The first step in the production of manufactured sand is crushing the rock to a gradation that when classified, by only removing the excess material passing the #100 and #200 sieve, will meet the C-33 Sand Specification on all the other sieves (#4, #8, #16, #30 and #50). Normal manufactured sand will result in sand with less then 80% passing ...
Let us now learn how the choice of River sand or Crushed sand affects the overall strength and lifecycle of the project. Crushed sand is made by mechanically crushing basalt, granites, or other stones.
For example, due to the low hardness of dolomite, large pieces of dolomite crush process either in the form of a jaw crusher + impact crusher+sand making machine or in a single hammer crusher. The former has multiple equipment configurations and high costs, but the finished product has higher quality.
Properties of M Sand. The shape of Crushed sand is cubicle and Angular and has a r ough texture and hence it is better for concrete.

The quality of sand used in concrete construction significantly influences the strength and durability of the final product. Therefore, conducting a variety of tests, including sand quality testing, is vital to confirm the sand's suitability for concrete. These tests include: Silt content examination. Grading analysis.
Mastering the correct handling methods for common faults in hammer crushing will timely and accurately solve problems, ensure the effective working time of the hammer crusher machine, and provide strong guarantees for production output. Next, let's look at the common faults and solutions of the hammer crushers.
4. Crushing index control. The crushing index value of machine-made sand with better particle shape ranges from 20% to 25%. The content of needle flakes in machine-made sand is most sensitive to the crushing index value. The crushing index value of machine-made sand is generally above 30%, or even higher.
Gradation of sand need to be checked. Poor quality of crushed sand will affect workability, cement demand, strength and hydration of cement.
