Which is better for the chemical rust removal method and the high pressure water mill rust removal method of the sand making machine?


The sand making machine is generally made of steel material, and the sand making machine equipment is working in the open air environment for a long time. Coupled with the rainy summer, it is easy to rust. For a long time, the equipment production capacity It will fall. Therefore, it is very important to choose a suitable descaling method. The following two methods of descaling are the chemical descaling method and the high-pressure water mill derusting method.
1. Chemical descaling method. This method removes rust from the surface of the crusher by acid, but the drawback of this method is that it can only be used in the workshop. Pay attention to safety when using, and avoid direct contact with the body.
2, high pressure water mill rust removal method. This method uses the strong impact of the high-pressure water jet to remove the rust on the steel plate, which does not generate dust or damage the steel plate. The rust removal efficiency is high and the effect is obvious. The disadvantage is that the anti-rust problem is easy to occur.
The above are two kinds of descaling methods that we have summarized. The specific method of derusting should be selected according to the actual situation of the manufacturer. No matter which method has its advantages and disadvantages, it is said that the sand making machine manufacturers do not have to worry about which method to use, as long as it is suitable for themselves, it is convenient.

Mobile crushing station to help build construction waste to create a sustainable force


With the rapid urbanization process, a large amount of construction waste is generated. The construction waste components are composed of waste bricks, concrete, rock, scrap iron wire, steel bars, electric wires, etc. These materials can be recycled and reused after processing, so the reasonable disposal of these construction wastes has become the focus of increasing attention.
China’s construction waste crusher started late, and the treatment of construction waste is imminent. Now the demolition of the city and the urbanization of the countryside have produced a large amount of construction solid waste. Due to the dumping and landfilling of these wastes, not only the land but also the temperature is occupied. Under the action of water, the wastewater generated by fermentation and scouring causes serious pollution to groundwater and air.
The recycling of construction waste is a systematic project. We must attach great importance to improving the technical treatment level of construction waste. Most of the construction waste can be reused as renewable resources. For example, waste concrete and waste masonry can be crushed once by using a mobile crushing station. The coarse and fine aggregates can be used to produce concrete of the corresponding strength grade, mortar or preparation. Building materials such as blocks, wall panels, floor tiles, etc.
After adding the solidified material to the coarse and fine aggregates, it can also be used for the road pavement base. The waste bricks are burnt clay materials. When crushed and ground into powder materials, they have pozzolanic activity and can be used as concrete admixtures instead of fly ash, slag powder and stone powder. The mobile crushing station is a construction waste crusher tailored for construction waste in recent years. It can crush construction waste and then generate sand for building materials, which is very environmentally friendly.
The mobile crushing station is mainly used for metallurgical, chemical, building materials, hydropower and other materials that need to be relocated, especially for the operation of mobile materials such as highways, railways, hydropower projects, etc. Users can scale according to the type of processing materials. Different configurations are required for the finished material.

Classification and advantages of common crushing equipment


In the mining machinery market, there are many kinds of Zenith Crusher. Among them, common crushing equipments include: jaw crusher, impact crusher, cone crusher, hammer crusher, mobile crusher, etc., facing many crushing equipment, customers It is difficult to choose. Today, ZENITH machines are analyzed from the classification and performance advantages of common crushing equipment, which is convenient for users to purchase.
1. Jaw Crusher
The smashing is mainly a kind of rough breaking equipment, which is mainly used for crushing various materials with compressive strength not exceeding 320 MPa. It is often used in the crushing stone production line. The performance advantages of the jaw crusher are many, for example: wear resistance The material structure with good performance guarantees the wear resistance of the wearing parts and prolongs the service life; the structure design is reasonable, the discharge port is adjustable, the breaking capacity of the different materials is improved, the adaptability is strong, the structure is simple, and the maintenance is convenient. The deep cavity design without dead zone greatly improves the production output of the jaw crusher.
2, impact crusher
The impact crusher is abruptly used for crushing. It is mainly used for crushing various medium and hard materials with a particle size of not more than 120-500mm and a compressive strength of not more than 320pa. It is mainly used as a two-stage crushing equipment and a counter crusher in the crushed stone production line. The performance advantages are as follows: the feed port is large, the bulk material can be crushed; the crushing cavity is deep, and the production yield is high; the wearing part of the wearing part is made of new material and new technology with good wear resistance, which reduces the replacement frequency of the wearing parts. Increases the service life of the impact crusher.
3, cone crusher
The cone crusher is called cone crushing. It is mainly suitable for crushing all kinds of mining materials with hard and medium hardness. It is also used as the second-stage Quarry crusher in the crushed stone production line. It is generally divided into spring cone crusher and hydraulic cone crusher. The performance advantages of the cone crusher are as follows: the spring safety device is adopted to reduce the downtime, the production yield is high, the equipment operation is safer; the internal sealing of the structure is good, the dust pollution is reduced; the structure is simple and easy to maintain.
4, hammer crusher
Hammer crusher is abruptly broken, mainly used for crushing and crushing of materials with a compressive strength of not more than 100 MPa and a humidity of not more than 15%. Performance advantages of hammer crusher: low investment, fast profit, short recovery period; simple structure, high output; large crushing ratio, uniform output; easy-to-wear hammer head with high-quality wear-resistant alloy steel material, long service life.
From the above analysis, we can see that the nature and advantages of the crushing materials of different crushing equipment are not the same, can not say which one is good, which is not good, specific analysis, the user is also the same when purchasing To understand the nature and size of the material to be crushed and the demand for the size of the material to be crushed, when purchasing the crushing equipment, be sure to shop around and communicate with the technicians of the manufacturer to choose the crush that suits you. device.
