The screening a Static Grizzly separator does is sort and classify the rock according to size. The first stage is SCALPING. This is the practice of removing any material that may slow production. It may be rock that is too big for the equipment to effectively handle, or fine material that is taking up valuable space and will consume precious energy if there is further handling. The name of the equipment that performs this function is called a GRIZZLY. The equipment is limited to a maximum size of rock that it can accept. The grizzly is a pattern of heavy steel bars that are laid down in a grid pattern. This grid will allow the small rocks to go through. The larger rock being bigger than the grid opening wont. This rock then can be either sent for further size reduction, or removed.

The purpose of this is to keep the grizzlies down time to a minimum by preventing the oversized rock from piling up while on its surface. The effectiveness of the sizing will be lowered due to rock that could go through sliding off. But as a counter balance the overall through put will be better due to the greater availability of the grid. If the Grizzlies performance rate is to low, then causing the grizzly to vibrate will increase the effectiveness of the sizing.

The Ross Chain Feeder illustrated in Fig. 3 is shown discharging the ore over a bar screen, or grizzly. It is advisable to provide a screen of this sort ahead of the primary breaker in order to bypass material that is already small enough to pass straight through the machine. The commonest device is a stationary grizzly from 6 to 12 ft. long, slightly wider than the stream of ore, and set at a slope of from 45 to 60 to the horizontal. The bars, which should be of mild steel, are preferably wedge-shaped with the wider part uppermost. They are held together by long bolts at right-angles to their length and are kept at the desired distance apart by spacing washers, which often consist of old piping cut to the required length. The clearance betweenthe bars at the upper end should be the same as the discharge opening of the crusher which the grizzly serves, but at the lower end it should be slightly greater to prevent choking.

A grizzly of this type, though cheap and simple, tends to get clogged with ore. In conjunction with a Ross Chain Feeder, however, clogging is eliminated and the length of the bars can be reduced by 50% or more.

Bars are a widely used means of reducing the work of primary or secondary crushers. As the ore is fed to the crusher, it passes over the grizzly bars, and the finer pieces drop through into the mill ore bin. The grizzly is made of wear resisting wedge shaped bars easily replaced if necessary.

Grizzly Bars are punched and held in place by steel rods passing through the holes. Cast iron spacers, of the proper shape and width, are placed between the bars. Various types of bars and spacers can be supplied, depending upon the application.

A vibrating grizzly screen has been developed as a distinct improvement over the fixed grizzly now in such wide use.It combines the functions of screening and feeding the ore to the primary crusher, and, by eliminating the undersize product in the ore feed to the crusher, materially increases the crusher capacity. In addition, due to the pulsating action of the unit, the ore is fed positively to the crusher, at a controlled rate and the manual labor usually required is eliminated.

The unit consists of a strong, frame mounted, standard grizzly which receives a positive eccentric motion in a lateral plane through connecting links attached to the head motion of the jaw crusher. Due to this positive action the angle of slope of the grizzly may be much less than that required in fixed type grizzlies; and head room or fall may be reduced.The Shaking Grizzly is constructed in several sizes to fit standard Jaw Crushers.

Aggregate production plants use screens to direct, separate, and control material flow in the process. The two main purposes for screening the aggregates are to remove oversize material from the crusher product or undersizematerial from the crushing plant and to completely size the materials produced. An aggregate production plant must perform both functions.

The feed may contain some material that does not have to be crushed and which should be removed from the input to the primary crusher. A scalping unit is frequently used between the feeder and the primary crusher to remove from the feed material that is smaller than the setting of the crusher. It may be a grid, grate, or screen, and it may be stationary or it may vbrate. Raw material removed from the feed is sent to finish screens and reduction crushers.

Vibrating Grizzly Feeders are engineered to combine the functions of feeding and scalping into one unit, reducing the cost of having two separate units. Vibrating Grizzly Feeders are mainly used in a primary applications feeding a primary crusher. The Vibrating Grizzly Feeder provides a continuous feed rate under a variety of loading and material conditions. Vibrating Grizzly Feeders are designed to take heavy shock loads from trucks, shovels and loaders. This type of feeder can be used in quarries, recycling, industrial processing, mining, and sand and gravel operations, as well as in a wide range of processing industries.

The McLanahan Vibrating Grizzly Feeder has a history of reliability and durability. McLanahan offers feeders in five different widths to match up to the crusher opening width. For example, McLanahan designs feeders with shallower sides for use in portable plants where over plant height is limited. We also design feeders with deeper sides for stationary applications where large haul trucks are dominantly used. Unlike many manufacturers of Vibrating Grizzly Feeders, McLanahan is enthusiastic to work with customers on applications that require special features not offered by our competitors.

The Vibrating Grizzly Feeder consists of a pan section at the feed end to receive and start segregating the material. The discharge end consists of a grizzly section with openings that allow the undersized material to pass before discharging into the crusher. The feeder is mounted on springs and vibrated via a mechanism located underneath the feeder pan, protecting it from misfed material that fails to reach the feed hopper. The vibration force is angled to the feeder, pointing toward the discharge end. This action of the vibrator forces the material toward the discharge end while segregating the material, causing the finer particles to move toward the bottom of the load.

As the material travels to the grizzly section, the finer material settles to the bottom and passes through the openings in the grizzly. This bypassed material decreases the amount of material going into the crusher, reducing the size of the crusher required as well as the wear inside the crusher. The bypassed material can be combined with the material going through the crusher on the under conveyor. This prescreened material protects the under conveyor from the impact of the material exiting the crusher. The prescreened material can be segregated as a product, or it can be discarded if the fines in the material are a contaminate.

The main purpose of a Vibrating Grizzly Feeder is to feed a primary crusher in a primary application. Vibrating Grizzly Feeders reduce the amount of material going into the crusher by scalping out the product size ahead of the crusher. This reduces the size of the primary crusher required.

Vibrating Grizzly Feeders can be used in rip-rap plant applications to sort ROM material for use on dams, water control and decorative stone applications; for sorting gravel in dredge applications for sized decorative landscaping applications; to scalp roots out of dirt and other materials to improve the product value for a customer; or to spread material from a conveyor to a wider secondary crusher, such as a Roll Crusher, where no grizzly section is required.

Feeders are an important part of any processing circuit. They meter and convey material at a controlled rate into a crusher, sizer, scalper, conveyor or other feeder. They must be correctly sized to achieve maximum throughput and optimum uptime. Download this guide for tips on how to size and select a Feeder for your application.

Sizing is the general separation of products according to their size. The simplest form of sizing is screening, the purpose of which is to separate minerals or other materials into specific particle sizes to create various final products.

When selecting equipment to screen a product, considerations should be given to material being screened, including shape and size; screen media openings; amount of material already to size; presence of harmful materials; need for water; and more. McLanahan offers a variety of screening solutions for both wet and dry applications to fit the needs of producers in many industries. Learn more about McLanahans screening solutions on the individual product pages.

McLanahan Vibratory Screens separate material through the vibration of screen decks covered in screen media of various sized openings. As the screen decks vibrate, the smaller material falls through the openings, while the larger material remains on the top of the screen deck.

McLanahan offers Feeders that provide screening/sizing capabilities in addition to controlling the flow of material to various pieces of equipment. These feeders can scalp out fines and remove material that is already to size to minimize wear on the crusher.

Screening equipment plays a large and important role in a processing plant. It can greatly affect your plants capacity, as well as the quality of your products. Screening equipment can be stationary or portable, designed for quick setup and teardown and for easy transport from site to site.

Screening equipment is commonly used to size and separate material throughout the production process. Screens used ahead of a primary crusher can remove fine material, like abrasive stone or sand, which can cause wear and tear on the crushers liners. They can also keep material that is already to size from entering the crusher feed, which reduces unnecessary power consumption and wear on the machine.

After the primary crushing stage, screens with multiple decks can separate material into various categories for further crushing in the secondary and tertiary stages. They can also decrease the load the crushers and other processing equipment have to handle by removing undersized and oversized material from the feed ahead of the next reduction stage.

Screens can also be used in other stages of the processing plant to produce a final, saleable product, as well as to dewater washed material to less than 14 percent moisture for easy conveying and/or stockpiling.

To size and separate material, screening equipment employs a vibrating or tumbling action that causes the feed material to divide by size. The screen media removable, easily replaceable panels attached to the deck frame through which undersized particles pass makes the separation by allowing smaller particles to pass through its openings. Larger particles rise to the top of the material bed due to the vibrating or tumbling action of the screen, while smaller particles filter out through the openings in the screen media, creating two or more fractions.

Each application is unique in its screening needs, though every application relies on its screen media for successful material separation. Popular screening media includes woven wire cloth, urethane, rubber or a combination of urethane and wire cloth or urethane and rubber. Each type of screen media offers producers different options when it comes to capacity and efficiency, and efficiency is key to creating a quick return on investment.

Besides sizing and separating material, screening equipment can also spilt a feed stream for separate processing, remove refuse material, reduce fines generation, and minimize crusher size. Screening equipment that is used effectively can make your processing plant more efficient.
