The breakdowns of crushers in daily life are easy to occur and the solutions are as follows:

1. The temperature of main bearing is too high. May be insufficient grease, then need to add an appropriate amount of grease; If the grease is polluted, it is necessary to replace the grease after cleaning the bearing; If the bearing is damaged, it will need to be replaced.

2. The size of discharging is too large. May be broken teeth wear excessive, then need to replace the broken teeth or surfacing; Replace the edge teeth if they are worn or shed.

3. The vibration of the crusher increases. If the bearing is damaged, replace it. If the gear coupling is damaged, replace it;

4. Reduced capacity or motivation. If the hydraulic coupler leaks, replace the quantitative no. 22 turbine oil or No. 6 hydraulic transmission oil. If the coupler is broken, replace it with a new one. Uneven feed, adjust feed.

5. Cannot automatically reverse. The sensor is not installed correctly or damaged, adjust or replace the sensor; If the sensor lead or wiring position is loose, put on the lead or tighten the wiring position.

6. Sensor protection system fails. If the proximity switch is damaged or the wiring in the electric control cabinet is loose, it is necessary to replace the switch or connect the wires according to the wiring diagram.

In order to keep the crusher in good working condition, reduce the failure rate, improve the work efficiency, extend the service life, we need to do the daily maintenance of the crusher, *** should pay attention to the crusher equipment lubrication maintenance and bearing maintenance, prevent the crusher “strike”.

The hammer head is the key to improve the productivity of the crusher http://m.36332.cn/en/481.html Thu, 30 May 2019 07:08:39 +0000 http://huanqiujx.gotoip11.com/?p=481 Due to the limited length of the extended hammer disk of the crusher hammer head, no matter how big the material block is, it is always roughly knocked off according to the size of the extended length and then further broken. The maximum feed size of this crusher is therefore up to 2/3 of the diameter (or width) of the rotor. The larger pieces of the incoming material, which can be broken in a single stroke, do not need to be supported on the hammer plate, which is obviously different from the case of the rapid hammer crusher crushing the medium-size ore.

In this crusher, the final fracture is between the hammer and the strike plate, the teeth plate, grate. The granularity of final fracture depends on the density of hammer head, linear velocity, shape of counterattack plate and tooth plate, size of coarc of final fracture belt, gap between hammer head and them, and width of labyrinth joint. It has nothing to do with the hardness of the broken material and the filling degree of the material in the crushing chamber. By adjusting the mass of the exciter block, changing the eccentricity distance and changing the speed of the exciter, the crushing force required for any working condition can be obtained. Because it does not have the limit of arc-shaped grate on it, it can discharge the hammer closely, and its final crushing effect is far better than that of slow speed hammer crusher. Pendulum grinding machine can also use this principle, therefore, the material block is in the strong inertial vibration condition, by the pre-set breaking force action, can ensure the density of the material layer due, make the particles bear the pressure in all direction, to achieve the crushing layer. Thus, the advantages of large feeding size, small discharging size and coarse crushing in one machine are obtained.

What are the advantages of mobile crushing mechanism sand production line? http://m.36332.cn/en/479.html Thu, 30 May 2019 07:08:08 +0000 http://huanqiujx.gotoip11.com/?p=479 What are the advantages of mobile crushing mechanism sand production line? Mobile sand – making machine structure compact, reasonable design, small area. No fixed installation for foundation, saving cost. Can move freely, can extend as the material deepens, reduces the traditional material transportation expense. PLC automatic control system, high degree of intelligent automation, one person can operate, but also achieve remote operation. In line with the national requirements for environmental protection, added dust removal and noise reduction device, green production, no pollution. Mobile sand making machine is the product of high technology, more technical input, production cost compared with fixed sand making production line equipment less, the cost is more favorable and reasonable. For limited funds, small amount of small sand mill, the purchase of mobile sand production line is more appropriate. In recent years, there is a shortage of natural sand resources and a shortage of used sand. With the background that sand is difficult to obtain, mechanism sand gradually occupies a foothold in the market and lays a solid market position. A large number of sand and gravel factories have also seen business opportunities into the mechanism of sand production, the formation of a user investment heat. For the new mobile sand production line, small sand mill dare to try to buy sand?

We all know that sandstone aggregate is an important building material, but with the excessive exploitation of natural sandstone resources by human beings, it has been nearly exhausted, causing serious harm to the ecological environment balance. In order to protect the environment, the state has strictly controlled the exploitation of natural sand and strengthened the management of sand mining in river channels. As a result, the price of sand and gravel in various places has skyrocketed and the market is in short supply. The mechanism sand production line has sufficient raw materials, and the mechanism sand produced by technology can effectively make up for the shortage of sand and gravel aggregate in the market. Do you still hesitate to invest in a mechanism sand production line to seize the market business opportunities?

We can according to the user’s production situation and different venues, tailor-made for users to create the most appropriate design, model equipment configuration, quotation budget estimation and other services, so that users do a detailed reference. In addition, in view of the current severe environmental protection situation, our sand production line equipment is also equipped with dust removal device, and external spraying device can effectively control dust transmission. The system is produced by military and wei-dry method, which can also achieve zero discharge of sewage, and will not cause pollution to the local ecological environment. The green and healthy development mode is also in line with the current development strategy of the country.

Benefits of crawler mobile crusher and sifter http://m.36332.cn/en/476.html Thu, 30 May 2019 07:04:04 +0000 http://huanqiujx.gotoip11.com/?p=476 The advantages of crawler mobile crusher and sieve machine are as follows:

The greatest benefit of tracked devices is that they provide a self-contained power supply that enables the device to be deployed to remote locations where line power is not available and can be easily repositioned on the job site. These devices can also be up and running in minutes – as opposed to hours or even days – capturing valuable and valuable time and lost production.

If the engines are used to drive directly a high-horsepower crusher (such as a cone crusher), they also do not require the use of large, cumbersome cables that must be connected to the motor for processing. The devices are also generally safer.

A separate power unit for each unit also increases the flexibility of the separation or separation system and only needs to turn on the engine needed for a particular job, which helps offset the cost of liquid fuel. For example, if you only need to produce 40mm of base material, you are likely to burn less engine and less fuel than producing 20mm of asphalt rock.

Historically, diesel engines have been combined with hydraulic motors and control valves for most tracked systems. This simple circuit eliminates mobile cone crushing stations, expensive starters, cables and connectors.

Then there is the service side. The same mechanism that serves your loader can also serve a crawler crusher or an engine on a screen. Moreover, in contrast to electrical systems, hydraulic systems do not require experienced scientists – or at least skilled workers – to maintain them.

Operating principle of mold temperature machine – water – oil – mold temperature machine http://m.36332.cn/en/474.html Thu, 30 May 2019 07:02:52 +0000 http://huanqiujx.gotoip11.com/?p=474 Mold temperature machine is divided into water type mold temperature machine (water machine) and oil type mold temperature machine, the oil temperature machine) two types, is a kind of heating equipment to provide constant temperature with hot equipment heat source, contains two sets of heating and cooling functions. Widely used in plastic injection, guide plate, die casting, extrusion, extruding, rubber tires, wheel, chemical industry, reaction kettle, mixer and so on all walks of life.

Mould temperature control machine using the equilibrium temperature of thermal equipment, can heat up cool. Mold temperature machine use high heat transfer of thermal conductivity of the media, in a very short period of time will be the temperature with hot equipment to process demands. After the set good thermal equilibrium temperature, can automatically control the temperature within a very small error, and can maintain a constant value. Mold temperature machine by heating cooling system, power transmission system, liquid level control system and temperature sensor, sprue and other devices. The pump to make hot fluid in the power transmission system from within the unit has a built-in heater and cooler to heat equipment, after burning calories with thermal equipment back to internal reheating mold temperature machine, the temperature Sensors measure the temperature of the thermal fluid and sends the data to the control part of the controller, the controller to regulate the temperature of the thermal fluid flow, and indirectly, to regulate the temperature of the heat equipment. If the mold temperature machine in production, the temperature of the heat equipment more than set value of the controller, the controller will open the solenoid valve connected to feed line, until the temperature of the heat transfer fluid, namely the temperature return to set point. If the mold temperature is lower than the set value, the controller will continue to open the heater heating.

The production of die temperature machine configuration should be comprehensive judgement according to the process with thermal equipment situation, if you use the oil temperature machine, the operator must comply with the safety rules: don’t put the mold temperature machine in near sources of heat furnace, joint use with taper leakproof and with heat resistance pressure hose or hard tube, die temperature machine, regularly check the temperature control circuit have joint without leakage, the function is normal, regular replacement of heat conduction oil, should choose a synthetic oil, thermal stability and anti-coking tend to be small. In the use of die temperature machine, select the appropriate thermal fluid is critical. Water as thermal fluid economic, clean, convenient use, once the temperature control circuit such as hose However, water used as heat conducting fluid water also has disadvantages: low boiling point of water, which limits its service temperature. Water temperature machine can be divided into three types: water temperature machine at 120℃, water temperature machine at 150℃ and water temperature machine at 180℃. When using water as a heat conduction fluid, should consider the following precautions: use rust preventer advance processing temperature control loop, use before water inlet filter, wash water temperature machine with cleaning agents and on a regular basis with thermal equipment. The use of higher temperature, the oil temperature machine up to 350 ℃, boiling point of the oil is high, but the heat transfer coefficient of heat conduction oil only 1/3 of the water.

The use of mold temperature machine, water mold temperature machine and oil mold temperature machine can improve the forming efficiency of products, reduce the occurrence of defective products, improve the appearance of products, restrain the defects of products, speed up the production schedule, reduce energy consumption and save energy.

How the chiller works http://m.36332.cn/en/470.html Thu, 30 May 2019 07:00:11 +0000 http://huanqiujx.gotoip11.com/?p=470 Chiller commonly known as freezer, refrigerator, ice water machine, freezing machine, cooling machine, etc., due to the use of all walks of life more widely, so the name is also more numerous. The principle of its properties is a multifunctional machine that removes liquid vapor through a compression or thermal absorption refrigeration cycle. The steam compression chiller unit consists of four main components of the steam compression refrigeration cycle compressor, evaporator, condenser, and part of the metering device in the form of which different refrigerants are realized. Absorption chiller USES water as refrigerant and relies on water and lithium bromide solution to achieve strong affinity of refrigeration effect.

Chillers are commonly used in air-conditioning units and industrial cooling. In air-conditioning systems, chilled water is usually allocated to heat exchangers or coils in air treatment units or other types of terminal equipment for cooling in their respective Spaces, and then the cooling water is redistributed back to the cooling that has been cooled. In industrial applications, cooling pumps for frozen water or other liquids are used through processes or laboratory equipment. Industrial chiller is used to control products, machinery and plant machinery cooling in all walks of life.

Air cooled chiller

According to the form of refrigeration, the chiller can be generally divided into water-cooled type and air-cooled type. In terms of technology, the water-cooled kCAL /h is 300 to 500 higher than the air-cooled energy efficiency. In terms of price, water cooling is much lower than air cooling; In installation, water cooling should be incorporated into the cooling tower for use, and air cooling is movable without any other assistance. However, the air cooling chiller only USES the fan to dissipate heat, which has certain requirements on the environment: for example, ventilation, humidity, temperature not higher than 40°C, ph value of air…

Calculation method of chiller http://m.36332.cn/en/468.html Thu, 30 May 2019 06:59:34 +0000 http://huanqiujx.gotoip11.com/?p=468 How to choose the most suitable industrial chiller? In fact, there is a very simple formula:

Refrigerating capacity = refrigerating water flow *4.187* temperature difference * coefficient

1. Flow rate of frozen water refers to the flow rate of cold water required by the machine at work. The unit shall be converted into litres/second;

2. Temperature difference refers to the temperature difference between the inlet and outlet of the machine;

3, 4.187 is quantitative (specific heat capacity of water);

4. The coefficient of multiplication is 1.3 when choosing the air-cooled chiller, and 1.1 when choosing the water-cooled chiller.

5. Select the corresponding machine model according to the calculated cooling capacity.

But the most important thing is to know the rated cooling capacity (9.07KW) and then choose a 3P machine. And so on. So the most important choice of industrial chiller is to figure out the rated cooling capacity
