Steel Ball Has Impact on Grinding Process of Ball Mill
已有 161 次阅读 2012-12-25 15:02The ball mill is a common grinding
machine. The steel ball is a very important component of the ball mill. The size
of the steel ball may have certain impact on the grinding process of the ball
mill. In this article, the experts of Henan Hongxing Mining Machinery will
carefully the impact of the size of the steel ball on the grinding process of
the ball mill.
When the turn rate and filling rate of the ball mill is
constant and the state of motion of the ball charge is constant, the size of the
steel ball may severely affect the particle size characteristics and the
consumption index of the grinding products.
First, the size of the steel
ball may affect the production rate of the ball mill. If the diameter of the
ball is too large, the hitting number may reduce and the grinding area reduces.
In this way, the production rate reduces. If the diameter of the ball is too
small, the insufficient impact force may make the production rate reduce. The
precision of the diameter of the ball can improve the production rate of the
ball mill.
Second, the size of the steel ball of the ball mill may have
certain impact on the evenness of the distribution of the particles of the
products. Too large diameter of the steel ball may lead to too many coarse
particles of the materials. Several experiments have proved that the accurate
size of the steel ball can reduce the largest particle size and average particle
size of the grinding products. In this way, the particle size of the products
may be more even.
Third, the size of the steel ball of the ball mill may
affect the degree of dissociation of the mineral monomer.
Forth, the size
of the steel ball may affect the consumption of the grinding machine. According
to the attrition theory, the attrition degree of the ball is proportional to the
weight of the grinding machine. If the size is accurate, the energy consumption
of the steel ball may be reduced by 10% to 20%.
