There are many types of crushing equipment used in the industry, and there are many classification methods. The crushing equipment can be divided into: jaw crusher , cone crusher , roller crusher , impact crusher and grinder according to working principle and structural characteristics.

1. Jaw Crusher

The jaw crusher is crushed by pressing the jaws periodically to the fixed jaws, crushing the material sandwiched between the jaws.

According to the trajectory of the moving movement, it can be divided into a simple pendulum jaw crusher and a complex swing jaw crusher. The jaw crusher, commonly known as the "Tiger Port", is one of the longest-established crushers and is still the most effective equipment for crushing hard materials.

2, cone crusher

The cone crusher is a conical surface that is moved by means of a swirling motion, and is periodically close to the fixed cone surface, so that the material of the two tapered surfaces is crushed and bent. It can be divided into a gyratory crusher for coarse crushing and a cone crusher for medium and fine crushing.

3, roller crusher

The working part of the roller crusher is two relatively rotating rollers. The surface of the roller can be toothed, called a toothed roller crusher. It is mainly composed of splitting and crushing and crushing. According to the number of tooth rolls, it can be divided into single tooth roll, double tooth roll and multi tooth roll crusher.

4, impact crusher

Both the hammer crusher and the impact crusher are impact crushers. The crusher has a high-speed rotating rotor with an impact hammer. When the material enters the crusher, it is crushed by a high-speed rotating hammer or energy is obtained from a high-speed rotating rotor, which is thrown at a high speed to the crusher wall or specially designed. The hard board was crushed.

5, grinding machine

The grinder is a hollow cylinder with hollow journals at both ends, the material entering from one end of the cylinder and the product exiting from the other end. Grinding medium (steel ball, steel rod or gravel) is installed in the cylinder. The grinding machine is divided into a ball mill , a rod mill or a gravel mill depending on the grinding medium. When the cylinder rotates, the medium is brought to a certain height and falls, which causes impact and abrasion on the material to crush the material.

Low Temperature Scouring and Bleaching

Low temperature scouring agent relates to the pretreatment process of printing and dyeing industry. The invention is scientifically prepared by efficient surface active agent and effective chemical additives, and can complete desizing, boiling and bleaching treatment of cotton and linen, chemical fiber and blended fabric at 45℃ ~ 60℃ for 1 hour, effectively remove the size, cotton seed shell, pigment and impurities on the surface of the fabric, improve the whiteness of the fabric, and almost do not damage the fiber. The invention has the advantages of energy saving, short process flow, improving quality and reducing labor intensity of workers, and has obvious economic and social benefits.

Low temperature scouring and bleaching, low temperature pretreatment auxiliary, cold-pad-batch, batch-steaming, continuous pad-steaming process
