Stable Construction Market

Concrete batching plant tower 1. The tower has a blocking design, easy to install and transfer. 2 The control room and the tower are separate, easy to repair, without shaking and exam. 3 The door of transition storehouse has a special cone crusher designed structure, cooperate with electric control system; It can open for a second time, to meet the needs of high capacity concrete mix. 4 Utilice color steel sandwich board as the out casing has a function of heat preservation, heat insulation.

Inside of the room, it is equipped with dust catcher, avoiding pollution. Hay num’axes stream fan in the mixing floor and weighing floor, according to the national environment protect regulation, it can form a cross-ventilation in and out tower. Contractor NCC said demand in the Nordic construction market was stable during the first half of the year after it reported an increase in sales but drop in net profit for the period. Liquid weighing 1. To meet the demand of high-speed railway construction, the equipment has two liquid weighing for the user to choose. According to the demand of customer, the ratio is changeable. 2 With liquid hopper, adopting temporary extractive weighing structure, the weighing precision is improved.

3 The equipment can be equipped with pump and butterfly valve which can work at 80 c, if the tubes and carry out in cold winter. NCC said net sales were up from SEK13 billion (1.6 billion) in the six months to 30 June last year to SEK14 billion (1.7 billion) in the first half of 2012. Net profit fell from SEK369 million (45 million) last year to SEK341 million (41 million) in the first half of 2012. The company s construction units in Denmark, Finland and Norway reported improved earnings, with higher volumes and stronger margins. At the same time, earnings in Sweden declined due to impairment losses on projects. Construction output in from the European Union (EU27) fell 5.8% year-on-year in June, while output from the Eurozone fell 2.8%, according to the latest figures from Eurostat. NCC said the construction market was strong in Norway, while demand was weaker in the company’s other markets, primarily in Denmark and Finland, resulting in an overall stable picture for the region. The market trend is difficult to assess and NCC does not expect construction investments to grow significantly in 2012, the company said. This makes June the sixth consecutive month since the start of 2012 in which construction output declines have been recorded. The largest annual decreases for June were registered in Portugal (- 18.9%), UK (- 15.5%), Hungary (- 11.1%) and Slovakia (- 11.0%). Year-on-year increases in construction ball mill output were recorded in Sweden (4.6%), Germany (3.0%) and Romania (0.1%).

Represent Jaw Crusher Specifications

How to represent jaw crusher specifications The specifications of jaw crusher are represented with a B and width to length l. For example, 900 1200 mm jaw crusher refers to the mouth width is 900 mm, and length is 1200 mm. According to the width of jaw crusher material inlet, it can be divided into large, medium and small three types. Material inlet width greater than 600 mm is large type that, width between 300 to 600 mm is the medium type and width of less than 300 mm is small type. In production, the biggest block should be smaller material feeding 15 to 20% than the inlet width B, that is the largest block D = 0.85-0.8B. Working Principle of Jaw Crusher This type of crusher adopts the electric motor as the power.

The eccentric shaft is revolved by an electric motor through v-belts. It causes the swing jaw to follow the preconcerted circle and crush the feeding materials, and then the material will be broken in the crushing chamber which is consisted of the stationary jaw plate, swing jaw plate and the liner plate. The materials are discharged from the lower part of machine. There are two common kinds of Jaw Crusher: dodge type and Blake type. Due to the throat width constant and often be keep so as to affect the normal work, the dodge typehas been eliminated. While Blake type is widely used in concentrator. Jaw crusher consists of the following major components: fixed jaw plate (the front wall of the rack, hanging in the axis of the movable jaw), eccentric shaft, vertical rod, brackets, drive flywheel, two jaw liners, levee, elbow board seat and adjusting block spring board.

Technical Features Introduction

Mineral Impact crusher is suitable for crushing the hard materials, such as limestone crusher in the cement plant, having the advantages of large production capacity, small particle size. This series of products can handle the materials whose side length is 100-500 mm, having the advantages of high compressive strength which ups to 350 MPa, large crushing ratio, the pipes are broken cube tablets, and so on. Working Principle of the mineral Stone crusher directamente fall into the high speed rotating table from the upper part of the machine; under the effect of high speed centrifugal force, turntable with the flying stone which appears as the umbrella type, after the collision force against each other, the frequently hit, friction and crushing are produced by the eddy motion between the rotating plate and casing, and the products are discharged by the lower part, the closed multi-cycle are formed, the screening equipment control the particle size. Performance characteristics of the mineral impact crusher High chrome hammer, counterattack lining wear; a unique gear counterattack liner; It is particularly suitable for hard Rock crushing, energy efficient; the entire board structure nesting appeared as small particle size and the cube-shaped, without internal pattern; product shape shapes cubic, the nesting particle size is adjustable to simplify the crushing process. Technical Features of the mineral impact crusher 1, multi-cavity evenly crushing, it is suitable for crushing hard rock. 2, low port for easy feed produces the line layout and increase the size of the feed.

3, open the full hydraulic, for the convenient of maintenance and wearing parts replacement. 4, new wear-resistant material makes the life of plate hammer, counterattack lining forrada trial are much longer. Type of the mineral impact crusher According to their structural characteristics, The mineral impact Crusher can be divided into the single-rotor impact crusher (back-breaking) and dual-rotor impact crusher (back-breaking). As to the rotor turning, rotation crusher can be divided into the reversible and irreversible rotating these two types, single-rotor impact crusher points. The dual-rotor impact crusher can be divided into the same direction as the rotation, reverse rotation and opposite rotation these three types. According to the internal structure, single-rotor impact crusher is divided into two forms, that is, with Leveling the grid plate and with a neat and well-spaced grid plate. The double rotor impact crusher can be divided into the following two types: the rotor at the same level and the rotor are not on the same level.
