In the mining industry, crushing equipment can be said to occupy a considerable part of the proportion of the crushing equipment sales personnel may often be asked such a question. For example，Is this crusher the same as that one? Or what is the difference between these two crushers? Each device is unique in its own way. Today let me discuss with you if the double stick crusher and high-pressure roller are the same? What's the difference?
Is The Primary Sizer Crusher The Same As The High Pressure Roller Mill?
First of all, I would like to say that the primary sizer crusher and the high-pressure roller mill are two different pieces of equipment, which can be seen from the appearance. Besides, the primary sizer crusher is also known as roll crusher, double roll mineral sizers. A high-pressure roller mill, also known as "roller press", "extruder", is high efficiency and energy-saving new technology crushing equipment developed by the principle of static crushing. It is the preferred equipment for realizing "more crushing and less grinding" in the domestic mining industry at present.
The Composition And Characteristics Of Primary Sizer Crusher
The Double Sizer Crusher appeared in 1806, has more than 200 years of development history. The crusher is composed of two parallel rollers which is fixed roller and moving roller. After the equipment is started, the material will enter the crushing chamber. With the moving roller moving slowly to the fixed roller, the gap between the two is gradually reduced, so as to achieve the purpose of crushing.
The working surface of the roller can be smooth (such as the back roll), groove (such as the front roll), or tooth surface according to the user requirements. Furthermore, in order to strengthen the crushing of materials at work, the rotation speed of the two rollers can be inconsistent.
The Composition And Characteristics Of High Pressure Sizer Crusher
High-pressure Sizer Crusher is composed of frame, high pressure working roller, hydraulic system, and feeding system. First of all, the working parts of a high-pressure sizer crusher are a pair of high-pressure rollers which are arranged in parallel and rotate opposite to each other. Each roll is driven by an electric motor through a planetary gear reducer, the position of the fixed roller is fixed, and the moving roller can move on the horizontal slide. As a result, the hydraulic system on the sliding roller shaft provides extremely high working pressure (up to 300MPa) to the work roll surface.
A high-pressure roller mill is a kind of high efficiency and energy-saving new technology crushing equipment developed by using the static crushing principle.
This equipment is through the application of static load high pressure to the ore, so that its internal is greatly damaged and many cracks, or even squeezed into finer particles, so as to greatly reduce the workload of subsequent grinding, to achieve the purpose of increasing production and saving energy.
Two Aspects To Distinguish The Difference Between Double Roller Crusher And High-Pressure Roller Mill
1. Different Working Principles
A high-pressure roller mill is to rely on two solid crushing rollers of relative rotation. When the material passes through the distributing device of the equipment, it enters the roller gap of relative rotation (V-shaped crushing chamber). The principle of high-pressure material layer crushing is adopted, and the material is extruded under high pressure (the general pressure is set as 150Mpa).
The primary sizer crusher is suitable for crushing and fine crushing of solid materials with compressive strength less than 250mpa and water content less than 35%, such as crushing iron ore, quartz stone, potassium (sodium) feldspar, limestone, river pebbles, and other materials. In addition , the primary sizer crusher can be widely used in mining, thermoelectricity, cement ceramics, metallurgy, chemical industry, building materials, and other industries, with low maintenance costs, low water requirements, reliable performance, less power consumption, less dust, low noise characteristics.
2. Different Ways Of Protection
The crushing capacity of the roller crusher is large, the motor and the reducer are connected by a limited distance hydraulic coupling, to prevent power overload. What's more，the roller crusher equipped with sensor overload protection is safe and reliable. Hydraulic system pressure stability, easy to adjust; The application of sensing technology to make overload protection more safe and reliable; The press roller adopts the welding process of a large roller press to ensure that the hardness of the roller surface is greater than that of the hydraulic series roll crusher.
