A Brief Discussion on Key Technologies for Dust Control in Concrete Mixing Plants

With China's continuous urbanization, ready-mix concrete has been rapidly developed and applied in large and medium-sized cities across the country, leading to the rapid development of concrete mixing plants (buildings). Currently, there are numerous concrete mixing plant manufacturers in China, with a series of products. However, the technical level varies, with only some products approaching international advanced levels, and some technologies even surpassing imported concrete mixing plants.

Discussion on the reasons for concrete shortage

How to properly handle the problem of concrete shortage? Let's look at the professional answers given by industry experts, as follows: Ready-mixed concrete, as a product, has two characteristics when delivered: First, it is weighed and delivered by volume; second, it is signed for by ticket and settled by drawings. In the current buyer's market, the settlement shortage problem has always plagued ready-mixed concrete production enterprises.

Daily inspection of the mixing plant, fighting a tough battle for stable production throughout the year

Daily Inspection and Maintenance Details: a. Regular cleaning of the concrete mixing plant and its surrounding environment. b. Under normal conditions, sensors should return to zero, and ensure that no material accumulates in the hopper. c. The oil mist lubricator in the pneumatic system should maintain sufficient oil, and check whether the lubricating oil at each lubrication point is sufficient.

Experience in operating and managing a mixing plant

Before starting each batch, operators must check the following: the amount of lubricating oil in the mixer reducer gearbox, the amount of lubricating oil in the discharge gate hydraulic pump, the amount of lubricating oil in the mixer shaft head (should be more than 1/2), whether the amount of lubricating oil is sufficient, whether the pressure is normal, whether there are any breaks or detachments in the oil pipes and joints, and the lubrication points of the belt conveyor, screw conveyor, etc. Lubricating grease should be added as needed.

100 Questions about Ready-Mix Concrete (21-40)

What is the difference between a water reducer and a pumping agent? Answer: A water reducer is an admixture that reduces the amount of water used while maintaining the workability of the concrete mix, thereby increasing the strength of the concrete. A pumping agent, on the other hand, is mainly composed of a water reducer, with a small amount of plasticizer and slump-retaining components added to facilitate concrete pumping.

100 Questions about Ready-Mix Concrete (61-80)

Why are there three lines for each production mix ratio, and how should they be used? Answer: The first line is the theoretical mix ratio (i.e., the water content of sand and stone is zero), used by some plants. The second line is the production mix ratio used on dry days. The third line is the mix ratio used on rainy days and after rain.
