Nearly 20 vertical shaft impact crusher-producers has grown considerably. The past, the company has been the development of Tidco ore - vertical ore crusher technology major manufacturers now, the production of such equipment manufacturers have Svedala Barmac company, Canica-Jaques The company is also in the production ore - metal crusher respect in the international community more successful a factory. The production of better equipment, improved. These companies believe that to increase its advantages and minimize its shortcomings in the design, can effectively promote the work of the support. 
          
           Ore - ore crusher
            
           New Zealand Svedala market information company spokesman Kevin Tappin, 25 former ore - Ore vertical shaft impact crusher-Rotopactor broken the advent of principle, the mineral processing industry has undergone tremendous changes. Since Rotopactor equipment since the advent of in the design done a lot to improve. Bauma company will introduce new Duopactor 1100 series. Crusher in the original design improvements in the programme, was identified as one of the components of the broken equipment. Clearly, in the design of the Rotopactor some attention to the inherent constraints. Despite these limitations do not affect the quality of products, but the impact of production capacity, its causes is Rotopactor crusher downtime for maintenance for a long time.
             
            As introduced serial-feeding system, Barmac Roto-pactor product line development to Duopactor1000 series. The second system will be expected to feed into the rotor flow channel markers in the crushing chamber, which would allow equipment to double the production capacity without increasing energy and operating costs. Another advantage is to raise the grade of the nesting capability. Duopactor equipment, the handling capacity of 650 t / h, maximum size of more than 500 mm, product size range 0.06 to 12 mm. Since 1000 Series Duopactor since the advent of Practice has proved that it is a produce asphalt pavement, concrete materials and special gravel mixed materials of high quality equipment. It is very applicable to a variety of broken materials, such as metal ores, mixed materials or industrial materials. Barmac high-speed impact crusher to reduce noise and improve the forming of the stone to reduce the product moisture, easing the screen, at the same time to produce quality products at minimal cost. Ore - the interaction of ore to make the equipment more broken abrasive materials, and the rotor design for the further improvement of the equipment to reduce the wear rate.
             
                Barmac crusher efficient production function granular material products, such as ball mill feed, or for sintered material to heap leaching of materials handling, therefore, it is an alternative to the high cost, low efficiency breakinggrinding mill broken equipment broken machine. If the need to increase the mill's output will be Barmac crusher added to the existing production line can be broken greatly save money.
            
           Barmac Duopactor 1100 Series crusher
             
           Since Duopactor obtain a patent, the company Svedala for further development of the equipment invested considerable technical strength, design a new type of Barmac Duopactor 1100 series - "user friendly" Barmac crusher and make investment has paid off. Barmac crusher serial control system equipment is the key to produce the best output.
           Barmac design team recognized this problem and developed a serial control system, which not only allows the operator to visually serial door positions, but also access to the rotor and serial material flow control precision.
             
           Breakers has been the reliability of vsi crusher -operator made recommendations to improve one aspect. When the equipment can be made by the operation can only be the work of broken equipment efficiency, but this is only common sense. However, in the development of vertical shaft impact crusher, design and producers do not see this as an important feature. Recently, the people hope that the broken equipment production time is longer, thus to reduce the crushing machine for the production and maintenance time increases the pressure on staff. Svedala Barmac in the design of the new 1100 Series equipment and user cooperation crusher reliability of the work of the special standards developed.
             
          1100 Series products Duopactor Barmac crusher in the market, its rotor also adopted a new design. Wear parts of the rotor and the rotor has been improved greatly enhance the work efficiency, but also makes materials in the particles in the rotor to shorten the period of detention. These improvements result from an efficiency is lower than the power demand, and to increase the capacity utilization of a small motor can be set to enhance the capacity of the electrical capacity. Another efficiency is greatly reduced costs per ton of wear and extended maintenance interval. Svedala Review concluded that the company's 1000 Series product development based on the success of the new Duopactor
           1000 Series products - BarmacB9100 was launched in Bauma 98 - designed to improve the following:
             
              
              To improve the capacity of the motor in their work;
             Ease of maintenance;
             Improved control of the product;
             Reducing operating costs.
           
            These results attributable to the acquisition of the hopper, serial system, the rotor and wear parts design improvement. Production capacity is expected 25% increase. Because of the increased size and the expected increase in output. Specific energy consumption (kWh / t) decreased by 20% and therefore, the crusher makes high-tariff countries have good economic returns. Depend on the actual characteristics of raw materials and equipment operating conditions. B9100 Duopactor
           Model is a new series of the first, was launched in 1998.
          Ore - Metal Crusher
           1974, Messrs Bartley and Macdonald began eyes Rotopactor products, another company in the Pacific began to the other side of the production shaft impact crushers. However, Vancouver and Washington-based company aimed at the Canica ore - Metal broken system, namely to design an improvement of the existing equipment can be patented crushing chamber. Users will inevitably asked obvious questions and the first Canica vertical shaft impact crusher-style construction in 1975. Today, the company still ore - Metal firmly believe in the superiority of equipment, particularly in the broken particle size and the design of materials forming ability. Not long ago, Evans Deakin The company was purchased by the industrial group with Australia and the crusher plant Jaques joined together to form a Canica-Jaques crusher manufacturing companies.
           The new company has invested in the construction of a new Vancouver plant and equipment that is directly reciprocated. Recently, in the international market by the delivery of equipment including Belgium Grales quarry two broken equipment, the quarry is to provide gravel for the TGV railway. Two 125-and two 100-type operations with the old crushing machine. Canica-Jaques said, the railway industry, this gravel specifications are extremely stringent. By the use of gravel is a very hard and abrasive strong porphyry. Canica said that although "real impact crusher" not handling ore - ore crusher of the secondary crusher, but it does provide is a good material for the size and shape of broken equipment, and in this regard with some of its Advantages:
             
             Crushing chamber geometric design patent will have a low speed impeller, which can reduce the power required. Many broken cavity structure can be used for special use <br>
           Passers-by, of all sizes hopper, platform, and the anvil iron impeller also can be suitable for immediate work.
             Wear parts of the geometric shape basically designed to keep the initial angle. This means that due to wear and tear caused material change is a very small particle size. Thus maintaining a high quality production and screening efficiency. Wear components containing 28 per cent of the chrome tin, without welding and surface hardening.
             
           At present, Canica-Jaques production lines include: maximum capacity of 800
           T / h to 155 for the type and production capacity of 750 t / h of 125 secondary crusher; production capacity of 500 t / h of 105-second / third breakers; 100,90,80 and 65 three-breakers . Such equipment in the largest production capacity from 800 to 125 t / h. 100 equipped with standard and optional for dust control systems. The company also provides equipment of commercial sexual services. The company, improved anti-wear life of the equipment used other than iron and anvil impeller system crusher increased by 2 to 3 times.
