Detailed Explanation of Grow Rack Ventilation Solutions

The grow rack technology provides convenience for plant lovers, but the temperature and humidity control of the grow rack is particularly important for plants. Too high or too low temperature and humidity will affect the planting quality and even cause diseases and insect pests. If some effective measures can be taken to make the ventilation and cooling effect of the grow rack better, and at the same time reduce its operating cost, the ventilation system will become a link that consumes a lot of energy for the grow rack.

How to control the temperature of the grow rack?

It is mainly adjusted by means of ventilation and heating, that is, a ventilation system, to ensure the necessary ambient temperature required for the growth of plants. The cooling of the grow rack is mainly through the exchange of air inside and outside the frame, and ventilation to adjust the internal temperature.

Fan forced cooling system is the best cost-effective

When choosing an evaporative cooling method (wet pad-fan cooling system, spray humidification and cooling system), it is necessary to make a technical and economic comparison of the “one-time investment and operating costs” of each plan, and minimize the total cost as the goal of the optimization plan. At present, the fan forced cooling system has become the most widely used ventilation and cooling system. This system is combined with a special axial flow fan for the greenhouse and a wet curtain, and the ventilation is fast and the temperature is cooled very quickly. After many experiments, it has been shown that the fan forced cooling system has become a cost-effective ventilation and cooling solution with good cooling effect and low cost.

What are the vibrating screen techniques?

The process in which the broken material is divided into different particle sizes through one or several layers of sieve surface is called sieving. The vibrating screen is a vibrating screen that uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide sand, gravel, crushed stone and other materials into different grades according to the particle size.

The vibrating screen screening process is generally continuous. After the screening raw materials are fed to the vibrating screen machine (referred to as the sieve), the materials smaller than the sieve size pass through the sieve, which is called the under-sieve product; the material larger than the sieve size passes through the sieve. Continuous discharge on the surface is called over-sieve product.

Vibrating screen machinery is a necessary auxiliary equipment in mine crushing and sand making production lines, and its selection has an important impact on the particle size and grading of the final product.

Factors to be considered in vibrating screen selection:

High frequency dehydration vibrating screen

The characteristics of the sieved material (the content of the size of the material under the sieve, the content of the size of the difficult-to-sieve particles, the content of moisture and clay in the material, the shape of the material, the specific gravity of the material, etc.);

The structure of the vibrating screen (screen area, number of screen layers, size and shape of the screen hole, area ratio of the screen hole, motion mode of the vibrating screen, amplitude and frequency, etc.);

Requirements of beneficiation process (processing capacity, screening efficiency, screening method, vibrating screen inclination), etc.

In addition to considering the above effects, the following basic principles should also be observed:

(1) After determining the sieving area, the width of the sieve surface should be at least 2.5 to 3 times the size of the largest piece of material to prevent the sieve from being blocked by large pieces of material.

(2) In order for the sieve to be in a good working condition, the ratio of the length to the width of the sieve should be selected within the range of 2 to 3.

(3) Reasonable screen material and structure suitable for working conditions should be selected.

How to deal with the severe wear of the hammer head of the crusher?

The hammer head of the crusher is an important part to ensure the normal production of ore materials. It not only affects the output of sand and gravel aggregates, but also affects the quality of finished products. Many users are deeply troubled by the serious wear of the hammer head. So how to deal with it? In response to this problem, the crusher manufacturer gave us a detailed introduction.

Why choose a crusher with a hammer head

There are so many types of crushers on the market, including crushers with hammers and crushers without hammers. Some people say that since the hammer head is often worn, it is better to choose a crusher without a hammer head. In fact, although hammer crushers have the trouble of wear and tear, other crushers also have wearing parts, but they are not hammer heads.

Common crushers with hammers on the market include: impact crushers, hammer crushers, fine crushers, vertical compound crushers, etc. This kind of crusher with a hammer is generally an impact crusher. The aggregate produced has a better particle size and will be broken along the gaps in the ore. There are few cracks in the particles. The finished product is often cubic and has a high degree of gradation. Therefore, Many people will choose this kind of impact crusher with hammer head.

Reasons and solutions for the serious wear of the hammer head of the crusher

Vertical compound crusher

In order to solve the problem of serious wear of the hammer head of the crusher, it is necessary to find out the cause of the serious wear of the hammer head of the crusher and prescribe the right medicine. The main reasons for the serious wear of the hammer head of the crusher are the material of the hammer head, the manufacturing quality and structural design, the technical design of the crusher, the feeding situation and the clearance of each part of the structure.

Reason 1. Hammer head material

The hardness and toughness of the hammer head are one of the reasons that affect the wear of the hammer head. Generally, the greater the hardness, the greater the wear resistance of the hammer head, but as the hardness increases, the impact toughness of the hammer head will decrease. Therefore, the key to improving the wear resistance of the hammer head is to find a material with both hardness and good toughness.

Treatment method: choose the hammer head of high wear-resistant material, such as high manganese steel, high chromium cast iron, low carbon alloy steel, etc.

Precautions for operation of main components of linear vibrating screen

Linear vibrating screen is generally composed of vibrator, screen box, support or suspension device, transmission device and other parts, and is mainly used in mining, coal, smelting, building materials and other industries. The working conditions of the linear vibrating screen are relatively harsh, and various failures often occur during operation. In response to these problems, the vibrating screen manufacturer gave us the following detailed explanations on the key points of operation and maintenance of the main components of the linear vibrating screen.

1. Adjustment of the eccentric block of the exciter

1) The size of the exciting force is closely related to the movement of the screen machine. There are 8 adjustment holes between the main block and the counterweight block of the eccentric block,which are equally divided by 15°, so it can be adjusted according to 8 positions at different angles. After being adjusted to different positions, the centrifugal force changes, and the vibration amplitude of the screen machine is changed accordingly.

When adjusting, each vibrator needs to be adjusted synchronously. If the adjustment position is different, the exciting force generated is different, and the material on the screen surface will jump irregularly. Therefore, correct adjustments must be made, especially when the exciter is replaced. When using the vibrator, the position of the adjustment hole must be consistent.

2) Inspection after adjustment, it is required that the two symmetrical points on both sides of the screen have the same amplitude and direction. If there is a slight difference in the amplitude of the two sides of the screen machine, no more than 0.5mm is allowed, because the movement track of the material is related to the uniformity of the material on the screen surface, and it is necessary to adjust the distribution of the incoming material in time.

2. Coupling

The vibration exciters on both sides of the screen machine are connected by universal couplings. When replacing them, attention should be paid to the straightness of the joint surface of the universal couplings. The universal coupling has been dynamically balanced before leaving the factory, and the straightness of the coupling is directly related to the vibration amplitude of the screen machine.

When replacing, use the method of natural sagging of the eccentric block of the exciter, and then connect and fix the universal coupling with the coupling of the exciter. The difference in screw hole position is adjusted by adjusting the position of the spline. One thing to note is that the length dimension of the coupling and the length dimension of the spline should be selected reasonably to avoid insufficient coupling length or spline jamming.

High frequency dehydration vibrating screen

3. Rubber buffer spring

Each rubber buffer spring can be used for about 15 to 20 months, and the size varies with the model of the screen machine. The temperature of the equipment cannot exceed 45°C when it is running. When replacing the rubber spring, attention should be paid to the elastic coefficient, that is, the height of the rubber spring at the inlet of the screen machine is similar to that of the outlet, so that the buffer rubber spring can be used reasonably and not easily damaged.

Also, when replacing the rubber springs, it should be noted that the rubber springs on the front and rear parallel lines should be replaced at the same time to avoid amplitude changes due to inconsistent aging of the rubber springs.
