Sand gravel aggregate production line

Shanghai production of sand and gravel production line equipment can achieve energy saving and environmental protection requirements, the model is complete, if there are special needs, I can plant design size according to your requirements Raymond Mill. Sand and gravel aggregate production line aggregate particle size distribution test is a worthwhile experiment study. The main experiment requires rack pan balance scales, sieve, sieve shaker, oven, ceramic plates, brush, etc; experiment is divided into three steps. 1. sand samples for particle size distribution test, the particle size should not exceed 10mm. Before sampling, should first like sand through 10mm sieve, sieve residue and calculate their percentage. Then take full mix in the wet state, with each quartering reduced to less than 550g of sand samples in duplicate, at (105 ± 5) ℃ drying to constant, after cooling to room temperature, respectively, according to the following procedure test. 2. Weigh the sand sample 500g, placed according to the order of mesh size sieve set uppermost One screen (ie 5mm sieve), and stamped the entire screen is mounted on the shaker surface forces, shake 10min, the Under cover sieve, sieve size according to the order on a clean enamel tray one by one by hand sieve Raymond Mill, until every minute of not more than 0.1% by volume of the total sand sample. Sand production line where affordable particles pass through the sieve is incorporated under the One and One and lower sieve sand like sifting together. Order, until all the various sieve sieve last. 3. When the sand on each sieve sieve margin of more than 200g, the screen should be more than the sand sample was divided into two, and then sieved, and twice as the sum of the sieve sieve sieve over the amount. Purchase at the end of sand production line, mineral processing production line equipment customers can go to the factory inspection, thank you for your support of our plant equipment, the equipment can give you price, to act now.
