concrete mixer starting system and normal operation mode

Since the power of concrete mixer is large, in order to reduce the impact to the power grid, the machine should starting by Y-△(star-delta starting). Besides, it should start with no load and start alternately with the inclined belt. According to the Current number in no-load and full-load, we can confirm if the machine is working well by checking the ampere meter on the manipulate platform. The empirical number of rated current of machine: Amotor power X2. If no-load, the Current is 1/3 A. For example, in HZS180 concrete batching plant, we use SICOMA 3m3. The total power of two driving motor are 110kw, rated Current is 220A. In no-load condition, the Current will be about 70A, and the current should be stable. The normal operating condition: no excessive vibration, no abnormal sound, no oil leakage, no leakage in discharging gate or shaft head. Voltmeter, ampere meter indicates as normal. The highest temperature during running should be less than 80 ℃, the maximum temperature rise

Lubrication and monitoring system in concrete mixer

For the lubrication of the whole concrete batching plant, domestic or imported oil are ok. For China brand, we recommend CHANGCHENG. For imported oil, we suggest Mobil, ESSO, SHELL. BP, etc. For the concrete mixer, there are 4 points to lubricate. The first three are important. 1. The shaft head sealed grease pump: Mobil NLGI 1 or NLGI 2 grease. 2. Reduction gear: Mobil GEAR629 3. Hydraulic station oil tank: Mobil DTE 25 4. Other lubrication points: hinge in the observation door, cylinder pivot point, jackstay in motor base plate, small grease needed every 2-4 weeks. Observe the oil level and oil quality through oil window: oil level should be in the 1/2-2/3 of the oil window. If oil level is too low, please replenish. If oil quality turns bad, please renew it. Please make sure that the air vent in the oil plug (oil filter point) is unobstructed. Otherwise, the air expansion in the oil tank will cause tank leakage. For both lubrication oil and grease, their viscosity will change as the

Sicoma concrete mixer

Concrete mixer is the essence of the concrete batching plant. In China, the concrete mixer standard is (GB/T9142-2000 concrete mixer). The main parameter of the concrete mixer is volume, the unit is liter (L), the parameters are 50,100, ...2000,2500,3000...6000. Generally, people prefer m3, for example 2000 is 2m3. So the common machines that we heard about are 1、1.5、2、3、4 m3, and they are used in the plant HZS60, HZS90, HZS120 ,HZS180 and HZS240. Sicomac concrete mixer shares the most market in China now, it is horizontal shaft concrete mixer. Sicoma concrete mixer has different models, our company (HAMAC) generally will adopt MAO series according to our clients requirement. The machine consists of 7 components. 1. mixing tank 2. mixing shaft 3. connection box 4. monitoring alarm system 5. lubrication-seal system 6. discharging system 7. transmission system Here attached with some photos for you to get acquainted with the Sicoma concrete mixer If you have any questions about si

Different types concrete mixers

The concrete mixer is used to produce the concrete. There are several different types of concrete mixer. Let us explain them one by one. 1. Twin shaft concrete mixer, this is the most popular one in the world. It is being widely used for the concrete batching plant in different countries. For this type forced concrete mixers, we are providing our client with JS series concrete mixer, this is our own brand; SICOMA concrete mixer, this is widely used in the concrete batching plant also. Its price is higher than our own JS series concrete mixer; HTS series European Tech. twin shafts concrete mixer, for this series, its motor is on the top of concrete mixer; 2. Planetary concrete mixer, which is widely used for the semi-dry concrete and fiber concrete. It is more suitable for the precast parts, hollow blocks, bridges etc. 3. JZ series reversing drum concrete mixer. This is a traditional concrete mixer which suitable for the small projects which is without strict quality requirement for the

Information of bolted type cement silo

The cement silos is used to store the bulk cement which is from the bulk cement tank or the horizontal pneumatic cement feeder. It is also can be used to store corn, wheat and fly ash etc. It is equipped with level indicator to show the level and quantity of cement. It is also equipped with air cushion to prevent the cement from caking. For the medium and big volume cement silo, it is too big to be transported. So, we designed the bolted type cement silo. It is easily to be put into the container, be transported in different working sites.

The Reasons of Concrete Pump’s Plugging

Theoretically, the blockage is most likely to occur when three large stones meet in the same section, and the section is mostly occupied by stones, and the flowable area is small. Generally, the maximum particle size of the stone and the inner diameter of the pipe d: D1:3 (Note: This item is specified in the Regulations, according to the conveying height and the type of stone, 1:2.5 to 1:5), and is in the pump A square grid is arranged on the machine hopper to prevent the super-path stone from being mixed in. In the concrete mixture with poor ratio of concrete and poor concrete, the water will penetrate through the aggregate gap, causing the aggregate to coalesce and cause the pipe to block. It often occurs in the pipeline bending, reducing diameter and the middle of the pipeline. In addition, when the concrete water-cement ratio is too large, it is easy to isolate, causing the mortar to separate from the aggregate and blocking the pipe. It is more common in the segregation blockage of
