Sandvik jaw crushers

All Sandvik jaw crushers are of the single-toggle type with a deep, symmetrical crushing chamber and easy setting adjustment. Each model has a large feed opening for its size and an ideal nip angle, giving smooth material flow, high reduction efficiency and high capacity. Their simple design conceals many advanced features that give easy operation, simple maintenance, long life and a low cost per ton.

Every Sandvik jaw crusher is a product of know-how and experience optimized by Finite Element Analysis (FEA). Each model is tested virtually for stress, strain, shock, deformation, thermal loading, vibration and noise under a wide range of load conditions. The result is exceptional reliability.

The main difference between Sandvik jaw crusher and SBM jaw crusher is that Sandvik jaw crusher is a kind of mid-range mobile type, SBM's jaw crushers are heavy range type. Food size Sandvik jaw crusher is mobile and maximum 970mm. feed size of the fixed jaw crusher Sandvik is 1500 x 1300mm. The capacity of the Sandvik jaw crusher is between 50 and 1160 t / h.

SBM jaw is also divided in two by a normal chin and jaw JC series. JC series of these guys is more advanced than the standard chin. All these machines are stationay jaw crusher. SBM also moving jaw. However, several movable jaw Sandvik, which is just a device when SBM jaw jaw is set for mobile mining equipment, including the chin, vibrating feeder, vibrating screen and belt conveyor, etc. There are nine models of SBM jaw. Most of the power SBM jaw size is 1020 mm. The maximum number of SBM jaw is 400-1000T/h.

Industrial SBM jaw crusher is widely used to crush hard, medium hard and soft rocks and ores such as slags, construction materials, marble, etc., whose pressure resistance strength is under 200Mpa. SBM jaw crusher is mainly used to crush rock and mill machinery. Thank you very much balanced structure, the industry is one of the SBM jaw crusher machine easier and cheaper to install.

Along with the cast components of high quality special steel and durable wear parts, means exceptionally high crusher availability, cost-efficient crushing and low cost per ton. A total of SBM jaw is good performance, although the final particles and high crushing ratio. Compared with Sandvik jaw crusher, jaw SBM has a simple structure, easy maintenance and low cost. SBM machine jaw crusher is widely used in mining, metallurgical industry, road and railway construction, smelting, hydraulic and chemical industries, etc.

At Sandvik we have over a century of experience of designing and manufacturing jaw crushers. We also have a wealth of knowledge about customers' expectations and needs. This background has led to the current range of Sandvik jaw crushers which includes models specially suited for mobile applications. Strength has been increased and weight has been reduced. Sandvik’s jaw crushers provide an excellent choice when high production and low total cost are sought.

ROBUST CONSTRUCTION
The Sandvik jaw crusher is a single toggle jaw crusher, characterized by attention to detail, in both design and manufacture. We have incorporated the best of the old and applied the benefits of the latest technology. The frame consists of two side plates of rolled steel, plus hollow castings at front frame end and moving jaw which give a high rigidity/weight ratio. Large-radius transition areas reduce stress concentrations and welds are positioned in low-stress areas. The advantage of a welded frame is that it is equally strong in all directions and ensures excellent durability against shock-loads. Thus minimizing the risk of failure on the main-frame, as with a bolted construction.

OPTIMIZED PERFORMANCE
The design of the deep symmetrical crushing chamber maximizes feed size, capacity and reduction. An optimized nip angle ensures that the material progresses smoothly down through the crushing chamber to enable high reduction, productivity and superb utilization of jaw plates. It is not just a large nominal feed opening that is necessary – the feed acceptance capability depends on a feed opening which is effective and active (see illustration). All crushers in the range have an almost square feed opening so that they can accept the largest material lumps without blockages.

A thick, replaceable deflector plate protects the top of the moving jaw from the impact of the feed material. Large material lumps entering the crusher fall straight into the active region of the crushing chamber, so there is no need for a stationary cross-wall in the feed area.

Thanks to carefully engineered design, Sandvik's jaw crushers secure trouble-free operation and increased uptime.

Bearings are grease-lubricated and have grease-filled labyrinth seals to prevent the entry of dust.

As a standard, grease lubrication hoses with a central distribution block offer safety value and make it easier for the operator to grease the bearings.

Automatic lubrication system that can be connected to existing control systems for remote alarm indication ensuring protection of the roller bearings.

Setting adjustment made with traditional shim plates.

Quick and easy installation of jaw plates by using clamping and support bars to fix the jaw plates to the crusher.

Designed with sacrificial parts to protect the main components of the crusher such as frame, swing jaw and bearings. This reduces total life-cycle costs and increases uptime, as it is less expensive to change the sacrificial parts than the main components.
