The batching machine is the main component of the mixing station, which can generally be divided into two methods: cumulative measurement and individual measurement. Cumulative metering generally adopts cylinder control to discharge materials. The cumulative metering of each material is more accurate than the earlier belt discharge metering. The required materials are mixed on the bottom flat belt conveyor after successive metering, and then conveyed to the inclined belt by the flat belt conveyor. Machine or lifting bucket. Separate measurement means that each material is measured separately through a separate weighing hopper. These processes can be carried out at the same time, saving measurement time and making the measurement progress more accurate. The volume and quantity of the storage hopper of the batching machine are designed according to the needs of users, generally 3-5 buckets and 8-40 squares/bucket, which can store different types of fine sand, sand and stones. The structure of the batching machine can be designed as a pure ground structure, a semi-ground warehouse structure or a full ground warehouse structure according to the needs of users. Due to the limited loading height of the loader, the pure ground structure requires the user to pre-cast the loading slope. The half-bottom silo structure or the full-bottom silo structure can save the loading slope, but the latter has a pit, so it needs to be done To improve the drainage of the pit, and to ensure the conveying capacity of the inclined belt conveyor, the inclined belt conveyor needs to be lengthened when the conveying angle remains unchanged, which increases the equipment cost.
