River pebble is a pure natural stone, Natural river pebble ore is produced into river pebble sand after a series of processing such as crushing, sand making and screening, River pebble sand is an important industrial mineral raw material. River pebble sand is also widely used as concrete aggregate and has high application value. To further process River pebble, impact crusher and new sand making machine can be used, These two machine have high efficiency.
As a crushing equipment favored by users, SMMVIK Machinery impact crusher has received good feedback from customers: the mobile crushing performance is stable, the output is up to standard, and the shaping effect on river pebbles is very good! The detailed parameters of the crushing station can be used as a reference for other river pebble stone plants, because the grain size requirements of finished products of each stone project are different. According to different processes and stone grain size, crusher products with consistent performance can be selected. The main processed materials are river pebbles, mountain rocks such as limestone, granite, basalt, diabase, andesite, etc, and artificial sand making of ore tailings.
River pebble new sand machine is widely used for fine crushing of limestone, calcite, granite, basalt, river pebble, cement clinker, quartz stone, iron ore, bauxite and other minerals.
When these two kinds of crushing equipment are used for deep processing of river pebbles, the working principle is almost the same. Let's take a look at how the processing technology of the sand machine is developed? The material enters the river pebble sand making machine from the feed hopper and is delivered to the material distributor. The material is divided into two parts. One part enters the high-speed rotating impeller, and then is ejected from the three evenly distributed flow channels of the impeller at a speed of about 65 m / s. then, it impacts the material lining in the vortex branch chamber together and is bounced by the material lining.
It impacts the top of the vortex chamber obliquely upward, and changes its movement direction and deflects downward, The material emitted from the impeller channel forms a continuous material curtain. Such a piece of material is subjected to two or more times of mutual impact, friction and crushing in the vortex crushing chamber, and the crushed material is discharged from the lower discharge port. Part of the river pebbles of the system sand machine are made into sand, which is washed by the sand washing machine (optional) and then made into finished sand. The other part of the sand that does not meet the requirements is returned to the sand making machine for crushing again.
