Each type of the SBM grinding machine serves a particular role in the material processing and milling industry:
Cone Crusher
The cone-shaped cone crusher is composed of a fixed outer cone and a rotating inner cone. The SBM cone grinding machine functions on the principle of compression and similar forces. The SBM cone crushing machine works by compressing the material against the inner cone that moves up and down. The material is crushed when the gap between the cones narrows. The cone crusher typically processes medium-hard to hard stones. It makes them suitable for finer crushing stages after preliminary crushing by jaw crushers. The cone crushers have 2 main types: spring and hydraulic, depending on the specific feature of the SBM machine.
Hammer Crusher
An SBM hammer crusher grinding machine has a large cylindrical rotor. It is equipped with several sets of swinging hammers. The rotor revolves at high speeds to strike the hammers against the material. This process breaks the material down into smaller pieces through high-speed impact. The hammer mill has extensive applications in stone processing. It can also fragment soft and moderately hard materials like limestone, gypsum, etc.
Jet Mill
Jet mills are sometimes called air mills. It can sharply reduce the size of the particles of the material with the help of compressed air. The crushed particles can have finer dimensions, sometimes reaching an end product with up to 95% of particles measuring less than 10 microns. Jet mills have extensive applications in the chemical and pharmaceutical industries. Clients use it to grind materials like polymers, pigments, carbon compounds, etc. The materials can also include organic compounds like cellulose, starch, microcrystalline, etc.
Roller Mill
An SBM roller mill grinding machine is manufactured with two or more parallel rolls. The rolls turn in opposite directions. The material gets crushed into smaller pieces when it passes between the gaps of the rotating roller. Roller mills can be used for crushing grains, oilseeds, fodder, and other materials.
LM Series Vertical Mill
Vertical grinder mills have become famous for grinding cement, slag, lime, and other materials. The mill comprises a static disc and a dynamically revolving disc. The roller presses the discs. Larger pieces of the material and cement clinkers are crushed into smaller ones. The vertical mill has a high grinding efficiency and occupies a small space. It is also very energy efficient. An LM series vertical mill of the SBM can also be used to grind nonmetallic minerals and coal, among other things.
SCM Series Superfine Mill
The feed material is milled in a closed-circuit system. The specific feature of the mills is an impeller classifier. It is designed in the mill itself and is a combination of classification and grinding operations. According to the working method, the mills are termed as air classifier mills or classifying mills.
MBSZ Series Rod Mill
Rod mills are similar to ball mills but use thinner rods as their grinding media instead of balls. The rods of a particular length are used to avoid over-crushing the material. The mills are suitable for mineral processing and sand making.
The specifications of SBM mills vary with the different types and models. The following table shows some specifications for SBM grinding machines.
The above specifications may vary depending on model variations. Other specifications are available on request.
Maintenance:
An efficient way to maintain the grinding machine is to use a preventive maintenance program. It helps to detect failures and faults early so as to improve reliability. The program reduces any unplanned stoppages by ensuring routine inspection and servicing is done.
The device can be cleaned easily and the filter changed to maintain hygiene. Before starting the cleaning process, it is important to check the electrical connections and those parts not to be disconnected. SBM coffee grinding machines have exposed parts that can be cleaned using a dry cloth or air compressor to remove dirt and dust. Regular parts inspections greatly help to identify signs of wear, loosening, and clogs. Familiarization with service manuals and assembly diagrams will offer guidance on areas that need maintenance and cleaning frequently.
After making any adjustments or repairs, users should break in the grinding machine first. Gradually immerse it into load rather than exposing it to maximum load right after repair. During the first few days of operation after repair, monitor the functioning closely to observe if there are any unusual noises or movements. They can indicate that parts may need further adjustment, realignment, or replacement. Maintain a fixed schedule and stay organized while handling routine maintenance tasks. Users can create a maintenance log and display a task schedule. It will ensure that critical tasks are not overlooked and it can also assist the future service team.
The purpose of the SBM grinding machine goes beyond just producing flour for daily bread. It serves many different industries and business sectors, including the following.
Capacity
Business buyers should first determine their production volume and grinding requirements. They must choose an SBM grinding machine with a capacity that meets business needs to avoid frequent equipment downtime or over capacity.
Raw materials
Consider the type and characteristics of the raw materials to be ground, such as hardness, moisture, particle size, etc. Choose an SBM grinding machine suitable for processing specific raw materials to ensure stable production and product quality.
Automation and control
Consider the degree of automation and control features of the grinding equipment. An SBM machine with automated control and a user-friendly interface can improve production efficiency and ease of operation and management.
Layout and size
Consider the installation space within the production line. Ensure that the dimensions and layout of the chosen grinding machine will fit the available space and consider the equipment's accessibility for maintenance and repair.
Energy efficiency
Select an energy-efficient grinding machine to help reduce operating costs and environmental impact. Consider energy-saving modes, power consumption, and efficiency during operation.
Investment and cost
Consider the initial equipment investment and operating costs, including energy consumption, maintenance, and replacement parts costs. Perform a cost-benefit analysis and make an economically viable decision.
Q: What are the types of SBM in the market?
A: There are two main types of SBM: hammer mills and impact crushers. Hammer mill grinders use high-speed hammers to crush and break down materials. They are suitable for processing softer minerals. Impact crusher grinders utilize high-speed rotors with blow bars to strike and break materials. They are ideal for harder and more abrasive minerals.
Q: How does the grinding capacity of an SBM determine its performance?
A: The grinding capacity of an SBM refers to the quantity of material it can process in a given time. It is usually indicated in tons per hour. The capacity is determined by several factors, including the size and power of the motor, the dimensions of the feed opening and the product discharge, the design of the grinding chamber, and the type of material being crushed and ground.
Q: Is it safe to use an SBM without any safety features?
A: Safety features like overload protection, emergency stop buttons, and vibration dampening are crucial to ensuring the safety of operators and equipment. The function of these features cannot be overemphasized. Operators must do everything possible to avoid accidents or equipment failure.
Q: What are some signs that an SBM needs maintenance?
A: An increase in energy consumption, unusual noises, reduced processing efficiency, and frequent breakdowns are typical signs that an SBM requires maintenance.
