Dolomite Crusher

Product introduction

Dolomite crystals belong to the trigonal system of carbonate minerals. Dolomites are often produced in interbedded layers with siderite and limestone layers.In lacustrine sediments, dolomite coexists with gypsum, anhydrite, rock salt and potash salt.

Dolomite is the main mineral component of dolomite and dolomitic limestone.Dolomite can be used in building materials, ceramics, glass and refractory materials, chemical industry, agriculture, environmental protection, energy saving and other fields. It is mainly used as a flux for alkaline refractories and blast furnace ironmaking; production of calcium magnesium phosphate fertilizer and preparation of magnesium sulfate; and ingredients for the production of glass and ceramics.

Working principle

In the process of crushing the huge dolomite into small dolomite blocks, the dolomite material is poured into the crushing chamber containing jaw teeth from the top entrance.The jaw teeth push the material against the wall of the chamber with great force, breaking it into smaller stones.Supporting the movement of the jaw teeth is an eccentric shaft, which penetrates the body frame.Eccentric motion is usually produced by flywheels fixed at both ends of the shaft.Spherical roller bearings are often used for flywheel and eccentric support bearings. The bearings must withstand huge impact loads, abrasive sewage and high temperatures.Finally, the broken dolomite is discharged from the discharge port.

Components

1. Rack. The rack is composed of front wall, back wall, side wall and rail components. It is subject to a large impact load during work, so it should have sufficient strength and rigidity, and be checked by finite element analysis and calculation.

2. Move the jaw. The movable jaw is a component that supports the tooth plate and directly participates in crushing the ore. In order to reduce the weight of the movable jaw, the non-box type is adopted in this design (the movable jaw bears a lot of pulling force during work).

3. Tooth plate. Although the structure of the parts directly in contact with the ore in the dolomite crusher is simple, it will affect the productivity of the jaw crusher, specific energy consumption, product particle size composition and particle size, and crushing force,the tooth plate bears a great impact, so it wears very badly.

4. Toggle. The bracket is a relatively simple part, but its function is very important. In order to improve transmission efficiency, reduce wear and extend its service life, most of them can adopt rolling structure.

5. Flywheel. The flywheel is used to store the energy during the idle stroke of the movable jaw, and then used for the working stroke, so that the working load of the machine tends to be uniform. The pulley also functions as a flywheel.

Performance advantage

1. The dolomite crusher uses the jaw plate to press the material into it, and the movable jaw plate partly moves downward with the material, thereby accelerating the discharge speed and improving the production capacity. Practice has proved that,the production capacity is 20%-30% higher than other crushers.

2. According to the investigation, the dolomite crusher can produce 1,000 tons per ton, and it can save electricity by 20%, which is more energy-efficient than other crushing equipment.

3. It adopts a variable tooth angle curve cavity shape, and realizes full cavity crushing through reasonable design of the tomb and length of each part of the cavity shape, which not only ensures the uniform shape of the machine product, but also improves the passing capacity of the machine.

4. High safety performance, using multi-functional mechanical, hydraulic, electrical protection systems and other technologies. When the machine is overloaded, the mechanical protection safety clutch quickly disengages the main shaft and pulley of the dolomite crusher, causing the machine to run idly, and at the same time an alarm is issued.
