Frequently Asked Questions

Our machines quality is comparable to HOSOKAWA ALPINE and NETZSCH, but the price is only about one-fifth. Since more than 3,000 customers have chosen us, I believe you will not be wrong. You are welcome to visit the factory on site.

In addition to the main engine and classifier, it also includes cyclone separators, dust collectors, induced draft fans and electric control cabinets, wires and cables, and compressed air sources. We can provide a complete set of production lines ready to use.

The capacity of the equipment is related to the hardness, moisture, density, grindability, fluidity and other indicators of the material. The output of different materials produced by the same equipment varies greatly. For the same material, different equipment particle sizes can also cause large differences in output. Please provide the nature and detailed requirements of the materials, and our engineers will provide you with equipment selection and solutions.

Each has its own advantages and disadvantages, which should be selected according to the specific requirements of materials.

The fluidized bed jet mill is equipped with a precision grading wheel, which is more convenient to adjust the particle size of the disc jet mill. The equipment has a finer particle size, but it is more troublesome to disassemble and clean, and the equipment investment is also higher.

The disc jet mill has higher output, lower energy consumption and lower equipment investment while meeting the granularity.

The horizontal grading wheel has high grading accuracy and high stability, and is suitable for equipment with high requirements for Dmax (vertex cutting). The shaft of the transmission system of the vertical classifying wheel is too long, resulting in limited speed and relatively low energy consumption, but the top cut of the particle size is not as good as the horizontal classifying wheel, which is suitable for the case where the classification particle size is relatively low.

Belt drive is a common practice in the industry. High speed can be achieved through the speed ratio design of the pulley. The motor can be a standard motor, which has low motor price, low failure rate and convenient maintenance. If a high-speed direct-connected motor is used, because the motor is a non-standard equipment, special customization is required, the price is high, the failure rate is high, the number of manufacturers to choose from is limited, and the maintenance service is more troublesome. Therefore, our company recommends belt drive, but it can also provide direct motor drive.

With cyclone is the standard configuration of crusher and classifier. If the requirements for fine powder of materials are relatively high, the cyclone can drive part of the fine powder into the dust collector. The content of ultra-fine powder in the cyclone collection equipment is reduced, and the particle size distribution will be narrower, but it will increase the cost and space. The equipment collected by the cyclone and the dust collector are two kinds of materials with different thicknesses, which need to be selected according to your actual needs.

The general collection efficiency is 90-95%, up to 98%-99%. The collection efficiency is related to the particle size, density, moisture, fluidity, etc. of the material, which requires specific analysis of specific circumstances, and cannot be generalized.

At present, the dust collector used in the crusher industry is mainly of filter bag type, and in special cases, filter cartridge type or plastic sintered plate type is also used. However, the latter two forms are more expensive and have certain defects. They are not recommended for use under special circumstances.

The domestic filter bag material can efficiently collect particles above 2 microns after being coated with a filtration accuracy of 99.99%. For equipment with a high content of fine powders below 2 microns, it is better to use a plastic sintered plate dust collector.

The jet mill is a device that can achieve extremely fine particle size by dry pulverization. The gas stream can be compressed gas or superheated steam. The limit particle size achieved by compressed gas pulverization is about D50: 2 microns, and the limit particle size achieved by superheated steam pulverization is about D50: 1 micron. Some materials can reach sub-micron level, that is, between 0.1 micron and 1 micron.

The biggest disadvantage of the jet mill using compressed air as the medium is the high energy consumption, and it is not recommended to apply non-high value-added equipment. The jet mill has the advantages of low temperature rise, fine particle size and high purity, which is the best choice for the production of high value-added materials.

Our company will choose different materials according to the nature of your materials, such as carbon steel, stainless steel (304, 316, 316L...), etc. Some key components will use special materials as needed, such as alumina ceramics, zirconia ceramics, and nitrogen. Silicon carbide ceramics, silicon carbide ceramics, etc., can also be selected from imported alloy materials with high wear resistance.

Our company is a non-standard customized equipment, which can be manufactured only after confirming the drawing, signing and sealing and paying the deposit according to the contract or technical agreement. Under special circumstances, both parties can coordinate the handling. I hope that your company will handle it as soon as possible, so as not to affect the delivery.
