Features of Screen Cloth (Mesh screen)
There are several types of screen clothes such as woven wire screen, punch metal, rubber screen, and grizzly bar. Choosing the suitable screen is necessary in order to improve screening efficiency.
- Woven wire screen
Plain weave and flat-top weave are mainly used for woven wire screens. However, Ton-cap weave and Tie-rod weave are also used for viscous materials and mass processing. Screens are usually made by hard steel wire, but galvanizing lines and stainless steel wire are used depending on the intended use. - Perforated metal screen
Square hole is mainly used for perforated metal screens, but there are various types available such as round hole, and Oblong. Steel board is usually used for punch metals, but High-tensile steel board and stainless steel board are also used depending on the intended use. - Rubber Screen
Square hole, round hole, and oblong are used for rubber screens. Structure of rubber screen depends on the manufacturing company. Therefore, there are products such as perforated abrasion resistance rubber board, and metallic molding type with a built in reinforcing cord and plate. - Grizzly bar

Other vibrating screens and vibrating equipment
For screening and size sorting... fastest and most even screening.
Rubber Spring Screen RSH Type
Linear vibration type screen using an unbalanced weight type vibrator and the resonant action of rubber springs. The large amplitude makes it highly efficient. The structure is easy to maintain and adjust, and the processing volume can be easily adjusted by the controller.
Electromagnetic screen VSF type
Electromagnetic vibration is applied directly to the screen attached to the frame. A small vibration source can vibrate a large area of screen. Ideal for processes with large returns.
For casting sand processing. Rapid separation of sand and product from the casting frame.
Shakeout Machine
This vibrating machine for casting sand processing efficiently separates products and sand from casting molds by applying vibration to the cast molds. The drive vibration motor can be freely adjusted in amplitude according to the size of the product to be separated and the condition of the sand. The products are conveyed from the deck plate to the next process. Operation, maintenance, and inspection are extremely easy. Ideal for streamlining sand processing lines.
Large volume feeding of medium and large lump material with bulk feeding.
Grizzly Feeder GF type
Half-wave pulsating current is used to excite an electromagnet, which is driven by high-speed and powerful vibration. It has excellent screening efficiency, and performs highly efficient roughing of large volumes of ore, crushed stone, lime, and other materials. The processing volume can be freely adjusted. Robust structure that can withstand heavy use.
Rubber Spring Grizzly Feeder RGH Type
Linear vibration type that effectively applies unbalanced weight vibrators and the resonant action of rubber springs. It is a versatile type that can carry out large-volume rough shaking with a small driving force. Of course, like the GF type, it demonstrates stable performance in any operating conditions.
RV Grizzly Feeder RVG Type
Forced vibration type with the vibrating motor mounted directly on the trough. The structure is lightweight and robust. The RVG type is also extremely stable in operation due to its high vibratory transmission efficiency to the trough and the amplitude increase phenomenon caused by material adhesion.
Strong screen ideal for sticky materials.
Wave Screen
Dynamic vibration of the screen, which alternately "tautens" and "sags", makes it ideal for screening sticky materials. The screen can be applied to a wide range of materials with high water content that are prone to clogging or sticking to the screen, and can be operated continuously.
