250-300T/H Limestone Crushing Plant for Indonesia Again

Good news: Yesterday, one of our Indonesia client who bought from us a 250-300t/h limestone crushing plant in May placed another new order again of same limestone crushing plant.
The working principle of the wheel bucket sand washing machine

When the wheel bucket sand washing machine is working, the motor drives the impeller to rotate slowly after the deceleration of the V-belt, the reducer and the gear. Impurities on the surface of the stone, and at the same time destroy the water vapor layer covering the sand grains to facilitate dehydration. At the same time, add water to form a strong water flow, take away impurities and foreign objects with small specific gravity in time, and discharge them from the overflow port washing tank. The clean sand and gravel are taken away by the blades, and then the sand and gravel are poured into the discharge chute from the rotating bucket to complete the cleaning of the sand and gravel.

Process flow of river pebble sand making

The river pebble sand making production line has a wide variety of equipment, including jaw crusher, cone crusher, sand making machine and supporting feeding, screening and conveying equipment. The configuration of the river pebble sand production line equipment needs to be determined according to the requirements of raw material hardness, output, and finished sand specifications. The river pebble sand production line adopts the configuration principle of more breaking and less grinding, which has high work efficiency and good material discharge. Combined with cleaning treatment, it can quickly produce clean sand.

How to judge the quality of sand and gravel aggregate?

Sand and gravel aggregate is an important raw material in the production of construction concrete and mortar, so the quality of sand and gravel aggregate is related to the quality of construction and other industries. So how do we judge the quality of sand and gravel aggregates?

What kind of crusher has the function of shaping, and the stones produced are in good shape?

Why can the impact crusher make the aggregate produced in a good shape? Then we have to analyze the factors that affect the grain shape of sand and gravel aggregate. In the production of sand and gravel aggregate, the number of collisions and the angle of collision of the stone determine whether the final grain shape is good. So as long as we grasp the collision angle and the number of collisions, the natural rules of the coarse aggregate come out. The impact crusher is just a reasonable combination of these two factors, so it is not surprising that it can produce a good finished aggregate product. There are two-chamber impact crusher and three-chamber impact crusher in impact crusher. Obviously, the three-chamber impact crusher has a better aggregate size because of the number of collisions.
