In the production process of crusher machine, A&C adopts strict quality control and continuous technical improvement and innovation to make crusher machine more durable in use. A&C crusher machine has fine discharging materials and low noise, and it is electricity and energy saving and convenient and efficient. The new crusher machine is equivalent to two previous old crusher machines. Its cost is greatly reduced, and it can achieve a better crushing effect when crushing hard materials.

This equipment uses the special blade whose hardness is not lower than HRC55 (the HRC hardness of file is 51 degrees) to strengthen structure and the dense reinforcement plate to ensure the stability of the box body. It adopts automatic button for controlling, which is safe and convenient. Security identity and label also guarantee safe use safe. Besides, crusher machine can be equipped with conveyor belt for material feeding and discharging. Conveyor with a magnetic roller can better separate iron and aluminum. In the crushing process, the materials in the crushing cavity can be fully, effectively and finely crushed with high yield, low energy consumption, high efficiency and fine and even discharging. In addition, the whole system is equipped with dust removal device which can minimize the harm caused by dust pollution in the production process, so that the equipment has the advantages such as low noise, small pollution, simple operation and convenient maintenance.

A&C crusher machine is outstanding in the crushing industry for its high output, low noise, big crushing ratio and favorable price. What A&C crusher machine manufacturer always insists on is to provide customers with the best crushing equipment.

To Select Jaw Crusher Machine as Coal Crusher Machine Is a Mistake

Jaw crusher machine is almost universal crusher machine equipment, can be used for breaking many kinds of materials, with the most widely used application range in related industries. Jaw crusher machine, commonly known as the Tigers, and its principle is a kind of bionics, that is, simulate the crocodiles jaws movement, so as to achieve the purpose of items broken. Jaw crusher machine has the largest breaking ratio in all types of crusher machines, so its more generally applied to coarse work.

Jaw crusher machine can play a huge role in common stone production, powder making, sand making, breaking and ore dressing process, by breaking big material into small pieces. However, its difficult for jaw crusher machine to break coal, and the reasons are as follows.

Coal is light, and its density is far below other type of rock, only 1.5-1.7 grams/square centimeters. The raw coal dug from coal mine has relatively smooth surface, which will cause a phenomenon that some coals cant be broken when jaw board squeezes. Therefore, the production is often low if use jaw crusher machine as coal crusher machine.

The author would not like to recommend customers using jaw crusher machine for crushing of coal, because according to the different moisture content of coal, different crusher machine equipment should be chosen. If the moisture content of coal is below 8%, hammer crusher machine and inversed impact crusher machine can be selected, if moisture content of coal is high, up to 30-40%, only roll crusher machine can be chosen. For investment in coal, customers should be aware of the coal industry, and select appropriate crusher machine equipment for crushing coal with different moisture content.

Structure and Functions of Crusher Machine

1. Gyratory crusher machine is mainly used for coarse crushing and it belongs to coarse crusher machine which is mainly used for crushing all kinds of ores and rocks with medium or above medium hardness. It is mainly composed of transmission part, engine base, eccentric sleeve part, crushing cone, central frame, beam part, driving part, oil cylinder, hydraulic part, pulley part, electrical part and thin oil lubrication part. The structure and function of each part are as follows:

   1) Transmission part

   The main function of transmission part is that when the eccentric sleeve rotates, it drives the main shaft to rotate together with the movable cone spindle pressed on it. The central line of the movable cone will rotate along the cone trajectory with the fixed hanging point on the beam as the vertex.

   2) Engine base

   The engine base is the main component of cone crusher machine and it is fixed on the ground by foundation bolts. There is steel lining sleeve set in the sleeve of the engine base, and eccentric shaft sleeve rotates in the lining sleeve.

   3) Eccentric sleeve part

   Eccentric shaft sleeve is a major part that bears the crushing force.

   4) Crushing cone

   Crushing cone is supported by the bottom hydraulic oil cylinder and its upper part inserts into the cone lining sleeve of the beam central hole. When the crusher machine rotates, as the bottom part of the cone lining sleeve is cone surface, the requirements of rotary pendulum motion the movable cone can be met.

   5) Central frame

   There are four parallel rows of lining plates inside the central frame. When installing the lining plates, finally install the base plate to ensure the firm combination. The downmost row of plates supports on the boss of the bottom of the frame and the upper row inserts into the convex edge on the upper part of the central frame, so it can sustain the pushing force, crushing force and vertical separating force produced by frication when crushing ore.

   6) Beam part

   Fix the beam on the central frame with pin rolls and there are lining plates on the beam reinforcement and the outer ring.

   7) Base part

   The base part gives us mutual location and base level of each part of foundation bolts as well as the flexure value of the equipment.

   8) Oil cylinder

   Oil cylinder is installed at the bottom of the frame and it supports the crushing cone and bears the axial force when crusher machine works.

   9) Pulley part

   Pulley parts are used to remove the oil cylinder and it is composed of idler wheel, slide track and car.

   10) Lubrication parts

   To lubricate all the frictional parts, the crusher machine is equipped with special dry and thin oil lubrication device.

   11) Electronic control system

   The electric control system has three operation ways: local manual control, local automatic control and remote control from the central control room.
