How to Maintain Concrete Mixing Plants in Winter

2024-08-15

When winter comes, the weather is getting colder and colder, but the use of concrete mixing station will not stop. However, when the temperature is low in winter, attention should be paid to the maintenance of concrete mixing station. So how should it be maintained in winter? 1.After the concrete mixing station is shut down, it is necessary to discharge all the liquid in the water tank from the water pump, water tank and admixture as soon as possible, so as to prevent the water from freezing due to the damage of the residual machinery and pipelines in the water tank, or the startup can not be started normally. 2.Concrete mixer to stop working for more than 4 hours should be compressed water and air bag water row, prevent water condensation after compression. 3.Diagonal belt if there is a sprinkler or belt conveyor idling should allow a period of time after the end of production, the cleaning belt scraped to the surface of the water, prolong the service life of the belt conveyor, vertical tension weight should be reduced and...

The Advantages of Hopper Type Concrete Mixing Station

2024-08-14

Hopper type concrete mixing station is a kind of building material manufacturing equipment which integrates material weighing, conveying, mixing and control system. It is mainly composed of main mixer, material weighing system, material conveying system (especially hopper), material storage system and control system. These systems work together to accurately weigh, transport, mix and stir cement, aggregate (such as sand, stone, etc.), water and other materials, and finally make concrete that meets the requirements. Skip loading concrete mixing plant has the following advantages: I. Small Footprint and Easy Installation 1. Hopper concrete mixing stations typically adopt a modular design, making their footprint relatively small and the installation process more convenient. This design not only saves space but also enhances the mixing station's ability to adapt to various complex environments, allowing for rapid deployment. 2. The main body of the mixing station occupies an area of less than 200 square meters at a minimum, which helps project parties fully conserve land resources and use the station even in extremely compact environments. 3. Installation is quick and convenient. With foundational work completed, a...

The Difference Between Integral Cement Silos And Sheet Cement Silos

2024-08-13

Cement silo is a kind of closed silo for storing materials, which can be divided into bulk cement silo and sheet cement silo. Both of them are containers for storing bulk materials, and both of them play an important role in both warehousing and engineering construction. As a manufacturer specializing in the production of mixing station equipment for more than 20 years, the auxiliary machinery introduces the differences and advantages between flaky cement silo and bulk cement silo with years of accumulated experience. 1. The Device The characteristic of bulk cement silo is that it can be directly transported to the construction site and then welded. However, the sheet cement silo is different. The sheet cement silo is not a complete device. Before use, it is necessary to assemble the sheet cement silo, and then the installed sheet cement silo can be welded on the foundation. 2. Transportation The functions of bulk cement silo and sheet cement silo are complementary, and the transportation of bulk cement silo is relatively troublesome, but the bulk cement silo is more favorable in price...

How to Do Daily Maintenance of Inclined Belt and Flat Belt in Belt Concrete Mixing Plant

2024-08-08

In belt concrete mixing stations, flat belts and inclined belts (hereinafter collectively referred to as belts) are used to transport aggregates during work, which greatly improves the efficiency of the entire mixing station's automated production process. Once a problem occurs, the entire production task must be interrupted. Therefore, it is very important to master some common belt fault handling methods and daily belt maintenance. Let's talk about this topic together today. In general, the concrete batching plant belts are divided into flat belts and inclined belts. The flat belt is under the batching bin and is responsible for transporting raw materials such as aggregates to the inclined belt, while the inclined belt is responsible for transporting raw materials to the middle bin of the mixing host. The working methods of the two are also the same, so let's explain the common faults of the inclined belt in detail below. I. Common Faults 1. Belt Deviation Belt deviation is the most common fault phenomenon. The reason for its occurrence is that the belt is subjected to unbalanced force in the width...

The Difference Between Bucket-lifting and Inclined Belt Conveyor in Concrete Mixing Plants

2024-08-08

Generally speaking, the aggregate conveying of concrete mixing stations often adopts belt conveyors or bucket lifting. These two methods have their own characteristics. This article explains the difference between the two in detail. I. Bucket-lifting 1. Working principle The bucket-lifting uses a brake winch and is pulled through a pulley block and a wire rope to achieve the purpose of lifting the bucket. In large and medium-sized mixing stations, double wire rope transmission is often adopted; in small mixing stations, most of them directly adopt a suspended single rope transmission or a single rope transmission guided by a pulley installed on the bucket. 2. Features The advantages of bucket lifting are small footprint and simple structure, which are suitable for narrow construction sites. Schematic diagram of bucket-lifting and inclined belt conveyor: II. Inclined belt type 1. Working principle The belts are connected into a closed loop, and they are tightened with a tensioning device. Driven by the motor, the friction between the conveyor belt and the drive roller makes the conveyor belt run continuously, thereby achieving the purpose of transporting...

How to Deal with the Electrical Control System Failure of Concrete Mixing Station

2024-08-07

In the long-term daily production and operation of concrete mixing station, it is inevitable that there will be failures in mechanical equipment and control system. Today, the auxiliary mechanical mixing station mainly tells you about the possible faults of the electrical control system of the mixing station and the countermeasures! 1. PLC cannot communicate Due to poor contact of communication line or communication network connector, or damage of communication and expansion module, the PLC electronic system fails. Therefore, the communication line, communication connector and communication expansion module can be inspected and replaced. 2. The digital display meter is garbled or the power supply is out of phase When the digital display meter is garbled, it can be checked step by step and then replaced; The lack of phase of external power supply is due to the burnt contact of contactor or circuit breaker, the current of circuit breaker is not set properly or the burnt contact of contactor causes the lack of phase; Elimination method: the power supply can be checked and updated. If the circuit breaker is found to...

Common Failures of Concrete Mixing Station-Reversing Valve Failure & Component Failure

2024-08-06

1. Reversing valve failure The faults of the reversing valve include: the valve can not be reversed or the reversing action is slow, the gas leaks, and the electromagnetic pilot valve is faulty. (1) The reversing valve can't reverse or the reversing action is slow, which is generally caused by poor lubrication, the spring being stuck or damaged, oil pollution or impurities stuck in the sliding part, etc. In this regard, we should first check whether the oil mist device works normally; Whether the viscosity of lubricating oil is appropriate. If necessary, replace the lubricating oil, clean the sliding part of the reversing valve, or replace the spring and reversing valve. (2) After long-term use, the reversing valve is prone to wear of the sealing ring of the valve core and damage of the valve stem and valve seat, resulting in gas leakage in the valve, slow action of the valve or abnormal reversing. At this time, the sealing ring, valve stem and valve seat should be replaced, or the reversing valve should be replaced. (3) If the inlet and...
