You decide whether to operate the mill in open or closed circuit, with or without a pre-grinder and with side or central drive, according to your plant layout and end product specifications. Even the lining types are tailored to your operating parameters.

In addition, the large through-flow areas enable the mill to operate with large volumes of venting air and a low pressure drop across the mill. This reduces the energy consumption of the mill ventilation fan and keeps your energy costs down.

The mill is based on standard modules and can be adapted to your plant layout, end product specifications and drive type. The horizontal slide shoe bearing design enables much simpler foundations and reduced installation height, making installation quicker and less expensive.

Our shell linings are designed to suit the task at hand. In our two-compartment cement mills, the first compartment (for coarse grinding) has a step lining suitable for large grinding media. It protects the shell while ensuring optimum lifting of the mill charge. In the second compartment (and also in our one-compartment cement mills) we use a corrugated lining designed to obtain the maximum power absorption and grinding efficiency. For special applications, we can supply a classifying shell lining for fine grinding in the mill.

In fact, the entire mill is protected with bolted on lining plates designed for the specific wear faced by each part of the mill. This attention to detail ensures both minimal wear and easy maintenance. When a wear part has reached the end of its life, it is easily replaced.

The grinding media are supplied in various sizes to ensure optimum grinding efficiency. The STANEX diaphragm is designed to maximise the effective grinding area, enabling a higher throughput. It is fitted with adjustable lifters to ensure the material levels in each compartment are right. Best of all, the STANEX diaphragm works for all applications, even when material flow rates are high and the mill feed is moist.

The mills are typically driven by our FLSmidth MAAG LGDX side drive - gearing rated to the latest proven AGMA standards. The mill drive is provided with an auxiliary drive for slow turning of the mill. The LGDX includes two independent lubrication systems, one which services the girth gear guard and intakes more dust, and a second which supplies oil for the fast-rotating gearing and bearings and stays clean. If requested, however, the mills can be provided with a central drive: the FLSmidth MAAG CPU planetary gearbox. The mill design differs slightly, depending on whether the side or central drive is chosen.

Each grinding compartment has two man-hole covers to give easy access for maintenance. As there are minimal moving parts, the maintenance requirement is low and simple changes like replacing wear linings and topping up grinding media can be completed quickly and easily. Horizontal slide shoe bearings prevent oil spillages from the casing and offers easy replacement of slide shoes.

Buying a new mill is a huge investment. With over a century of ball mill experience and more than 4000 installations worldwide, rest assured we have the expertise to deliver the right solution for your project. Our ball mill is based on standard modules and the highly flexible design can be adapted to your requirements. The mill comprises the following parts.

The mill body consists of an all-welded mill shell and a T-sectional welded-up slide ring at either end, the cylindrical part of which is welded onto the ends of the shell. The mill shell has four manholes, two for each grinding compartment.

Each slide ring runs in a bearing with two self-aligning and hydrodynamically lubricated slide shoes. One of the slide shoes at the drive end holds the mill in axial direction. In the others, the slide rings can move freely in axial direction to allow for longitudinal thermal expansion and contraction of the mill body.

The slide shoes are water-cooled, and each bearing is provided with a panel-enclosed lubrication unit including oil tank, motorised low- and high-pressure oil pumps, as well as an oil conditioning circuit with motorised pump for heating/cooling and filtration of the oil.

The stationary steel plate inlet duct leads the venting air into the mill. It is equipped with a manually operated throttle valve and a pressure monitor to adjust the pressure at the inlet end, thus preventing dust emission from the inlet. The feed chute is lined with bolted-on wear plates and slopes down through the air duct to the mill inlet opening.

The more control you have over the mill, the better your grinding efficiency is likely to be. Our ball mills include monitoring systems to continuously measure the material and air temperatures as well as the pressure at the mill exit. The venting of the mill is adjusted by a damper in the inlet to the mill fan. And the material fill level is continuously monitored by means of sensors. For ball mills operating in closed circuit, the circulation load is monitored by weighing the flow of reject material from the separator. These measures ensure you achieve optimum mill performance, giving you the quality, efficiency, safetyand reliability that you need.

With years of experience in the cement and mining industries and over 3000 mills sold worldwide, FLSmidth continues to develop its range of efficient milling and grinding solutions. This experience and know-how, as well as close collaboration with our customers, means we can deliver advanced milling and grinding technology solutions that puts us at the forefront as a partner.

We know that you strive to increase production while saving on CAPEX, operation and maintenance costs. Further, consideration for the environment is a priority for production industries, making energy-efficient designs highly sought after. So, these are our priorities when designing milling and grinding equipment to meet your needs.

Milling and grinding of raw material, minerals and cement is a rough process, with highly abrasive and hard feed materials that can accelerate equipment wear and tear. This leads to increased costs for equipment and spare parts replacement, and costly maintenance. It is crucial that the equipment used for milling and grinding can withstand such harsh materials. Our range of milling and grinding technologies have been tried and tested around the globe. Our vertical roller mills, horizontal mills, hydraulic roller presses and stirred mills have for many years offered efficient milling and grinding, flexibility, cost savings and easier maintenance. Whatever the application, one of our robust milling and grinding solutions will be suitable for grinding all types of feed materials including hard rock ores, raw, cement or slag. We work closely with you to realise the potential of the technology that will benefit you. Some of the features you can benefit from in our milling and grinding solutions include:

With the knowledge and experience gained throughout the years, we ensure that you have the best milling or grinding solution possible, whether you are working in the cement industry or mining industry.

For the cement industry, our Hydraulic Roller Press is suitable for water-scarce locations as it does not require water for deagglomeration of feed material in the roller press. It is also adaptable to three different types of grinding setups: pre-grinding, semi-finish grinding and finish grinding. The OKTM mill can skilfully grind raw or cement feed material and offers parts commonality, simplifying spare parts inventory and facilitating easy switching of parts between vertical roller mills. Our ATOX coal mill has large rollers with great grinding capability of all types of coal, tolerating moisture levels up to 20 percent.

For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

Our ball mills are the most robust design in the industry, available with either geared or gearless drive arrangements. The cost-effective FT Series mills are smaller, gear driven and feature hydrodynamic lubrication.

Understanding the challenges you face when milling and grinding hard feed material, we have built our technologies to last. We have paid particular attention to the wear parts because they are right there where the action is, making it all happen. We hardface them with the toughest

There is no doubt that milling and grinding cement and other feed material is tough work.

peri autocharge mill grinding ball charging system

peri autocharge mill grinding ball charging system

When charging a grinding mill, the standard practice is to dump tons of balls into the mill at once and replace them somewhere between once a shift and once a week. Its an inefficient practice that wastes energy, impacts product particle size distribution and risks breakage of mill linings and grinding media. Fortunately, we can offer you a better option with our Mill Grinding Ball Charging System.

Our PERI AutoCharge Mill Grinding Ball Charging System is designed to provide a controlled continuous supply of balls to maintain consistent ball loading in the grinding mill. Continuously charging grinding balls will allow your mill to maintain a consistent power draft, charge volume, ore feed rate, or consumption average (kg/t). Our system effectively mitigates the number of variables in the control formula of your mill to optimise the performance of your operation.

Worker safety is paramount for any business and our PERI AutoCharge Mill Grinding Ball Charging System will help protect your employers by minimising or eliminating the frequent movement of ball kibbles, drums or sacks by overhead crane. Youll also be able to further improve the safety of your plant by mounting our ball feeding device over a feed conveyor or bucket elevator fed by gravity from ball storage. That way, youll be able to completely avoid the inconvenience and safety issues related to placing overhead crane access and intra-plant transport over equipment and personnel.

Bulk charging will cause your mill to be either overcharged or undercharged with grinding balls, resulting in some combination of poor product sizing, reduced throughput. Our system will ensure your mill is always correctly charged by allowing the ball feed rate to be adjusted to account for changes in operating conditions. Additionally, our system provides you with alternative ball accounting choices to allow you to properly manage your grinding media.

Unlike bulk charging practices, our PERI AutoCharge Mill Grinding Ball Charging System will ensure your mill is always properly charged. That means your mill will be processing more while conserving energy. Youll also be able to better protect your staff and extend the life of your equipment.

The AutoCharge feeder continuously charges balls from the storage bin to the mill. The feed wheel picks up balls in each flight and when they pass the top-centre of the wheel, they roll off into either the counting chutes or the weighing module before dropping directly into the mill feed stream.

The AutoCharge system is primarily suitable for SAG mill balls (100150 mm). As each ball rolls through the counting chute, an electro-mechanical limit switch is activated, signalling the counter. Each count is added to the last, allowing a continual increasing total count of balls to enter the mill over a set time period. The total ball count can be monitored on the control panel at any time. A controller is used to set the ball addition rate, assign ball weight, reset the ball counter, and reset after clearing a ball jam or empty bin alert. Each ball feeder/counter system is designed to accept a narrow range of ball diameters and should not be used to charge balls of mixed sizes.

The AutoCharge systems weight-based counter is suitable for all ball diameters but is particularly applicable to smaller ball sizes (5080 mm), including ball recharge practice involving multiple sizes. As the balls exit the feed wheel, they are collected in an articulating scoop. The loaded scoop is weighed by an array of load cells; the weight is recorded and summed to the previous total; and balls are discharged into themill feed stream.
