Mixing: It is a very important job before shrinking. Only the sample that has been thoroughly mixed can begin to shrink. There are four commonly used methods. (1) Iron shovel mix method: i.e., a sample spade tapered piled heap. Then, a small wooden column is placed nearby to center the sample, and the sample is gently sprinkled on the axis of the wooden column to form a new cone. A large number of samples can be mixed by this repeated stacking method. (2) Ring cone method: The conical pile is turned into a large ring by using a shovel, and then the samples on both sides of the ring are piled into a cone, and the mixing of a large number of samples can be achieved by repeating several times. (3) Rolling method: Fine particles and a small amount of samples can be mixed by this method. Place the sample to be mixed on a blanket or tarpaulin, lift the diagonal of the tarpaulin, and roll the sample back and forth. Change the diagonal of the tarp once for each roll. After 5-6 tumbling, the sample can be thoroughly mixed. (4) Groove sampler method: a small amount of fine-grained or silt ore sample, which is divided into 2 equal parts by a trough type sampler, and can also achieve the purpose of mixing. Shrinkage: Commonly used for stacking cones or grid method. The former flattens the regular cone into a disk. Then, the cross plate is divided into 4 parts; the diagonal two points are used as the sample for shrinking. The grid method is to spread the sample thinly on a tarpaulin or a blanket and divide it into small squares. Sampling by grid with a flat bottom shovel. Sometimes you can use the slot divider to make a two-pointer.
The wear parts of general Slurry Pump are
often made of high quality hard metal or non-metallic
materials. The metal materials often used are high-chromium wear-resistant cast iron. The spare parts for pumps made
of these materials possess
the advantages of excellent resistance to abrasion,
corrosion and erosion, maximizing wear life and extending maintenance cycles.We provide OEM service to customs and we can
manufacture spare parts according to the construction drawings and samples.
