Material feeds into the drum, is lifted up by the rotation and aerated as it falls back down. This action is repeated with each revolution along the length of the drum. The finer material passes through the screen openings while the larger material tumbles towards its eventual exit at the rear of the drum.
The trommel screens provide a simple, efficient and economical solution to upgrade a wide rang of material and optimize the subsequent process steps of recovery. This method of screening helps to reduce operating and investment cost and to increase product quality, while allowing rapid and large volume processing.
Our Trommel screens are constructed of high quality material, designed for high performance, high production rates, lower operating costs and lower maintenance.
This material is then passed on to the downstream process equipment which can be in various forms such as centrifugal Concentrator, spirals, jigs

SZZ series of auto-centered vibrating screen is composed of mainframe, eccentric bock, screen web, rub spring, electric motor, coupler etc. It works with the eccentric of main shaft rotation when the spindle rotates, which makes the screen frame vibration of circular. By the motor force and adjusting the amplitude of the eccentric shaft, vibrating screen moves quickly like a circle. Materials in the sieve case can be seperated and screened from the sieve pore in this process.
Driven by rounding motion of vibrator, rounding vibration screen is widely applied in quarries and mines. It features adjustable amplitude, long dropping line, multiple options for screen requirements, big screen mesh with multi decks and high screen efficiency.
Through V-belt, motor drives the eccentric block to rotate with a high speed so to generate centrifugal force. Then the materials are thrown on and above the screen mesh. So the small size of products are omitted.
ZD series vibrating screen have 2 layers and 3 layers, can make screen, classification and dehydration etc. at a regular place
ZD series vibrating screen can make screen, classification and dehydration etc. at a regular place. It is mainly suitable for building sandstone plant, ore and coal dressing plant etc. The double deck screen may select out the ores in three grade. By adjusting the specification of screen mesh and screen deck, we can get final ores in different size to meet customer requirement.
We can offer specific design programme for customer including combination crusher, screen and belt conveyor, only if customer inform capacity required and size of final discharge ores.
series of high frequency electromagnetic vibrating screen(for short electromagnetic screen) is a new type of material screening equipment, it uses a new vibration mode and transmission principle, making the use of electromagneticvibrator drive system, to make the transmission system vibrating the screen ,after that the purpose is enhancing the sieve net screening efficiency. It has simple operation, stable performance, high efficiency, low power consumption, the characteristics of strong cleaning by itself.
It is used in grinding process of concentrator graded homework, under the appropriate of feeding concentrations, feeding particle size (200 mesh) , the difference between the demand level grain content screen size and feeding particle size is less than 30%,under this conditions, the screening efficiency is as high as 70% above. Due to the high screening efficiency, can greatly reduce cycle load and sieve grain that qualified level, so as to improve the capacity of millprocessing power (general it can be improved the 5-10%), when controling things under strictly in the screening process on the screen size, can eliminate the harmful effects which separating the coarse size with concentrate grain quality , The pulp under the work in high frequency vibration sieve surface small amplitude, there is the role of density stratified according to function, high density and small particles is easy to settlement to the bottom of material, thus obviously improve the grade of concentrates.
(1) The surface of screen is high frequency vibrating, the screen box is fixed, the working principle is fixed the balance between the elastic vibration of the system and the elastic force vibration force reaction in the screen box,so do the screen box is fixed.
(2) The surface of screen is high frequency vibrating, the frequency is 50HZ,the range of vibrating is 1-2mm, the strength of vibrating will be 8-10 times acceleration speed, compare with ordinary vibrating screen ,it is as high as 2-3 times, the characteristics of strong cleaning by itself, high screening efficiency,large capactiy, it is comfortable to screen, dehydration ,grade the size from 0.074-3mm in the slime material ore.
(3) The surface of screen consists of three different flexible screens, the bottom of steel wire core polyurethane nets,contacted with vibrating device directly,there are two layer of composite nets which make in the stainless steel ,the top of composite contact with material ore, the requirement of the top net is making sure the size depending on the screening system, the high opening rate in the screens, it owns a certain siffness.
(4) The sieve machine installation angle could be adjustment in convenient at any time , be adapted in different material properties and different screening homework. Regarding to the wet method of concentrator screening installation angle is generally in 25 degrees positive and negative 2 degrees range , dry screening installation angle is commonly in 33 degrees positive and negative 2 degrees range.
(5) The sieve machine vibration parameters by using the computer integrated control, can be software establishment to each of the vibration system vibration parameters, in addition to the general operating mode vibration parameters, and the continuous instantaneous strength vibrating at any time, keep clear to the screen hole to prevent blocking.
(6) The special design of the electromagnetic vibration system is using the rubber mainly vibration spring, rubber, rubber bearing spring hinge, it has long-term continuous operation reliable working, low consumption, each of the electromagnetic vibration power is only 0.15 KW, the dressing generally use the ZDS2020 type of high frequency electromagnetic screening, the installed power is only 1.2 KW. The sieve machine is belong to energy-saving products.
(7) Sieve machine have single channel and double channel , single layer and layers ect.many different structure forms, designing in modular, can design in flexible according to the specific applications .
Sand and gravel washers are also called ore washer which are used to wash ores with mud before the employment of mineral processing technology as well as increase ore dressing indexes of back-end technology. They are often used to wash cores such as manganese ore, iron ore, limestone, tungsten ore, tin ore and silica sand ore. According to silt content, grain size and washing difficulty level of cores, double-screw washer, troughed ore washer or cylindrical ore washer can be selected. Sand and gravel washers are also used to wash sand and gravel in construction sites, power stations, etc. RXT sand and gravel washers introduce foreign technology and apply to desliming of sand and gravel. Single-deck or double-deck round screen is installed inside the drum of the washer which can get two or three types of sand and gravel production of different specifications.
