding, sanding degree of stability, degree of thickness is more accurate, more stable production. At present there are three kinds of artificial sand making production technology: two stage crushing, secondary screening and application of a system to coarse broken, broken in to check the screening, system sand to grading sieve, artificial sand and gravel. Which play sand machine/system sand machine is the focus of the choice and use, in addition to the production high quality.
In addition, the preparation of high-strength cement concrete application of coarse sand, average flow medium sand concrete. Sand fineness modulus affects the sand ratio and water use of concrete, so should pay attention to the choice with sand, especially the application of artificial sand to strict...
