A question often asked by users of different stone crushing plant: Why is the price difference between devices of the same model so large? Why are some production lines with the same capacity in the millions and some in the tens of millions? Why is the quality of finished products of similar production lines has big difference?
For the various equipment required for ore crushing and sand making, when selecting, not only the type and performance of the equipment should be paid attention to, but also the service life of the wear-resistant parts of the equipment, which will affect the efficiency and maintenance cost of the equipment in the later use process great influence.
For the stone crushing process, if the selected equipment is not suitable, then the production will cause a large loss to the equipment. Therefore, according to the different properties of different stones, different production equipment needs to be selected. So for the crushing process of hard rock, which equipment should we choose? Let's take a look.
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.2022.09.19
There are three main types of combined crushing and screening equipment: stationary, semi-mobile and mobile. The mobile crushing station is divided into tire type and self-propelled type according to the way of movement. These three types can be used completely independently or mixed. For example, the primary crushing unit is mobile, which is convenient for multiple ore sources to be crushed nearby, and then transported to a fixed location by a belt conveyor, while the secondary, tertiary and screening units are fixed. Which type of sand and gravel yard adopts should be determined according to the frequency of equipment movement during the operation of the sand and gravel yard. The equipment does not need to be relocated. The fixed type is used. It may be relocated once in a few years. The semi-mobile type may be used, and the tire mobile type may be used for several relocations within a year. If the movement is particularly frequent, the self-propelled type can be used.2022.09.09
There are many kinds of raw materials for sand making, and the quality of finished sand processed by different raw materials is different because of their different properties. So, as one of the natural mineral resources, can weathered stone be used to make sand? In fact, weathered stone is tortoise, which is one of the rich mineral resources in nature and a good raw material for sand and gravel. The use of weathered stones as raw materials to produce machine-made sand not only has good sand grain shape, but also has a wide range of uses.2022.09.09
From raw materials to finished products, sand and gravel production generally needs to go through seven processes: feeding, coarse crushing, fine crushing, sand making, screening, cleaning, and transportation. The main equipment used and its performance are as follows:2022.09.06
The working principle of the cone crusher is very simple, mainly relying on the force of extrusion to crush materials. The motor will drive the upper eccentric sleeve to rotate through the middle transmission device, so that the moving cone rotates and swings in the crushing chamber. The stones are are squeezed, rubbed between mantle & concave, and broken into smaller particles.2022.09.06
According to the degree of maintenance, the maintenance of jaw crusher can be divided into three types. Among them, medium and minor repairs with little degree of maintenance are the main methods of daily production maintenance, and major repairs are regularly formulated and implemented to ensure that the equipment can continue to meet production requirements.2022.08.29
