How to Run a Concrete Block Machine Plant in Rainy Season

Rainy season can turn a stable concrete block plant into a difficult production environment. Aggregate moisture changes quickly. Cement must be protected from humidity. Fresh blocks need controlled curing without being washed by rain. Yard movement becomes slower, and finished products may be stained or damaged if storage is poorly arranged. A well-planned block machine plant can still run steadily, but it needs a different operating discipline.
雨季会使原本稳定的混凝土砌块厂变成一个生产环境恶劣的场所。骨料的含水量变化迅速，水泥必须防潮，新砌块需要控制养护，避免被雨水冲刷。厂区物料流动速度减慢，如果储存不当，成品可能会被污染或损坏。精心规划的砌块厂仍然可以稳定运行，但需要不同的操作规范。

This article explains how to keep a brick machine plant productive during wet weather, without relying on guesswork or excessive manual correction.

Rainy season risks for block production
雨季对区块生产的风险

The biggest rainy season problem is not only water on the ground. It is uncontrolled water entering the process. Wet sand changes batch weight and effective water content. Wet aggregate may bridge inside bins. Cement can absorb moisture if storage and conveying are not sealed well. If these issues are not controlled, the brick making machine receives a mix that behaves differently from batch to batch.
雨季最大的问题不仅在于地面的积水，还在于不受控制的水渗入生产过程。湿砂会改变混凝土的重量和有效含水量。湿骨料可能会在料仓内形成桥接。如果储存和输送密封不严，水泥也会吸收水分。如果这些问题得不到控制， 制砖机接收到的混凝土混合物就会出现批次间性能差异。

The symptoms are easy to see: sticky demoulding, soft green blocks, rough faces, height variation, chipped corners, slow curing, and more rejected pavers. In many plants, operators respond by changing water quickly. That may save one batch, but it can also make the next batch worse. The better solution is to control material exposure, dosing, transfer, and curing flow.
这些症状很容易观察到：脱模粘滞、砖块质地柔软呈绿色、表面粗糙、高度不均、边角破损、养护缓慢以及废砖数量增多。许多工厂的操作人员会通过快速换水来应对这些问题。这样做或许能挽救一批砖，但也可能导致下一批砖的质量进一步下降。更好的解决方案是控制材料的暴露、用量、输送和养护液的流动。

Raw material protection  原材料保护

Aggregate should be stored on a clean, drained surface. If possible, keep fine aggregate under a roof or cover it before heavy rain. Separate wet and dry zones. Do not feed the batching machine from random areas of the pile, because moisture can vary greatly from the surface to the bottom.
骨料应存放在清洁、排水良好的地面上。如果条件允许，细骨料应存放在有顶棚的地方，或在大雨前进行遮盖。应将干湿区域分开。切勿随意从料堆中取料到搅拌机 ，因为料堆的湿度可能从表面到底部差异很大。

Cement needs stricter protection. A sealed cement silo, clean screw conveyor, and dry receiving point help prevent moisture-related flow problems. If cement becomes lumpy, the mix becomes inconsistent and strength can suffer. Operators should check silo seals, air vents, and discharge behavior before rainy season begins.
水泥需要更严格的保护。密封的水泥筒仓、清洁的螺旋输送机和干燥的接收点有助于防止因水分引起的流动问题。如果水泥结块，混合料的均匀性就会下降，强度也会降低。操作人员应在雨季来临前检查筒仓密封、通风口和卸料情况。

Water dosing should be reduced only after considering the moisture already carried by aggregate. The goal is not to make the mix look dry. The goal is to keep the same forming behavior that the block making machine uses during normal weather.
只有在考虑了骨料本身所含的水分之后，才能减少加水量。目标不是使混合料看起来干燥，而是保持砌块成型机在正常天气条件下所表现出的相同成型性能。

Mixing and forming adjustments
混合和成型调整

During rainy season, mixing time and water addition sequence deserve extra attention. A concrete mixer must distribute moisture evenly, especially when aggregate enters with variable wetness. Some factories benefit from checking the first batch more carefully and setting a standard adjustment range for operators.
雨季期间，搅拌时间和加水顺序需要格外注意。 混凝土搅拌机必须均匀地分配水分，尤其是在骨料含水量不一的情况下。一些工厂通过更仔细地检查第一批混凝土，并为操作人员设定标准调整范围，从而获益。

A planetary concrete mixer can support uniform blending for pavers and face mix products, while a twin-shaft concrete mixer is suitable for strong mixing and efficient discharge. The important point is not only the mixer type, but whether the mixer, batching system, and block machine cycle are matched.
行星式混凝土搅拌机能够实现路面砖和面层混凝土产品的均匀混合，而双卧轴混凝土搅拌机则适用于强力搅拌和高效卸料。关键不仅在于搅拌机的类型，还在于搅拌机、配料系统和砌块机循环是否匹配。

In the forming section, do not change vibration pressure before confirming the mix. Hawen Machinery uses a four-shaft vibration box with external eccentric blocks. This design reduces resistance during vibration and helps compact the concrete more uniformly. When the rainy season mix is controlled, the system can maintain stable density and reduce cement waste caused by repeated trial adjustments.
在成型段，确认混凝土配比前切勿改变振动压力。哈文机械采用带有外部偏心块的四轴振动箱。这种设计可降低振动阻力，有助于混凝土更均匀地密实。在雨季控制混凝土配比时，该系统能够保持稳定的密度，并减少因反复试调而造成的水泥浪费。

Curing and yard management
养护和场地管理

Rain is not a substitute for curing control. Fresh blocks need moisture retention, but direct rain can damage surfaces, wash fines, stain products, and create uneven curing. Curing areas should protect products from direct rain impact while allowing controlled humidity and air movement.
雨水不能替代养护控制。新砌的砖块需要保持水分，但雨水直射会损坏表面、冲刷细粉、污染产品，并造成养护不均匀。养护区域应保护产品免受雨水直射，同时保持湿度和空气流通。

Yard drainage is equally important. If pallets sit in standing water, the lower products may stain or absorb moisture unevenly. A stable GMT pallet helps support fresh blocks, but it still needs a flat and clean route. Forklifts should avoid muddy ground, sudden braking, and rough turning, especially when products have not reached sufficient handling strength.
场地排水同样重要。如果托盘长时间浸泡在积水中，下方的货物可能会被染色或吸水不均。稳定的 GMT 托盘有助于支撑新装的砖块，但仍然需要平坦清洁的运输路径。叉车应避免在泥泞地面上行驶、急刹车和急转弯，尤其是在货物尚未达到足够的搬运强度时。

Molds must also stay clean. A hollow block mould or concrete block mould with wet buildup can cause sticking and poor edge release. Rainy season maintenance should include more frequent cleaning around mold cavities, feeding boxes, belts, and pallet contact surfaces.
模具也必须保持清洁。 空心砖模或混凝土砖模如果积聚了水分，会导致粘模和边缘脱模困难。雨季维护应包括更频繁地清洁模腔周围、进料箱、传送带和托盘接触面。

Equipment layout and safety
设备布局和安全

Rainy season exposes weak plant layout. Open belts, wet electrical cabinets, poor drainage, and unprotected material transfer points all create production risk. The plant should keep electrical control areas dry and easy to inspect. Cable routes, sensor positions, and operator platforms should be checked before heavy rain begins.
雨季会暴露工厂布局的薄弱环节。敞开式传送带、潮湿的电气柜、排水不畅以及无防护的物料输送点都会造成生产风险。工厂应保持电气控制区域干燥且易于检查。电缆布线、传感器位置和操作平台都应在暴雨来临前进行检查。

An automatic pallet provider can reduce manual pallet movement in slippery conditions. An offline palletizing system can also reduce random handling and help keep finished product stacking more consistent when yard movement is slower.
自动托盘堆垛系统可以减少在湿滑地面上的人工托盘搬运。 离线托盘堆垛系统还可以减少随意搬运，并在堆场移动速度较慢时帮助保持成品堆垛的一致性。
