Scrap metal classification drum screen with best priice

drum screen is a mechanical screening device used to separate materials like soil, mulch, and sand, ore, coal, gravel, mainly in the mineral and solid-waste processing industries, also called rotary screen or drum screen. The products were exported to Thailand, Indonesia, South Africa, Australia, Europe, etc.

At present, the rotary drum screen used in compound fertilizer plants is composed of a central shaft, a connecting rib, and two sieve barrels and sieve cores with different apertures. If a fault occurs during the production process, maintenance is difficult and the maintenance cost is high;
Traditional drum screens have two main disadvantages
1. Rotary classification sieve consists of stainless steel sieve and stainless steel sieve. After damage, the whole sieve or sieve must be replaced. The cost of replacing a set of sieve is up to 100,000 yuan, and the cost of the sieve cylinder is more than 20,000 yuan.
2. The sieve holes are easily blocked, difficult to clean, and the classification effect is poor.rotary drum screen

Manufacturer of new drum screens

The purpose of the utility model is to solve the above-mentioned shortcomings of the existing rotary classification sieve, and provide a rotary classification sieve for producing compound fertilizer. The outlet sections are connected to each other. The sieve hole diameter of the middle section is larger than the sieve hole diameter of the inlet section and smaller than the sieve hole diameter of the outlet section. The center shaft 1 is fixedly connected to the sieve barrel through a set of connecting ribs.
The advantages of the new practical drum sieve are: 1. The double-layer rotary classification sieve is changed to a single-layer sieve, which simplifies the structure and reduces the investment in equipment. , Can be repaired in sections. 2. Three different pore sizes are set on the same sieve cylinder, the sieving and classification are finer, the sieving effect is good, the sieve holes are not easy to be blocked, and the output can be increased by about 20%.

Sandblasting nozzle classification and use

Using high-pressure air as a power source to drive abrasive particles to hit objects within a certain range will produce a great impact. The function of the sandblasting nozzle is to spray abrasive particles on the object evenly and efficiently. Sandblasting nozzles can be divided into: straight hole sandblasting nozzle, Venturi sandblasting nozzle , double Venturi sandblasting nozzle, angle sandblasting nozzle Straight hole nozzle: There are only contraction section and straight section inside, the structure is simple and easy to manufacture. This kind of nozzle cannot overcome the vortex phenomenon existing at the inlet end, and the pressure loss is large; the abrasive velocity at the outlet is less than 100m/s under the pressure of 0.7MPa.

Working principle and parameters of industrial slurry pump

In order for the industrial slurry pump to fully play its role, we need to understand the working principle of the industrial slurry pump: https://www.lzzgmachine.com/products/supporting-equipment/slurry-pump.html Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy to leave the outer edge of the impeller at a high speed and enter the volute pump shell. In the volute pump case, the Fluid is slowed down due to the gradual expansion of the flow channel, and part of the kinetic energy is converted into static pressure energy. At last, it flows into the discharge pipe and is sent to the place where it is needed. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller. Above the liquid level of the storage tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. LZZG slurry pump pe...

The difference between quartz and mica

Mica and quartz are common minerals that play an important role in mineralogy. Although they are both silicate minerals, there are clear differences between them. First, mica and quartz are very different in appearance. One of its distinguishing features is that mica exhibits a layered structure that can be easily peeled off into thin flakes. Quartz, on the other hand, is a uniform crystal with no layered structure. Additionally, mica is usually dark in color, such as black, brown, or green, while quartz is usually clear or white. Secondly, mica and quartz also differ in their physical and chemical properties. The hardness of mica is usually between 2.5 and 4, which is relatively easy to be scratched; while the hardness of quartz is very high, 7, which is a very hard mineral. In addition, mica has good refractive properties and electrical properties, while quartz is an excellent piezoelectric material.
