Summer is a multiple rainy season, it will affect the work performance and capacity of the concrete batching plant. Especially in some Southeast Asia countries. The air will be moisture because of the rainy weather, We shall take some actions as below to assure the work performance of the plant. 1. Lubrication parts; for example, mixing shaft end. You shall start the lubrication device again even one work shift finished to avoid the rust; 2. cement residue; the cement will be residual on the inner wall of screw conveyor which is used to transit the cement because of the moisture, you shall clean it in time after the work shift finish. If find some unnormal work performance when it is working, you shall stop the plant immediately and check the machinery; 3. Electricity safety. Maybe the cable which is exposed in the air will be affected, please pay more attention to it.

When you choose the concrete mixer, you have to consider several factors. If it is just for a village house, less than 10 rooms, there is not a very strict concrete requirement, and you have enough time to build it, JZC series, JZM series drum concrete mixers are suitable, and they are portable machine. If there is not good electric power supply at working site, JZR series diesel engine concrete mixer is good choice, meanwhile JZR series concrete mixer is also movable with tyres. If you have small projects, totally need 20,000m 3 concrete more or less, JS500 and JS750 are best choice. They are cheap, and also easily be installed and uninstalled. If you already have one small concrete batching plant, the mixer is broken or old type, we suggest JS or HTS series twin-shaft concrete mixers. After all twin-shaft concrete mixers are mainstream now in the world.

The HMC series self-loading concrete batching plant is an ideal plant which is suitable for production of concrete on the toughest jobsite. It is A totally self-contained off-road mobile batching plant which is fast and accurate in dosing and handling material. Because the front cab near the shovel, it is safe and comfortable. With the self compensating loading arm with hydraulic gate and electronic weighing system with load cell, it is being used for high quality concrete. At least 270 degree drum slewing to allow concrete easily to be poured around 360 degree; Fully automated and user friendly.

However, due to such concrete mixer stirring turned mouth inch concrete aggregate have a greater wear. Affect the quality of concrete, and inefficient, has gradually been replaced by compulsory mixer. Compulsory mixer truck drum is stationary and the rotating shaft of the inner drum by the number of the group are set to forced stirring blades, the stirring blades around the vertical axis or horizontal axis of rotation, the material is forcibly stirred until uniform mixing. Such intense agitation mixer, suitable for hard concrete and lightweight aggregate concrete, flowing concrete can be stirred with a good quality mixing, stirring speed, high production efficiency, easy operation and safety, etc.; but the power consumption blades wear quickly, usually need to use high-strength alloy steel or other wear-resistant lining material to do more for centralized mixing station. Concrete mixer compulsory mixer is a versatile mixing machinery, suitable for high-quality concrete mixing operation

At present,with the development of construction industry and the renovation of urban, concrete industry takes on very good prospects. However, a lot of risks are hidden behind the prospects. We have to face that more concrete mixing are built and consequently glut appears. How should we do to avoid these risks and create a better future? Firstly, we must guarantee that the raw material suppliers must be reliable so that we have sufficient supply of material. It is necessary we keep touch with one or more suppliers in case of the shortage of raw material. Sometimes, shortage happens when we have only one supplier, which leads to urgency to find a new partner. Secondly, concrete mixing plants should meet the requirements of nations polices. Our country has always advocated scientific development to support sustainable development and the process of 3 waste so that we can reduce the pollution to environment. Besides, concrete mixing plants should constantly improve their level of science

What issues need to be paid attention to in the use of portable batching plant? The operators should treat safety problems in production seriously. In addition to follow the safety regulations strictly, operators also need to combine the working characteristics of portable batching plant. There are some points we need to follow. Before work, check the wheel in cracks carefully, if there is abnormal sound when tapped with a wooden pine. Make sure the fixed wheel nuts are tightened. After the identification of such problems, after two minutes idling test, the machine can be put into production. In the production of portable batching plant, pay attention to the operation power, or it will cause damage to the wheel and machine easily. After the work is completed, put the operation handle on the neutral position, in order to avoid sudden movements and accidents. When replacing the wheel, the staff should examine it carefully, but he also needs to balance the wheel by using a magnetic chuck.

Concrete pump is equipped with high pressure clean equipment, which can be cleaned quickly and conveniently. Self-lubrication in bucket and cylinder. America PARKER seal parts, very thick chromium coat inside cylinder which makes sure 20,000m 3 concrete output. High low pressure conversion valve with patent, reduce the pressure on main hydraulic system and improve system efficiency with 20%. The followings are the performance characteristics of concrete pump: 1. Triple pump system. There is no mutual interference between hydraulic circuits and system runs normally. 2. Anti-pumping function. It is beneficial to eliminate the fault of pipe plugging in time and stop to feed materials in a short time. 3. Advanced S-pipe distribution valve. It can compensate the wear clearance automatically has good sealing performance. 4. Adopted with wear-resistance alloy materials, the glass-like plate and floating cutting ring have long longevity. 5. Long stroke material cylinder can prolong the service
