roller press

the hydraulic roller press offers cost-saving grinding | flsmidth

Due to its flexibility, reliability and energy efficiency, our Hydraulic Roller Press System, also known as the HRP system, is widely used in the cement industry. Hydraulic Roller Press comminution subjects the feed material to a very high pressure between its counter rotating rollers over a short time. The pressure exerted forms micro cracks in the feed particles, leading to the generation of a large amount of fine material.

The Hydraulic Roller Press has the capability to grind raw material, cement clinker or slag and is suitable even for dry feed materials and there is no need to add water to the roller press while processing.

The flexible Hydraulic Roller Press is suitable for both upgrades and new installations. Upgrading from a conventional grinding system can, in some cases, more than double your production capacity, while also reducing specific energy consumption by 30 percent. In ball mills, for example, less power is required to produce finished cement from Hydraulic Roller Press-pressed material than from un-pressed material.

In a pre-grinding setup, the Hydraulic Roller Press grinds the fresh feed and a specified amount of recirculated pressed flakes. This material mix then undergoes finish grinding in a conventional ball mill circuit. In comparison to a conventional ball mill system, this configuration provides an increase in production of approximately 25 per cent and a reduction in specific power consumption of approximately 10 per cent.

Where semi-finish grinding is desired, the Hydraulic Roller Press can be combined with a two-stage separator system and a conventional ball mill. A dynamic separator, which maintains the desired quality of the final product is paired with a static separator that ensures effective deagglomeration and aids in drying the feed material.

Upgrading a conventional ball mill with the Hydraulic Roller Press for semi-finish setups can increase production by up to 100 per cent or more, while also reducing specific power consumption by approximately 30 per cent.

If the Hydraulic Roller Press is used for finish grinding in a closed circuit with the two-stage separator system, the need for other grinding equipment is eliminated. The reliable Hydraulic Roller Press outperforms ball mills and vertical mills when it comes to finish grinding.

While the Hydraulic Roller Press can be used to upgrade ball mill systems for energy efficiency and enhanced production benefits, it is also exemplary in upgrading your vertical roller mill. The resulting benefits include increased production, without any increase in specific energy consumption, and increased availability of the overall grinding system.

Our unique roller wear surface TRIBOMAX is the strongest and most durable surface available, and is applied to the Hydraulic Roller Press rollers using a special state-of-the-art welding technology. TRIBOMAX has a 25,000-hour minimum guaranteed lifetime for Clinker grinding applications and can be designed to guarantee up to 40,000 hours of lifetime in select cases. We also provide conventional wear surface for applications in which your feed materials dont have high abrasiveness.

The two-stage separator system uses different separators for raw material grinding and clinker grinding applications. Put simply, the system is made up of a dynamic separator and a static separator. The dynamic separator exhibits low velocity through its rotor cage while the compact static separator establishes optimum velocity in the coarse separation zone. Our separator system is well known globally for its top-of-class efficiency.

Spherical roller bearings help to accommodate angular misalignments during operation. A sophisticated oil lubrication system provides bearing lubrication, cooling and filtering of lubrication media. Further, bearings mounted on the withdrawal sleeve allow easy and safe removal for maintenance.

The highly-sensitive metal detector recognises any metal-based foreign materials in the feed material, allowing identification and removal to ensure enhanced protection of the Hydraulic Roller Press. The metal detector also gives more flexibility when adjusting the zero gap between the rollers.

cement roller press - roller press in cement plant | roller press cement mill

The cement roller press is a kind of grinding equipment applied for brittle materials, such as cement clinker, granular blast furnace slag, cement raw materials (limestone, sandstone, shale, etc.), gypsum, coal, quartz sand, iron ore, etc. It is designed according to the principle of bed grinding, the high-pressure load directly acts on the material layer through double rollers, which causes internal stress in particles and leads to cracks to achieve the purpose of grinding.

The cement roller press has a high energy utilization rate and remarkable energy-saving effect in the material grinding process. In cement plant, cement roller press is a kind of important cement equipment used for clinker grinding. It is usually combined with a cement ball mill to form a high-efficiency cement grinding system because the practice shows that the grinding process with small grinding ratio and step-by-step completion is more energy-saving than that with large one-time completion.

Cement ball mill is a main cement grinding mill with a low energy utilization rate (only 3%-5%). Compared with the grinding energy consumption, most of its energy is consumed by collision heating and noise. Therefore, we usually adopt the cement roller press to replace the fine crushing and coarse grinding role of the ball mill. This increases the output of the ball mill system by 30-50%, and 20-35% of the extruded materials are smaller than 0.08mm, 65-85% are smaller than 2mm. Besides, a large number of cracks will be produced on all extruded materials, which will greatly reduce the energy consumption of materials in the next grinding process.

Pre-grinding system: after the material is pulverized by the roller press, all or part of them with a good extrusion effect will enter the subsequent ball mill for further grinding. This system has the advantages of simple processes, less equipment, wide particle size distribution, and stable cement performance. But because the ground material is not classified, a large number of fine powders are back to the roller press, the power saving range is limited.

Combined grinding system: materials ground by cement roller press are divided into two parts by air classifier: coarse part and fine part. The fine part will enter the ball mill to be further ground into the finished product, the coarse part will return to the roller press to be ground again. Because the cement finished products are all ground by the ball mill, the finished products have wide particle size distribution and the cement performance is stable.

Semi-finishing grinding system: after ground by cement roller press, materials are divided into three parts through an air classifier: coarse, medium and fine, in which the coarse material is returned to roller press for re-grinding, the medium material is put into ball mill for further grinding, and the fine material is directly discharged as the finished cement product. Because the roller press and the ball mill are two completely independent circulation systems, they are easier to operate and control and are more energy saving.

Finish grinding system: this system only includes a cement roller press to complete the grinding of cement clinker. Materials ground by cement roller press are divided into two parts by air classifier: coarse part and fine part. The coarse part will return to the roller press to be ground again and the fine part will be discharged as the cement product.

The cement roller press is composed of two rollers that rotate synchronously in the opposite direction and a set of a hydraulic system. Its main structure includes a press roller system, transmission device, mainframe, hydraulic system, feeding device, and so on.

The two rollers of cement roller press, one is fixed and the other is movable, which are driven by a motor and a reducer to rotate at a relatively low speed. The movable roller bearing seat is connected with the hydraulic system. It can be moved along a horizontal direction to control the gap between the two rollers, while the fixed roller is installed in the inner chamber of the mainframe. When materials enter between the two rollers from above, pressure (50-300Mpa) is transferred to materials by the hydraulic system through oil cylinder, bearing seat, and rollers so that material particle size can be reduced by means of extrusion. After grinding, the fine particles less than 90m account for about 20-30%. At the same time, there are many cracks in the coarse particles. In the process of further grinding, their energy consumption can be greatly reduced.

With our Roller Presses, the grinding pressure is transferred from the hydraulic system via the movable roll to the material bed and absorbed in a stable, closed machine frame. A key feature is the mounting of the rollers in oillubricated cylindrical roller bearings. The oil is both, lubricant and cooling agent. Alternatively, grease lubrication is possible. Power transmission from the electric motors is effected via cardan shaft, fluid or safe set coupling and clamping disc fitted gear boxes, usually of planetary design. Depending on the application, the rollers are either one piece solid construction or shaft and tire design with suitable wear protection for almost all applications in the cement and minerals industry.

The KHD Humboldt Wedag Roller Press is available in eight standard sizes ranging in grinding force from 2 to 20 meganewtons. KHD Roller Presses offer a reliable solution for every application for grinding cement, slag, raw material or for special applications, such as preparation of ore.

The drive power is transferred to the grinding rollers via multi-stage planetary gearboxes with first stage spur gears. The gearboxes are mounted on the drive end of the roller shaft using a hydraulic shrink coupling.. A V-belt drive can be used for drives of up to approx. 400kW per motor. Drives above 400kW are equipped with fluid or safe set coupling and cardan shaft.

The machine frame has identical upper and lower tiebars. Rubber pads are placed between the roller bearing blocks and the frame ends. The rubber pads act as an articulated joint and have a vibration damping effect. The RPS-type as a special type reduces maintenance time during roller changes. The doors in the roll cover permit rapid and wide access to the rollers for inspection and maintenance.

In KHD Roller Presses, the rollers are supported in radial, multi-row cylindrical roller bearings. This ensures an even load distribution on the roller bearing, substantially increasing the life of the bearing.

Oil lubricated roller bearings are standard with all KHD Humboldt Wedag Roller Presses. All contact points on the cylindrical roller bearing are supplied evenly with lubrication. Operating cost can be further reduced by checking the state of lubricant regularly (alternative grease lubrication).

KHD Humboldt Wedag Roller Presses offer rollers with appropriate wear protection for almost all applications in the cement and minerals industry. The two-part roller consisting of shaft and tire allows for economical surface replacement, single part rollers are used for high temperature grinding:

manual roller press 500 - formech us

The roller press is used for precise trimming of thin gauge vacuum formings e.g. clear blisters. The vacuum formings are located into a cutting die which is made to size. A cutting board is then placed on top and then the die is moved through the machine between the rollers applying a cutting force.

The finished part is cleanly cut from the surrounding waste material, leaving a flange which can be used for sealing to a backing card if required. The distance between the rollers is adjustable using a crank handle to give you a range of 5mm 125mm.

The main benefit of this process is a clean and accurate cut in thin materials usually under 1mm in thickness. This useful addition to the ancillary range is ideal for use with the Formech manual vacuum formers. The manual roller press requires no power supply. It is a very safe and easy machine to use and maintain.

cement roller press, roller press in cement plant | agico cement

The cement roller press is a kind of cement equipment for brittle materials, apply for cement clinker, and cement raw material, gypsum, coal, quartz sand, iron ore, blast furnace slag, and other materials.

The cement roller press is generally applied to the cement grinding plant, according to the real working process, cement roller press works with cement ball mill or vertical cement mill, which helps cement grinding plant to works well.

As new-type and energy-efficient cement grinding machine, cement roller press has advantages of energy-saving, high efficiency, less steel consumption and less noise. Both apply for new cement plant building and old cement plant revamping. According to the data, roller press helps ball mill system to increase the output by 30-50%. The 0.08mm fine material in the extruded material cake accounts for 20-35%, and smaller than 2mm accounts for 65-85%.

install the roller press in the cement grinding plant, the high pressure load is transmitted to the layer of the grinded material through the diameter of the double roller, most of the energy is used for the mutual extrusion between the materials. The sound energy and thermal energy generated by the friction of the material are transformed into the deformation energy of the material, which causes deformation, tearing and pulverization and fully utilize the potential of the cement grinding equipment, increase the output by 50-100%, and reduce the total energy consumption by 20%-30%. Promote the production efficiency of the entire system.

The material after grinding is greatly reduced in both particle size and the Bond function index, thereby greatly improving the grinding condition of grinding machine, and the power consumption of the entire cement grinding system is significantly reduced. It can save25-50% energy compared to traditional grinding methods, and the annual electricity saving are considerable.

Compared with the tube mill, the roller press is simple in structure, small in size, light in weight, and takes up less space in the workshop. It can save civil construction investment and also facilitate the original investment. In addition, the operation and maintenance of the roller press is very simple.

The material is squeezed and smashed continuously in the roller cover, and the harmful dust is not easy to spread. At the same time, the noise of the roller press is much smaller than that of the tube mill because of no impact.

The traditional tube mill is limited by processing, transportation, heat treatment and other conditions, and the large-scale tube mill is greatly restricted. The roller press grinding system solves such problems well.

The roller press works according to the principle of high-pressure layer pulverization, and adopts the work mode of single-grain pulverization. The brittle material is subjected to high pressure extrusion (the pressure of the machine in the pressure zone is about 150 MPa), the particle size of the material is rapidly reduced, the fine powder content of less than 0.08 mm reaches 20-30%, and the material of less than 2 mm reaches 70% or more, and a large number of cracks are present in all extruded materials, so that the energy required for the material to be ground in the next process is greatly reduced.

The main body of the roller press is two rollers that rotate in opposite directions, one is a fixed roller and the other is a movable roller. The brittle material is fed into the weighing chamber with the load cell by the conveying device, and then passes through the feeding device of the roller press into two rolls of the same size and opposite to each other, and the material is pulled into the nip by one side of the roller. The material is pressed into a dense material cake with high pressure, and finally falls from the nip, and is discharged from the hopper by the conveying device. The cake is further dispersed or ground by the next process.

Both the cementball mill and the cement roller press have their own advantages and disadvantages, but in actual production, the cement roller press has the advantages that the ball mill does not have, mainly reflected in the following points.

Note: Due to the large force of the roller of the roller press, the roller press has some problems, such as the material and the wear of the roller surface, the bearing is easily damaged, and the gear of the reducer is prematurely broken. In addition, the process operation process is strict. For example, the feed material column is required to be dense and full, and a certain feed pressure is maintained. The feed amount control should be appropriate, and the grinding process system configuration should be appropriate, otherwise its superiority cannot be exerted.
