机制砂立磨是专门用于生产机制砂的立式辊磨机，由于其结构和工艺特点具有中碎、细碎和粉磨功能；可用于
生产微粉、超细砂和细砂等产品，并具有烘干功能；
The manufactured sand vertical mill is the vertical roller mill specially used for the production of machine-made sand. Due to its structure and process characteristics, it has the functions of medium crushing, fine crushing and grinding; it can be used to produce micro powder, ultra-fine sand and fine sand, etc. material can be dried simultaneously;
立磨制砂系统可实现如下几种工况：
The VRM for manufactured sand system can realize the following working conditions:
● 单独生产微粉（≤ 0.08mm，如石灰石、火山灰、凝灰岩等微粉）；
Separately produce micro powder ( ≤ 0.08mm, such as limestone, volcanic ash, tuff and other micro
powder);
● 同时生产微粉和超细砂（0.08-1.18mm，细度模数 0.7-1.5），超细粉用作混凝土掺合料，超细砂用作特种砂
浆或瓷砖胶等产品的骨料；
Simultaneously produce micro-powder and ultra-fine sand (0.08-1.18mm, fineness modulus 0.7-1.5), ultra
fine powder is used as concrete admixture, the ultra-fine sand is used as aggregate of special mortar or tile
adhesive;
●
同时生产微粉、细砂（0.08-1.18mm）和中砂（1.18-2.36mm），超细粉用作混凝土掺合料，中细砂用作砂浆骨料；
Simultaneously produce fine powder, fine sand (0.08-1.18mm) and medium sand (1.18-2.36mm), ultra-fine
powder is used as concrete admixture, and medium fine sand is used as mortar aggregate;
●生产微粉和普通机制砂（0.08-4.75mm，细度模数 2.3—3.7），超细粉用作混凝土掺合料，机制砂用作混凝
土和砂浆骨料。
Produce fine powder and ordinary manufactured sand (0.08-4.75mm, fineness modulus 2.3-3.7), ultra-fine
powder is used as concrete admixture, and manufactured sand is used as concrete and mortar aggregate.
