Use of concrete mixing station

When construction on cement stabilized soil you should obey the following requirements:
1) The clod must be smashed as much as possible and the diameter should not be more than 15mm.
2) The batching proportion should be accurate.
3) The cement should be paved evenly during the road-mixing construction.
4) Watering and mixing should be well-proportioned.
5) The base thickness and elevation should be controlled strictly and the camber slope should be consistent with the surface.

6) When the mixture is at or slightly larger than the optimum water content (it can be 1%-2% larger on hot days ) compact until it reaches the lowest compaction degree confirmed by heavy compaction experiment.

1Installation
Installation site should be plain and well-grounded. The pithead should be higher than ground to prevent the water inflow.
Lift the mixer with lifting device and install four supporting legs connecting angle inclined strut ladder and the downward track. Then place the mixer in the appropriate place of the pit.
2Inspection and preparation before test run:
Check if the connection of the motor and electric element is steady. 
Check the connecting bolts between two parts (especially the moving parts) and ensure they are firm
Check if there are sundries stuck in mixing canister and track rack.
3No-load test run
Start mixing motor. At the same time the running direction of two mixing shafts should be same with indicating direction of the signs . If there is any difference change the power connection.
4Over-load test run
Shut down the discharge door and lift the hopper after feeding. Ensure that the hopper can run steadily and stop on the track freely. If there is slipping you should put the hopper into the pit bottom then adjust the big nut in brake motor.

Concrete mixing plant price

Concrete mixing station has a lot of businesses in the sale , the price is not the same , and why some low price of some prices high? In addition to some of the reasons on what caused the material cost price ?
Prices there are a lot of factors , such as advertising costs, labor costs , the price of products sold in each region is not the same , there are some sinister business use of waste materials to reduce costs do not say.Buy good quality and low prices of mixing station , go xinfeng machinery.
     

Mixing concrete common problems and solutions

Concrete quality common fault of the prevention and control of application has become an indispensable part of the concrete construction, mixing process of concrete mixing plant in the often prone to or this or that problem, bring trouble to the construction progress and construction quality.Now is often the cause of the problem analysis of mixing concrete, and gives a series of solutions.
Pumped concrete slump loss, slump instability problem of reason and solution1, the reasons causing
(1) the concrete admixture and cement concrete slump loss caused by bad adaptability.
(2) the concrete admixture content is insufficient, retarded, plastic effect is not ideal.
(3) the hot weather, some admixtures failure at high temperature;Moisture evaporates quickly;Bubble spillover caused fresh concrete slump loss.
(4) the initial concrete slump is too small, the unit water consumption is too little.
(5) the site and mixing plant coordination is bad, make the tank car needed, traffic jam, time is too long, lead to concrete slump loss is too big.
(6) concrete mixing measurement error is large, the weighing system was unstable.
(7) the coarse and fine aggregate moisture content changes.
(8) cement mixing warehouse storage, mixed use.
2, solutions
(1) adjust the formula of concrete admixtures, to make it compatible with cement.Before construction, be sure to do concrete admixtures and cement adaptability test.
(2) adjust the concrete mixture ratio, increase or reduce the sand ratio and water consumption, adjust the concrete initial slump to more than 200 mm.
(3) adding suitable amount of fly ash to replace partial cement.
(4) the right amount increase dosage of concrete admixture, admixture of adjustment of condensed (especially in temperature is much higher than normal temperature).
(5) to prevent moisture to evaporate too fast, bubbles spillover too fast.
(6) is chosen or pozzolana cement slag cement.
(7) to improve the concrete carrier of water and cooling device.
(8) the precision of the measuring equipment shall meet the relevant provisions, and has a valid certificate, issued by the legal metrology department strengthen self-checking, ensure measurement accuracy.
(9) to strengthen the aggregate moisture content inspection, change, timely adjust the mixing proportion.
(10) into the library cement should press manufacturers, varieties and label storage, use, respectively.
3, summarize experience
Especially for pumping concrete pumping and pouring underwater concrete pile foundation concrete slump loss problem.Through learning test summarizes a set of solution to the problem combined with the actual situation.Such as communication admixture manufacturers to improve and adjust the admixture of slow condensed;Adjusting the construction time of concrete, try to avoid not in high temperature circumstance construction;In the case of poor construction road traffic road far adopting admixtures secondary feeding;Use of concrete with high volume of fly-ash is construction, etc.Make the vexed question of concrete slump loss, get bigger.Whatever the reason lead to the slump caused not pumping or smaller to meet the construction requirements we can use the slump of admixtures to adjust to the slump, put an end to arbitrary water increase slump of bad habits radically determine the quality of the concrete.

Price and model of mixing plant

  What kind of commercial concrete batching plant models do we have?How about the price of HZS120 concrete mixing plant?It is almost the lunar new year in China, some companies have took their holidays,however,Zhengzhou Xinfeng machinery is very busy, because three group of customers are going to visit our company,and a group of customers from Suzhou, Jiangsu province just left, the customer from Zhangye, Gansu province arrived,and in the afternoon,we received our customer from Yulin,Shanxi province,several business managers are very busy accompanying the customers to visit the workshop,thankfully,two customers sign the contract, the other customer is going to sign the contract after the Spring Festival,but they have already decided to work with our company.

Why is Xinfeng machinery so popular?First of all, Xinfeng machinery is a company with more than 20 years history and has rich production experiences and technologies, we can also customize the machine according to different user requirements.Second,Zhengzhou Xinfeng machinery has perfect pre-sale, sale, after-sales service system so that our customers can buy our products rest-assured.Finally, some customers may have insufficient funds,so Zhengzhou Xinfeng machinery launched favorable activities for example payment by installment, our customers like this action, some customers came for our brand "Xinfeng", this explains Xinfeng machinery has been firmly established in the market.
 
So,What kind of commercial concrete batching plant models do we have?Zhengzhou Xinfeng machinery have large, small and medium sized concrete mixing plant which can meet the needs of different users, such as small HZS25,HZS35 to HZS50 mixing plant and the medium size are HZS60 HZS75,HZS90 mixing plant, etc.we have large mixing plant such as HZS120,HZS180, even double HZS120,HZS180mixing plant etc.The mixing plant is suitable for commercial concrete, engineering use.It can be widely used.So, how about the price of HZS120 station?A set of more than one hundred and forty thousand, you can consult the online customer service for specific price.
 
 The concrete mixing plant of Xinfeng machinery are designed by high-tech talent.It has a high degree of automation, convenient operation and long service life of wearing parts.Our company has long-term cooperation with China railway 16th bureau, China railway 14th bureau and provides the high quality concrete for infrastructure construction in our country.
