Under the surface of vibrating screen, the particles in the sieve are shaken on the direction close to the vertical mesh jitter, and the higher the vibration frequency, the better the screening effect; on the surface of shaking sieve, the particles slide along the screen surface. Due to the lower the shaking sieve shaking frequency than the frequency of the vibrating screen, the shaking sieve screening effect is poor. Circle cylinder sieve screen surface is easily blocked, so the screening efficiency is low. Therefore, the choice of the type of vibrating screen should be based on the nature of the material in order to maximize efficiency.

The increase of vibrating frequency can increase the beats of materials on the screen surface, so that the probability of the material going through the sieve could be large, which accelerate the speed of screening materials and improve the screening efficiency. But it will reduce the life of the equipment greatly. For the larger particle sized material, we should choose vibrating screens with a larger amplitude and lower frequencies. For the fine-grained material, we should choose screens with smaller amplitude and a higher frequency. The effect of screening depends on the nature of materials, but different screens for a same kind of material could get different results. For example, the screening efficiency of fixed sieve screening is much lower. For the mobile screen, the screening efficiency is proportional to the movement of screening surface.

We generally use disk vibrating screen to pre-screen the materials or check screening process. For the classification of broken material, we always choose frequent screen, equal-thick screen, and big vibrating screen. we use linear vibrating screen for dehydration and draining process, but for the clearance of sand and mud, the probability banana vibrating screen is a better choice.

In order to improve the efficiency of the vibrating screen, we based on the actual situation, under the premise of meeting product granularity, use a larger screen machines, the larger effective screening area, and the higher screen surface non-metallic sieve surface as far as possible. Choose an appropriate shape of sieve to improve the capacity and efficiency of material particles. Reasonable choice of the vibration motor and adjust the exciting force vibration motors reasonable selection to affect one of the key aspects of the performance of the vibrating screen, vibrating force is the core factors affecting productivity vibrating screen. Furthermore, the vibrating frequency can also influence the operating frequency of the vibrating sieve.Cone crusher is widely applied in metallurgical, construction, road building, chemical and phosphatic industry. Cone crusher is suitable for hard and mid-hard rocks and ores, such as iron ores, copper ores, limestone, quartz, granite, gritstone, etc. The advantages are: reliable structure, high efficiency, easy-to-adjust and economical. The crushing chamber of Rock cone crusher is decided by the purpose of ore, the standard model is suitable for medium crushing; the medium model is suitable for fine crushing and the short head model is suitable for fine crushing.

Cone crusher usually is used in mining ore beneficiation, medium crushing and tertairy crushing. The moving cone liner, fixed cone liner and ore minerials form a three-dimensional abrasivation, so that the liner surface is in a state of complex stress and force. The broken stone gives liner surface a great compressive stress. At the same time, high speed moving cone liner generates huge shear stress. These two kinds of stresses do chisel cut, cutting, and impact extrusion pit on liner board, which is the main force method. Therefore, as for liner material, we requires not only high surface hardness against chisel edge, but also high strength and toughness. As the different working site condition, especially the ore hardness value is different, 3 kinds of stresses systems are also different from each other. At present, we usually choose high-manganese steel as cone crusher liner board.

The nature of the materials, including the hardness, the composition, the viscosity and the moisture content of the raw materials, the particle size and fineness the products require, and so on. The higher the hardness of the raw materials, the more difficult of the crushing work. The crushing ability lowers and the crushing work progress slows down. The longer the raw materials stay inside the machine, the higher the wear and tear of equipment. Therefore, relatively speaking, the crushing efficiency of materials with low hardness is higher than the materials with great hardness, with the yield of the former is also higher. In the crushing production line, if the production materials are uncertain, the workers should try to choose those raw materials with middle hardness, which can improve the crushing progress and product yield in an easier way.

While the crusher employs a laying-type installation, the balancing mass is located at the bottom of the dynamic cone. The prominent features are: main shaft of the dynamic cone is able to bear greater crushing power, the cone body is easy to extract, and it is convenient to change the quick-wear part—the dynamic cone liner, which improves the working environment of the lubrication system as well as promotes the reliability. Compared with these traditional ones, there’s a fundamental change from the MVP cone crusher that it adopts crossing axis rotation, and it has surmounted the problem that the stroke of the feed port of traditional cone crushers is short, ensuring both a sufficient compression stroke for the materials after entering the crushing chamber and uniform distribution of the materials. Therefore, enough crushing force as well as better crushing effect can be obtained.
