什么是螺旋分级机?

中信重工是中国领先的螺旋分级机工厂和供应商,专业制造高性能选矿设备。
我们的螺旋分级机(又称螺旋洗砂机)广泛应用于矿山、洗砂和选矿厂。与球磨机配合使用时,可形成高效的闭路磨矿系统,将粗颗粒物料返回磨机,同时排出合格的细粒溢流。
其利用固体颗粒在液体中比重和沉降速度不同的原理,按粒度对物料进行分级。具有结构简单、运行可靠、处理量大、分级区稳定、分级效率高等特点。

螺旋分级机的优势及选择我们的理由

我们提供全系列重型工业螺旋分级机,满足多样化的物料筛分需求:

1. 高堰式螺旋分级机:
最适合粗颗粒分级,通常溢流粒度为0.4mm至0.15mm。

2. 沉没式螺旋分级机:
专为细颗粒分离设计,溢流粒度一般低于0.2mm。

3. 单螺旋和双螺旋分级机:
提供单轴或双轴配置,匹配您的特定处理能力(可选脱水螺旋分级机用于洗砂)。

4. 极低的维护成本:
相比水力旋流器,螺旋分级机维护成本降低约35%,结构更简单,更适合偏远矿区。

5. 卓越的回收率:
物料精准分级,整体回收率高达90%,显著提升整条生产线的产量。

6. 高度适应性:
无论给料量或浓度波动,均能保持稳定产量,是闭路磨矿系统的首选。


技术亮点

1. 分级效率高:
优化的螺旋叶片螺距和角度设计,最大化重力沉降和提升效率。

2.卓越耐磨性能:
螺旋叶片内衬高锰钢、耐磨合金或橡胶板,在磨蚀性矿山工况下延长使用寿命。

3.重型结构设计:
坚固的料槽结构及强力自提升装置,确保重载工况下平稳连续运行。

螺旋分级机的工作原理是什么?

螺旋分级机的工作原理基于固体颗粒在液体介质中因粒径和比重差异而产生的沉降速度不同。

1. 矿浆给入:
混合矿浆(矿浆)被送入位于倾斜槽中部的沉降池。

2. 重力沉降:
在重力作用下,较大且较重的颗粒迅速沉至槽底,形成“粗砂”(底流);较轻且较细的颗粒悬浮在水层上部,形成“细粒”(溢流)。

3. 螺旋提升与脱水:
连续旋转的螺旋叶片将沉降的粗颗粒从底部刮起,并沿倾斜槽向上输送。在向上输送过程中,水分回流至池中,起到脱水螺旋分级机的作用。干燥的粗颗粒最终从上端排砂口排出,通常返回球磨机进行再磨。

4. 溢流堰溢流:
悬浮的细颗粒从槽体下端经溢流堰流出,进入下一阶段处理,如浮选或重选。

常见问题

本部分旨在解答客户关于设备日常操作、维护、产品优势及售后服务等最迫切的问题,帮助您全面了解我们的综合实力,为项目做出明智决策。

其工作原理基于沉降速度。在液体介质中,不同粒度和比重的固体颗粒沉降速度不同。粗重颗粒沉降至倾斜槽底,由旋转螺旋向上推送至排料口进行再磨,而轻细颗粒则悬浮并随溢流堰流出。

高堰式分级机适用于粗粒分级(大于0.15mm),而沉没式分级机的螺旋部分完全浸没在矿浆中,适用于细粒分级(小于0.15mm)。

螺旋分级机价格主要取决于螺旋直径、螺旋数量(单螺旋或双螺旋)、溢流堰类型(高堰或沉没式)以及具体衬板材料。请联系中信工程团队获取详细的定制技术方案和工厂直供报价。

可以,通常通过重力溜槽与球磨机连接形成闭路系统,自动将不合格的粗粒物料送回再磨。

主要区别在于溢流堰相对于螺旋轴的高度: 高堰式:溢流堰高于螺旋轴下端轴承,但低于溢流端螺旋叶片上缘。适用于分离粗颗粒,通常用于分级粒度大于0.15mm的物料。 沉没式:溢流端螺旋完全浸没在液面以下。提供更大、更稳定的沉降区域,非常适合细颗粒分级,通常用于粒度小于0.15mm(尤其是0.074mm以下)的物料。

调整螺旋分级机的分离粒度可通过控制以下关键操作参数实现: 矿浆浓度:降低给矿浓度可减小矿浆粘度,使颗粒沉降速度加快,从而获得更细的溢流产品。 给矿速度:保持稳定均匀的给矿可避免沉降池产生紊流,确保精确的颗粒分级。 溢流堰高度:提高溢流堰高度可增加沉降池容积和停留时间,从而获得更细的溢流。

为减少磨蚀性矿石造成的磨损,中信重工提供定制化耐磨保护方案: 高锰钢/合金衬板:适用于高冲击、高磨损的重型工况。 聚氨酯/橡胶衬板:强烈推荐用于非金属矿物或细粒矿浆的湿式分级,具有优异的耐腐蚀性和更长使用寿命。

为确保连续稳定运行,建议遵循以下维护清单: 润滑:定期对下部沉没轴承和上部减速箱加注润滑脂。下部轴承因在水下工作,必须保持密封。 提升装置检查:定期测试螺旋提升机构,确保带载停机时能平稳提升螺旋轴(防止螺旋被沉降物料掩埋卡死)。 磨损检查:监测螺旋衬板厚度,在磨损波及螺旋主体结构前及时更换。
