Raymond mill is a kind of ultra-fine grinding equipment suitable for processing ore grinding powder. It is fed once and becomes powder once, and the fineness can be adjusted between 50-500 mesh. Raymond Mill processes mainly ore, and the quality of its accessories is very important. The maintenance and service life of the accessories affect the production process.
Raymond Mill Parts-Grinding Roll
First of all, I introduce the more important accessory of Raymond Mill-the grinding roller. The working principle of the Raymond mill is that the grinding roller is crushed by the suspension roller and air separation under the action of centrifugal force. The grinding roller is cylindrical, and there is a hole in the middle to place the grinding roller shaft. This hole is a tapered hole, with one big end and the other small. The quality of the grinding roller directly affects the service life of the Raymond grinding equipment. If you want the grinding roller has a longer service life, it is important to choose the material. There are mainly three kinds of grinding roller materials, 65 manganese, manganese 13 and high complex alloy. These materials are basically more durable when processing ordinary materials. But for some special, harder materials that need to be ground for a long time to become powder, you need to choose more durable materials, such as manganese 13 or high complex alloys.
A grinding roller in small equipment weighs more than ten kilograms, and a grinding roller in large equipment weighs more than 200 kilograms. Therefore, the price of grinding rollers in large equipment is relatively high. Users should consider production costs when choosing equipment and accessories. Questions, choose carefully, and choose the one that suits you according to your needs. It is not necessary that the bigger the better.
Raymond Mill Parts-Grinding Roller Assembly
The main component hanging on the plum blossom stand in the main engine of Raymond Mill is the grinding roller assembly. The total achievement of Raymond Mill's grinding roller is like a spare tire of a car. If the grinding roller is broken or the bearing inside is broken, you can take out the grinding roller assembly and replace it with a new set when it needs repairing, that don't affect production. The upper and lower glands of the complete package of the grinding roller assembly, the grinding roller shaft, the grinding roller, the bearing, the housing of the grinding roller shaft, and the locking screw under the grinding roller.
There are two types of grinding roller assemblies for Raymond Mill parts. One is the old-fashioned type with butter, which needs to be added once a day; the other is the new type with oil, and the oil is added once a week. The Raymond mill assembly needs to be oiled and maintained, so that the bearings inside will be more durable. The price of a set of grinding roller assembly is much more expensive than that of a grinding roller, a small one weighs more than 50 kilograms, and a large one is about 500 kilograms.
Raymond Mill Parts-Grinding Ring
Another important part of the Raymond Mill, the grinding ring, looks like a large circle with a tapered inner circle, with one large end and one small end. The grinding roller rotates and rolls in the inner circle of the grinding ring. Generally, it is necessary to replace the grinding ring once when replace the grinding roller twice. Its material is also the same as the grinding roller. There are mainly three kinds of manganese 13, high-melting alloy and 65 manganese. The user can choose the suitable grinding ring according to the processing material and actual conditions.
It is troublesome to replace the grinding ring. It is necessary to remove the grinding roller assembly and the quincunx, and then use a jack to slowly push it out or directly destructively use air cutting to cut the grinding ring into several sections and it is easy to take it out. When buying a grinding ring, be sure to measure the size. After the new grinding ring is placed directly, the surface of the grinding ring should be 3-5 cm higher than the air duct, and then use a press to press in or use a sledgehammer to slowly drive in, until the plane of the grinding ring reach the plane of the air duct.
Raymond Mill Parts-Plum Flower Stand
There is a shelf fitting in the main unit of Raymond Mill that looks like a plum blossom. We call it a plum blossom stand. Its main function is to suspend the grinding roller assembly. The three, four or five grinding roller assemblies of Raymond Mill are suspended on the plum blossom frame. The plum blossom stand is a casting, with three, four and five claws. Choose a suitable plum blossom stand according to the several grinding rollers of your own Raymond mill. It should be noted that the user needs to take out the grinding roller assembly when replacing the grinding roller. After the replacement of the new grinding roller is installed, when installing the grinding roller assembly, it is necessary to balance the several grinding roller assemblies to avoid causing Deformation and damage of the quincunx.
There is also a little trick about the rubber sleeve. Many users often change the rubber sleeve. Why is this? The rubber sleeve is sleeved on the cross arm shaft of the grinding roller assembly. When installing the rubber sleeve, the top wire should be tightened until it can not be screwed any more, and then gently loosen 1-2 wires, so that the rubber sleeve It will not wear out too quickly.
Raymond Mill Parts-air duct plate
The air duct plate is a casting, it is very difficult to process, so the Raymond mill air duct plate is a relatively expensive accessory in the main machine. The wind blown by the Raymond mill fan rotates through the action of the air duct disc, and then walks to the upper part of the main engine. The accessory grinding ring of the Raymond mill is placed in the inner circle of the air duct disc, so be sure to observe the wear condition of the grinding ring during maintenance. If the grinding ring is worn out, it will easily be worn to the duct disc, it is very troublesome to replace the air duct plate. If your grinding ring is replaced in time, it will not be worn to the duct plate.
