Every time before the construction waste is started, it is necessary to carry out no-load operation and check the pipeline for leaks or other abnormal phenomena to avoid damage to the wearing parts. Operators should periodically inject new oil into the fragile parts of construction waste to maintain the lubricity of the consumables and replace the butter when needed. The broken knife is an accessory that is easily damaged in the construction waste. During the crushing process, if the material is mixed with other iron materials and impurities, the blade will be damaged, so a filter is installed at the inlet. Screen out the material. If you want to extend the use time of Construction Waste Crusher consumable parts, an effective method is to ensure the stability of the voltage during operation, not to be high or low, and to avoid overloading the equipment for a long time. Construction waste is a machine used to smash construction waste. The so-called construction waste is what we usually

From the physical phenomena and geometrical characteristics of ore crushing and ball mill grinding process, grinding is the continuation of crushing ore, which is a process of reducing the size of a nugget or ore. However, from the thermodynamic point of view, grinding is a process of internal energy increase. The grinding machine works on the ore block and overcomes the cohesion of the ore block to break it. Therefore, grinding is a process of mutual transformation. The electric energy input by the power grid is converted into mechanical energy by the electric motor, and the mechanical energy works on the grinding machine and the medium through the transmission system, and becomes the mechanical energy of the grinding medium of the ball mill. When the grinding medium falls or rolls down, it works on the ore. The work of the medium becomes the deformation internal energy of the ore, which causes the ore to deform and break. After the ore is broken, it becomes the new surface energy of

Under normal circumstances, the dimensional accuracy of precision casting is affected by many factors such as the structure of the casting, the material of the casting, the molding, the shell, the roasting, and the casting. Any setting or unreasonable operation will change the shrinkage of the casting. The dimensional accuracy of the casting is deviated from the requirements. The following are factors that can cause defects in the precision of precision castings: (1) Influence of casting structure: a. The wall thickness of the casting is large, the shrinkage rate is large, the casting wall is thin, and the shrinkage rate is small. b. The free shrinkage rate is large, which hinders the shrinkage rate. (2) Influence of casting material: a. The higher the carbon content in the material, the smaller the linear shrinkage rate, and the lower the carbon content, the larger the linear shrinkage rate. b. The casting shrinkage of common materials is as follows: casting shrinkage K = (LM-LJ) / L

Precision casting is a casting method in the modern traditional casting process. It can obtain relatively accurate shapes and high casting precision. When designing and manufacturing products, it should be carried out by a relatively good casting method. The metal material obtained by casting a wax after a series of castings can obtain a relatively high-precision finished product after sand cleaning, and can be heat-treated or cold-worked according to the needs of the product. So what are the main advantages of the silica sol precision casting products produced in this way? The use range of precision casting is relatively wide, the production mode is convenient, and a large amount of scrap metal and renewable resources can be used, and the consumption is less. The cost is relatively low and the overall economic performance is good. When casting high dimensional accuracy and high surface finish, the products produced in this way can reduce the amount of machining work, save a lot of ma

In the production process of Raymond Mill , the hardness, water content and impurities contained in the processed materials play an important role in the equipment. At the same time, Raymond's blade will also affect the production capacity of the equipment. Today, Shanghai Shanzhuo Heavy Industry introduces how the blade can hinder the productivity of Raymond Mill. First, we should all know that in the production of Raymond mill, the blade mainly scrapes the material and sends it to the grinding roller and the grinding ring for grinding. The lifting position of the blade is too high, and some are biased. Low, so that the material scooped by the blade can not be accurately sent to the grinding position, which greatly affects the production capacity of Raymond Mill. Second, the size of the blade has a direct relationship with the production space of Raymond Mill. If the space is too large, it will not be put in, and it will affect the normal operation of Raymond Mill . If it is too

In the stainless steel casting process, the pore problem often occurs, which causes a lot of troubles for the stainless steel casting processing. The pore is the bubble defect formed by the deposited gas remaining in the ingot during the cooling and solidification of the metal liquid. Let's analyze the main reasons for the generation of pores: 01. The permeability of the coating is poor or the negative pressure is insufficient. The gas permeability of the filling sand is poor, and the gas and residue in the cavity cannot be discharged in time, and the pores are formed under the filling pressure. 02. The pouring speed is too slow to fill the sprue cup, expose the sprue, entrap the air, inhale the slag, and form the venting hole and the slag hole. 03. Foam model gasification decomposition generates a large amount of gas and residue can not be discharged into the mold in time, foam, paint layer filled dry sand is poor drying, surrounded by high temperature of liquid alloy, cracking a

There are two main types of dewaxing casting methods: the Solid Mold method and the Ceramic Shell Mold method, the latter being the former method of improvement. The shell mold method until the wax type is produced in the same way as the solid mold, but after one damp and sand (or floating sand), the mold-free operation is not carried out, but the dipping and sanding are repeated several times. Until the predetermined shell thickness is obtained. Drying, heating, melting and waxing, high temperature heating and casting, this method is widely used by the current dewaxing precision casting industry, because it has the following advantages: (1) The process can be partially automated to save manpower and increase production rate (2) Lower production costs (3) The ceramic shell mold is thin, and the casting rate of the casting after casting is high and uniform, so the mechanical properties are better. (4) better dimensional stability A precision casting mold for stainless steel precision c

VSI sand making machine is a kind of widely used mechanical equipment, which plays an important role in the sand making, crushing and rough grinding industries, but the most used one is the sand making industry. Since the companies that produce the equipment are mostly mining machinery manufacturers, there are certain requirements for sand and gravel. 1. The particle requirements for the broken material are fine. In general, the requirements for the needle shape are not strict. The reason for the strict grain size and grain size of the ore is that the cubic sand is the best for concrete and asphalt. The machine-made sand not only increases the strength of the concrete, but also reduces the amount of cement. Secondly, the cubic sand has an interlocking effect on the particles due to the angular edges. 2. According to the definition of the mechanism sand, the rock particles with a particle size of less than 4.75 mm, which are made by mechanical crushing and sieving, are not included in

The iron ore vertical mill has high safety and reliability. Because there are no rolling bearings and screws in the grinding chamber, there is no problem of the bearing and its seal being vulnerable, or the problem of destroyin

The casting process of Raymond Mill equipment is an important factor to determine the quality of wear-resisting parts. Today, Shanghai SBM Heavy Industry Co., Ltd. Introduces three factors that affect the casting process of Raymond mill. 1. The quality of raw materials used in casting directly determines the quality of Raymond mill. For example, the quality of refractory materials, fuel, flux and casting sand is not up to standard, so that defects such as pinhole, slag inclusion and sand sticking occur in cast iron, which will affect the quality of cast iron and make cast iron scrap. 2. Reasonable process operation rules to improve the technical level of workers. In production, the quality of Raymond Mill castings should be controlled. At the same time, from raw materials, auxiliary materials to each product control and inspection process. For each process must be strictly in accordance with the process code, and finally the quality of the finished castings are inspected. Good materi

With the wear of the broken tooth plate, the discharge port gradually increases, and the particle size of the crushed product becomes thicker and thicker. In order to ensure the product size requirements, it is necessary to adjust the size of the discharge port regularly by using an adjusting device. The method of adjusting the discharge port of the jaw crusher mainly has three forms: (1) Gasket adjustment. Place a set of equal thickness spacers between the back thrust plate support and the rear wall of the frame. By increasing or decreasing the number of shim layers, the discharge port of the crusher is reduced or increased. This method can be adjusted in multiple steps, the machine structure is relatively compact, and the weight of the device can be reduced, but it must be stopped when adjusting. This type of adjustment is often used in large jaw crushers. (2) Wedge adjustment. The adjustment of the crusher discharge port is achieved by the relative movement of the two wedges betwee

Ramond grinding machine is mainly composed of main engine, fan, reducer, analysis machine, grinding roller, grinding ring, scraper, grinding roller assembly, high-pressure grinding device, plum frame, etc. From the structure of ramond mill , it can be seen that the bearing device is the core part of the equipment, the use of grinding roller and the user's operation mode has a certain relationship, but there are often users reflect the phenomenon of bearing into the powder in the mill. Now small make up for everyone to analyze the reasons. The reasons for the powder entering into the inner bearing of ramond mill can be roughly divided into two situations: one is the lack of lubricating oil or the damage of the sealing ring; Second, the bearing device for a long time lack of maintenance and cleaning. Bearing feeding powder is generally caused by these two operational problems. First, let's talk about the bearing sealing ring. Sealing ring is generally rubber products, due to the

The grinding machine produced by SBM Heavy Industry adopts the advanced structure of similar products at home and abroad, and is updated and improved on the basis of raymond mill in the same industry. This equipment has higher efficiency than ball mill, low power consumption, small floor space and low investment. . The grinding roller is tightly pressed on the grinding ring under the action of centrifugal force, so that when the grinding roller and the grinding ring are worn to a certain thickness, the yield and fineness of the finished product are not affected. The replacement cycle of the grinding roller and the grinding ring is long, so that the shortcomings of the replacement period of the wearing parts of the centrifugal pulverizer are eliminated. The air-selected airflow of the machine is circulated and flowed in the fan-grinding shell-cyclone-fan, so it has less dust than the high-speed centrifugal pulverizer, the operation workshop is clean, and the environment is pollution-fr

First, the jaw crusher The working principle of the jaw crusher is: the motor drives the belt and the pulley, and the moving jaw moves up and down through the eccentric shaft. When the moving jaw rises, the angle between the bracket and the moving jaw becomes larger, thereby pushing the movable jaw to approach the fixed jaw. At the same time, the material is crushed or chopped to achieve the purpose of crushing; when the moving down, the angle between the bracket and the moving jaw becomes smaller, and the movable jaw is separated from the fixed jaw by the action of the rod and the spring. The broken material is discharged from the lower opening of the crushing chamber. Performance characteristics of jaw crusher: large crushing ratio, uniform product size; convenient component replacement, small maintenance workload; simple structure, reliable operation, low operating cost; low noise, less dust; large range of discharge opening, can meet different User's request.
