What are the two batching methods of concrete mixer? After our technicians summed up the concrete mixer according to the batching control mode is divided into: belt type, cylinder type.

1、皮带配料式：其结构多为上部是原料储料斗，下部为计量斗，底部为卸料输送皮带，储料斗用于储存待配原料，储料斗底口下方正对配料输送皮带。

1. Belt proportioning type: its structure is mainly composed of raw material storage hopper at the upper part, metering hopper at the lower part, and unloading conveyor belt at the bottom. The storage hopper is used to store raw materials to be prepared, and the lower part of the bottom opening of the storage hopper is directly opposite to the batching conveying belt.

其原理：配料开始，皮带机启动带出储料斗中原料设定值时皮带停止，然后在控制仪表控制下，依次配置下几种物料，所有物料配置完毕，仪表控制启动卸料皮带将物料送入下一环节（如搅拌机提升斗或输送皮带机等）皮带配料式多用于中小型施工现场，因其物料基数较小，为进一步提高配料精度、减小误差值但又不影响配送效率，可采用低速配料、快速卸料方式。

Its principle: when the batching starts, the belt conveyor starts to take the raw materials out of the storage hopper to the set value, and then the belt stops. Under the control of the control instrument, the next several materials are configured in turn. After all the materials are configured, the instrument control starts the unloading belt to send the materials to the next link (such as mixer elevator or conveyor belt conveyor, etc.) belt batching is mostly used in small and medium-sized construction sites In order to further improve the batching accuracy and reduce the error value without affecting the distribution efficiency, the low-speed batching and fast unloading mode can be adopted.

使用此类配料机的用户为降低采购成本，多希望借用配料机的计量斗来同时计量散装水泥，通过水泥螺旋输送机将水泥仓中的水泥打入配料机计量斗，一般不主张此用法，因为水泥流动性好，会造成计量斗口与输送皮带间隙有少量水泥溢出，而造成现场粉尘污染或水泥损失，如非要使用此方式则必须采用槽型皮带托辊，且斗口边加设软薄挡边，方能控制水泥外溢。

In order to reduce the purchasing cost, users of this kind of batching machine hope to use the metering bucket of the batching machine to measure the bulk cement at the same time. The cement in the cement bin is pumped into the metering bucket of the batching machine through the cement screw conveyor. Generally, this method is not advocated because of the good cement fluidity, which will cause a small amount of cement overflow between the metering bucket mouth and the conveyor belt, resulting in dust pollution on site or If it is necessary to use this method, the trough belt roller must be used, and the soft and thin rib should be set at the edge of the bucket mouth to control the cement overflow.

2、气缸配料配料机：其结构多为上部是原料储料斗，为加大储料容量多设置加高板，下部为计量斗：各配料门下可配一整体计量斗，使各物料依次配入同一计量斗（累积计量），也可在每个配料门下设置单计量斗（各称各料），完成计量的物料由底部皮带输送机送入下一环节。气缸配料式利用的是物料重力自流下楼方式，因此配料速度快，适用于中大型搅拌站，目前HZS50以上混凝土搅拌站（楼）多采用。

2. Cylinder batching and batching machine: its structure is mostly composed of raw material storage hopper, in order to increase the storage capacity, a heightening plate is set, and the lower part is a metering bucket: an integral metering bucket can be equipped under each batching gate to make all materials in turn allocated into the same metering bucket (cumulative measurement), or a single metering bucket (each called each material) can be set under each batching door, and the metered materials are delivered by the bottom belt conveyor Move on to the next step. The cylinder batching type uses the material gravity flow down the stairs, so the batching speed is fast, which is suitable for medium and large mixing stations. At present, the concrete mixing plants (buildings) above HZS50 are mostly used.
