Four factors influencing the discharge of Crusher

  Whether it is jaw crusher, hammer crusher, conical crusher, compound crusher and other crusher equipments are often used in ore dressing, sand production line, construction and other industries. The production quality of the crusher has a direct impact on the economic benefits of the enterprise, so what are the factors that affect the quality of the pellet of the crusher?

  1 breaking ratio

  The crushing ratio is the ratio of the particle size of the imported material and the finished product after crushing. The bigger the ratio is, the bigger the crushing ratio is, and vice versa. The breakage ratio of large needle increases, and this rule is applicable not only to jaw crusher, but also to conical crusher. It has nothing to do with the type of crusher, but if the crushing ratio is too small, the output of the whole system will decrease. Internal circulation increases, crusher wear increases, economy is poor, production efficiency is low. Therefore, in the whole production process, it is very important to choose the appropriate crushing ratio.

  2 feed granularity

  When the feed granularity was reduced from 100mm to 50mm, the needle flake content in the finished product decreased 38%.

  3 cycle load

  In a closed circuit cycle production process, the grain shape of stone will become better by adjusting the discharge port and increasing the load in the cycle. During the whole process, the wear and tear of the equipment in the system will increase due to the increase of the circulating load, but when the discharge port is adjusted, The load of the main crushing motor can be reduced, and the grain deformation of the finished product is good.

  4 Open and closed circuit

  In the second-stage crushing process flow, the circulating and closed-circuit circulation of the circulating separation path is carried out, the former is called the first screen and is broken, the latter is called the first crushing and the rear screen, such that the yield of the finished product is increased and the needle-like content is also increased. The first crushing back screen refers to the whole system is a closed system, no broken material is lost, and the circulating load is large, but the product is good in particle shape.

  The production line and equipment should be reasonably selected, and the grain size of the product should be controlled properly so that the grain shape of the product will be better.

Active lime is produced from limestone dolomite chalk and other minerals with high calcium carbonate content by the calcination process under the temperature of 1000-1100 ° C. There are various processes for the active lime production mainly
