Vertical roller mill separator can be summarized as: "decentralized", "classification", “collection." Dispersion means materials that enter the separator should throw off as much as possible. There should be a certain spatial distance between the material particles. Therefore, sprinkle trays structure, speed, spreading the material space, material moisture and material flows speed has a direct impact on the fabric and dispersion effects.
1.The separator is energy saving, high output, high quality requirements, the closed-circuit grinding becomes an inevitable trend of cement grinding process.
2.The necessary equipment of closed-circuit grinding is the powder selecting machine.
3.The function of Powder selecting machine is to choose standard particles among the discharging material.
4.Powder selecting machine does not produce fine powder itself, but due to select the fine materials, it avoids the occurrence of the mill material cohesion, adhesion grinding body and stick position.
5.And it can reduce over-grinding materials. Thus it can timely and conveniently adjust cement production varieties, increase high fineness of cement, and improve the grinding efficiency

Grinding table is one of key parts of vertical roller mill. It includes drag rings, lining plate and base. The optimization and improvement are made basing on traditional grinding table casting technology, that the most advanced sodium silicate-bonded sand molding technology, to overcome deficiencies in structure and make the grinding base bear force equivalently. All these measures avoid material’s washout problem on no-wear-resisting surface
1. High hardness, anti-cracking, wear resistant, fine workmanship
2. Arc air gouging and shot blasting are used to casting steels’ finishing, to make sure good appearance quality.
3. NDE inspections are applied on stress surface before delivery, to ensure products are good in stress capability and stable in operation.

Grinding roller is core part of vertical mill. Great Wall Casting can provide customized service according to customers’ different processing requirements. Besides, it provides finished product manufacturing service for grinding roller including casting, finished machining, surfacing welding, etc. We gained good reputation from customers
1. Grinding rollers produced by Great Wall Casting have features of high hardness, good anti-cracking and strong wear-resistant capability.
2. During grinding roller production, technicians carry out finishing processing with arc air gouging, which can guarantee outlook quality of steel castings.
3. We promise that, all the grinding rollers shall be NDT inspected on the stress surface through routing testing methods to ensure that each grinding roller is qualified before leaving our factory. Any sub-standard product is forbidden to leave factory.
Introduce of cement vertical roller mill hub
Weight: 5~30T
Applicable devices: all types of vertical mills, mineral slag vertical mills, cement vertical mills, steel slag vertical mills, nickel slag mills, raw material vertical mills and coal vertical mills.
Application: Cement, building material, chemical, coal, electricity, metallurgy, non-metallic mine, etc
Customizable: Yes
Wheel hub is the core part of grinding roller assembly. The roller cover is fixed on the hub, and the hub is installed on roller shaft, which forms the grinding roller assembly. Generally speaking, roller shell and wheel hub is connected together in the tapered structure, which is convenient for easy maintenance and disassembly
1. The Wheel hub of grinding roller produced by Great Wall Casting has good wear-resistance, and are hard to break.
2. We always insist on this principle: before delivery, the professional inspectors carry out many times NDT tests on the stress surface of wheel hub. No product with bad quality can leave factory
Introduce of cement vertical roller mill rocker
Weight :10-25 t
MaterialASTM :1035 / DIN: CK35
Applicable devices: vertical mills, mineral slag vertical mills, cement vertical mills, steel slag vertical mills, nickel slag mills, raw material vertical mills and coal vertical mills.
Application: Cement, building material, chemical, coal, electricity, metallurgy and non-metallic mine
Customizable: Yes
Vertical mill rocker is one of key components of vertical grinding mill. It includes upper rocker, down rocker, rocker shaft, bearing, bearing seat, etc. The upper rocker is used to install the grinding roller, and the down rocker connects with hydraulic system. Two rockers are connected into a whole by shaft, taper sleeve and taper pin.
1.The vertical mill rocker produced by Great Wall Casting has better wear-resistant capability and good anti-cracking.
2.We carry out the dressing and finishing by arc air gouging and shot-blasting for the steel castings to guarantee the appearance quality.
3.Before delivery, all the rockers will have NDT inspection several times as per perfect inspection flow. Any defective product is forbidden to leave factory.
