Ore washing mixer

1. Turn off the power. It's safe. The cleaning methods are as follows:
1. Break the steamed bread into small pieces and put it into the blender
2. Close the lid of the mixer, turn on the power and stir for half a minute
3. When the steamed bread pieces turn into steamed bread resie, pour out the resie, you will find that the oil in the blender is sucked off, and the inner wall and blade of the blender are not so greasy
4. Rinse the mixer with running water again, and it will be very clean.

2. 1. Pour a few drops of detergent and appropriate warm water into the mixer, or use cold water, but warm water can more effectively decompose the grease and help remove the grease; If cold water is used, it may need to be repeated twice to achieve degreasing effect
2. After that, start the blender and let it start mixing the detergent with water in it. It only takes a few minutes
3. After the mixer stops operation, turn off the power. Take out the mixer, rinse it with clean water, and check it again. If there is still dross or greasy feeling, repeat the above action until it is clean. Finally, turn the mixer upside down to dry.

3. Mixer, pulverizer difference: mixing is to mix different substances together to make it uniform; And the crusher is to crush the big material into small pieces. It has different functions, but it can be mixed in practice
blender is a kind of machine with blades rotating in the cylinder or tank to mix a variety of raw materials into a mixture or suitable consistency. There are many kinds of mixers, including forced mixer, single horizontal shaft mixer, double horizontal shaft mixer and so on. Note: mixer and automatic feeder must be cleaned inside, especially in winter, so as to prolong service life. Mixer is a mixer, because the usual function of mixer is to mix all kinds of dry mortar, so it is commonly known as mixer
crusher is a kind of machine which can crush large size solid raw materials to the required size. The crusher is composed of coarse crushing, fine crushing, wind conveying and other devices, which achieve the purpose of the crusher in the form of high-speed impact. Using wind energy to form powder at one time, the traditional screening procere is cancelled. Mainly used in mining, building materials and other instries.

4. It's better to use the three blade roots blower with slightly higher pressure. We used two roots blowers to replace the blender in Xinjiang metal mine at first, and the beneficiation effect was very good. Later, we replaced them all. At first, the fan from Changsha was more expensive, but later, we used Jingong roots blower all the time. The mixing effect is obviously more uniform than the blender, and it also saves electricity. It's suggested that colleagues try it.

A large amount of slurry wastewater is proced in the mine washing operation, which makes people complain incessantly. The local environmental protection departments pay more and more attention to the zero discharge index of instrial and mining enterprises. How to deal with this kind of high concentration slurry and what kinds of dehydration equipment are on the market? This is what most instrial and mining owners want to know, At present, the equipment for mud sewage treatment on the market include belt filter press, frame filter press, box filter press, centrifugal sludge dewatering machine, etc., but not all dewatering equipment are suitable for the treatment of sand washing mud water in ore field. This kind of mud has high concentration and heavy ratio, and the efficiency of traditional shovel digging and natural drying method is extremely low, which is not easy to treat. For example, e to the structure of belt type and box type filter press, the separation of mud and water must rely on filter media (filter plate and filter cloth), but the mesh of filter media in the current market can not be as small as mud particles, so we can only increase the dosage of reagent to make up for this lack, and non coagulation greatly increases the operating cost of the equipment

I. dosing cost of mud treatment equipment:

working principle of washing sewage treatment equipment: according to the different proportion of materials, after the sewage enters the centrifuge, the solid particles are dropped onto the wall of the drum through the high-speed rotation of the drum, and the mud wall is continuously formed at the mud outlet through the forward extrusion and scraping of the screw pusher, and the water flows back to the outlet, The sludge is pushed out to the sludge outlet. There is no filter cloth in the whole machine. It only relies on centrifugal force to separate mud and water. The requirement for dosage is very low. A 350 type centrifuge works for 8 hours a day, and the dosage is 1-3kg. Depending on the sludge, the centrifuge can even achieve better treatment effect for many materials without dosing. This greatly reces the cost of dosing and treatment. Because of the large mesh of the filter belt of the belt filter, the requirement of mud burst flocculation is high ring dewatering, which leads to the increase of dosing cost. A certain amount of flocculant needs to be added into the concentration tank when the plate and frame machine is used for treatment

Second, the long-term cost of mud treatment equipment quotation:

the power consumption of the centrifuge is three to four kilowatts higher than that of the belt machine when it is in use, which is 30 yuan more per day when it works eight hours per day. However, the centrifuge does not need to be washed with water ring the whole dehydration process. The belt type machine is different. A one meter belt type machine needs 60-70 cubic meters of water to backwash the filter belt every day. The backwashing water is refluxed and reprocessed, and the treatment cost of 2.5 yuan per cubic meter of water (the dosage is larger than that of centrifuge) will increase by at least 150 yuan per day. For example, the cost of backwashing with tap water is higher, which can save 120 yuan per day and at least 40000 yuan per year. The filter cloth must be cleaned after the sludge is treated by the plate and frame machine, otherwise the treatment effect will be affected, the treatment time will be prolonged, and it will be time-consuming and laborious. Secondly, the plate and frame filter press has pressure requirements for the feed pump. The tailing mud including tailing mud contains part of fine sand particles to a certain extent. This part of fine sand makes the blade wear cycle of pulp pump shorter under high pressure flow rate, the pump is easy to be damaged, and the price of high pressure pump is high

The sludge formed in the sedimentation tank was fed into the horizontal screw settling centrifuge, and flocculation was carried out ring the process

III. adaptability of mud treatment equipment price to sewage property:

the mud dehydrator of sand washing field has strong adaptability to sewage property. No matter what kind of sewage, it can adapt to treatment. Some can be treated without adding chemicals, and some can be treated with a small amount of chemicals. Especially for some sludge with oil, fat and stickiness, the other two kinds of equipment are very difficult to complete. Filter cloth is easy to be blocked by sludge, sludge particles are too fine, oily and viscous, so it is not easy to deal with. The separation principle of centrifuge is to separate mud and water by centrifugal force and rapid gravity sedimentation based on the specific gravity difference between mud and water. It doesn't rely on any filter medium, and the whole machine doesn't have any filter cloth, so it can run stably

Four, mud treatment equipment area:

a 350 model covers only 3.5 square meters, a one meter belt machine covers an area of 6-7m2, which is larger than the centrifuge, and a plate frame covers an area of more than the centrifuge, especially for some units with short plant area, it is more suitable to save the use of the site. And according to customer requirements can be made car type mobile operation. This operation mode is particularly flexible and simple for the treatment of piling mud in construction sites and the dewatering in river dredging engineering. Due to the limitation of plate frame and belt dewatering mode, it can not meet the requirements of vehicle mounted mobile operation

5. Installation of mud treatment equipment:

the centrifuge is very convenient to install and does not need to be fixed by low foot screws. The ore washing instry only needs to make a common foundation (steel structure or brick concrete structure) to put the equipment on and connect the feed pipe and power supply to run. Because of the large volume of belt filter press and plate and frame filter press, the regional capital construction cost of dehydration is relatively high

6. Operation of construction mud treatment equipment:

continuous feeding and discharging of centrifuges, automatic sludge discharge, one person can operate multiple centrifuges at the same time, with low labor intensity. The whole dehydration process is carried out in a closed state, and there will be no mud splashing. The belt filter and plate frame machine are carried out under open condition, so the whole environment is not ideal. The plate and frame machine needs manual assistance to discharge sludge after long-time drying. Taking a 200 square plate and frame machine as an example, in order to improve the work efficiency, a single machine needs to be equipped with two workers to discharge sludge at the same time, which is time-consuming and laborious, and the operation process is cumbersome

7. Quotation and maintenance of mud treatment equipment:

the main vulnerable part of centrifuge is bearing. At present, our company adopts SKF Bearing imported from Germany, and the replacement cycle is generally more than two years. The whole equipment is of steel structure, and the easily worn parts are lined with tungsten steel, so as to fundamentally solve the problem of fine particle wear. The filter cloth, plate frame and pump of belt filter and plate frame filter press are easy to be damaged. The price of a piece of filter cloth is more than ten yuan per square meter. According to the material load, it needs to be replaced in about two months. As most ore mills and concentrators are open-air operation, the operation environment is harsh, which is easier to accelerate the aging of filter cloth and filter plate and greatly shorten the replacement cycle. The belt type machine is open, some transmission parts are directly in contact with sewage ring operation, and the foundation foot frame is easy to be corroded and skewed after long-term operation (this situation can not be repaired), which leads to the opening angle of the contact surface of the filter belt is not parallel, the filter cloth is deviated, the dryness and humidity of the sludge after dewatering are uneven, and it is difficult to transport, the price of replacing the filter belt is high, and the maintenance cost is increased

summarize the advantages of mud treatment equipment:

large treatment capacity, long wear-resistant service life, reasonable structure, low noise, small floor area, wide range of application, simple operation, convenient maintenance, high degree of automation, stable operation, low equipment cost and low capital construction cost

6. The main machine of the concrete mixing plant should be cleaned after use every day. If the cleaning is not clean or clear, it will cause concrete accumulation in the mixing bucket, increase the failure rate of the main machine and rece its service life, Therefore, great wall construction machinery summarized some cleaning essentials and precautions for the main machine of the concrete mixing station
the cleaning essentials of the main machine of the mixing station are as follows: only a small amount of stones and water are added to the mixing machine, which is stirred in the mixing barrel for 5-10 min, and all materials in the machine are removed after cleaning, without water and accumulation; After shutdown, the pipeline shall be washed to remove the st inside and outside the mixing tank and the adhered concrete
in general, JS1000 mixer can add about 150-180 kg of water. Other types of mixer can increase or decrease the amount of water according to the amount of water added. They can also provide their own high-pressure water gun for cleaning. Precautions for cleaning the main engine of mixing station:
I. before cleaning, the power supply and gas path must be cut off, the resial gas must be discharged, and the control room must be locked
2. When manually cleaning the mixing drum, it is strictly forbidden to strike the mixing shaft, mixing arm and mixing blade violently
thirdly, if the waiting time is too long in the mixing process, water should also be added for simple cleaning of the mixer (especially in summer, the waiting time is more than 20 minutes).

7. When cleaning the concrete mixer, the following matters should be paid attention to:
1. Matters needing attention for cleaning the concrete mixer:

regularly carry out the maintenance of the items specified in the maintenance proceres, such as cleaning, lubrication, refueling, etc

2. Precautions for cleaning concrete mixer 2:

before starting the concrete mixer, check whether the controllers are in good condition. After the shutdown, pour water and stones into the mixing drum for 10 ~ 15 minutes for cleaning, and then remove the water and stones. If the operator needs to enter the mixing drum for cleaning, he should not only cut off the power supply and remove the fuse, but also lock the switch box

3. Precautions for cleaning concrete mixer 3:

it is forbidden to remove the concrete accumulated in the concrete mixer barrel by hammering, but only by chisel

4. Precautions for cleaning the concrete mixer 4:

in the severe cold season, after the work is completed, the mixer drum should be cleaned with water and the water in the water pump, water tank and water pipe should be drained to avoid freezing damage of the water pump, water tank and water pipe.

8. 1. After using the mixer for a period of time, if you find that the switch button is not flexible, you can inject a few drops of edible oil for lubrication
2. When cleaning, first pull out the power plug, take out the cutter, separate the tank bottom from the tank body, wash the cutter and the tank body with washing liquid or clean water, and wipe the dirt on the surface of the tank bottom with a wet cloth only. It is strictly forbidden to wash in clean water to prevent damage to the machine
3. Do not use other accessories and tools without the permission of the manufacturer
4. Easy to stir food can choose high speed stirring, difficult to stir food can choose low speed stirring.
